IE和火狐中模仿Click事件及提交到新窗口总结(asp.net)

<a href=//www.VeVB.COm target="_blank" id="aa">ok</a>
<script>
var comment = document.getElementById('aa');
if (document.all) {
comment.click();
} else {　//火狐，如果<a>中没有定义onclick事件，则本段对火狐不起作用
var ev = document.createEvent("MouseEvents");
ev.initEvent("click", true, true);
document.getElementById("aa").dispatchEvent(ev);
}

</script>

<form action="/shopping/index" method="post" id="processorder" target="_blank" onsubmit="return checkOrder()">

</form>
