Javascript change getHours to 2 digit
提问by ngplayground
If the hour is less than 10 hours the hours are usually placed in single digit form.
如果小时数少于 10 小时，则小时数通常以个位数形式放置。
var currentHours = currentTime.getHours ( );
Is the following the only best way to get the hours to display as 09instead of 9?
以下是让小时显示为09而不是的唯一最佳方法9吗？
if (currentHours < 10) currentHours = '0'+currentHours;

Your's method is good. Also take a note of it
你的方法很好。也记下它
var date = new Date();
currentHours = date.getHours();
currentHours = ("0" + currentHours).slice(-2);

You can do this using below code,
您可以使用以下代码执行此操作，
create function,
创建函数，
function addZeroBefore(n) {
return (n < 10 ? '0' : '') + n;
}
and then use it as below,
然后如下使用它，
c = addZeroBefore(deg);

You can't do much better. Maybe you'll like:
你不能做得更好。也许你会喜欢：
var currentHours = ('0'+currentTime.getHours()).substr(-2);
