In jquery click and dblclick are both click events, but in dblclick event is a repeated click on the click event, so if we do it at the same time, it will conflict, as follows Let's look at the analysis.

In the double-click event (dblclick), among the two click events (click) triggered, the first click event (click) will be blocked, but the second one will not.

<script type="text/javascript">
$(document).ready(function(){
  $("button").click(function(){
    $("p").slideToggle();
  });
});
</script>
</head>
<body>
<p>这是一个段落。</p>
<button>切换</button>
</body>

That is to say, a double-click event (dblclick) will return a click event (click) result and a double-click event (dblclick) result. Instead of the result of a double-click event (dblclick) and the result of two click events (click).

dblclick()When an 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.

<script type="text/javascript">
$(document).ready(function(){
  $("button").dblclick(function(){
    $("p").slideToggle();
  });
});
</script>
</head>
<body>
<p>这是一个段落。</p>
<button>请双击此处</button>
</body>

In this case, just eliminate the extra click event (click) and the problem will be solved.

var timer = null; 
$(&#39;button&#39;).live(&#39;click&#39;, function(event){ 
    timer && clearTimeout(timer); 
    timer = setTimeout(function(){ 
        console.log(event.type); 
    },300); 
}).live(&#39;dblclick&#39;, function(event){ 
    timer && clearTimeout(timer); 
    console.log(event.type); 
});
