使用IE双击 [英] double click using IE

问题描述

我在IE中发现了双击问题.

I have discovered a double-click problem in IE.

以下是我的HTML:

<div id="test">Hello World!</div>

还有我的jQuery:

And my jQuery:

$('#test').bind('dblclick', function (event) {
    event.stopPropagation();
    $(this).css({'background-color': 'red'});
});

在IE中，请执行以下操作:

In IE, do the following:

1. 在DIV之外，鼠标向下→鼠标向上→鼠标向下→保持鼠标向下.
2. 然后，在按住鼠标的同时，将鼠标移到DIV中并向上移动鼠标.

1. Outside the DIV, mouse down → mouse up → mouse down → HOLD the mouse down.
2. Then, with the mouse held down, move the mouse into the DIV and mouse up.

DIV变为红色，就像双击事件起源于DIV.

The DIV turns red, as if the double-click event originated in the DIV.

似乎在IE中，双击时都会触发双击事件:

It seems that in IE the double-click event is fired both when the double-click：

1. DIV中的开始和结束
2. 在DIV外部开始，在DIV内部结束.

但是在FF/Chrome中，只有双击DIV中的STARTS和ENDS才会触发该事件.

Yet in FF/Chrome the event is fired only when the double click STARTS and ENDS inside the DIV.

对此的官方解释是什么?以及如何使IE双击的行为类似于FF/Chrome双击?

What is the official explanation for this? And how can I make IE double-clicks behave like FF/Chrome double-clicks?

推荐答案

(on)dblclick事件是本地javascript事件，而不是jquery事件

Dblclick事件在各浏览器中不一致，请参阅此票证已使用3年了，但仍在某种程度上有效: http ://bugs.jquery.com/ticket/7876 甚至现在IE10中的顺序与FF/Chrome/Safari相同，但正如您所指出的那样，仍然存在一些错误.

Dblclick event is not consistent across browsers, see this ticket 3 years old but still valid in some way: http://bugs.jquery.com/ticket/7876 even now sequence in IE10 is the same as FF/Chrome/Safari but as you noted it, there are still some bugs.

作为解决方法，您可以使用以下代码段代替dblclick事件:

As a workaround, you could use this snippet instead of dblclick event:

使用自定义dblclick的演示

$('#test').on('click', function(event){
    var t = this;
    if (!t.clicks) t.clicks = 0;
         ++t.clicks;
         if (t.clicks === 2) {
             t.clicks = 0;
             //here the kind of dclclick is fired ...
             $(t).css({'background-color' : "red"});
         }
         setTimeout(function () {
             t.clicks = 0
         }, 500);//duration value can be change depending of your wishes

});

另一种解决方法可能是在mousedown/mouseenter/mouseleave(悬停)处理程序上绑定/解除绑定dblclick事件，例如:

An other workaround could be to bind/unbind dblclick event on mousedown/mouseenter/mouseleave (hover) handlers, like that:

DEMO，具有mousedown/mouseenter/mouseleave

$('#test').hover(function () {
    $(this).on('mousedown.cust', function () {
        $(this).on('dblclick.cust', function () {
            $(this).css({
                'background-color': "red"
            });
        });
    });
}, function () {
    $(this).off('mousedown.cust dblclick.cust');
});
