How do I detect a click outside an element?

I have some HTML menus, which I show completely when a user clicks on the head of these menus. I would like to hide these elements when the user clicks outside the menus' area.

Is something like this possible with jQuery?

$("#menuscontainer").clickOutsideThisElement(function() {
    // Hide the menus
});

Answer

NOTE: Using stopEventPropagation() is something that should be avoided as it breaks normal event flow in the DOM. See this article for more information. Consider using this method instead

Attach a click event to the document body which closes the window. Attach a separate click event to the container which stops propagation to the document body.

$(window).click(function() {
//Hide the menus if visible
});

$('#menucontainer').click(function(event){
    event.stopPropagation();
});
Answer

You can listen for a click event on document and then make sure #menucontainer is not an ancestor or the target of the clicked element by using .closest().

If it is not, then the clicked element is outside of the #menucontainer and you can safely hide it.

$(document).click(function(event) { 
  $target = $(event.target);
  if(!$target.closest('#menucontainer').length && 
  $('#menucontainer').is(":visible")) {
    $('#menucontainer').hide();
  }        
});

Edit – 2017-06-23

You can also clean up after the event listener if you plan to dismiss the menu and want to stop listening for events. This function will clean up only the newly created listener, preserving any other click listeners on document. With ES2015 syntax:

export function hideOnClickOutside(selector) {
  const outsideClickListener = (event) => {
    $target = $(event.target);
    if (!$target.closest(selector).length && $(selector).is(':visible')) {
        $(selector).hide();
        removeClickListener();
    }
  }

  const removeClickListener = () => {
    document.removeEventListener('click', outsideClickListener)
  }

  document.addEventListener('click', outsideClickListener)
}

Edit – 2018-03-11

For those who don't want to use jQuery. Here's the above code in plain vanillaJS (ECMAScript6).

function hideOnClickOutside(element) {
    const outsideClickListener = event => {
        if (!element.contains(event.target) && isVisible(element)) { // or use: event.target.closest(selector) === null
          element.style.display = 'none'
          removeClickListener()
        }
    }

    const removeClickListener = () => {
        document.removeEventListener('click', outsideClickListener)
    }

    document.addEventListener('click', outsideClickListener)
}

const isVisible = elem => !!elem && !!( elem.offsetWidth || elem.offsetHeight || elem.getClientRects().length ) // source (2018-03-11): https://github.com/jquery/jquery/blob/master/src/css/hiddenVisibleSelectors.js 

NOTE: This is based on Alex comment to just use !element.contains(event.target) instead of the jQuery part.

But element.closest() is now also available in all major browsers (the W3C version differs a bit from the jQuery one). Polyfills can be found here: Element.closest()

How to detect a click outside an element?

The reason that this question is so popular and has so many answers is that it is deceptively complex. After almost eight years and dozens of answers, I am genuinely surprised to see how little care has been given to accessibility.

I would like to hide these elements when the user clicks outside the menus' area.

This is a noble cause and is the actual issue. The title of the question—which is what most answers appear to attempt to address—contains an unfortunate red herring.

Hint: it's the word "click"!

You don't actually want to bind click handlers.

If you're binding click handlers to close the dialog, you've already failed. The reason you've failed is that not everyone triggers click events. Users not using a mouse will be able to escape your dialog (and your pop-up menu is arguably a type of dialog) by pressing Tab, and they then won't be able to read the content behind the dialog without subsequently triggering a click event.

So let's rephrase the question.

How does one close a dialog when a user is finished with it?

This is the goal. Unfortunately, now we need to bind the userisfinishedwiththedialog event, and that binding isn't so straightforward.

So how can we detect that a user has finished using a dialog?

focusout event

A good start is to determine if focus has left the dialog.

Hint: be careful with the blur event, blur doesn't propagate if the event was bound to the bubbling phase!

jQuery's focusout will do just fine. If you can't use jQuery, then you can use blur during the capturing phase:

element.addEventListener('blur', ..., true);
//                       use capture: ^^^^

Also, for many dialogs you'll need to allow the container to gain focus. Add tabindex="-1" to allow the dialog to receive focus dynamically without otherwise interrupting the tabbing flow.

$('a').on('click', function () {
  $(this.hash).toggleClass('active').focus();
});

$('div').on('focusout', function () {
  $(this).removeClass('active');
});
div {
  display: none;
}
.active {
  display: block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="#example">Example</a>
<div id="example" tabindex="-1">
  Lorem ipsum <a href="http://example.com">dolor</a> sit amet.
</div>


If you play with that demo for more than a minute you should quickly start seeing issues.

The first is that the link in the dialog isn't clickable. Attempting to click on it or tab to it will lead to the dialog closing before the interaction takes place. This is because focusing the inner element triggers a focusout event before triggering a focusin event again.

The fix is to queue the state change on the event loop. This can be done by using setImmediate(...), or setTimeout(..., 0) for browsers that don't support setImmediate. Once queued it can be cancelled by a subsequent focusin:

$('.submenu').on({
  focusout: function (e) {
    $(this).data('submenuTimer', setTimeout(function () {
      $(this).removeClass('submenu--active');
    }.bind(this), 0));
  },
  focusin: function (e) {
    clearTimeout($(this).data('submenuTimer'));
  }
});

$('a').on('click', function () {
  $(this.hash).toggleClass('active').focus();
});

$('div').on({
  focusout: function () {
    $(this).data('timer', setTimeout(function () {
      $(this).removeClass('active');
    }.bind(this), 0));
  },
  focusin: function () {
    clearTimeout($(this).data('timer'));
  }
});
div {
  display: none;
}
.active {
  display: block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="#example">Example</a>
<div id="example" tabindex="-1">
  Lorem ipsum <a href="http://example.com">dolor</a> sit amet.
</div>

The second issue is that the dialog won't close when the link is pressed again. This is because the dialog loses focus, triggering the close behavior, after which the link click triggers the dialog to reopen.

Similar to the previous issue, the focus state needs to be managed. Given that the state change has already been queued, it's just a matter of handling focus events on the dialog triggers:

This should look familiar
$('a').on({
  focusout: function () {
    $(this.hash).data('timer', setTimeout(function () {
      $(this.hash).removeClass('active');
    }.bind(this), 0));
  },
  focusin: function () {
    clearTimeout($(this.hash).data('timer'));  
  }
});

$('a').on('click', function () {
  $(this.hash).toggleClass('active').focus();
});

$('div').on({
  focusout: function () {
    $(this).data('timer', setTimeout(function () {
      $(this).removeClass('active');
    }.bind(this), 0));
  },
  focusin: function () {
    clearTimeout($(this).data('timer'));
  }
});

$('a').on({
  focusout: function () {
    $(this.hash).data('timer', setTimeout(function () {
      $(this.hash).removeClass('active');
    }.bind(this), 0));
  },
  focusin: function () {
    clearTimeout($(this.hash).data('timer'));  
  }
});
div {
  display: none;
}
.active {
  display: block;
}

</div>


Esc key

If you thought you were done by handling the focus states, there's more you can do to simplify the user experience.

This is often a "nice to have" feature, but it's common that when you have a modal or popup of any sort that the Esc key will close it out.

keydown: function (e) {
  if (e.which === 27) {
    $(this).removeClass('active');
    e.preventDefault();
  }
}

$('a').on('click', function () {
  $(this.hash).toggleClass('active').focus();
});

$('div').on({
  focusout: function () {
    $(this).data('timer', setTimeout(function () {
      $(this).removeClass('active');
    }.bind(this), 0));
  },
  focusin: function () {
    clearTimeout($(this).data('timer'));
  },
  keydown: function (e) {
    if (e.which === 27) {
      $(this).removeClass('active');
      e.preventDefault();
    }
  }
});

$('a').on({
  focusout: function () {
    $(this.hash).data('timer', setTimeout(function () {
      $(this.hash).removeClass('active');
    }.bind(this), 0));
  },
  focusin: function () {
    clearTimeout($(this.hash).data('timer'));  
  }
});
div {
  display: none;
}
.active {
  display: block;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="#example">Example</a>
<div id="example" tabindex="-1">
  Lorem ipsum <a href="http://example.com">dolor</a> sit amet.
</div>


If you know you have focusable elements within the dialog, you won't need to focus the dialog directly. If you're building a menu, you could focus the first menu item instead.

click: function (e) {
  $(this.hash)
    .toggleClass('submenu--active')
    .find('a:first')
    .focus();
  e.preventDefault();
}

$('.menu__link').on({
  click: function (e) {
    $(this.hash)
      .toggleClass('submenu--active')
      .find('a:first')
      .focus();
    e.preventDefault();
  },
  focusout: function () {
    $(this.hash).data('submenuTimer', setTimeout(function () {
      $(this.hash).removeClass('submenu--active');
    }.bind(this), 0));
  },
  focusin: function () {
    clearTimeout($(this.hash).data('submenuTimer'));  
  }
});

$('.submenu').on({
  focusout: function () {
    $(this).data('submenuTimer', setTimeout(function () {
      $(this).removeClass('submenu--active');
    }.bind(this), 0));
  },
  focusin: function () {
    clearTimeout($(this).data('submenuTimer'));
  },
  keydown: function (e) {
    if (e.which === 27) {
      $(this).removeClass('submenu--active');
      e.preventDefault();
    }
  }

WAI-ARIA Roles and Other Accessibility Support

This answer hopefully covers the basics of accessible keyboard and mouse support for this feature, but as it's already quite sizable I'm going to avoid any discussion of WAI-ARIA roles and attributes, however I highly recommend that implementers refer to the spec for details on what roles they should use and any other appropriate attributes.

Answer

The other solutions here didn't work for me so I had to use:

if(!$(event.target).is('#foo'))
{
    // hide menu
}
Answer

I have an application that works similarly to Eran's example, except I attach the click event to the body when I open the menu... Kinda like this:

$('#menucontainer').click(function(event) {
  $('html').one('click',function() {
    // Hide the menus
  });

  event.stopPropagation();
});

Answer

After research I have found three working solutions (I forgot the page links for reference)

First solution

<script>
    //The good thing about this solution is it doesn't stop event propagation.

    var clickFlag = 0;
    $('body').on('click', function () {
        if(clickFlag == 0) {
            console.log('hide element here');
            /* Hide element here */
        }
        else {
            clickFlag=0;
        }
    });
    $('body').on('click','#testDiv', function (event) {
        clickFlag = 1;
        console.log('showed the element');
        /* Show the element */
    });
</script>

Second solution

<script>
    $('body').on('click', function(e) {
        if($(e.target).closest('#testDiv').length == 0) {
           /* Hide dropdown here */
        }
    });
</script>

Third solution

<script>
    var specifiedElement = document.getElementById('testDiv');
    document.addEventListener('click', function(event) {
        var isClickInside = specifiedElement.contains(event.target);
        if (isClickInside) {
          console.log('You clicked inside')
        }
        else {
          console.log('You clicked outside')
        }
    });
</script>
Answer
$("#menuscontainer").click(function() {
    $(this).focus();
});
$("#menuscontainer").blur(function(){
    $(this).hide();
});

Works for me just fine.

Answer

Now there is a plugin for that: outside events (blog post)

The following happens when a clickoutside handler (WLOG) is bound to an element:

  • the element is added to an array which holds all elements with clickoutside handlers
  • a (namespaced) click handler is bound to the document (if not already there)
  • on any click in the document, the clickoutside event is triggered for those elements in that array that are not equal to or a parent of the click-events target
  • additionally, the event.target for the clickoutside event is set to the element the user clicked on (so you even know what the user clicked, not just that he clicked outside)

So no events are stopped from propagation and additional click handlers may be used "above" the element with the outside-handler.

Answer

This worked for me perfectly!!

$('html').click(function (e) {
    if (e.target.id == 'YOUR-DIV-ID') {
        //do something
    } else {
        //do something
    }
});
Answer

I don't think what you really need is to close the menu when the user clicks outside; what you need is for the menu to close when the user clicks anywhere at all on the page. If you click on the menu, or off the menu it should close right?

Finding no satisfactory answers above prompted me to write this blog post the other day. For the more pedantic, there are a number of gotchas to take note of:

  1. If you attach a click event handler to the body element at click time be sure to wait for the 2nd click before closing the menu, and unbinding the event. Otherwise the click event that opened the menu will bubble up to the listener that has to close the menu.
  2. If you use event.stopPropogation() on a click event, no other elements in your page can have a click-anywhere-to-close feature.
  3. Attaching a click event handler to the body element indefinitely is not a performant solution
  4. Comparing the target of the event, and its parents to the handler's creator assumes that what you want is to close the menu when you click off it, when what you really want is to close it when you click anywhere on the page.
  5. Listening for events on the body element will make your code more brittle. Styling as innocent as this would break it: body { margin-left:auto; margin-right: auto; width:960px;}
Answer

As another poster said there are a lot of gotchas, especially if the element you are displaying (in this case a menu) has interactive elements. I've found the following method to be fairly robust:

$('#menuscontainer').click(function(event) {
    //your code that shows the menus fully

    //now set up an event listener so that clicking anywhere outside will close the menu
    $('html').click(function(event) {
        //check up the tree of the click target to check whether user has clicked outside of menu
        if ($(event.target).parents('#menuscontainer').length==0) {
            // your code to hide menu

            //this event listener has done its job so we can unbind it.
            $(this).unbind(event);
        }

    })
});
Answer

A simple solution for the situation is:

$(document).mouseup(function (e)
{
    var container = $("YOUR SELECTOR"); // Give you class or ID

    if (!container.is(e.target) &&            // If the target of the click is not the desired div or section
        container.has(e.target).length === 0) // ... nor a descendant-child of the container
    {
        container.hide();
    }
});

The above script will hide the div if outside of the div click event is triggered.

Answer

Solution1

Instead of using event.stopPropagation() which can have some side affects, just define a simple flag variable and add one if condition. I tested this and worked properly without any side affects of stopPropagation:

var flag = "1";
$('#menucontainer').click(function(event){
    flag = "0"; // flag 0 means click happened in the area where we should not do any action
});

$('html').click(function() {
    if(flag != "0"){
        // Hide the menus if visible
    }
    else {
        flag = "1";
    }
});

Solution2

With just a simple if condition:

$(document).on('click', function(event){
    var container = $("#menucontainer");
    if (!container.is(event.target) &&            // If the target of the click isn't the container...
        container.has(event.target).length === 0) // ... nor a descendant of the container
    {
        // Do whatever you want to do when click is outside the element
    }
});
Answer

Check the window click event target (it should propagate to the window, as long as it's not captured anywhere else), and ensure that it's not any of the menu elements. If it's not, then you're outside your menu.

Or check the position of the click, and see if it's contained within the menu area.

Answer

I've had success with something like this:

var $menuscontainer = ...;

$('#trigger').click(function() {
  $menuscontainer.show();

  $('body').click(function(event) {
    var $target = $(event.target);

    if ($target.parents('#menuscontainer').length == 0) {
      $menuscontainer.hide();
    }
  });
});

The logic is: when #menuscontainer is shown, bind a click handler to the body that hides #menuscontainer only if the target (of the click) isn't a child of it.

Answer

As a variant:

var $menu = $('#menucontainer');
$(document).on('click', function (e) {

    // If element is opened and click target is outside it, hide it
    if ($menu.is(':visible') && !$menu.is(e.target) && !$menu.has(e.target).length) {
        $menu.hide();
    }
});

It has no problem with stopping event propagation and better supports multiple menus on the same page where clicking on a second menu while a first is open will leave the first open in the stopPropagation solution.

Answer

The event has a property called event.path of the element which is a "static ordered list of all its ancestors in tree order". To check if an event originated from a specific DOM element or one of its children, just check the path for that specific DOM element. It can also be used to check multiple elements by logically ORing the element check in the some function.

$("body").click(function() {
  target = document.getElementById("main");
  flag = event.path.some(function(el, i, arr) {
    return (el == target)
  })
  if (flag) {
    console.log("Inside")
  } else {
    console.log("Outside")
  }
});
#main {
  display: inline-block;
  background:yellow;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="main">
  <ul>
    <li>Test-Main</li>
    <li>Test-Main</li>
    <li>Test-Main</li>
    <li>Test-Main</li>
    <li>Test-Main</li>
  </ul>
</div>
<div id="main2">
  Outside Main
</div>

So for your case It should be

$("body").click(function() {
  target = $("#menuscontainer")[0];
  flag = event.path.some(function(el, i, arr) {
    return (el == target)
  });
  if (!flag) {
    // Hide the menus
  }
});
Answer

I found this method in some jQuery calendar plugin.

function ClickOutsideCheck(e)
{
  var el = e.target;
  var popup = $('.popup:visible')[0];
  if (popup==undefined)
    return true;

  while (true){
    if (el == popup ) {
      return true;
    } else if (el == document) {
      $(".popup").hide();
      return false;
    } else {
      el = $(el).parent()[0];
    }
  }
};

$(document).bind('mousedown.popup', ClickOutsideCheck);
Answer

Here is the vanilla JavaScript solution for future viewers.

Upon clicking any element within the document, if the clicked element's id is toggled, or the hidden element is not hidden and the hidden element does not contain the clicked element, toggle the element.

(function () {
    "use strict";
    var hidden = document.getElementById('hidden');
    document.addEventListener('click', function (e) {
        if (e.target.id == 'toggle' || (hidden.style.display != 'none' && !hidden.contains(e.target))) hidden.style.display = hidden.style.display == 'none' ? 'block' : 'none';
    }, false);
})();

(function () {
    "use strict";
    var hidden = document.getElementById('hidden');
    document.addEventListener('click', function (e) {
        if (e.target.id == 'toggle' || (hidden.style.display != 'none' && !hidden.contains(e.target))) hidden.style.display = hidden.style.display == 'none' ? 'block' : 'none';
    }, false);
})();
<a href="javascript:void(0)" id="toggle">Toggle Hidden Div</a>
<div id="hidden" style="display: none;">This content is normally hidden. click anywhere other than this content to make me disappear</div>

If you are going to have multiple toggles on the same page you can use something like this:

  1. Add the class name hidden to the collapsible item.
  2. Upon document click, close all hidden elements which do not contain the clicked element and are not hidden
  3. If the clicked element is a toggle, toggle the specified element.

(function () {
    "use strict";
    var hiddenItems = document.getElementsByClassName('hidden'), hidden;
    document.addEventListener('click', function (e) {
        for (var i = 0; hidden = hiddenItems[i]; i++) {
            if (!hidden.contains(e.target) && hidden.style.display != 'none')

I am surprised nobody actually acknowledged focusout event:

var button = document.getElementById('button');
button.addEventListener('click', function(e){
  e.target.style.backgroundColor = 'green';
});
button.addEventListener('focusout', function(e){
  e.target.style.backgroundColor = '';
});

If you are scripting for IE and FF 3.* and you just want to know if the click occured within a certain box area, you could also use something like:

this.outsideElementClick = function(objEvent, objElement){   
var objCurrentElement = objEvent.target || objEvent.srcElement;
var blnInsideX = false;
var blnInsideY = false;

if (objCurrentElement.getBoundingClientRect().left >= objElement.getBoundingClientRect().left && objCurrentElement.getBoundingClientRect().right <= objElement.getBoundingClientRect().right)
    blnInsideX = true;

if (objCurrentElement.getBoundingClientRect().top >= objElement.getBoundingClientRect().top && objCurrentElement.getBoundingClientRect().bottom <= objElement.getBoundingClientRect().bottom)
    blnInsideY = true;

if (blnInsideX && blnInsideY)
    return false;
else
    return true;}
Answer

Instead using flow interruption, blur/focus event or any other tricky technics, simply match event flow with element's kinship:

$(document).on("click.menu-outside", function(event){
    // Test if target and it's parent aren't #menuscontainer
    // That means the click event occur on other branch of document tree
    if(!$(event.target).parents().andSelf().is("#menuscontainer")){
        // Click outisde #menuscontainer
        // Hide the menus (but test if menus aren't already hidden)
    }
});

To remove click outside event listener, simply:

$(document).off("click.menu-outside");
Answer

Use:

var go = false;
$(document).click(function(){
    if(go){
        $('#divID').hide();
        go = false;
    }
})

$("#divID").mouseover(function(){
    go = false;
});

$("#divID").mouseout(function (){
    go = true;
});

$("btnID").click( function(){
    if($("#divID:visible").length==1)
        $("#divID").hide(); // Toggle
    $("#divID").show();
});
Answer

Here is a simple solution by pure javascript. It is up-to-date with ES6:

var isMenuClick = false;
var menu = document.getElementById('menuscontainer');
document.addEventListener('click',()=>{
    if(!isMenuClick){
       //Hide the menu here
    }
    //Reset isMenuClick 
    isMenuClick = false;
})
menu.addEventListener('click',()=>{
    isMenuClick = true;
})
Answer

Hook a click event listener on the document. Inside the event listener, you can look at the event object, in particular, the event.target to see what element was clicked:

$(document).click(function(e){
    if ($(e.target).closest("#menuscontainer").length == 0) {
        // .closest can help you determine if the element 
        // or one of its ancestors is #menuscontainer
        console.log("hide");
    }
});
Answer
$(document).click(function() {
    $(".overlay-window").hide();
});
$(".overlay-window").click(function() {
    return false;
});

If you click on the document, hide a given element, unless you click on that same element.

Answer

Upvote for the most popular answer, but add

&& (e.target != $('html').get(0)) // ignore the scrollbar

so, a click on a scroll bar does not [hide or whatever] your target element.

Answer

For easier use, and more expressive code, I created a jQuery plugin for this:

$('div.my-element').clickOut(function(target) { 
    //do something here... 
});

Note: target is the element the user actually clicked. But callback is still executed in the context of the original element, so you can utilize this as you'd expect in a jQuery callback.

Plugin:

$.fn.clickOut = function (parent, fn) {
    var context = this;
    fn = (typeof parent === 'function') ? parent : fn;
    parent = (parent instanceof jQuery) ? parent : $(document);

    context.each(function () {
        var that = this;
        parent.on('click', function (e) {
            var clicked = $(e.target);
            if (!clicked.is(that) && !clicked.parents().is(that)) {
                if (typeof fn === 'function') {
                    fn.call(that, clicked);
                }
            }
        });

    });
    return context;
};

By default, the click event listener is placed on the document. However, if you want to limit the event listener scope, you can pass in a jQuery object representing a parent level element that will be the top parent at which clicks will be listened to. This prevents unnecessary document level event listeners. Obviously, it won't work unless the parent element supplied is a parent of your initial element.

Use like so:

$('div.my-element').clickOut($('div.my-parent'), function(target) { 
    //do something here...
});
Answer

I did it like this in YUI 3:

// Detect the click anywhere other than the overlay element to close it.
Y.one(document).on('click', function (e) {
    if (e.target.ancestor('#overlay') === null && e.target.get('id') != 'show' && overlay.get('visible') == true) {
        overlay.hide();
    }
});

I am checking if ancestor is not the widget element container,
if target is not which open the widget/element,
if widget/element I want to close is already open (not that important).

If someone curious here is javascript solution(es6):

window.addEventListener('mouseup', e => {
        if (e.target != yourDiv && e.target.parentNode != yourDiv) {
            yourDiv.classList.remove('show-menu');
            //or yourDiv.style.display = 'none';
        }
    })

and es5, just in case:

window.addEventListener('mouseup', function (e) {
if (e.target != yourDiv && e.target.parentNode != yourDiv) {
    yourDiv.classList.remove('show-menu'); 
    //or yourDiv.style.display = 'none';
}

});

Answer

I have used below script and done with jQuery.

jQuery(document).click(function(e) {
    var target = e.target; //target div recorded
    if (!jQuery(target).is('#tobehide') ) {
        jQuery(this).fadeOut(); //if the click element is not the above id will hide
    }
})

Below find the HTML code

<div class="main-container">
<div> Hello I am the title</div>
<div class="tobehide">I will hide when you click outside of me</div>
</div>
