【问题:】如何获得今天之前一周,或前一个月的日期呢?
一、在方法中写入以下代码:
methods: {
// 获取当前时间,day为number,getDay(-1):昨天的日期;getDay(0):今天的日期;getDay(1):明天的日期;【以此类推】
getDay(day) {
var today = new Date();
var targetday_milliseconds = today.getTime() + 1000 * 60 * 60 * 24 * day;
today.setTime(targetday_milliseconds); //注意,这行是关键代码
var tYear = today.getFullYear();
var tMonth = today.getMonth();
var tDate = today.getDate();
tMonth = this.doHandleMonth(tMonth + 1);
tDate = this.doHandleMonth(tDate);
return tYear + "-" + tMonth + "-" + tDate;
},
doHandleMonth(month) {
var m = month;
if (month.toString().length == 1) {
m = "0" + month;
}
return m;
},
},
二、测试:
created() {
console.log("昨天:", this.getDay(-1))
console.log("今天:", this.getDay(0))
console.log("明天:", this.getDay(1))
console.log("1000年以后:", this.getDay(1000 * 365))
},
效果:
