纯js操作时间的方法

//格式化时间//转换日期为yyyy年mm月dd日

function dateStringFormt(v) {    if (v != "") {          try{                var dateString = v.split(" ", 1)[0].split("-");                var returnDateString = "";                if (dateString[0].length > 1) {                    returnDateString += dateString[0] + '年';                }                else {                    returnDateString += '0' + dateString[0] + '年';                }                if (dateString[1].length > 1) {                    returnDateString += dateString[1] + '月';                }                else {                    returnDateString += '0' + dateString[1] + '月';                }                if (dateString[2].length > 1) {                    returnDateString += dateString[2] + '日';                }                else {                    returnDateString += '0' + dateString[2] + '日';                }                return returnDateString;          }        catch(e)        {          return "";        }        }    else {        return "";    }
