jQuery is a fast and concise JavaScript library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development. jQuery is designed to change the way that you write JavaScript. That’s the definition from the author of jQuery. jQuery is also a cross-browser JavaScript library, which means write once and run in every browser.
There are a lot of other AJAX frameworks out there, such as Prototype, Mootools, Ext library, Google Web Toolkit (GWT), Yahoo! UI library, script.aculo.us, Dojo Toolkit, etc. But jQuery is one that is widely used and extended. I’ve known jQuery for a long time, but I haven’t paid much attention to learning it. But this week I had to learn jQuery for my project, and it is quite fun.
The first thing I learned with jQuery is using AJAX to create, update, and delete data — well known as CRUD operations. So what I made for the first time is a wall post with jQuery. It is a very simple one. You can try it here. And download the source here.
I love jQuery!
