event.srcElement在火狐下的兼容问题——ie用event.srcElement,火狐用event.target

<span style="font-family:Microsoft YaHei;font-size:12px;">event.srcElement : 可以捕获当前事件作用的对象
<a href="#" onclick="test(event)"><img src="images/index_33-1.jpg" border="0"/></a>

<script language="javascript" type="text/javascript">
function test(event) {
event = event? event: window.event
var obj = event.srcElement ? event.srcElement:event.target;
if ( document.all) {
obj.click();
} else {
var evt = document.createEvent("MouseEvents");
evt.initEvent("click", true, true);
obj.dispatchEvent(evt);
}
}
</script></span>
