sort json by jquery key value [duplicate]

Sorting a JavaScript object

I have a json data like this

[
  {
    "name":"anand",
    "type":"0"
  },
  {
    "name":"bajaj",
    "type":"0"
  },
  {
    "name":"cat",
    "type":"1"
  }
]

I populate these data in a table with header, name and type.

I have stored these data in a javascript global array. Now i have to sort that global array according to key.

For example when i click the name it has to sort according to name and same for type.

I have tried many things but it is giving sort is not a function error.

var data_obj= [];  // declared a global variable 

 $.ajax({url: url,
         type:"post",
         data: "folder="+folder,
         success: function(data){
             data_obj = data // here i store returned json data in a global variable 
         }  
 });

a simple sort function

 data_obj.sort(function(a, b){
     return [a.name] < [b.name] ? -1 : 1;
 });

But it is giving me sort is not a function. Please help me in sorting according to key.

Why are you wrapping the two names in arrays and then comparing the arrays? — Quentin

See the dupe. It's your exact question and, nope, it cannot be done. — Álvaro González

Presumably the server is sending the JSON back with the wrong Content-Type (it is common for people writing PHP to forget to override the default HTML content type with header('Content-Type: application/json');).

This would result in data being an HTML DOM instead of an Array inflated from JSON, so it wouldn't have a sort method.

I have inserted type as contentType: 'application/json', in ajax call still it is giving same error

Quentin Over a year ago

@user1403248 — The contentType property is documented such When sending data to the server, use this content type. It doesn't make any difference to the response (unless the server reacts to getting a JSON request by 500ing or otherwise not giving you the data you want at all). It is the HTTP Content-Type header in the response you need to change.
