use
用
onclientclick="javascript:return YourFunction();"
<script>
function YourFunction() {
//Do your stuff
return true;
}
</script>
If you return true your asp.new onclick event will be called.. If you return false it wont be called..
如果你返回 true 你的 asp.new onclick 事件将被调用.. 如果你返回 false 它不会被调用..

as you call it, but prevent the post back by return false on
正如你所说，但通过 return false on 阻止回帖
OnClientClick="myClosure();return false;"
I do not know nether understand the rest of your logic, but this is your issue right now.
我不知道你是否理解你的其余逻辑，但这是你现在的问题。
