我想使用jquery在我的aspx页面中获取usercontrol标签值。这是我的用户控件

    <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Group.ascx.cs" Inherits="website.Inventory.Setup.UserControl.Group" %>
    <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>
    <style type="text/css">
        .style1
        {
            width: 100%;

        }
        .style2
        {
            width: 12%;
        }
    </style>
    <table class="style1">

                        <td>
                            &nbsp;&nbsp;
                        </td>
                    </tr>
                </table>
            </td>
        </tr>

</table>

这是我的控件

<uc1:Group ID="UCGroup" ClientIDMode="Static"  runat="server" />

我想在我的aspx页面中获取lblmsgAdd值，我这样做

 var a = $('#<%=UCGroup.ClientID%>').find('#<%=lblmsgAdd.ClientID%>').val();

但这不起作用，我如何获得我的标签价值。需要帮助

Answer 1

在您的用户控件中创建一个公共属性，返回您的Label的ClientID，如下所示

public string AddMessageClientId
{
   get
   {
      return lblmsgAdd.ClientID;
   }
}

然后在你的JQuery中调用它，如下所示

var a = $('#<%= AddMessageClientId %>').val();

使用asp.net中的jquery获取用户控件元素值
