Stop setInterval

I want to stop this interval in the error handler from running repeatedly. Is that possible, and if so, how?

// example code
$(document).on('ready',function(){
    setInterval(updateDiv,3000);
});

function updateDiv(){
    $.ajax({
        url: 'getContent.php',
        success: function(data){
            $('.square').html(data);
        },
        error: function(){
            $.playSound('oneday.wav');
            $('.square').html('<span style="color:red">Connection problems</span>');
            // I want to stop it here
        }
    });
}

You need to set the return value of setInterval to a variable within the scope of the click handler, then use clearInterval() like this:

var interval = null;
$(document).on('ready',function(){
    interval = setInterval(updateDiv,3000);
});

function updateDiv(){
    $.ajax({
        url: 'getContent.php',
        success: function(data){
            $('.square').html(data);
        },
        error: function(){
            clearInterval(interval); // stop the interval
            $.playSound('oneday.wav');
            $('.square').html('<span style="color:red">Connection problems</span>');
        }
    });
}
Answer

Use a variable and call clearInterval to stop it.

var interval;

$(document).on('ready',function()
  interval = setInterval(updateDiv,3000);
  });

  function updateDiv(){
    $.ajax({
      url: 'getContent.php',
      success: function(data){
        $('.square').html(data);
      },
      error: function(){
        $.playSound('oneday.wav');
        $('.square').html('<span style="color:red">Connection problems</span>');
        // I want to stop it here
        clearInterval(interval);
      }
    });
  }
Answer

You have to assign the returned value of the setInterval function to a variable

var interval;
$(document).on('ready',function(){
    interval = setInterval(updateDiv,3000);
});

and then use clearInterval(interval) to clear it again.

Answer

USE this i hope help you

var interval;

function updateDiv(){
    $.ajax({
        url: 'getContent.php',
        success: function(data){
            $('.square').html(data);
        },
        error: function(){
            /* clearInterval(interval); */
            stopinterval(); // stop the interval
            $.playSound('oneday.wav');
            $('.square').html('<span style="color:red">Connection problems</span>');
        }
    });
}

function playinterval(){
  updateDiv(); 
  interval = setInterval(function(){updateDiv();},3000); 
  return false;
}

function stopinterval(){
  clearInterval(interval); 
  return false;
}

$(document)
.on('ready',playinterval)
.on({click:playinterval},"#playinterval")
.on({click:stopinterval},"#stopinterval");
Answer

we can easily stop the set interval by calling clear interval

var count = 0 , i = 5;
var vary = function intervalFunc() {
  count++;
      console.log(count);
    console.log('hello boy');  
    if (count == 10) {
      clearInterval(this);
    }
}

  setInterval(vary, 1500);

var flasher_icon = function (obj) {
    var classToToggle = obj.classToToggle;
    var elem = obj.targetElem;
    var oneTime = obj.speed;
    var halfFlash = oneTime / 2;
    var totalTime = obj.flashingTimes * oneTime;

    var interval = setInterval(function(){
        elem.addClass(classToToggle);
        setTimeout(function() {
            elem.removeClass(classToToggle);
        }, halfFlash);
    }, oneTime);

    setTimeout(function() {
        clearInterval(interval);
    }, totalTime);
};

flasher_icon({
    targetElem: $('#icon-step-1-v1'),
    flashingTimes: 3,
    classToToggle: 'flasher_icon',
    speed: 500
});
