day54 作业

编写代码，将当前日期按“2017-12-27 11:11 星期三”格式输出(提示:switch结构)

var date = new Date()
ymd = data.toLocaleString().split(' ')
a = ymd[0]
a = a.split('/').join('-')
b = date.getHours()+':'+date.getMinutes()
day = date.getDay()
switch(day){
    case 1:
        day = '星期一';
        break;
    case 2:
        day = '星期二';
        break;
    case 3:
        day = '星期三';
        break;
    case 4:
        day = '星期四';
        break;
    case 5:
        day = '星期五';
        break;
    case 6:
        day = '星期六';
        break;
    case 7:
        day = '星期七';
        break;
}
new_day = a+' '+b+' '+day
