做项目时遇到需求，需要获取当前时间后一星期的时间，直接上代码

放在methods里面，getdate方法可以在created里执行，也可以按需执行

    getdate() {var currentTime = new Date();var nowDayOfWeek = currentTime.getDay(); //当前周的第几天var nowDay = currentTime.getDate() + 1; //获取明天var nowMonth = currentTime.getMonth(); //当前月var nowYear = currentTime.getFullYear(); //当前年currentTime = new Date(nowYear, nowMonth, nowDay - nowDayOfWeek + 1); //完整日期//定义一个数组var arr = [];for (var i = 0; i < 7; i++) {if (i == 0) {currentTime = currentTime.setDate(currentTime.getDate());} else {currentTime = currentTime.setDate(currentTime.getDate() + 1);}currentTime = new Date(currentTime);var currentYear = currentTime.getFullYear();var currentDays = currentTime.getDate();var currentMon = currentTime.getMonth() + 1;var dateDay = currentDays; //某一天var dates = {};dates.LaterDay = currentYear + "-" + currentMon + "-" + dateDay;//将一星期后的日期通过for循环存到数组当中去arr.push(dates);}console.log("打印数组里的日期", arr);},
 

用点击事件也可以触发改方法

    查询当下时间
 

显示结果，执行时间是2022-9-12，可以看到一星期后的日期数据成功打印
