1、js 获取当前日期星期几
getWeek(time) {
let weekDay = ["周日","周一", "周二", "周三", "周四", "周五", "周六"];
let myDate = new Date(Date.parse(time));
return weekDay[myDate.getDay()]
},
console.log(getWeek('2019-09-11') // 周三
2、iveiw 时间限制今天之前不可选
<Date-picker
type="date"
:options="pickerOptionsStart"
></Date-picker>
pickerOptionsStart: {
disabledDate (time) {
return time.getTime() < new Date(new Date().toLocaleDateString()).getTime();
}
}
3、js 计算某个时间 前 15天 后15天
function GetDateStr(AddDayCount, date, type) {
var dd = new Date(date);
dd.setDate(dd.getDate()+AddDayCount);
var y = dd.getFullYear();
var m = (dd.getMonth()+1)<10?"0"+(dd.getMonth()+1):(dd.getMonth()+1);
var d = dd.getDate()<10?"0"+dd.getDate():dd.getDate();
if(type){
if(date === this.oldTime) {
return '今天'
} else {
return d
}
} else {
return y + "-" + m + "-" + d;
}
}
GetDateStr(-14, '2019-09-12') // 2019-08-29
GetDateStr(14, '2019-09-12') // 2019-09-26
