js数据封装处理，将参数中相同的数据分为一类

var arr = [

    {

        id: "1",

        date: "2018-07-27",

        time: "10:00-12:00",

        schedule: "开幕式"

    },

    {

        id: "2",

        date: "2018-07-27",

        time: "12:00-14:00",

        schedule: "世界杯||今日看点||法国队"

    },

    {

        id: "3",

        date: "2018-07-28",

        time: "10:00-12:00",

        schedule: "奥尼尔"

    }, {

        id: "4",

        date: "2018-07-28",

        time: "15:00-17:00",

        schedule: "阿拉巴||巴西||俄罗斯"

    }
