JQuery is one of the most important javascript framework I used, besides default jquery apis, I use a lot of jquery plugins to improve the web interactive, such as auto complete, dropdown menu, chart and so on.
I will be likely to write some jquery plugins or hack others' jquery plugins, The following is the template for a jquery plugin that I learned from "jQuery 1.4 Plugin Development"
(function($) {
$.fn.pluginName = function(options) {
var defaults = {
......
}
var o = $.extend({}, defaults, options);
return this.each(function() {
var e = $(this);
......
});
}
})(jQuery);
the structure (function($) {...})(jQuery) can protected the conflict
of $ sign which is used by other javascript framework.
$.extend({}, defaults, options) provides a flexible way to tweak your
plugin, options can override defaults, but not change the value of
defaults.
return this.each(function() {...}) promises your plugin functions are
chainable, like the default jquery apis.
