使用 Prototype 触发事件 [英] Trigger an event with Prototype

问题描述

有谁知道在 Prototype 中触发事件的方法，就像使用 jQuery 的触发函数一样?

Does anybody know of a method to trigger an event in Prototype, as you can with jQuery's trigger function?

我已经使用observe 方法绑定了一个事件侦听器，但我还希望能够以编程方式触发该事件.

I have bound an event listener using the observe method, but I would also like to be able to fire the event programatically.

推荐答案

event.simulate.js 满足您的需求.

event.simulate.js fits your needs.

我已经多次使用它，它的作用就像一个魅力.它允许您手动触发原生事件，例如单击或悬停，如下所示:

I've used this several times and it works like a charm. It allows you to manually trigger native events, such as click or hover like so:

$('foo').simulate('click');

这样做的好处是所有附加的事件处理程序仍将被执行，就像您自己单击元素一样.

The great thing about this is that all attached event handlers will still be executed, just as if you would have clicked the element yourself.

对于自定义事件，您可以使用标准原型方法Event.fire().

For custom events you can use the standard prototype method Event.fire().
