Definition and usage
When the element is double-clicked , the dblclick event occurs. A click occurs when the mouse pointer is over an element and the left mouse button is pressed and released. If two clicks occur within a short period of time, it is a double click event. The dblclick() method triggers the dblclick event, or specifies a function to run when the dblclick event occurs. Tip: Problems may arise if dblclick and click events are applied to the same element.

<html>
<head>
<script type="text/javascript" src="/jquery/jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
  $("button").dblclick(function(){
    $("p").slideToggle();
  });
  $("p").click(function(){
    $("button").dblclick();
  });
});
</script>
</head>
<body>
<button>请双击这里</button>
<p>点击本段落会触发上面这个按钮的 dblclick 事件。</p>
