javascript - AJAX request returns 200OK but fails despite return data being JSON -

edit: in case, the reason not returning correct information trying use jsonp connect cors data setup, whereas server did not have set particular computers access. needed talk , adjust permissions of config file server. thats going on, , couldnt figure out because thought cors , jsonp synonymous, in fact there different ways carried out , server permissions need set.

brief: have $.ajax request pings server looking data. fails, data shows success.

going network, shows response. want it. right out of grasp.

errors: says fails, return is:

{"readystate":4,"status":200,"statustext":"success"} 

so, means somewhere on client side, flagged. response is:

edit: ajax request:

var u = "myusername"; var p = "mypass"; var = u + ":" + p; $.ajax({     type: "get",     url: "http://xx.xxx.xx.x/mas3/datasources/inspecttech.inspecttech/schema/classes/",     contenttype: "application/json; charset=utf-8",     datatype: "jsonp",     headers: {authorization: "basic "+up},     success: function (r) {         alert("success: " + json.stringify(r));     },     error: function (r) {         alert("failure: " + json.stringify(r));     } }); 

the response is:

content-type:application/json ["asset","assetelementdefmap",…,"workingset"] 

that's no jsonp script, plain json (the "padding", ie. callback function, missing). since request cross-domain, you're not allowed access - , executing script fails when resource loads 200 ok status.
