How to determine if child was clicked in Jquery

问题

Is there a ways in jQuery to tell which child was clicked if the onclick event was binded to the parent?

For instance:

  $('#daddy').click(function () {
    // if($("#son").isClicked()){return true;}
    //return false;
  });

and the markup looks like:

<div id="daddy">
  <span id="son"></span>
  <span id="daughter"></span>
</div>

回答1:

The event handler you pass to click will receive an event object as its first argument. The target of the event (i.e. the element that initiated the event) will be specified there.

Here's an example from the jQuery documentation:

<!DOCTYPE html>
<html>
<head>
  <style>
span, strong, p { 
  padding: 8px; display: block; border: 1px solid #999;  }
    </style>
  <script src="http://code.jquery.com/jquery-latest.js"></script>
</head>
<body>

<div id="log"></div>
<div>
  <p>
    <strong><span>click</span></strong>
  </p>
</div>
<script>

$("body").click(function(event) {
  $("#log").html("clicked: " + event.target.nodeName);
});

</script>  
</body>
</html>

You can use the event.target to determine what was clicked:

  $('#daddy').click(function (e) {
      alert(e.target.id); // The id of the clicked element
  });

Here's a simple example.

This should be a different perspective at least:

$('#parent').on("click", function(evt) {
        evt.stopPropagation();
        if($.inArray(evt.currentTarget, $(this).children())){
            console.log(evt.currentTarget);
        }
});

check this demo out

$(function() {
    $('#parent').delegate('a', 'click', function(evt) {
        debugger;
        evt.stopPropagation();
        alert($(evt.currentTarget).attr('id'));
    });
});

回答5:

use event.target to get the really clicked node:

$('#daddy span').on('click',function(event){
    if(event.target.nodeName=='BUTTON'){//Was clicked a button
        ....
    }
    if(event.target.id=='id'){//Was clicked #id
        ....
    }
    ...
});

Try this for an alternative

$('#daddy span').click(function () {
    var clicked = $(this).attr('id');
    if(clicked == "son"){
        return true;
    }
    return false;
});
