JSON model and OData model

[#1]

Hi all,

I have a question.

What's the diff between JSON model and Odata model(JSON format).

If I need a JSON model from back-end, can I just use JQuery/AJAX instead of using UI5 OData APIs?

If you need to use plain JSON data from backend you will not be able to use odata model as there is no metadata.

in case of odata with json format ($format=JSON) you can use jquery ajax, you just have to explicitly handle xsrf token

Hi,

the two models have different features when it comes to data handling. The JSONModel is better for client-side data container, because you can very easily add, remove entrys. The ODataModel has nice features when it comes to data transfer between the client and server. Based on the binding you make to a control, it makes automatic requests to the server for getting data. You can also add filters, expand deep entities, etc. I suggest you take a look at the APIs of the two models.

Yes, you can also use JQuery/AJAX,like this:

 jQuery.ajax({ 
   type :'POST', 
   url : yourURL,
   headers : oHeaders,
   cache : false, 
   contentType : yourContectType,
   processData : false, 
   data : yourDataObject,
   success : _handleSuccess,
   error : _handleError, 
   });
