As Norbert just pointed out in the thread "Dynamically Loaded Scripts
in IE 7 - Problems Found and Lessons Learned", it is a scope issue.
If the functions in your script file loaded via getScript use either
of the following two methods (they're synonymous) then the functions
will not be available in the global scope.
function myFunc(){}
var myFunc = function(){}
However, if you define functions like this:
myFunc = function(){} // note the lack of "var"
Then it will be available and work fine. I've found no fix for this
in jQuery source. For now we just have to be careful of the scripts we
load in.
You can also keep using the first method above and just define the
variable in the global scope earlier in the script file like so:
myFunc = myOtherFunc = {};
function myFunc(){}
etc...
This was tested against SVN jQuery and IE7.
