我看了几篇关于这个topc的帖子。我注意到一个代码。我也在下面的代码网址上使用相同的代码。 Binding asp.net datalist with jQuery

function OnSuccess(response) {
            $("[id*=dlOnFrontPageProducts]").attr("border", "1");
            var xmlDoc = $.parseXML(response.d);
            var xml = $(xmlDoc);
            var customers = xml.find("Table1");
            var row = $("[id*=dlOnFrontPageProducts] tr:last-child").clone(true);
            $("[id*=dlOnFrontPageProducts] tr:last-child").remove();
            $.each(customers, function () {
                alert(this);
                var customer = $(this);
                $(".Name", row).html(customer.find("Name").text());
                $(".BrandName", row).html(customer.find("BrandName").text());
                $(".MarketPrice", row).html(customer.find("MarketPrice").text());
                $(".CurrencyShortName", row).html(customer.find("CurrencyShortName").text());
                $(".Price", row).html(customer.find("Price").text());
                $(".WindowImageUrl", row).html(customer.find("WindowImageUrl").text());
                $(".SaleCount", row).html(customer.find("SaleCount").text());
                $(".IsActive", row).html(customer.find("IsActive").text());
                $("[id*=dlOnFrontPageProducts]").append(row);
                row = $("[id*=dlOnFrontPageProducts] tr:last-child").clone(true);
            });
        }

如何使用ajax和jquery进行绑定。我的页面需要16秒才能加载页面。那就是我要去jquery。

请帮我找到解决方案......

Answer 1

您将无法通过jQuery Bind DataList控件，因为控件仅在通过服务器端代码绑定时创建，例如：关于背后的代码。

如果您想对bind控件使用Ajax和jQuery，那么您最好使用普通的旧HTML。

或者，将DataList与某些数据绑定，以便呈现它，然后在页面上创建HTML元素，您就可以使用它们。

我使用回调方法实现了这个概念而没有回发。代码如下：

 Dim callback As String = ClientScript.GetCallbackEventReference(Me, "message", "processMyResult", "context")
        Dim script As String = "function CallBack(message,context){" + callback + ";}"
        ClientScript.RegisterClientScriptBlock(Me.GetType(), "CB", script:=script, addScriptTags:=True)



 Public Sub RaiseCallbackEvent(ByVal eventArgument As String) Implements System.Web.UI.ICallbackEventHandler.RaiseCallbackEvent
    If (eventArgument) Is Nothing Then

        returnValue = "-1"

    Else

        binddata(eventArgument)
    End If



    Dim sb As System.Text.StringBuilder = New System.Text.StringBuilder()
    Dim sw As System.IO.StringWriter = New System.IO.StringWriter(sb)
    Dim hw As HtmlTextWriter = New HtmlTextWriter(sw)
    gvCustomers.RenderControl(hw)
    returnValue = sb.ToString()

End Sub

Public Function GetCallbackResult() _
As String Implements _
System.Web.UI.ICallbackEventHandler.GetCallbackResult

    Return returnValue

End Function

Public Function binddata(ByVal eventArgument As String) as nullable
    Dim adp As New dsRegistrationTableAdapters.searchPackagesTableAdapter()
    Dim dt As New dsRegistration.searchPackagesDataTable()
    dt = adp.GetData(eventArgument, StartDateTextBox.Text, EndDateTextBox.Text)


    gvCustomers.DataSource = dt
    gvCustomers.DataBind()
    SearchTextBox.Focus()


End Function
