Question

我有一些对象：

var ads = [
{   
    adName: "Football Team",
    adText: ["....","...."],
    adImg: ["images/img1.png", "images/img2.png", "", "", ""],
    adPreviewLink: "templateA",
    adSeconds: 15,
    adTime: ad1Time
},{
    adName: "Basketball Team",
    adText: ["...","..."],
    adImg: ["images/img-b1.png", "images/img-b2.png", "", "", ""],
    adPreviewLink: "templateB",
    adSeconds: 10,
    adTime: ad2Time

}];

adTime属性也是一个对象：

var ad1Time = {
    hours: ["6","12"],
    day: [weekdaysEnum.monday, weekdaysEnum.wednsday],
    month: [monthEnum.march, monthEnum.april],
    year: 2016,
    daysNumber: []
}

现在我想检查adTime＆gt;＆gt;年，但我收到了错误。

未捕获的TypeError：无法读取属性＆＃39;年份＆＃39;未定义的

以下是我试图检查财产的方法：

var date = new Date();
var now_day = date.getDate();
var now_month = date.getMonth();
var now_year = date.getFullYear();

for (var i = 0; i < ads.length; i++) {
    if (ads[i].adTime.year == now_year) {
        for(var index_month; index_month < ads[i].adTime.month.length; index_month++)
        {
            if(ads[i].adTime.month[index_month] == now_month)
                console.log(ads[i].adName);
        }
    }

}

那么错误在哪里（这里的错误：ads [i] .adTime.year）？感谢。

Answer 1

您需要定义＆＃39; ad1Time＆＃39;和＆＃39; ad2Time＆＃39;之前＆＃39;广告＆＃39;。
