How to use jquery with other js frameworks like YUI, mootools, prototype etc?

[Mike Kypriotis]

I am creating a program written in JS and need to import data from an external JSON file, and saw that jquery can do it much easier, thing is should I force someone who wants to use it in his site to include jquery just for a little bit of extra functionality? And what if he is already using something else like YUI, won't there be a conflict? I assume that all do about the same things.

P.S. JSON or XML which would you use?

jQuery is so prevalent these days that it's probable they're already using it.

See this to eliminate conflicts:
http://docs.jquery.com/Using_jQuery_...ther_Libraries

I guess you could write the code using the different frameworks if you're really concerned.

Or, you could use Douglas Crockford's (the js guru) JSON library(s).

See:
https://github.com/douglascrockford/JSON-js
And:
http://www.json.org/js.html (his original article)

I've use it a few times when I didn't want to use a framework.

JSON vs. XML?
It depends!
See:
http://www.json.org/xml.html

The owner of the site will upload the JSON file (it is a way not to force him to down/upload the js file when data needs to be changed) so it is trusted do I need a parser? Also at
https://github.com/douglascrockford/JSON-js
which file did you use for support on both legacy and modern browsers.
Basically I need a routine which reads the JSON, checks its structure (the writer may have missed a character) and inform of possible invalid format and then gives me the data -which I can then further check with regular expressions (to be precise the program is a banner rotator so for every banner/object I will need 4 attributes: a filename, a url, how much it will show and if it will be shown at all -in other words a flag ), can I do these with JSON (with what I have read it seems the best choice)?
