问在Zapier中使用Javascript从日期中减去天数

EN

var date = new Date(input.date-zap),
formatted, daysToSubtract;

switch (moment(date).day()) {
    // Saturday = 1 days
    case 6:
    daysToSubtract = 3;
    break;
    // Monday = 3 days
    case 1:
    daysToSubtract = 3;
    break;
    // Tuesday = 4 days
    case 2:
    daysToSubtract = 4;
    break;
    // Subtract 2 days otherwise.
    default:
    daysToSubtract = 2;
    break;
}
