Whats a problem?

Question

function printDate() {
var d = new Date();
var year = d.getFullYear();
var month = d.getMonth();
var day = d.getDay();
var print = document.write(year+"."+month+"."+day+" ");
}
// year.month.day
function printTime() {
var d = new Date();
var hours = d.getHours();
var mins = d.getMinutes();
var secs = d.getSeconds();
var printall = document.write(hours+":"+mins+"."+secs);
}
// hour:min.sec
printDate(print)
printTime(printall)
setInterval(printTime, 1000);
setInterval(printDate, 1000);
At the end prints a error at line 17 , why printall doesnt work?

Answer 1

You need to make them global by declaring them outside the function definitions. Just put

var print, printall;

at the start of your code.

Answer 2

In your code, printall is a local variable which can be accessed only inside printTime function.

Answer 3

I don't know 😁 I'm also learning JavaScript. I can just say that there is no need of those functions. 😁

Make a function named clock() and place the whole code inside that. 😄👍
