The reason that doesn't work is that the $(theFunction) code has already
saved a reference to the actual function object for theFunction. When you
later replace the *name* theFunction with a different function object, it
has no effect on that existing reference. It still points to the original
function.
BTW, a simpler way to say window['theFunction'] is window.theFunction -
means the same thing either way.
Can you insert a script after jQuery is loaded but before the file in
question is loaded? If so, you could do something like this:
if( $ != jQuery )
alert( 'I made a bad assumption!' );
$ = function( a ) {
if( a == theFunction )
$ = jQuery; // ignore call and restore original $
else
return jQuery.apply( this, arguments ); // allow other calls
};
Or perhaps a better way to code it is:
(function() {
var old$ = $;
$ = function( a ) {
if( a == theFunction )
$ = old$; // ignore call and restore original $
else
return old$.apply( this, arguments ); // allow other calls
};
})();
The second version avoids relying on the fact that $ is an alias for jQuery
- so it's a more general pattern that you could use in any similar
situation.
Either way, by loading this code before the other script, you redefine $ so
it ignores the $(theFunction) call and then restores the original $ for
efficiency.
