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，具有参考和学习ajax的价值，对ajax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"]
}
}
}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
