Ok, and now that I came across the need, I saw you and Michael talk
about this.
Before I discovered jQuery 3 weeks ago, I discovered the simple
"alias" trick for $ almost 7 weeks ago. :-) when we were moving ahead
with WEB 2.0 stuff and notice a small neat library was using $
function $(s) { return document.getElementById(s);}
I said "ahhhhhhh, so that is what the $ is all about!" - a short cut
for the massive common usage of document.getElementbyId(). So
started creating JS code like mad and also cleanup some older JS code
that we currently use. I even added a catch to my $ function to help
me isolate bad id references during development:
function $(s) {
var e = document.getElementById(s);
if (!e) alert("Bad element id: "+s);
return e;
}
Of course, I discovered jQuery and up to a few days ago just using it
in isolated stuff.
Now when I add some of my older $ work, I get errors.
So now I see where this "alias" replacement allows for compatibility?
I tried to use the examples, not really understanding what was
happening, and it sorta work but I ended up renaming my $(s) to
ele(s) simply because I have not officially used my own version.
But if I wanted to keep it or maybe try some other $ prototype, how
do you switch between the two?
Does that mean you have to use something else for jQuery or just use
jQuery() instead?
