Firefox 中的 Firefox 5 调度事件

发布于 2024-11-17 00:06:33 字数 397 浏览 4 评论 0原文

我有一些代码使用 dispatchEvent 来模拟点击，同样的代码在 Chrome 中工作正常，但在 Firefox 中不起作用。代码如下：

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

我单击一个加载另一个页面的链接，该页面在 Chrome 中加载正常，但当我在 Firebug 中运行此代码时，甚至当我将其作为书签执行时，Firefox 绝对不会执行任何操作。我还通过设置 MDC 文档中显示的所有选项来尝试长形式的事件初始化，但这没有任何作用。我到底做错了什么？

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);

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?

由于您的事件看起来是鼠标事件，因此您可能会尝试使用鼠标事件，如下例所示：

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;
        }

请参阅 W3C 鼠标事件类型

我还用法语写了一篇关于触发 DOM 事件 ;我想翻译起来很容易。

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;
        }

See W3C Mouse event types

I also wrote a tutorial in French language about firing DOM events ; I guess it's easy to get it translated.
