嵌套的javascript onmousedown事件

<script type="text/javascript">

function bar(evt) {
  // Your stuff here
  if (typeof evt.stopPropagation != "undefined") {
    evt.stopPropagation();
  } else {
    evt.cancelBubble = true;
  }
}

</script>

<div id="parent" onmousedown="foo();">
  <div id="child1"> </div>
  <div id="child2"> </div>
  <div id="child3" onmousedown="bar(event);"> </div>
</div>

在HTML中:

<div id="parent" onmousedown="foo();">
  <div id="child1"> </div>
  <div id="child2"> </div>
  <div id="child3" onmousedown="bar(event);"> </div>
</div>

在javascript中

function bar(event)
{
    // usual bar stuff
    event.stopPropagation();
}
