How does js get the points in years, months, days, minutes and seconds?

1. First, open an html editor and create a new html file, such as index.html.

2. In index.html

var a = new Date()； document.body.innerHTML？

= ' when:'+a . get hours()+' < br/& gt； points:'+a . get minutes()+' < br/& gt； Seconds: "+a.getseconds ();

3. The browser runs the index.html page. At this point, js gets and prints every minute of the current time.
