JS关于根据当前时间计算一周的方法

var start = new Date();

var end = new Date();

var date = new Date();

var day = date.getDay() - 1;

// 因为星期天为0

if (day == -1) {

day = 6;

}

for (var index = 0; index < day; index++) {

start = start.add(Date.DAY, -1);

}

for (var index = 6; index > day; index--) {

end = end.add(Date.DAY, 1);

}
