I'll try to be a bit more clear.
There's a couple of simple rules. Whenever you include jQuery, it will
take anything already in the $ and jQuery variables and back them up
so it can install itself in the $ and jQuery variables. When you call
noConflict(true), jQuery (the version that is in the $ and jQuery
variables - i.e. the last version loaded) will take the backed up
library and put it back into the $ and jQuery variables, then return
you a pointer to itself.
If you're wanting to use two versions of jQuery as well as Prototype
on the same page, you'll need to call noConflict twice, and import
things in a certain order. I'm not sure how well this will work with
<script src="..."> blocks being loaded asynchronously (you'll need to
give it a good test) but it should work.
<script src="prototype.js"></script>
The $ function here will use prototype
<script src="jQuery114.js"></script>
jQuery loads and puts Prototype into backup variables (called _$). $
is now jQuery
<script>jq114 = jQuery.noConflict(true);</script>
The $ function is now prototype again. To use jQuery, use jq114()
instead.
This is where you're up to, if i'm understanding you correctly. now
you want to load jQuery 1.2.1
<script src="jQuery121.js"></script>
Prototype is now backed up in _$ (as it was in $ before) and jQuery
1.2.1 is in $
<script>jq121 = jQuery.noConflict(true);</script>
Prototype is now back in $ and jQuery 1.2.1 is in jq121.
So now, to use Prototype, you use the normal $(...) function. To use
jQuery 1.1.4, you use jq114(...) and to use jQuery 1.2.1 you use
jq121(...).
I've never tried loading three libraries and I'm no jQuery/Prototype/
JS pro but that might work. If not, I doubt I'll be of much use. You
might have problems loading plugins if jQuery isn't in a variable
called $ or jQuery. I've never tried so that's up to you I'm afraid.
If you can't get the code working, your best bet is probably going to
be to learn v1.1.4. Or just use 1.2.1 and get the plugin to provide
backward compatability with 1.1.4 for your Wordpress plugin. I only
jumped on board recently so I've not got much idea of what's different
between 1.1 and 1.2.
Hope this helps.
George.
