jquery学习笔记

Lets go one step back before continuing: jQuery is a lot about making code shorter and therefore easier to read and maintain. The following is a shortcut for the $(document).ready(callback) notation:

 $(function() {
   // code to execute when the DOM is ready
 });

Plug me: Writing your own plugins

Writing your own plugins for jQuery is quite easy. If you stick to the following rules, it is easy for others to integrate your plugin, too.

Plugin Naming

Find a name for your plugin, lets call our example "foobar". Create a file named jquery.[yourpluginname].js, eg. jquery.foobar.js

Adding a Custom Method

Create one or more plugin methods by extending the jQuery object, eg.:

 jQuery.fn.foobar = function() {
   // do something
 };

Which will then be accessible by performing:

 $(...).foobar();
