JS获取当前时间并格式化

// 获取当前时间
      getCurrentTime(){
        //创建对象
        let date = new Date();
        //获取年份
        let y = date.getFullYear();
        //获取月份  返回0-11
        let m =date.getMonth()+1;
        // 获取日
        let d = date.getDate();
        //获取星期几  返回0-6   (0=星期天)
        let w = date.getDay();
        //星期几
        let ww = ' 星期'+'日一二三四五六'.charAt(date.getDay()) ;
        //时
        let h = date.getHours();
        //分
        let minute = date.getMinutes()
        //秒
        let s = date.getSeconds();
        //毫秒
        let sss = date.getMilliseconds() ;

        if(m<10){
          m = "0"+m;
        }
        if(d<10){
          d = "0"+d;
        }
        if(h<10){
          h = "0"+h;
        }
        if(minute<10){
