前端js+html代码

<p><!DOCTYPE HTML><html><head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta name="viewport" content="width=device-width,initial-scale=1,user-scalable=no,maximum-scale=1" /> <link rel="stylesheet" href="ZZZZZZZZZZZZZZZZZZZ/js_css/reset.css"> <script src="ZZZZZZZZZZZZZZZZZ/js_css/jquery-1.8.3.min.js"></script> <script>  function load()  {   $.getJSON("ZZZZZZZZZZZZZZZZZZZZZZ/b.php?callback=?",   {     'username':"jack",     'password':"123456"        },      function(data){       if(data.result=="pass")    {     document.getElementById("id").innerHTML=data.content.userid;     document.getElementById("name").innerHTML=data.content.name;     document.getElementById("age").innerHTML=data.content.age;     document.getElementById("gender").innerHTML=data.content.gender;     document.getElementById("subs0").innerHTML=data.content.subs[0];     document.getElementById("subs1").innerHTML=data.content.subs[1];     document.getElementById("subs2").innerHTML=data.content.subs[2];    }   });  } </script> <title>title</title></head></p><p><body onload="load()"> <div id="id"></div> <div id="name"></div> <div id="age"></div> <div id="gender"></div> <br/><br/> <div id="subs">  <div id="subs0"></div>  <div id="subs1"></div>  <div id="subs2"></div> </div></body></p><p></html></p>

后端php代码

注意后端接到js的数据进行mysql存储时,要htmlspecalchars 和addslashes对&<>\ " " 进行处理，否则会出异常。

<?php$content = array("userid"=>addslashes($_GET['userid']),"name"=>addslashes("rose"),"age"=>addslashes("20"),"gender"=>addslashes("female"),"subs"=>array(addslashes("maths"),addslashes("geo"),addslashes("phy")));$result="pass";$ret = array("result"=>$result,"content"=>$content,"mask"=>"mask");echo $_GET['callback']."(".json_encode($ret).")";
