解决了火狐下无法触发click事件的问题

<script language="javascript">
    function test2(name)
    {
        if(document.all)
        {
            document.getElementById(name).click();
        }
        else
        {
            var evt = document.createEvent("MouseEvents");
            evt.initEvent("click", true, true);
            document.getElementById(name).dispatchEvent(evt);
        }
    }
</script>

<a href="#" id="a3" onclick="location.href = 'http://www.baidu.com';">baidu</a>
<input type="button" value="clck" onclick="test2('a3');"/>
