jQuery on 'double click' event (dblclick for mobile)

You can bind multiple event listeners on the element and use jQuery's tap event for the touch devices.

$( ".target" ).on({
  dbclick: function() {
    //do stuff
  }, touch: function() {
    //do the same stuff
  }
});

Add this to your index.html

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=0"/>

I found the mobile zoom function would throw off Jquery's dblclick. Basically it says your viewport wont change effectively shutting off the zoom. This works for me on my Nexus 5 running Chrome.

I ended up building a custom double click function that will work on both mobile and desktop:

var touchtime = 0;
$(".target").on("click", function() {
    if (touchtime == 0) {
        // set first click
        touchtime = new Date().getTime();
    } else {
        // compare first click to this click and see if they occurred within double click threshold
        if (((new Date().getTime()) - touchtime) < 800) {
            // double click occurred
            alert("double clicked");
            touchtime = 0;
        } else {
            // not a double click so set as a new first click
            touchtime = new Date().getTime();
        }
    }
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<div class="target">Double click me</div>

Alternatively, here is the JSfiddle Demo.

I know the question has been answered but thought it would be worth putting the solution I use all the time, cheers:

    var doubleClicked = false;
    $('.target').on('click', function() {   
        if (doubleClicked) {
            //do what you want to do on double click here
        }
        doubleClicked = true;
        setTimeout(() => {
            doubleClicked = false;
        }, 300);
    });
