PHP js使用ajax异步处理方式请求PHP，解决数组中文乱码

html端：

<html>
<head>
<script type="text/javascript" src="jquery/jquery.min.js"></script>
<script>
function send()
{
    $.ajax({
            type:"POST",
            url:"server.php",
            data:{Name:"admin",Password:"sanmaoword"},       
            datatype: "html",//"xml", "html", "script", "json", "jsonp", "text".          
            beforeSend:function(){
                $("#msg").html("logining");
            },            
            success:function(data){
                //$("#msg").html(decodeURI(data));           
                var str = data;
                $("#msg").html(str);
                str = eval("'" + str + "'");//把Unicode转为中文
                $("#msg").html(str);                
            }, 
            complete: function(XMLHttpRequest, textStatus){
               //alert(XMLHttpRequest.responseText);
               //alert(textStatus);
                //HideLoading();
            },            
            error: function(){
              
            }        
         });
}

</script>
</head>
<body>
<input type="button" onclick="send()" value="send"/>
</br>
<label id="msg"></label>
</body>
</html>

php端：

<?php
//header('Content-Type:text/html;charset=GB2312'); 
if($_POST['Name']=="admin")
{
	$info=array("fuck","张明L");
	array_push($info,"王郎");
	echo json_encode($info);
}
?>
