Some of you may have heard about JQuery but aren’t sure exactly what it is or when it’s good to be used, so I would like to take a moment to explain!
What is JQuery?
JQuery is a really cool open source Javascript library that makes Javascript development slightly easier and provides tools to create hover effects and animations very easily. You can download the source here:
When should JQuery be used?
I’ve asked several people what they think of JQuery, and most of them refer to its easy notation of accessing html elements via an id using:
$(“#id”)
instead of
document.getElementById(“id”)
It makes sense! It’s so annoying coding “document.getElementById(“id”)” everywhere in your javascript scripts. The second thing people mention is that it’s great for creating image galleries or slide shows with Javascript code if you don’t want to mess with using Flash.
