How do I correctly use setInterval and clearInterval to switch between two different functions?

For practice I am trying to display a number that increments from 0 - 9, then decrements from 9 - 0, and infinitely repeats. The code that I have so far seems to be close, but upon the second iteration the setInterval calls of my 2 respective functions countUp and countDown seem to be conflicting with each other, as the numbers displayed are not counting in the intended order... and then the browser crashes. Here is my code: <!DOCTYPE html> <html> <head> <title>Algorithm Test</title> </head> <body onload = "onloadFunctions();"> <script type = "text/javascript"> function onloadFunctions() {

Say someone (evil) has set us a timer with setInterval , but we don't know its ID (we don't have the reference to the object, that setInterval is returning, nor its value) (function(){ setInterval(function(){console.log('pwned')}, 10000) })(); Is there a way, how to clear it?

Are clearTimeout and clearInterval the same?

由 ぐ巨炮叔叔 提交于 2019-11-26 07:36:30
问题 When working on some Javascript for a web application, I noticed that I had used setTimeout , but I had tried to clear it with clearInterval and it stopped the timeout from occurring in Google Chrome and Internet Explorer 9. Are clearTimeout and clearInterval interchangeable? Here\'s a JSfiddle with an example of what I\'m talking about. 回答1: No, they are not interchangeable. Sure, some browsers may very well share the same code to clear intervals and timeouts the same way, but does not mean

Code for a simple JavaScript countdown timer?

由 放肆的年华 提交于 2019-11-26 00:24:48
问题 I want to use a simple countdown timer starting at 30 seconds from when the function is run and ending at 0. No milliseconds. How can it be coded? 回答1: var count=30; var counter=setInterval(timer, 1000); //1000 will run it every 1 second function timer() { count=count-1; if (count <= 0) { clearInterval(counter); //counter ended, do something here return; } //Do code for showing the number of seconds here } To make the code for the timer appear in a paragraph (or anywhere else on the page),
