JSON request code // make sure that callBackURL is a javascript variable set from ajaxSaveBehaviour.getCallbackUrl().toString(); // console.log(" call back url :"\+ callBackURL); $.ajax({ url: callBackURL, $.ajax({ url: callBackURL, type: 'post', cache: false, cache: false, data:JSON.stringify(ccbArry), // ccbArry is my json array contentType: 'application/json; charset=utf-8', dataType: 'json', success: function(json) { console.log(" reponse :"\+ json); }, }, error: function (XMLHttpRequest, textStatus, errorThrown) { console.log("error :"+XMLHttpRequest.responseText); } }); // the follwoing code handles ajax json request from jQuery } }); |
This section of code is an abstract ajax behavior which accepts a json document in request and responds with another json document that is then available to the javascript method on the page.
