javascript - Help! ! ! About mui ajax unable to obtain background data

The js code is as follows

mui.init(); mui.ajax('ajax.php', { dataType: 'json', //服务器返回json格式数据 type: 'post', //HTTP请求类型 headers: { 'Content-Type': 'application/json' }, success: function(data) { alert(data)//就像获取后台php的数据啊！！！ }, async:true, error: function(xhr, type, errorThrown) { alert(errorThrown);//好像报类型错误？php那边是json格式啊 } }); php code is as follows error_reporting(E_ALL ^ E_DEPRECATED); //header("Content-type: text/html; charset=utf-8"); header('Content-type: text/json ; charset=utf-8'); //header('Content-type: application/json'); //There is a bit of doubt about this header~ I have tried everything but it still doesn’t work $arr = array(

'name' => '我是姓名', 'age' => '18'

); $json_string = json_encode($arr); echo ($json_string);//The output here is the json string~~ ?>

It should be that the front-end and back-end formats do not match. Try removing ajax dataType: "json". The obtained data is String, and then convert it to json in the front-end.
