How can I repeat a function doSomething() every 5 seconds.
I also need code that will make it stop doing it.
And code to on-the-fly adjust the frequency.
setTimeout() will only launch the command once. In this case, setInterval() is your friend.
var iFrequency = 5000; // expressed in miliseconds
var myInterval = 0;
// STARTS and Resets the loop if any
function startLoop() {
if(myInterval > 0) clearInterval(myInterval); // stop
myInterval = setInterval( doSomething(), iFrequency ); // run
}
function doSomething()
{
// (do something here)
}
from code...
<input type=button onclick=iFrequency+=1000; startLoop(); return false;
value=Add 1 second more to the interval />
