Firefox 5 dispatchEvent不能正常工作 [英] Firefox 5 dispatchEvent not working

问题描述

我有一些使用 dispatchEvent 来模拟点击的代码，在Chrome中相同的代码工作正常，但在Firefox中不起作用。以下是代码：

I have some code that uses dispatchEvent to simulate clicks and the same exact code works fine in Chrome but doesn't work in Firefox. Here's the code:

var evt = document.createEvent("MouseEvents");
evt.initEvent("click",true,true);
jQuery("a:contains(Next)")[0].dispatchEvent(evt);

我点击一个加载另一个页面的链接，页面在Chrome中正常加载，但Firefox当我在Firebug中运行这个代码，甚至当我将它作为一个书签执行时，绝对没有任何东西。我也尝试了通过设置MDC文档中显示的所有选项来初始化事件的长形式，但是这并没有做任何事情。到底什么是我在这里做错了？

I'm clicking on a link that loads another page and the page loads fine in Chrome but Firefox does absolutely nothing when I run this code in Firebug or even when I execute it as a bookmarklet. I've also tried the long form of event initializing by setting all the options as shown on the MDC docs but that doesn't do anything. What exactly am I doing wrong here?

推荐答案

由于你的事件看起来像一个鼠标事件，你可以尝试使用鼠标事件，就像这个例子：

As your event looks to be a mouse event, you may rather try using a mouse event, like this example :

var oEvt = (document.createEvent)? document.createEvent('MouseEvents') : document.createEventObject();    
       // W3C
        if (oEvt.initMouseEvent) 
            oEvt.initMouseEvent(
                /* type*/            'mouseup',
                /* bubble*/            true,
                /* cancel*/            true,
                /* AbstractView*/     window,
                /* detail */        10,
                /* screenX */        20,
                /* screenY */        30, 
                /* clientX */        40,
                /* clientY */        50,
                /* ctrlKey */        false,
                /* altKey */        false,
                /* shiftKey */        true,
                /* metaKey */        false,
                /* button */        0,
                /* relatedTarget*/    null ) ;
        // MSIE
        else {
                var oEvt = document.createEventObject(); 
                oEvt.detail = 10;
                oEvt.screenX = 20;
                oEvt.screenY = 30;
                oEvt.clientX = 40;
                oEvt.clientY = 50;
                oEvt.ctrlKey = false;
                oEvt.altKey = false;
                oEvt.shiftKey = true;
                oEvt.metaKey = false;
                oEvt.button = 0;
                oEvt.relatedTarget = null;
        }
