Question

Is it possible in $.getScript() to create a condition where if the first js script fails to load – for whatever reason – then run the second js? Like a backup?

Any way to make this work with jQuery 1.2 and/or 1.4?

Thanks a lot!

As long as you’re using jQuery 1.5 or greater then $.getScript() returns a Promise so you can attach a function to both success and failure. They show an example in their documentation where they attach to fail like so:

$.getScript("ajax/test.js")
.done(function(script, textStatus) {
  console.log( textStatus );
})
.fail(function(jqxhr, settings, exception) {
  $( "div.log" ).text( "Triggered ajaxError handler." );
});

There’s no reason why you couldn’t do another $.getScript() within the function that .fail() calls.
