根据系统当前日期获取上周时间段

Posted 2020-10-11

//获取系统当前时间
var now = new Date(); //当前日期
var nowDayOfWeek = now.getDay(); //今天本周的第几天
var nowDay = now.getDate(); //当前日
var nowMonth = now.getMonth(); //当前月
var nowYear = now.getYear(); //当前年
nowYear += (nowYear < 2000) ? 1900 : 0; //
//格式化日期：yyyy-MM-dd
function formatDate(date) {
var myyear = date.getFullYear();
var mymonth = date.getMonth()+1;
var myweekday = date.getDate();

if(mymonth < 10){
mymonth = "0" + mymonth;
}
if(myweekday < 10){
myweekday = "0" + myweekday;
}
return (myyear+"-"+mymonth + "-" + myweekday);
}

//获取上周时间
$(function(){
$(".upWeek").click(function(){

$(".downWeek").removeAttr(‘disabled‘)
$(".downWeek").css("background-color", "#3389E4")
//获取值
var getUpWeekStartDate_1 = new Date(nowYear, nowMonth, nowDay - nowDayOfWeek -6);

//给获取到的值进行格式化
var getUpWeekStartDate_1 = formatDate(getUpWeekStartDate_1);

//给value赋值
//星期一上午
$(".time_0").val(getUpWeekStartDate_1);

//禁用上周标签
$(".upWeek").attr("disabled", true)
$(".upWeek").css("background-color", "Gray")

})
})
