i know jquery like manipulating the data and so but confused with the jquery plugins. how to use them is always a confusing thing for me so how to learn and use them?
jQuery provides a very convenient way to extend the library, so anyone can write a plugin. This is very cool, but naturally this also means that these plugins can vary heavily in quality and documentation; all you can do is read through the API, give it a shot and see if it works for you.
That said, most of them basically work the same way: do something on the current jQuery object (i.e. a set of DOM elements). It might be helpful to read through the plugin section in the jQuery learning center; if you can write a basic plugin yourself, you’ll have a better understanding of how other plugins work.
jQuery is a library (a collection) of JavaScript functions which as m3g4p0p posted can be extended.
Perhaps you are having trouble understanding dependencies?
For example, if a plugin relies on jquery-ui functions, since jquery-ui relies on core jquery functions you need to load each eg. (in butchered pseudo-html)
<link "jquery">
<link "jquery-ui">
<link "plugin">
You can then use the plugin’s functions - typically before the </body> tag after the DOM has loaded in.
I imagine the quality of documentation each plugin has varies, so having a good grasp of JavaScript will go far in letting you know what each plugin does and how to use them.
