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,"<BR>")
string=string.replace(/\n/g,"<BR>");
string=string.replace(/[ ]/g,"&nbsp;")
string=string.replace(/\ +/g,"&nbsp;")
}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');

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())

txt文件上传时需要做一些处理,否则只能显示UTF8格式的txt

/// <summary>
/// 文件上传
/// </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 = "" });
}
}

另外页面首页引入js

<script src="/UploadFiles/2021-04-02/jquery.pagination.js">
