js date格式化yyyy-mm-dd hh:mm:ss

要将JavaScript中的日期格式化为yyyy-MM-dd hh:mm:ss，可以使用以下代码：

var date = new Date();
var formattedDate = date.getFullYear() + '-' +
    ('0' + (date.getMonth() + 1)).slice(-2) + '-' +
    ('0' + date.getDate()).slice(-2) + ' ' +
    ('0' + date.getHours()).slice(-2) + ':' +
    ('0' + date.getMinutes()).slice(-2) + ':' +
    ('0' + date.getSeconds()).slice(-2);
console.log(formattedDate);

这段代码首先获取当前的日期对象 `date`，然后根据需要的格式使用 `getFullYear()`、`getMonth()`、`getDate()`、`getHours()`、`getMinutes()`和 `getSeconds()` 方法获取日期的年、月、日、时、分和秒，并使用字符串拼接的方式将它们连接起来，最后输出结果。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
