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

Edit: In my case, The the reason that it was not returning to correct information is that I was trying to use JSONP to connect to a CORS data setup, whereas the server did not have it set up for my particular computers access. I needed to talk to someone and adjust the permissions of the config file for the server. Thats what was really going on, and i couldnt figure it out because i thought CORS and JSONP were synonymous, but in fact there are different ways they are carried out and certain server permissions which need to be set.

Brief: I have an $.ajax request which pings a server looking data. It fails, but data shows success.

Going into the Network, it SHOWS the response. I want it. Its right out of my grasp.

Errors: Says it fails, but the return is:

{"readyState":4,"status":200,"statusText":"success"}

So, it means that somewhere on the client side, it was flagged. The response is:

["Asset","AssetElementDefMap","AssetFile","AssetFileCategory","AssetFileCategoryObjectMap","AssetFilesFieldMap","AssetFilesReportMap","AssetTree","AssetType","BicUrl","CancelledUpload","CurrentValue","DataTypeInstanceMembers","DataTypeInstances","DataTypeMembers","DeviceDatabase","ElementDef","ElementDefEnvironment","ElementDefFormMap","ElementDefManual","ElementDefStructUnit","ElementDefStructUnitList","Field","FieldChoice","FieldFormScriptMap","FileType","FileTypeAssetFileCategoryMap","ForgotPassword","Form","FormScriptFunction","FormType","in_id","InspectionType","Inspector","MobileFormOSMap","MobileReportTypeFormMap","MobileReportTypeFormTypeMap","ProfileProperty","Report","ReportSubAssetMap","ReportType","ReportTypeAssetTypeMap","ReportTypeInspectionTypeMap","ReportValue","WorkingSet"]

The response is:

Content-Type:application/json
["Asset","AssetElementDefMap",…,"WorkingSet"]

That's no JSONP script, but plain JSON (the "padding", ie. the callback function, is missing). Since the request is cross-domain, you're not allowed to access it - and executing it as a script fails even when the resource loads with a 200 OK status.
