获取对象数组中对象属性的值

Get value of object property inside array of objects

我有一个对象数组：

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>>年，但我得到了一个错误。

未捕获的类型错误：无法读取未定义的属性"year"

以下是我如何尝试检查属性：

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);
        }
    }
}

那么错误在哪里呢？谢谢

您需要在"ads"之前定义"ad1Time"answers"ad2Time"。
