HTML无刷新提交表单 - jerrylsxu

通常对于无刷新提交表单,我们都是运用ajax实现的。前段时间跟着老大了解到另一种无刷新提交表单的方法,是利用iframe框架实现的。现在整理出来分享给大家。
第一种:
(html页面)
doctype html>html lang=en-us>head> meta charset=utf-8> title>无刷新提交表单title> style type=text/css> ul{ list-style-type:none;} style>head>body> iframe name=formsubmit style=display:none;> iframe>
form action=form.php method=post name=formphp target=formsubmit> ul> li> label for=uname>用户名:label> input type=text name=uname id=uname /> li> li> label for=pwd>密 码:label> input type=password name=pwd id=pwd /> li> li> input type=submit value=登录 /> li> ul> form>body>html>
(php页面:form.php)
php //非空验证 if(empty($_post['uname']) || empty($_post['pwd'])) { echo ''; exit; } //验证密码 if($_post['uname'] != 'jack' || $_post['pwd'] != '123456') { echo ''; exit; } else { echo ''; exit; }
第二种:
(html页面)
doctype html>html lang=en-us>head> meta charset=utf-8> title>iframe提交表单title>head>body> iframe name=myiframe style=display:none; onload=iframeload(this);>iframe> form action=form.php target=myiframe method=post> 用户名:input type=text name=username />br/> 密 码:input type=password name=userpwd />br/> input type=submit value=登录 /> form> script type=text/javascript> 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 1){ alert(obj.msg); }else{ alert(obj.msg); window.location.href=http://www.baidu.com; } } } script>body>html>
(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;
