Guys,
I was looking the code for the getScript() function and I saw that
when the javascript (text) file is received you "eval()"uate it, thus
executing what is inside. This seems to be a rather common way of
loading javascript since I have seen it in other frameworks as well.
Still, I've been using another approach that seems to work fine (at
least) in FF and IE. Insted of getting the file and evaluating it, I
just add a new SCRIPT element to the HEAD of the document with the
specified URL. The main difference with this is that I can check if
that script was already loaded (maybe by another component) and thus
avoid loading it twice.
(something like this:
[code]
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = uri;
document.getElementsByTagName('head')[0].appendChild(script);
[/code]
(Of course I am not checking for anything, but just to clarify)
I am pretty sure that there is a good reason why to use eval instead
of my approach, but I just wanted to know why.
Cheers
AB
