How to get controller/model/store/view in Ajax callback - ajax

Question

folks,
I am working on a project using EXTJS MVC framework for backend development.
Now I am in trouble to get controller/model/store in the Ajax callback
Here is the snippet of my code. I am in the controller to call Ajax.
Ext.Ajax.request({
url: 'http://localhost:8080/gdltest/gdl_service.cgi',
jsonData: jRequest,
method: 'POST',
success: function (response,options) {
var jsonData = Ext.JSON.decode(response.responseText);
var jData = jsonData.results.data;
When i get the data from the response, I want to get the controller/model/store to do more actions, but i don't know how to get them :(
Thank you very much for your help :)

What you've done in the success function is correct. Please check the reponse that you're getting back from the server. Also, is the url correct? Usually the relative path to the resource is given, not the absolute path, as you've given here. Is the request reaching the server? If it is I think there is an issue with the data which is being sent back. You should also use the safe option during development. The safe option throws an error if the Json returned from the server isn't in the proper format. From the docs:
decode( String json, [Boolean safe] )
safe : Whether to return null or throw an exception if the JSON is
invalid.
EDIT: If you want to use the this operator inside the success callback then specify the scope config. Example below:
Ext.Ajax.request({
url: 'http://localhost:8080/gdltest/gdl_service.cgi',
jsonData: jRequest,
method: 'POST',
success: function (response,options) {
var jsonData = Ext.JSON.decode(response.responseText);
var jData = jsonData.results.data;
},
scope : this //this will be the object form which the Ajax.request is called, and not Ajax.request itself or you can specify any other object you desire.
