我正在尝试在我的 asp.net 网页上获取日期选择器。我已经能够使用母版页运行相同的代码并且它可以工作，但现在我试图让它在没有母版页的情况下工作，我收到错误消息：错误：无法获取属性的值'aspnetForm.ctl00_txtDOB': 对象为空或未定义

在我的 Default.aspx 页面上......

<script language="javascript" type="text/javascript">
    function calendarPicker(strField) {
        window.open('date_picker.aspx?field=' + strField, 'calendarPopup', 'width=250,height=190,resizable=yes');
    } 


        <label>DOB:</label><asp:TextBox ID="txtDOB" runat="server"></asp:TextBox>
       <img src="images/calendar.gif" alt="Pick To Date" onclick="calendarPicker('aspnetForm.ctl00_txtDOB');"/>

      I already tried onclick="calendarPicker('txtDOB');"/>


My date_picker.aspx.cs
        private void Calendar1_DayRender(object sender, System.Web.UI.WebControls.DayRenderEventArgs e)
        {

            // Clear the link from this day
            e.Cell.Controls.Clear();

            // Add the custom link
            System.Web.UI.HtmlControls.HtmlGenericControl Link = new System.Web.UI.HtmlControls.HtmlGenericControl();
            Link.TagName = "a";
            Link.InnerText = e.Day.DayNumberText;
            Link.Attributes.Add("href", String.Format("JavaScript:window.opener.document.{0}.value = \'{1:d}\'; window.close();", Request.QueryString["field"], e.Day.Date));




            // By default, this will highlight today's date.
            if (e.Day.IsSelected)
            {
                Link.Attributes.Add("style", this.Calendar1.SelectedDayStyle.ToString());
            }



            // Now add our custom link to the page
            e.Cell.Controls.Add(Link);

        }

尝试改变这个：

onclick="calendarPicker('aspnetForm.ctl00_txtDOB');"

对此：

onclick="calendarPicker('<%=txtDOB.ClientID %>');"

我通过这样做使它工作：

添加表单[0].... window.opener.document.forms[0].{0}.value..........

Link.Attributes.Add("href", String.Format("JavaScript:window.opener.document.forms[0].{0}.value = \'{1:d}\'; window.close(); ", Request.QueryString["field"], e.Day.Date));
