推荐答案

要计算前一天的日期，您可以使用 Date.prototype.setDate（）

To calculate the date for one day ahead you can use Date.prototype.setDate()

所以要计算从今天到前一周的所有日期，您可以这样做：

So to calculate all dates from today and week ahead, you can do something like this:

var currentDate = new Date();
var stringDate = [];

for (var i = 0; i < 7; ++i) {
    currentDate.setDate(currentDate.getDate() + 1);
    stringDate[i] = currentDate.getUTCDate() + "/" + (currentDate.getMonth() + 1) + "/" + currentDate.getFullYear();
}

console.log(stringDate);

// 0: "28/7/2015"
// 1: "29/7/2015"
// 2: "30/7/2015"
// 3: "31/7/2015"
// 4: "1/8/2015"
// 5: "2/8/2015"
// 6: "3/8/2015"
