本文實(shí)例講述了.net的ajax請(qǐng)求數(shù)據(jù)提交實(shí)現(xiàn)方法。分享給大家供大家參考。具體如下：
復(fù)制代碼 代碼如下:<%@ page language=c# inherits=system.web.mvc.viewpage<dynamic> %>
<head runat=server>
<title>ajax請(qǐng)求</title>
<link type=text/css rel=stylesheet href=/content/style.css />
<script type=text/javascript src=/scripts/jquery-1.8.3.min.js></script>
<script type=text/javascript src=/scripts/js.js></script>
</head>
<body>
<!--頂部+logo+導(dǎo)航-->
<div class=logo_box>
<div id=logo>
<a title=ajax請(qǐng)求>ajax請(qǐng)求</a></div>
</div>
<!---->
<div class=logincon>
<div class=loginbanner>
<img src=/images/4499633_182932517000_2.jpg /></div>
<div class=loginbox>
<h2>
<span class=fl>會(huì)員登錄</span><span class=newuser>沒(méi)有賬號(hào)？<a href='<%=url.action(register,account) %>'>立即注冊(cè)</a></span></h2>
<form id=formdata>
<div class=loginform>
<div class=inputbox>
<input type=text name=user value=用戶名/手機(jī)號(hào) class=userid />
</div>
<div class=inputbox>
<input type=text value=密碼 class=textstyle />
<input type=password name=pwd class=passwordstyle none />
</div>
<div class=warn>用戶名或密碼錯(cuò)誤！</div>
<div class=remember>
<label>
<input type=checkbox name=remembered checked />
自動(dòng)登錄</label>
<a class=forget href='<%=url.action(resetpwd,login) %>' >忘記密碼？</a>
</div>
<input class=loginbtn type=button value=登錄/>
</div>
</form>
</div>
</div>
</body>
<script type=text/javascript>
$(function () {
$('.userid,.passwordstyle').on('keyup', function (e) {
if (e.keycode == 13) {
$('.loginbtn').trigger('click');
}
});
$('.loginbtn').on('click', function () {
$(.warn).hide();
var pwd = $('.passwordstyle').val();
if (pwd == '') {
$(.warn).show().html('請(qǐng)輸入密碼');
return false;
}
var data = $(#formdata).serialize();
$.post(/login/checklogininfo, data, function (ajaxobj) {
//回傳內(nèi)容{status: 1(success)/0(fail),}
if (ajaxobj.status == 0 || status == null) {
$(.warn).show().html('用戶名或密碼錯(cuò)誤！');
} else {
//登陸成功，跳轉(zhuǎn)都制定頁(yè)面
window.location = '/membercenter/index';
}
}, json);
});
});
</script>
</html>
控制器
復(fù)制代碼 代碼如下:using system;
using system.collections.generic;
using system.linq;
using system.web;
using system.web.mvc;
using system.text;
namespace bigtree.controllers
{
using bigtree.models;
using bigtree.model;
using bigtree.lib;
using system.net.mail;
using system.text.regularexpressions;
public class logincontroller : controller
{
public actionresult index()
{
return view();
}
/// <summary>
/// 檢查登陸
/// </summary>
/// <param name=f></param>
/// <returns></returns>
[httppost]
public actionresult checklogininfo(formcollection f)
{
try
{
//post: user , pwd ,remembered
string user = f[user].trim();
string pwd = f[pwd].trim();
string remembered = f[remembered].trim();
jsonresult res = new jsonresult();
if (string.isnullorempty(user) || string.isnullorempty(pwd))
{
res.data = new { status = 0 };
}
//md5加密后的密碼
pwd = system.web.security.formsauthentication.hashpasswordforstoringinconfigfile(pwd, md5).tolower();
//從數(shù)據(jù)庫(kù)讀取
common.webuser account = memberinfoservice.getmemberidforcheck(user, pwd);
if (account == null)
{
res.data = new { status = 0 };
}
else
{
//{status: 1(success)/0(fail),}
res.data = new { status = 1 };
//todo：登陸成功，記錄登陸用戶信息保存登陸狀態(tài)
funsession.setsession(account);
//是否記住登錄
if (remembered == on)
{
httpcookie cookie = new httpcookie(logininfo, account.id.tostring());
//3天有效
cookie.expires.adddays(3);
response.cookies.add(cookie);
}
else
{
httpcookie cookie = new httpcookie(account.id.tostring(), account.id.tostring());
//使失效
cookie.expires.addyears(-1);
response.cookies.add(cookie);
}
}
return res;
}
catch (exception ex)
{
throw ex.innerexception;
}
}
}
}
希望本文所述對(duì)大家的.net程序設(shè)計(jì)有所幫助。
