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"
    }
]

var obj = {};//重新封装对象
for (var i = 0; i < arr.length; i++) {
    var item = arr[i];//item
    if (!obj[item[\'date\']]) {
        var _arr = [];
        _arr.push(item);
        obj[item["date"]] = _arr;
    } else {
        obj[item["date"]].push(item);
    }
}
console.log(obj)
//对象的遍历
for (var key in obj) {
    console.log(obj[key]);
}

var tab = {aa: 11111};
//console.log(tab.aa);
//console.log(tab[\'aa\']);
