禁用本周以外的日期

本节目标：理解“禁用本周以外的日期”的核心思路，并能把它用于实际开发或面试表达。 pickerOptions() { const now = new Date(); let startDay = now.getDay(); let startOfWeek = new Date(now); startOfWeek.setDate(now.getDate() - startDay + 1); // 获取周一 startOfWeek.setHours(0, 0, 0, 0); // 设置为当天的00:00:00 let endOfWeek = new Date(now); endOfWeek.setDate(now.getDate() + (7 - startDay)); // 获取周日 endOfWeek.setHours(23, 59, 59, 999); // 设置为当天的23:59:59 const disabledDate = (time) => { return ( time.getTime() < startOfWeek.getTime() || time.getTime() > endOfWeek.getTime() ); }; return { firstDayOfWeek: 1, disabledDate }; },
