Vue基于JavaScript根据日期判断是星期几

方法

getWeekDay(date){
				var week;
				if(date.getDay()==0) week="周日"
				if(date.getDay()==1) week="周一"
				if(date.getDay()==2) week="周二"
				if(date.getDay()==3) week="周三"
				if(date.getDay()==4) week="周四"
				if(date.getDay()==5) week="周五"
				if(date.getDay()==6) week="周六"
				return week;
			},

使用

//生成 周一/周二等
var handData = resp.data;
for (var i = 0; i < handData.length; i++) {
    if (i == 0) continue;

    var myDate = new Date(that.dataForm.searchTime);
    myDate = myDate.getFullYear() + "-" + (myDate.getMonth() + 1);
    console.log(myDate) var dateStr = myDate + "-" + i;
    var weekStr = that.getWeekDay(new Date(dateStr));
    handData[i].key = handData[i].key + "\n\n\n\n\n" + weekStr;
}

that.tableList = handData;

效果
