jQuery’s project as a JavaScript library is straightforward — it strives to make the lives of net builders more uncomplicated by way of patching over definite parts of cross-browser improvement and by way of making different projects quite often wanted through builders a lot more straightforward. jQuery has the genuine, confirmed skill to lessen many traces of plain-vanilla JavaScript to simply a couple of traces, and, in lots of circumstances, only a unmarried line. jQuery strives to take away limitations to JavaScript improvement by means of elimination redundancy at any place attainable and normalizing cross-browser JavaScript improvement in key components the place browsers may another way vary, resembling Microsoft’s occasion API and the W3C occasion API, and different, extra remedial initiatives like getting the mouse cursor’s place while an occasion has taken place.

jQuery is a compact, light-weight library that presently works in Microsoft’s web Explorer browser from model 6 on, Firefox from model 1.5 on, Safari from model 2.0.2 on, Opera from model nine on, and Google’s new Chrome browser from model 0.2 on.

Another widget that jQuery UI presents is a graphical slider bar, just like your media player’s quantity control.

As jQuery has performed for JavaScript programming in most cases, jQuery UI strives to do for redundant graphical consumer interface (GUI) initiatives. jQuery UI can provide the facility to make specialist user-interface widgets with less improvement effort.
