js 弹出层，使用UpdatePanel来控制，如何关闭和相应登录的用户?
使用了下边的js弹出层代码后，因为当相应弹出层，不管用户是否登录都会关闭z-index：2，3所以我在弹出层上使用了UpdatePanel局部更新，控制弹出层，
但是现在的问题：不知道如何关闭弹出层，Session存储用户，登录后无法加载进去，请高手指点
<script language="javascript">
function locking(){
document.all.zzjs_net.style.display="block";
document.all.zzjs_net.style.width=document.body.clientWidth;
document.all.zzjs_net.style.height=document.body.clientHeight;
document.all.www_zzjs_net.style.display='block';
document.getElementById("<%=textEmial.ClientID %>").value="";
}
function Lock_CheckForm(theForm){
document.all.zzjs_net.style.display='none';document.all.www_zzjs_net.style.display='none';
document.getElementById("<%=textEmial.ClientID %>").value="21";
return false;
}
