I have a JavaScript function which is not firing in order. It fires the CheckForAddRecordsToAddFromDSS method, then the if (check1 || check2) statement before even firing the CheckForMissingRecordsFromSupp method.



Why is this happening?



$.getJSON("/Home/CheckForMissingRecordsFromSupp", function (data) 
check1 = data;
).done($.getJSON("/Home/CheckForAddRecordsToAddFromDSS", function (data)
check2 = data;
).done(function () )
);

          Why is this happening?




          .done expects to be passed a function. You are passing the return value of $.getJSON which is not a function.



          Consider the following example:



          foo(bar())


          Even without knowing anything about foo or bar, we definitely know that bar is executed before foo and bar's return value is passed to foo.



          Your code should be:



          $.getJSON("/Home/CheckForMissingRecordsFromSupp", function(data) 
          check1 = data;
          ).done(function() // <- function
          $.getJSON("/Home/CheckForAddRecordsToAddFromDSS", function(data)
          check2 = data;
          ).done(function() check2)
          location.reload();

          );
          );


          Having said that, since .done also receives the network response, you don't need to pass a callback to $.getJSON. You can just write:



          $.getJSON("/Home/CheckForMissingRecordsFromSupp").done(function(check1) 
          $.getJSON("/Home/CheckForAddRecordsToAddFromDSS").done(function(check2) check2)
          location.reload();

          );
          );
