Question

我想将数据附加到转发器，转发器已经在页面加载时有一些数据。但我想在滚动页面时重新加载数据。

<script type="text/javascript">


        $(window).scroll(function () {
            if ($(window).scrollTop() + $(window).height() == $(document).height()) {
                showData();
            }
        });


        function showData() {
            PageMethods.getData(onSuccess, onError);  // getData is a page webmethod thats return five record in json string.
            function onSuccess(data) {
                alert(data); // data has all five record.
            }
            function onError(data) {
                alert('Problem');
            }
        }

    </script>

.NET

        <div id="Posts" class="container-fluid padded">
            <asp:Repeater ID="PostsRepeater" runat="server">

在窗口滚动中，您可以创建 jQuery Ajax call which returns data ，并且在成功方法上获取响应并将其绑定到您的父Div Posts（即重复控件）

编辑：绑定数据的代码.i.e（Ajax成功方法）

function OnSuccess(response) {
    var items = response.d;
    var fragment='';
    $.each(items, function (index, val) {

    var aData_imgSRC= val.imgSRC;
    var aData_USERNAME= val.USERNAME;        

     // ..... 

   fragment += "<section> <div class='col-md-2'>  <img src='"+aData_imgSRC+"'   class='img-circle img-responsive' />  </div>   <div class='col-md-10'>    <div>   <b>"+aData_USERNAME+"</b><p><span class='glyphicon glyphicon-time'></span>Posted on Feb "+aData_Date+"></p> </div>  <hr>   <p>"+aData_Status+"</p>    <img src='images/1451285316491.jpg' class='img-responsive'></div>  </section>";
    });
    $('#Posts').append(fragment);
}
