Answer 1

No the timer works. I think you would like to stop definitively moving the box ?

Answer 2

The difference is ( in your code ) the timer will show 61 instead of 60.

Answer 3

@Sina

var sec = 0;
var num = 1;
function repeat(){
var speeds=[Math.floor((Math.random()*50) + 80)];
var x = document.getElementById("mar");
x.scrollAmount=speeds;
++sec;
if (sec>=60){
clearInterval(y)
document.getElementById("mar").scrollAmount = 0;
}

Answer 4

I added a var named sec wich is incremented every seconds

Answer 5

@Sina

function timer(){
document.getElementById("p2").innerHTML = ++num
if(num >=60){
clearInterval(x)
}
}
var x = setInterval(timer,1000)

Answer 6

You saved y for the repeat function not for the timer. Your post is about the timer so I had not look at the repeat function. The clearInterval works but it just let a constant speed to the square. If you want to stop it you add to clear the interval and then to set the speed as 0

Answer 7

Yes but save it into a y variable

Answer 8

You have two variables named y

Answer 9

@Sina it works for me

Answer 10

the clearInterval doesn't work

Answer 11

@Sina sorry I didn't understand that's your problem. You clear an interval named y but the interval y does not exist. You just have to declare it using :
var y = setInterval(timer, 1000);
instead of :
setInterval(timer, 1000);

Answer 12

there is that setInterval()

Answer 13

I saved it see
