Question

I was previously using the jQuery autosave plugin but have recently removed it. Some code is still trying to use this function, so how can I temporarily extend the jQuery object so there is an empty function to prevent errors until I can get through all of the code that is trying to use the function?

The plugin is called in this way:

jQuery().autosave.restore();
jQuery().autosave.save();

I think those are the only two functions that exist, so it would be OK to create two empty functions, but is there a way to create a catch-all function on this type of object?

Note

This is a temporary solution until I can go through a lot of code. I do believe the question is a valid coding question even if you think this workaround is not ideal (it isn’t).

There is a way to do this. You can create a dummy plugin (check out jQuery’s documentation for creating plugins):

(function( $ ){

  $.fn.autosave = {
       restore: function() {};
       save: function() {};
  };
})( jQuery );

I would highly recommend against doing this, however. Instead, you should look at those errors and fix them, i.e., stop your code from using them. Otherwise you’re simply hiding the problem.
