How can I return a variable from a $.getJSON function

Question

I want to return StudentId to use elsewhere outside of the scope of the $.getJSON()

j.getJSON(url, data, function(result)
         


        

Answer 1

Even simpler than all the above. As explained earlier $.getJSON executes async which causes the problem. Instead of refactoring all your code to the $.ajax method just insert the following in the top of your main .js file to disable the async behaviour:

 $.ajaxSetup({
   async: false
 });

good luck!
