Date对象-练习

编写代码，将当前日期按“2017-12-27 11:11 星期三”格式输出

1. 实现方式一: switch结构实现

function myDateFor1() {
    let nowTime = new Date();
    let minutes = nowTime.getMinutes();
    minutes = minutes < 10 ? '0' + minutes : minutes;
    let dateFor = `${nowTime.getFullYear()}-${nowTime.getMonth() + 1}-${nowTime.getDate()} ${nowTime.getHours()}:${minutes} `;
    switch (nowTime.getDay()) {
        case 0:
            console.log(dateFor+'星期一');
            day = '';
            break;
        case 1:
            console.log(dateFor+'星期二');
            break;
        case 2:
            console.log(dateFor+'星期三');
            break;
        case 3:
            console.log(dateFor+'星期四');
            break;
        case 4:
            console.log(dateFor+'星期五');
            break;
        case 5:
            console.log(dateFor+'星期六');
            break;
        case 6:
            console.log(dateFor+'星期日');
            break;
        default:
            console.log('星期输入不对哦!');
    }
}

2. 实现方式二: 数组索引取值

function myDateFor() {
    let days = ['星期一', '星期二', '星期三', '星期四', '星期五', '星期六', '星期日'];
    let nowTime = new Date();
    let minutes = nowTime.getMinutes();
    minutes = minutes < 10 ? '0' + minutes : minutes;
    let day = nowTime.getDay();
    day = days[day];

    console.log(`${nowTime.getFullYear()}-${nowTime.getMonth()}-${nowTime.getDate()} ${nowTime.getHours()}:${minutes} ${day}`);
}

myDateFor();
