下文給大家分享了ajax讀取txt並對txt內容進行分頁顯示的核心代碼，廢話不多說了，直接貼代碼了。

function TransferString(content)
{
var string = content;
try{
string=string.replace(/\r\n/g,"<BR>")
string=string.replace(/\n/g,"<BR>");
string=string.replace(/[ ]/g," ")
string=string.replace(/\ +/g," ")
}catch(e) {
alert(e.message);
}
return string;
}

var pageSize = @(ConfigurationManager.AppSettings["ArticlepageSize"]);
var page=5;
var pageCount = 0;
$(function() {
if(url!="")
{
txt = ($.ajax({ url: url, async: false })).responseText;
if (txt.indexOf('http://www.w3.org/1999/xhtml')==-1) {
pageCount = Math.ceil(txt.length / pageSize);
$("#PageCount").html(pageCount);
$('#word').html(TransferString(txt.substring(0, pageSize)));
$('#demo').pagination({
dataSource: function(done){
var result = [];

result.push(i);
}

},

// template method of yourself
var html = template(data);
dataContainer.html(html);
}
})
} else {

}
}
})
function GoHead() {
GoPage(1);

txt文件上傳時需要做一些處理，否則只能顯示UTF8格式的txt

/// <summary>
/// 文件上傳
/// </summary>
/// <returns></returns>
public JsonResult UploadFiles()
{

HttpPostedFileBase postFile = HttpContext.Request.Files["filesave"];
if (postFile != null)
{
string fileName = Path.GetFileName(postFile.FileName);
string fileExt = Path.GetExtension(fileName.ToLower());
string fileSize = postFile.ContentLength.ToString();
long fileNameTem = Common.GenerateLongId();
string sPath = string.Format("/Data/Material/{0}_{1}.txt", fileNameTem.ToString(), fileName.Replace(".txt", ""));//Guid.NewGuid().ToString().Replace("-", "")
string viewUrl = string.Empty;
string g = Guid.NewGuid().ToString();
if (!Directory.Exists(Server.MapPath("~") + "/Data/Material"))
Directory.CreateDirectory(Server.MapPath("~") + "/Data/Material");
string p = Server.MapPath(sPath);
postFile.SaveAs(p);

if (System.IO.File.Exists(p))
{
StreamReader sr = new StreamReader(p, System.Text.Encoding.Default);
String input = sr.ReadToEnd();
sr.Close();

StreamWriter sw = new StreamWriter(p, false, System.Text.Encoding.UTF8);
sw.WriteLine(input);
sw.Close();
}
return Json(new { FilePath = sPath, FileName = fileName, viewurl = viewUrl, fileSize = fileSize });
}
else
{
return Json(new { FilePath = "" });
}
}

另外頁面首頁引入js

<script src="~/Scripts/web/jquery.pagination.js"></script>
