Can't capture click event on hidden input dropdown

I'm using a dropdown that's using a combination of a hidden checkbox and :focus to show the options.

I can't figure out how to bind a click event to it though.

<p><i>To show/hide menu, I'm using :focus instead of checkbox so when you click somewhere else then menu will be hidden :).</i></p>

<div class="dropdown">
<input class="dropdown-toggle" type="text">
<div class="dropdown-text">Account</div>
<ul class="dropdown-content">
<li><a href="#">Settings</a></li>
<li><a href="#">Projects</a></li>
<li><a href="#">Log out</a></li>
</ul>
</div>





Here is a few different ways I've tried to capture the event.

$('.dropdown').click(function(){
alert('yo');
});

$('.dropdown-toggle').click(function(){
alert('yo');
});

$('.dropdown').change(function(){
alert('yo');
});


Sadly, no yo. What can I do?

Answer

If you're using focus to build the dropdown, perhaps triggering the event on that same focus would be an adequate solution:

$(document).ready(function() {

  $(".dropdown-toggle").focus(function() {
    alert("Yo!");
  });

});
