使用适用于 IE 的 Javascript 模拟单击​​链接 [英] Emulate clicking a link with Javascript that works with IE

问题描述

我想让 java 脚本点击页面上的链接..我在网上找到了一些建议添加这样的功能的东西:

I want to have java script clicking a link on the page..I found something on the net that suggests adding a function like this:

function fireEvent(obj,evt){

    var fireOnThis = obj;
    if( document.createEvent ) {
      var evObj = document.createEvent('MouseEvents');
      evObj.initEvent( evt, true, false );
      fireOnThis.dispatchEvent(evObj);
    } else if( document.createEventObject ) {
      fireOnThis.fireEvent('on'+evt);
    }
}

然后使用:

fireEvent(document.getElementById('edit_client_link'),'click');

这对于 FF 似乎工作正常，但对于 IE 则不起作用！

This seems to work fine for FF but with IE it doesn't work!

有什么想法吗?

推荐答案

我认为你仍然需要调用 document.createEventObject —— 你只是检查了它在那里.未经测试的代码如下，但基于 docs应该工作.

I think you still need to call document.createEventObject -- you only checked that it's there. Untested code follows, but based on the docs it should work.

function fireEvent(obj,evt){

    var fireOnThis = obj;
    if( document.createEvent ) {
      var evObj = document.createEvent('MouseEvents');
      evObj.initEvent( evt, true, false );
      fireOnThis.dispatchEvent( evObj );

    } else if( document.createEventObject ) {
      var evObj = document.createEventObject();
      fireOnThis.fireEvent( 'on' + evt, evObj );
    }
}
