如何检查鼠标单击事件是模拟的还是本地的？ （非jQuery方式） [英] How to check if mouse click event is simulated or is native? (non-jQuery way)

问题描述

使用jQuery很容易。使用纯JavaScript并非如此，至少，要找到如何做到这一点并不容易。 if（event.clientX&& event.clientY）{...} 进行某种检测，但不是100％准确。

With jQuery it's easy. With pure JavaScript isn't, at least it isn't easy to find out how. if (event.clientX && event.clientY) { ... } gives kind-of detection, but it's not 100% accurate.

推荐答案

有是的一种方法，但是IMHO颇具争议。尝试以下操作：

There is a way, but it's quite controversial IMHO. Try this:

HTMLElement.prototype.dispatchEvent = (function(dispev) {
    return function(event) {
        // Do your stuff
        dispev.call(this, event);
    };
})(HTMLElement.prototype.dispatchEvent);

借助此功能，您可以捕获对 dispatchEvent的每次调用调度以编程方式生成的事件时。当然，这会放慢调度的速度，但是除非您要尝试触发许多事件，否则这不是问题。

With this, you're able to catch every call to dispatchEvent when a programmatically generated event is dispatched. Of course, this would slow down a bit the dispatching, but shouldn't be a problem unless you're trying to fire a lot of events.

在IE8中，您必须替换 Element.prototype.fireEvent ，而在IE7及更低版本中，则无法执行任何操作。

In IE8 you must replace Element.prototype.fireEvent instead, while in IE7 and lower it's just not possible to do anything about it.
