利用原型写js插件

Code:

(function($){

function NAME(elm,options,index){
    var _this = this;
    this.$e = $(elm);
    this.opts = options;
    this.init();
}

NAME.prototype = {
    init : function(){},
    event : function(){}
}

$.fn.Name = function(options){
    var opts = $.extend({},$.fn.Name.defaults,options);
    return this.each(function(index){
        this.Name = new NAME(this,opts,index);
    });
}

$.fn.Name.defaults = {
    //默认参数
}

})(jQuery);
