Alert might not work by one of the following reasons:
  • data.items is empty; then the function in the $.each loop is never called;
  • data is undefined; then the exception is thrown when you try to dereference it by getting data.items; so the rest of the script's call stack is skipped; note that unhandled exceptions are not shown;
  • the function in the loop is called but exception is thrown inside it.
To find out which case takes place you can use the step-by-step debugging or handle exceptions and provide test output.
