 <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
   <ContentTemplate>
     <div class="modal fade" id="myModal" data-backdrop="true">
       <div class="modal-dialog">

使用标记中的.ajax()和代码隐藏中的发送$('#UserMail')。val(),但没有结果

3 个解决方案

#1

you are using UpdatePanel.Update method which Causes an update of the content of an UpdatePanel control.I think this is clearing your textbox. try the below code

您正在使用UpdatePanel.Update方法,该方法更新UpdatePanel控件的内容。我认为这是清除您的文本框。试试下面的代码

 Protected Sub Anchor_Click() Handles anchorbutton.ServerClick

        Dim Msg As String
        Msg = "Mensaje enviado desde el formulario Contactar: " & Me.UserMail.Text
        UpdatePanel1.Update()   
 End Sub

#2

Using ajax you can do like below:

使用ajax你可以这样做:

$("#<%=anchorbutton.ClientID%>").click(function(e) {
    e.preventDefault();
    var txtVal = $("#UserMail").val();
    console.log(txtVal);
    $.ajax({
        type: "POST",
        url: "Default.aspx/MyFunction",
        data: "{'textVal':'" + txtVal + "'}",
        contentType: "application/json; charset=utf-8",
        success: function (result) {
            alert("success");
        }
    });
});


[WebMethod]
public static void MyFunction(string textVal)
{

}

If you want to do using server side add onserverclick attribute in anchor tag:

如果你想在锚标记中使用服务器端添加onserverclick属性:

<a href="#" class="btn btn-primary" runat="server" id="anchorbutton" OnServerClick="Anchor_Click">Aceptar</a>

vb code

Protected Sub Anchor_Click(sender As Object, e As EventArgs)
    UpdatePanel1.Update()
    Dim Msg As String = Nothing
    Msg = "Mensaje enviado desde el formulario Contactar: " & Convert.ToString(Me.UserMail.Text)
End Sub

The problem was code in separate asp:Content, something related to MasterPages

问题是代码在单独的asp:Content中,与MasterPages有关
