Consider I have a list of questions. When I click on the first question, it should automatically take me to the bottom of the page.
For a matter of fact, I do know that this can be done using jQuery.
So, could you provide me with some documentation or some links where I can find answer to this question?
EDIT: Need to scroll to a particular HTML element at the bottom of the page
jQuery isn't necessary. Most of the top results I got from a Google search gave me this answer:
window.scrollTo(0,document.body.scrollHeight);
Where you have nested elements, the document might not scroll. In this case, you need to target the element that scrolls and use it's scroll height instead.
window.scrollTo(0,document.querySelector(".scrollingContainer").scrollHeight);
You can tie that to the onclick
event of your question (i.e. <div onclick="ScrollToBottom()" ...
).
Some additional sources you can take a look at:
If you want to scroll entire page to the bottom:
var scrollingElement = (document.scrollingElement || document.body);
scrollingElement.scrollTop = scrollingElement.scrollHeight;
See the sample on JSFiddle
If you want to scroll an element to the bottom:
function gotoBottom(id){
var element = document.getElementById(id);
element.scrollTop = element.scrollHeight - element.clientHeight;
}
And that's how it works:
Ref: scrollTop, scrollHeight, clientHeight
UPDATE: Latest versions of Chrome (61+) and Firefox does not support scrolling of body, see: https://dev.opera.com/articles/fixing-the-scrolltop-bug/
Vanilla JS implementation:
element.scrollIntoView(false);
https://developer.mozilla.org/en-US/docs/Web/API/element.scrollIntoView
You can use this to go down the page in an animation format.
$('html,body').animate({scrollTop: document.body.scrollHeight},"fast");
Below should be the cross browser solution. It has been tested on Chrome, Firefox, Safari and IE11
window.scrollTo(0, document.body.scrollHeight || document.documentElement.scrollHeight);
window.scrollTo(0,document.body.scrollHeight); doesn't work on Firefox, at least for Firefox 37.0.2
you can do this too with animation, its very simple
$('html, body').animate({
scrollTop: $('footer').offset().top
//scrollTop: $('#your-id').offset().top
//scrollTop: $('.your-class').offset().top
}, 'slow');
hope helps, thank you
You can use this function wherever you need to call it:
function scroll_to(div){
if (div.scrollTop < div.scrollHeight - div.clientHeight)
div.scrollTop += 10; // move down
}
Sometimes the page extends on scroll to buttom (for example in social networks), to scroll down to the end (ultimate buttom of the page) I use this script:
var scrollInterval = setInterval(function() {
document.documentElement.scrollTop = document.documentElement.scrollHeight;
}, 50);
And if you are in browser's javascript console, it might be useful to be able to stop the scrolling, so add:
var stopScroll = function() { clearInterval(scrollInterval); };
And then use stopScroll();
.
If you need to scroll to particular element, use:
var element = document.querySelector(".element-selector");
element.scrollIntoView();
Or universal script for autoscrolling to specific element (or stop page scrolling interval):
var notChangedStepsCount = 0;
var scrollInterval = setInterval(function() {
var element = document.querySelector(".element-selector");
if (element) {
// element found
clearInterval(scrollInterval);
element.scrollIntoView();
} else if((document.documentElement.scrollTop + window.innerHeight) != document.documentElement.scrollHeight) {
// no element -> scrolling
notChangedStepsCount = 0;
document.documentElement.scrollTop = document.documentElement.scrollHeight;
} else if (notChangedStepsCount > 20) {
// no more space to scroll
clearInterval(scrollInterval);
} else {
// waiting for possible extension (autoload) of the page
notChangedStepsCount++;
}
}, 50);
You may try Gentle Anchors a nice javascript plugin.
Example:
function SomeFunction() {
// your code
// Pass an id attribute to scroll to. The # is required
Gentle_Anchors.Setup('#destination');
// maybe some more code
}
Compatibility Tested on:
one liner to smooth scroll to the bottom
window.scrollTo({ left: 0, top: document.body.scrollHeight, behavior: "smooth" });
To scroll up simply set top
to 0
Here's my solution:
//**** scroll to bottom if at bottom
function scrollbottom() {
if (typeof(scr1)!='undefined') clearTimeout(scr1)
var scrollTop = (document.documentElement && document.documentElement.scrollTop) || document.body.scrollTop;
var scrollHeight = (document.documentElement && document.documentElement.scrollHeight) || document.body.scrollHeight;
if((scrollTop + window.innerHeight) >= scrollHeight-50) window.scrollTo(0,scrollHeight+50)
scr1=setTimeout(function(){scrollbottom()},200)
}
scr1=setTimeout(function(){scrollbottom()},200)
Late to the party, but here's some simple javascript-only code to scroll any element to the bottom:
function scrollToBottom(e) {
e.scrollTop = e.scrollHeight - e.getBoundingClientRect().height;
}
You can attach any id
to reference attribute href
of link element:
<a href="#myLink" id="myLink">
Click me
</a>
In the example above when user clicks Click me
at the bottom of page, navigation navigates to Click me
itself.
For Scroll down in Selenium use below code:
Till the bottom drop down, scroll till the height of the page. Use the below javascript code that would work fine in both, JavaScript and React.
JavascriptExecutor jse = (JavascriptExecutor) driver; // (driver is your browser webdriver object)
jse.executeScript("window.scrollBy(0,document.body.scrollHeight || document.documentElement.scrollHeight)", "");
So many answers trying to calculate the height of the document. But it wasn't calculating correctly for me. However, both of these worked:
jquery
$('html,body').animate({scrollTop: 9999});
or just js
window.scrollTo(0,9999);
A very simple way
Call this function whenever you want to scroll down.
function scrollDown() {
document.getElementById('scroll').scrollTop = document.getElementById('scroll').scrollHeight
}
ul{
height: 100px;
width: 200px;
overflow-y: scroll;
border: 1px solid #000;
}
<ul id='scroll'>
<li>Top Here</li>
<li>Something Here</li>
<li>Something Here</li>
<li>Something Here</li>
<li>Something Here</li>
<li>Something Here</li>
<li>Something Here</li>
<li>Something Here</li>
<li>Something Here</li>
<li>Something Here</li>
<li>Bottom Here</li>
<li style="color: red">Bottom Here</li>
</ul>
<br />
<button onclick='scrollDown()'>Scroll Down</button>
getDocHeight: function() {
var D = document;
return Math.max(
D.body.scrollHeight,
D.documentElement.scrollHeight,
D.body.offsetHeight,
D.documentElement.offsetHeight,
D.body.clientHeight,
D.documentElement.clientHeight
);
}
document.body.scrollTop = document.documentElement.scrollTop = this.getDocHeight();
This will guaranteed scroll to the bottom
Head Codes
<script src="http://code.jquery.com/jquery-1.8.1.min.js"></script>
<script language="javascript" type="text/javascript">
function scrollToBottom() {
$('#html, body').scrollTop($('#html, body')[0].scrollHeight);
}
</script>
Body code
<a href="javascript:void(0);" onmouseover="scrollToBottom();" title="Scroll to Bottom">▼ Bottom ▼</a>
A picture is worth a thousand words:
The key is:
document.documentElement.scrollTo({
left: 0,
top: document.documentElement.scrollHeight - document.documentElement.clientHeight,
behavior: 'smooth'
});
It is using document.documentElement
, which is the <html>
element. It is just like using window
, but it is just my personal preference to do it this way, because if it is not the whole page but a container, it works just like this except you'd change document.body
and document.documentElement
to document.querySelector("#container-id")
.
let cLines = 0;
let timerID = setInterval(function() {
let elSomeContent = document.createElement("div");
if (++cLines > 33) {
clearInterval(timerID);
elSomeContent.innerText = "That's all folks!";
} else {
elSomeContent.innerText = new Date().toLocaleDateString("en", {
dateStyle: "long",
timeStyle: "medium"
});
}
document.body.appendChild(elSomeContent);
document.documentElement.scrollTo({
left: 0,
top: document.documentElement.scrollHeight - document.documentElement.clientHeight,
behavior: 'smooth'
});
}, 1000);
body {
font: 27px Arial, sans-serif;
background: #ffc;
color: #333;
}
You can compare the difference if there is no scrollTo()
:
let cLines = 0;
let timerID = setInterval(function() {
let elSomeContent = document.createElement("div");
if (++cLines > 33) {
clearInterval(timerID);
elSomeContent.innerText = "That's all folks!";
} else {
elSomeContent.innerText = new Date().toLocaleDateString("en", {
dateStyle: "long",
timeStyle: "medium"
});
}
document.body.appendChild(elSomeContent);
}, 1000);
body {
font: 27px Arial, sans-serif;
background: #ffc;
color: #333;
}
window.scrollTo(0,1e10);
always works.
1e10 is a big number. so its always the end of the page.
If any one searching for Angular
you just need to scroll down add this to your div
#scrollMe [scrollTop]="scrollMe.scrollHeight"
<div class="my-list" #scrollMe [scrollTop]="scrollMe.scrollHeight">
</div>
I have an Angular app with dynamic content and I tried several of the above answers with not much success. I adapted @Konard's answer and got it working in plain JS for my scenario:
HTML
<div id="app">
<button onClick="scrollToBottom()">Scroll to Bottom</button>
<div class="row">
<div class="col-md-4">
<br>
<h4>Details for Customer 1</h4>
<hr>
<!-- sequence Id -->
<div class="form-group">
<input type="text" class="form-control" placeholder="ID">
</div>
<!-- name -->
<div class="form-group">
<input type="text" class="form-control" placeholder="Name">
</div>
<!-- description -->
<div class="form-group">
<textarea type="text" style="min-height: 100px" placeholder="Description" ></textarea>
</div>
<!-- address -->
<div class="form-group">
<input type="text" class="form-control" placeholder="Address">
</div>
<!-- postcode -->
<div class="form-group">
<input type="text" class="form-control" placeholder="Postcode">
</div>
<!-- Image -->
<div class="form-group">
<img style="width: 100%; height: 300px;">
<div class="custom-file mt-3">

</div>
</div>
<!-- Delete button -->
