Class-level plug-in development, which is primarily defined as a global method in jquery://The first way of writing jquery.myfunc = function (str) {    alert ("define method directly in jquery", str)}//call mode  $. MyFunc ("hello!"); /second notation Jquery.extend ({    myfunc:function (str) {        alert ("Extend extension $ method", str)    }})//Call Way  $.myfunc (" Hello! "); /third: In order to not pollute the global, mount an object as a namespace, all the custom methods are put here to ensure that jquery is globally secure. jquery.define={    myfunc:function (str) {        alert ("notation for Namespaces", str)    }}//called: $.define.myfunc ("Hello");// The above three kinds is the level plug-in development way, is not commonly used, from the invocation way to see, they are the global execution, does not need to bind the node object. Object level plug-in development: there is a canonical template; (function ($) {    $.fn.plugin = function (options) {        var defaults = {            //various default parameters        }        var options = $.extend (defaults,options);//The passed parameter overrides the default parameter        This.each (function () {            var _this = $ (this);  Cache the node objects that the plugin passes in.            //execute Content                                })        return $ (this);   Returns the Node object in order to support chained calls.    }}) (jQuery);//Call Way $ ("selector"). Plugin ({    //custom parameters, JSON format})
