是否有内置的方式在JavaScript中本地生成自定义事件? [英] Is there a built in way to make custom events in JavaScript natively?
问题描述
我刚才玩JavaScript时,我无法创建自己的事件让我感到恼火。
I was playing around with JavaScript a little while ago, and it irritated me that I couldn't create my own event.
我看过这个框架了内置(jQuery,MooTools,Prototype.Dojo并不奇怪,因为它似乎做了所有事情和你的洗衣店)而且我实际上构建了自己的系统来创建和解雇自定义事件。
I've seen Framework's with this built in (jQuery, MooTools, Prototype. Dojo doesn't which is weird because it seems to do everything and your laundry) and I actually built my own system for creating and firing custom events.
感觉应该有一种本地的方式来做到这一点。有没有人知道怎么做/如果你可以?
It just feels like there should be a native way to do it. Does anyone know how to do this/if you even can?
推荐答案
var dragEvent = document.createEvent("Event");
dragEvent.initEvent("dragged", true, true);
el.dispatchEvent(dragEvent);
有关官方规格,请参阅 DOM Level 2 Events 。另请参见 createEvent()
, initEvent()
/ initMouseEvent()
/ initUIEvent()
和 dispatchEvent()
at MDC。
For official specs, see DOM Level 2 Events. See also createEvent()
, initEvent()
/ initMouseEvent()
/ initUIEvent()
, and dispatchEvent()
at MDC.
我使用此技术为此示例页面。
