我嘗試通過使用腳本更新標籤。在腳本之後,每個Label.value已經有數據,但它不在頁面上更新。這裏是我的代碼:ASP。 NET標籤不更新與jQuery的ajax/POST

ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "a", @" <script type='text/javascript'> 
     function bbfb() { 
      $.ajax({ 
       type: 'POST', 
       url: 'ImgService.asmx/GetAllImgs', 
       data: '{}', 
       contentType: 'application/json; charset=utf-8', 
       dataType: 'json', 
       async: false, 
       success: function (msg) { 
        var cars = msg.d; 
        var TextBoxError = document.getElementById('Labelxyz123'); 
        var TextBoxError1 = document.getElementById('LabelLogContent'); 
        TextBoxError.value = cars; 
         TextBoxError1.value = cars; 
       }, 
       failure: function (msg) { 
        alert('fail'); 
       } 
      }); 
     } 

     function BindEvents() { 
      setTimeout(function() { 
       bbfb(); 

      //At this point, all of the labels already have data 
      var TextBoxError = document.getElementById('Labelxyz123'); 
      var TextBoxError1 = document.getElementById('LabelLogContent'); 
      alert(TextBoxError.value); 
      alert(TextBoxError1.value); 
      // 

      }, 0); 
     } 
     BindEvents(); 

</script>", false); 
      UpdatePanelEdit_on.Update(); 

這裏是我的ASP代碼:

<asp:Label ID="Labelxyz123" runat="server" ClientIDMode="Static" Text="a"></asp:Label> 

    <asp:UpdatePanel ID="UpdatePanelEdit_on" runat="server" UpdateMode="Conditional" 
     ChildrenAsTriggers="false"> 
     <ContentTemplate> 
     <asp:Label ID="LabelLogContent" ClientIDMode="Static" runat="server" Text="a"></asp:Label> 
    </ContentTemplate> 
     <Triggers> 
     </Triggers> 
    </asp:UpdatePanel> 

兩個標籤內外更新面板並沒有更新。

我終於找到了我的問題。解決這個問題的辦法是改變異步成真

async:true 

變化

var TextBoxError = document.getElementById('LabelLogContent'); 
TextBoxError.value = cars; 

$('#LabelLogContent).Text = cars 

問題是標籤沒有從客戶端更新。
