I have three async ajax calls functions with callback functions for fetching info to the main page. Those functions are on another js file.

Ajax_GetUsers(Fetch_Users);
Ajax_GetContactTypes(Fetch_ContactTypes);
Ajax_GetCasePriorities(Fetch_CasePriorities);

After those three finish fetching the results i want to do one more call to this function :

Ajax_GetCaseData(selectedCaseId, Fetch_CaseData)

This is the code i created but still does not work . The Ajax_GetCaseData sometimes is called before the others . How can i make sure that the Ajax_GetCaseData will be always executed after the other three asynchronous functions : Here is my Code :

$.when(Ajax_GetUsers(Fetch_Users),Ajax_GetContactTypes(Fetch_ContactTypes), 
       Ajax_GetCasePriorities(Fetch_CasePriorities))                        
 .then(function () {
      Ajax_GetCaseData(selectedCaseId, Fetch_CaseData);
});

You can't just work with callbacks as promises. – Jonas Wilms Apr 23 '19 at 07:31
