使用ajax实现表单提交无刷新页面在项目中经常会用到。前一段时间跟着师傅学到了另外几种无刷新提交表单的方法,主要是基于iframe框架实现的。现在整理出来分享给大家。
第一种:
(html页面)
- nbsp;HTML>
- "en-US">
- "utf-8">
无刷新提交表单 - >
- ul{ list-style-type:none;}
- "text" name="uname" id="uname" />
- "password" name="pwd" id="pwd" />
- "submit" value="登录" />
- (PHP页面:form.php)
- //非空验证
- if(empty($_POST['uname']) || empty($_POST['pwd']))
- {
- echo '<script>alert("用户名或密码为空!");</script>';
- exit;
- }
- //验证密码
- if($_POST['uname'] != 'jack' || $_POST['pwd'] != '123456')
- {
- echo '<script>alert("用户名或密码不正确!");</script>';
- exit;
- } else {
- echo '<script>alert("登录成功!");</script>';
- exit;
- }
第二种:
(html页面)
- nbsp;HTML>
- "en-US">
- "utf-8">
iframe提交表单 - 用户名:"text" name="username" />
- 密 码:"password" name="userpwd" />
- "submit" value="登录" />
- <script><span class="string">"text/javascript"</script>>
- function iframeLoad(iframe){
- var doc = iframe.contentWindow.document;
- var html = doc.body.innerHTML;
- if(html != ''){
- //将获取到的json数据转为json对象
- var obj = eval("("+html+")");
- //判断返回的状态
- if(obj.status
- alert(obj.msg);
- }else{
- alert(obj.msg);
- window.location.href="http://www.baidu.com";
- }
- }
- }
(PHP页面:form.php)
- php
- //设置时区
- date_default_timezone_set('PRC');
- /*
- 返回的提交消息
- status:状态
- msg:提示信息
- */
- $msg = array('status'=>0,'msg'=>'');
- //获取提交过来的数据
- $name = $_POST['username'];
- $pwd = $_POST['userpwd'];
- //模拟登录验证
- $user = array();
- $user['name'] = 'jack';
- $user['pwd'] = 'jack2014';
- if($name != $user['name']){
- $msg['msg'] = '该用户未注册!';
- $str = json_encode($msg);
- echo $str;
- exit;
- }else if($pwd != $user['pwd']){
- $msg['msg'] = '输入的密码错误!';
- $str = json_encode($msg);
- echo $str;
- exit;
- }
- $msg['msg'] = '登录成功!';
- $msg['status'] = 1;
- $str = json_encode($msg);
- echo $str;
