ajax：
mui.ajax('http://server-name/login.php',{data:{username:'username',password:'password'},dataType:'json',//服务器返回json格式数据type:'post',//HTTP请求类型timeout:10000,//超时时间设置为10秒；success:function(data){//服务器返回响应，根据响应结果，分析是否登录成功； ...},error:function(xhr,type,errorThrown){//异常处理； console.log(type);}});
后台php：
<?php header('Content-type:text/html; Charset=utf8'); header( "Access-Control-Allow-Origin:*"); header('Access-Control-Allow-Methods:POST'); header('Access-Control-Allow-Headers:x-requested-with,content-type'); include('../../conn.php'); include('../../luanma.php'); $sql="select * from news where class='校园新闻' order by time ASC"; mysql_query("SET NAMES utf8"); $result= mysql_query($sql); while($array=mysql_fetch_array($result ,MYSQL_ASSOC)){ $tt[]=array('tittle'=>$array["tittle"],'txt'=>$array["text"],'source'=>$array['source'],'date'=>$array['date']); } echo json_encode($tt); mysql_close(); ?>
必不可少的：
header('Content-type:text/html; Charset=utf8'); header( "Access-Control-Allow-Origin:*"); header('Access-Control-Allow-Methods:POST'); header('Access-Control-Allow-Headers:x-requested-with,content-type');
