party_bid 项目之 重构
function bid_result(priceLists,priceNumber){ var count = _.chain(priceLists) .sortBy("price") .groupBy(function(price){ return price.price; }) _.map(count._wrapped, function (value,key) { priceNumber.push({'price': key, 'number': value.length,'value':value}); }) save_localStorage("localStorage_bid_results",priceNumber);}function get_result(bid_results){ return _.find(bid_results,function(list) { return list.number == 1; });}

?2.面向对象编程

? javascript语言是基于原型的面向对象方式，对象依靠构造器（constructor）利用原型（prototype）构造出来的。在对数据进行增删改查等操作时，可以通过调用对象实例的方法来实现具体的操作，从而可以节省数据间的传送。??

function Activity(put){    this.title = put,    this.disabled = false,    this.color = "",    this.bid=0}//saveActivity.prototype.save = function () {    var list = Activity.get_activities();    list.unshift(this);    save_localStorage("localEventsLists",list);}Activity.get_activities = function () {    return JSON.parse(localStorage.getItem("localEventsLists")) || [];};
