Question

window.opener.document.all["LabEor"].style.visibility="hidden";

Answer 1

Visible 是 .net 里服务器控件的属性, 不是DHTML里的属性, 所以JS是调用不到的.
还是在客户端把这个控件隐藏掉算了.
window.opener.document.all["LabEor"].style.display = "none";

Answer 2

b.aspx因为用服务器控件,设置其为Visible="true"<form id="frm" runat="server">
<table>
<asp:textbox id="txCode" Runat="server"></asp:textbox>
<asp:Label id="LabEor" runat="server" ForeColor="Red" Visible="true">aaa</asp:Label>
</table>
</form>
<script>
//用脚本来隐藏.
document.all.LabEor.style.visibility="hidden";
</script>
<input type="button" onclick="window.open('a.aspx')" value="Open"/>
a.aspx<script language="javascript">
             function SelectBus(Code)
                 {
                      //var openerFormID="frm";    
                          
                      window.opener.document.all["txCode"].value=Code;
                      window.opener.document.all["LabEor"].style.visibility="visible";    
                      window.close();
                 }
SelectBus('test');
</script>
