在ASP.NET中ShowModalDialog+ztree的使用

.aspx:

<script type="text/javascript">
    function getReturnValue() {
        var strResult = window.showModalDialog('Depart.aspx?random=' + Math.random(), "", "dialogWidth=400px;dialogHeight=500px;status:no");
        if (strResult != undefined) {
            var str = new Array();
            str = strResult.split("|");
            $("#hidId").val(str[0]);
            $("#hidName").val(str[1]);
            $("#txtDepart").val(str[1]);
            //alert(str[1]);
        }
    }
</script>

<table width="100%" border="0" cellspacing="0" cellpadding="0">
    <tr>
            <td>
                请选择：
            </td>
            <td>
                <asp:TextBox ID="txtDepart" runat="server" CssClass="input required" onclick="getReturnValue();" size="30" ReadOnly="True"></asp:TextBox>
                <asp:HiddenField ID="hidId" runat="server" />
                <asp:HiddenField ID="hidName" runat="server" />
            </td>
        </tr>
</table>

.aspx.cs:只需保存hidId的值
