You know, I never really got a good answer to that question. The "j" obviously stands for JavaScript, and I believe that the "query" part is an allusion to the way the the selectors "query" the DOM for the element to wrap with jQuery functionality.
At least that's the story I'm sticking to!
2. Is there any support for validating the field values like how regular expressions are used?
Indeed. jQuery is designed and engineered for add-ons (called plugins). There are a number of well-received validation plugins available for jQuery.
