I stumbled upon a problem though. When I tested it the number was 2781, but it could be anything, and you only need it if you want to cancel the action later. In this tutorial we'll look at JavaScript's setTimeout(), clearTimeout(), setInterval() and clearInterval() methods, and show how to use them to set timers and create delayed actions. Is it possible to stop calling it on some event? The Javascript setTimeout() function allows code to be executed a set time after some trigger, such as when the page has loaded or a button is pressed. With this, nothing will be printed to the console, because a second timer cancels the first one before the first one has a chance to run. Nested setTimeout calls are a more flexible alternative to setInterval, allowing us to set the time between executions more precisely. Execution with 0ms delay. This can be used later to cancel the setTimeout before it triggers. Zero delay scheduling with setTimeout(func, 0) (the same as setTimeout(func)) is used to schedule the call “as soon as possible, …

A popular technique to improve the performance of JavaScript code is to set timers with setTimeout calls that have a delay of 0ms. This post looks at how to trigger events after a set time with Javascript and alsp how to clear the timeout. When I tested it the number was 2781, but it could be anything, and you only need it if you want to cancel the action later. On a specific page in my application I think of doing a server-call to update information on a set interval. I am using setInterval(fname, 10000); to call a function every 10 seconds in JavaScript. Darum wird setTimeout hier im Beispiel innerhalb der Funktion countdown wiederholt aufgerufen, bis die Bedingung (time > 0) nicht mehr stimmt. Javascript setTimeout() führt die Anweisungen exakt einmal aus (und der Timer ist nicht besonders exakt) und dann nie wieder.
