JS获取当前日期的前七天的日期

// 获取当前日期
var currentDate = new Date();

// 获取前七天的日期
var previousDates = [];
for (var i = 6; i >= 0; i--) {
  var previousDate = new Date(currentDate);
  previousDate.setDate(currentDate.getDate() - i);
  previousDates.push(previousDate);
}

// 格式化日期
var formattedDates = previousDates.map(function(date) {
  var year = date.getFullYear();
  var month = (date.getMonth() + 1).toString().padStart(2, '0');
  var day = date.getDate().toString().padStart(2, '0');
  return year + '-' + month + '-' + day;
});

console.log(formattedDates); // 输出前七天的日期数组
