jQuery click event on link won't get catched in vaniila JS


I am using the following Vanilla binding in order to simulate the jQuery delegation event:

document.addEventListener('click', function(e) {
    console.log("some element was clicked");
    console.log(e.target);

    //here's where I would filter by target
});

It is all working fine except when I try to trigger with jQuery a click event on a link element <a href="#">. Then it won't work at all. The vanilla click event handler won't be triggered.

Reproduction working on <b> element

$('button').click(function() {
    $('ul').append('<li><b>New</b></li>');
});

document.addEventListener('click', function(e) {
    console.log("some element was clicked");
    console.log(e.target);
});

$(document).on('keydown', function(){
    console.warn("-------Trigger--------")
	$('li').find('b').trigger('click');
});
div{
    background: yellow;
    padding:10px 20px;
    border: 1px solid #ccc;
    margin: 10px 0;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button>Add element</button>
<span id="trigger">Trigger</span>
<div>
 Just focus the white panel and press any key. That will trigger the jQuery.click() event as you can see in the code.
</div>
<ul>
    <li>Old element</li>
    <li>Old element</li>
    <li><b>Old element</b></li>
</ul>

Instead, if I replace the link element for a bold one <b> it works as expected. What's going on? Reproduction not working on <a> element

$('button').click(function() {
    $('ul').append('<li><a href="#">New</a></li>');
});

document.addEventListener('click', function(e) {
    console.log("some element was clicked");
    console.log(e.target);
});

$(document).on('keydown', function(){
    console.warn("-------Trigger--------")
	$('li').find('a').trigger('click');
});
div{
    background: yellow;
    padding:10px 20px;
    border: 1px solid #ccc;
    margin: 10px 0;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button>Add element</button>
<span id="trigger">Trigger</span>
<div>
 Just focus the white panel and press any key. That will trigger the jQuery.click() event as you can see in the code.
</div>
<ul>
    <li>Old element</li>
    <li>Old element</li>
    <li><a href="#">Old element</a></li>
</ul>

And no, I do not want to use [0] like this:

$('li').find('a')[0].click();

I want it to fire normally:

$('li').find('a').click();

Solution

  • Unfortunately, you cannot trigger native click handlers in jQuery on links, it is disabled in the source and a comment says "For cross-browser consistency, don't fire native .click() on links".

    So, you will either have to bind the document click handler using jQuery $(document).on("click") or call the nodes clickHandler directly $('li').find('a')[0].click();
