Question

I have the following code:

$.get(viewUrl + para, function (data) {
    dialogDiv.html(data);
    ...
});

Is there some way that I can add an error check to this? Something that will call a function if the get fails?

Answer 1

As $.get() is shorthand for the $.ajax() method, you could just use that:

$.ajax({
  url: viewUrl + para,
  success: function (data) {
    dialogDiv.html(data);
   ...
  },
  error: function() {
    alert("Error!");
  }
});

I recommend this option as it (for me at least) seems far better suited for more complex AJAX requests. Sure adding an error callback may not constitute it being complex, but it’s good to know your options.
