Setinterval & Settimeout?

I want to stop my javascript after x seconds, I saw that the function is setTimeout, I tried to add that to my code but no succes, is this the better way to do this? Thanks for you

Solution 1:

Initialize your interval in a variable and clear it after X (here 2) seconds:

var interval = setInterval(blink, 300);

setTimeout(function() {
    clearInterval(interval);
}, 2000);

Solution 2:

use like this:

var myvar;

functionmyStartFunction()
{
    myvar=setInterval(function(){blink()},300);
}
functionmyStopFunction()
{
clearInterval(myvar);
}
