jQuery post json why no response?

Question

JavaScript

1.php

var arr = {"token":"123"};
  $.ajax({
    url: '2.js',
    type: 'POST',
    data: JSON.stringify(arr),
    contentType: 'application/json; charset=utf-8',
    dataType: 'json',
    //async: false,
    success: function (r) {
      console.log('res');
        console.log(r);
    }
});

2.js How to get a response without removing / *xxx*/ ? (without them everything works)
/*xxx*/{"result":"1000"}/*xxx*/

Answer 1

dataFilter: function(response) {
return response.replace("/*xxx*/","").replace("/*xxx*/","");
},

Answer 2

as far as I understand, your POST request is not processed by the server? It just returns the contents of 2.js
And most likely the server is doing everything right, and your only problem is that /*xxx*/{"result":"1000"}/*xxx*/- is not a valid JSON.

Answer 3

get how plain text
cut comments regex
parse as json
