jQuery Click fires twice when clicking on label

Try adding:

evt.stopPropagation();
evt.preventDefault();

to the .bind() or .click(), whichever you're seeing. Also, add the parameter evt to the function, like function(evt) {...

Bind the click event to the input rather than the label. When the label is clicked - the event will still occur because, as Dustin mentioned, a click on the label triggers a click on the input. This will allow the label to hold its normal functionality.

$('input').click();

Instead of

$('label').click();

If you're trying to use an outer container as a click element you can also let the events bubble naturally and test for the expected element in your click handler. This scenario is useful if you're trying to style a unique click zone for a form.

<form>
<div id="outer">
    <label for="mycheckbox">My Checkbox</label>
    <input type="checkbox" name="mycheckbox" id="mycheckbox" value="on"/>
</div>
</form>
<script>
$('#outer').on('click', function(e){
    // this fires for #outer, label, and input
    if (e.target.tagName == 'INPUT'){
        // only interested in input
        console.log(this);
    }
});
</script>

I tried adding the solution above by adding:

evt.stopPropagation();
evt.preventDefault();

but didn't work. However adding this:

evt.stopImmediatePropagation();

solved the problem! :)
