js 格式化时间 供页面使用

let date = new Date(1648605053000)   //后面3个零自己补上去 才是对的时间
        
        console.log(date.getFullYear());
        console.log(date.getHours());
        console.log(date.getMonth());
        console.log(date.getDate());//哪一天
        console.log(date.getDay());//星期几
        var week = ['星期天','星期一','星期二','星期三','星期四','星期五','星期六']
        //完全版
        console.log(date.getFullYear()+'-'+(date.getMonth()+1)+'-'+date.getDate()+week[date.getDay()]+'-'+date.getHours()+'点');
