【问题描述】：
我怎样才能获得 25 行记录并在每次滚动时动态地将它们放入表中
<div class="UserList">
<table id="tblUsers"></table>
</div>
我有一些 JQuery 客户端代码来请求这样的数据
$(".UserList").scroll(function () {
var iframe = $(".UserList");
var tr = iframe.contents().find("tr[name=25]");
$.ajax({
type: "POST",
url: "UserListing.aspx/GetNRecods",
data: '{Lower:' + tr + ',Upper: ' + tr + '}',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (data) {
$("#tblUsers").html(data.d);
}
});`
我的后端代码是
<System.Web.Services.WebMethod()> _
Public Shared Function GetNRecords(ByVal Upper As Integer, ByVal Lower As Integer) As String
Dim oUserinfo As New ClassUser
Dim dvUserlist As New DataView
dvUserlist = oUserinfo.GetNRecords(Upper, Lower)
Dim strData As String
strData = "<tr id='Header'><td>UserID</td><td>UserName</td><td>Created Date</td><td>Email</td><td>FirstName</td><td>LastName</td><td>Mobile No.</td><td>Address</td><td>Country</td><td colspan='2'>Action</td><td>Status</td></tr>"
For i As Integer = 0 To dvUserlist.Table.Rows.Count - 1
Dim Txt As String
Txt = CStr(dvUserlist.Table.Rows(i)("IsActive").ToString())
If Txt = False Then
Txt = "Inactive"
Else
Txt = "Active"
End If
strData += "<tr><td id='userID'>" + dvUserlist.Table.Rows(i)("userID").ToString() + "</td><td id='UserName'>" + dvUserlist.Table.Rows(i)("username").ToString() + "</td><td id='Date'>" + CDate(dvUserlist.Table.Rows(i)("CreatedDate").ToString()).ToString("dd/MM/yyyy") + "</td><td id='Email'>" + dvUserlist.Table.Rows(i)("Email").ToString() + "</td><td id='FirstName'>" + dvUserlist.Table.Rows(i)("FirstName").ToString() + "</td><td id='LastName'>" + dvUserlist.Table.Rows(i)("LastName").ToString() + "</td><td id='Phone'>" + dvUserlist.Table.Rows(i)("Phone").ToString() + "</td><td id='Address'>" + dvUserlist.Table.Rows(i)("Address").ToString() + "</td><td id='Country'>" + dvUserlist.Table.Rows(i)("country").ToString() + "</td><td id='Edit'> <a id='lnkEdit'" & dvUserlist.Table.Rows(i)("userID").ToString() & "' onclick='window.open(""InsertUserInfo.aspx?userid=" & dvUserlist.Table.Rows(i)("userID").ToString() & """)'> Edit </a>" + "</td><td id='Delete'> <a id='LnkDelete'" & dvUserlist.Table.Rows(i)("userID").ToString() & "' onclick='DeleteUserinfo(""" & dvUserlist.Table.Rows(i)("userID").ToString() & """);'>Delete</a></td><td><span class='IsActive' id='IsActive" & dvUserlist.Table.Rows(i)("userID").ToString() & "' onclick='UpdateUserStatus(" & dvUserlist.Table.Rows(i)("userID").ToString() & ")'>" + Txt + "</span></td></tr>"
Next
Return strData
End Function

正确对齐代码以便于理解。

太好了，我想
it's正在尝试交流。 -
如果你问的是无限滚动 - 先尝试谷歌 - 你可能会找到很多东西。我也回答过类似的问题：stackoverflow.com/questions/19370850/…

@TheDean 甚至不清楚你的问题是什么......你已经将客户端代码和服务器代码转储到帖子中，并对问题进行了简单的解释。我们如何知道什么有效，什么无效，或任何意外行为。任何读者都应该清楚应该关注什么
