javascript - How to get specific value from JSON result return from REST call -

I am trying to get a value from the json result which returned to my JavaScript via an RET call. Below is a JSON result of REST

  {"self": "http://example.com/rest/api/2/project/MTS/role/10002", "name": " "{{" Id ": 10803," displayName ":" administrator "," type ":" id ":" id ":" id ": 10002," Description ":" A project role that represents administrators in a project "," actor ": [ ":" Atlasian-user-roll-actor "," name ":" admin "," avatar url ":" / secure / userwater? Size = small and avatar id = 10108 "}, {" id ": 10590, DisplayName ":" Jirra-Administrator "," Type ":" Atlasian-Group-Role-Actor "," Name ":" Cicero-Administrator "," Av "We are only required to bring the name of all the actors," "Tarryl": "/ secure / user avatar = size = small and avatar ID = 10123"}]}   
 The script can help with  
  function getName () {var user; $ Ajax ({url: "/ rest / API / 2 / project / mits / roll / 10002", type: 'received', data type: 'jason', async: wrong, success: work (data) {user = data; }}); Return user; }   
 The above script is not correct   
 
 
 Success function in , Use it  
  users = []; // You will store names here $ .each (data, functions, (i, actor) {if (actor.type === "Atlasian-user-role-actor") {users.push (actor.name) ;}}}   
 In the user you will get actor name  
 If you wish, copy paste your JSON and you will obviously see that the 'data' Is an object and how to access it.
