.NET之后台用户权限管理实现

//利用js添加逗号和竖线 ，通过hidden传值

script language="javascript" type="text/javascript">

function getcheck() {
var inputs = document.getElementById("cbpanel");
var chks = inputs.getElementsByTagName("input");
var str = "";
for (var i = 0; i chks.length; i++) {
if (chks[i].type == 'checkbox') {
str += chks[i].value + "," + chks[i].checked + "|";
}
}
document.getElementById("Hidden1").value = str;
}

script>

div id="cbpanel"> asp:Literal ID="LiteralRole" runat="server">/asp:Literal>

input id="Hidden1" runat="server" type="hidden" />/div>
