[jQuery] Changing scope of a function

[jQuery] Changing scope of a function


Hello all,
I'm running into a few problems with a plug-in I'm developing. What I
would like to do is to take a function (which is in any old scope,
global for example) and then execute it in the scope of my plug-in. I
rather thought I would be able to do something like in my constructor:
    this.fnTest = fnGlobalTest;
This would take a reference of the global function and store it in my
object. It is just a reference being stored, so it looks like it is
then being executed in the original scope. So I tried:
    this.fnTest = function() { fnGlobalTest.call( this ); };
Expecting that to work - it didn't. I can't access any of the private
functions. Indeed the only way I have managed to do this is to:
    this.fnTest = eval( '('+ fnGlobalTest.toString()+')' );
Which is obviously far from ideal...
Does anyone have any suggestions for how I might do this?
Regards,
Allan
