字符串转日期

//字符串转日期格式，strDate要转为日期格式的字符串

function getDate(strDate){

  var date = eval('new Date(' + strDate.replace(/\d+(?=-[^-]+$)/, 

   function (a) { return parseInt(a, 10) - 1; }).match(/\d+/g) + ')');

  return date;
}

//测试

alert(getDate("2012-05-09"));

// 字符串转时间

    getDateFromString(strDate){

        let str = strDate.replace(/-/g, '/');
        var date = new Date(str)
        return date
    },

//根据日期字符串获取当周周一周日时间

getWeekDateFromString(e) {
        let date = this.getDateFromString(e)
        let today = date.getDay()
        if (today == 0) {
            today = 7
        }
        let dateInve = date.getTime()
        let dateStart = this.formatDate(new Date(dateInve - 86400 * (today - 0 - 1) * 1000), 'yyyy-MM-dd')

        let dateEnd = this.formatDate(new Date(dateInve - 86400 * (today - 6 - 1) * 1000), 'yyyy-MM-dd')

        console.log("week:", dateStart, dateEnd)
    },
