Generating Time Intervals

[Nohana]

Is there any simpler way to generate a wait time between events other than using setTimeout() and clearTimeout()?Take for instance the following example:

--JAVASCRIPT--var count=100;function setCountdown() {if(count > 0 ) count--;setTimeout("setCountdown()", 1000);}--HTML--<input type="button" onclick="setCountdown()" />

Isn't calling the function over and over hard on the browser? What's more, if the user keeps clicking on the button, the countdown would go faster than it should and I'd need to add another line of code to prevent this. Isn't there a way to get the same result using a looping such as while or for statement?

calling it every second is fine for the browser just don't go calling it every 1 millesecond :)That is the common way of doing a countdown. Loops will not wait they just execute as fast as they can.

setTimeout returns a value, you can use that value to check if they click the button again and clear the previous timeout if it's already been set before setting the new one (or don't set the new one at all).
