dialog父子窗口传值，有问题

父页面

 //创建窗口
    function showEditDialog(obj) {
        var objNum = arguments.length;
        var d = parent.dialog({
            id: "addorder",
            width: '100%',
            height: '500px',
            title: '修改日期',
            url: "order.aspx"
            
             
        }).showModal();
        d.button([{ value: '确定'}]);
        if (objNum == 1) {
            d.data = obj;  // 给窗体传入对象
        }

    }

<asp:Label ID="lbluserid" runat="server" Text="" name="lbluserid" ></asp:Label>

<asp:Label ID="lbl_afterdate" runat="server" Text="" class="sp_afterdate"></asp:Label>
        <input type="text" id="txt_afterdate" class="txt_afterdate" runat=server>

 

 

弹出的子页面order.aspx

        //获得父窗体传值

        var addorder = top.dialog.get("addorder"); //父页面中dialog的id设置为addorder
        //如果是第一次访问本页面，则api为空，由父窗体打开本页面，api不为空
        if ($(addorder.data).length > 0) {
            userid = $("#lbluserid", window.parent.document).text(); //获得用户id

}

  function Edit(date, time) {
        
        $(".sp_afterdate", window.parent.document).text(date + "  " + time);
        $(".txt_afterdate", window.parent.document).val(date + "  " + time);
        var d = parent.dialog({
            width: '250px',
            height: '120px',
            title: '修改日期',
            content: "已经修改，提交后保存"
        }).show();
        d.button([{ value: '确定'}])
        return false;


    }

 

//这里保存成功后不能关闭子窗口，求各路大神补充完整
