Ajax读取txt并对txt内容进行分页显示功能

这篇文章给大家介绍了Ajax读取txt并对txt内容进行分页显示功能,非常不错,具有参考借鉴价值,感兴趣的朋友一起看看吧

下文给大家分享了ajax读取txt并对txt内容进行分页显示的核心代码,废话不多说了,直接贴代码了。

function TransferString(content)
{
var string = content;
try{
string=string.replace(/\r\n/g,"
") string=string.replace(/\n/g,"
"); string=string.replace(/[ ]/g," ") string=string.replace(/\ +/g," ") }catch(e) { alert(e.message); } return string; } var pageIndex = 1; var id = $("#aId").val(); var url = $('#urlArticleContent').val(); var txt = ''; 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 = []; for (var i = 1; i < pageCount; i++) { result.push(i); } done(result); }, pageCount:pageCount, pageSize: 5, showGoInput: true, showGoButton: true, callback: function(data, pagination) { // template method of yourself var html = template(data); dataContainer.html(html); } }) } else { txt = ''; } } }) function GoHead() { GoPage(1); } function NextClick() { if (pageIndex < pageCount) { pageIndex = pageIndex + 1; } else { pageIndex = pageCount; } GoPage(pageIndex); $("#pageCurrent").html(pageIndex); } function backClick() { if (pageIndex > 1) { pageIndex = pageIndex - 1; GoPage(pageIndex); $("#pageCurrent").html(pageIndex); } } function GoPageNew() { var page=$("#pageGo").val(); GoPage(page); opts.current=page; } function GoPage(pageIndex) { if(pageIndex==0) { pageIndexStr = $('#goPage').val(); if (pageIndexStr==undefined) { return false; } pageIndexStr = pageIndexStr.trim(); var pageIndex = parseInt(pageIndexStr); } $('#page'+pageIndex).siblings().removeClass('active'); $('#page'+pageIndex).addClass('active'); if (pageIndex==1) { if(!$('#backClick').hasClass('disabled')) { $('#backClick').addClass('disabled'); } } else { $('#backClick').removeClass('disabled'); } if (pageIndex == pageCount) { if(!$('#nextClick').hasClass('disabled')) { $('#nextClick').addClass('disabled'); } } else { $('#nextClick').removeClass('disabled'); } var pageTxt = txt.substring((pageIndex - 1) * pageSize, pageIndex * pageSize); $('#word').html(TransferString(pageTxt)); $('html, body').animate({ 'scrollTop': 0 }, 0); $("#pageCurrent").html(pageIndex); } function PageGo(){ if($('.jump-ipt').val()!=''){ GoPage($('.jump-ipt').val()) } } @{ if (null != ViewBag.Ariticle) { DataRow dr = ViewBag.Ariticle; if (null != dr) { ViewBag.Title = dr["Title"];

@dr["Title"]

1/0
} } }

txt文件上传时需要做一些处理,否则只能显示UTF8格式的txt

/// 
/// 文件上传
/// 
/// 
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 = "" });
}
}

另外页面首页引入js
