jquery 那些事儿~

var $$ = ajQuery = function(selector) {
    return new ajQuery.fn.init(selector);
}

ajQuery.fn = ajQuery.prototype = {
    name: ‘aaron‘,
    init: function(selector) {
        this.selector = selector;
        return this;
    },
    constructor: ajQuery
}

//2个构造器关联的关键
ajQuery.fn.init.prototype = ajQuery.fn         

ajQuery.fn.say = function() {
    $("#aaron").html(this.name);
}

$$().say()
