将处理程序缓存到变量。然后使用该引用绑定和解除绑定。

Cache the handler to a variable. Then bind and unbind using that reference.

而不是将您的click事件内联绑定：

Instead of binding your click event inline:

$('#test').bind('click', function(){
    alert('hi!');
});

将函数声明为变量：

var clickHandle = function(){
    alert('hi!');
};

然后使用变量名称绑定：

And then bind using the variable name:

$('#test').bind('click', clickHandle);

然后你可以取消绑定特定的点击处理程序：

Then you can unbind the specific click handler:

$('#test').unbind('click', clickHandle);

然后你仍然可以重新绑定相同的功能：

Then you can still re-bind the same function:

$('#test').bind('click', clickHandle);

快速查看来源。事件绑定到contextmenu，而不是单击。

Took a quick look at the source. The event is bound to contextmenu, not click.

您可以通过元素的data.events属性访问该函数（类似于j3frea所说的）。请查看此小提琴示例以获得完整分辨率。

You can access the function through the element's data.events property (similar to what j3frea was saying). Have a look at this fiddle example for a full resolution.

基本上你可以这样做：

var cachedHandler = null;
// disable
cachedHandler = $('#demo2').data('events').contextmenu[0].handler;
$('#demo2').unbind('contextmenu', cachedHandler);
// enable
$('#demo2').bind('contextmenu', cachedHandler);
