I recently asked about this and it is behaviour by design. When a tab is inactive, only at a maximum of once per second the function is called. Here is the code change. Perhaps this will help: How can I make setInterval also work when a tab is inactive in Chrome? TL;DR: use Web Workers.
Your sleep function does not work because setTimeout does not (yet?) return a promise that could be awaited. You will need to promisify it manually: function timeout(ms) { return new Promise(resolve => setTimeout(resolve, ms)); } async function sleep(fn, …args) { await timeout(3000); return fn(…args); } Btw, to slow down your loop you probably don’t want … Read more
EDIT: In summary, back in 2010 when this question was asked the most common way to solve this problem was to save a reference to the context where the setTimeout function call is made, because setTimeout executes the function with this pointing to the global object: var that = this; if (this.options.destroyOnHide) { setTimeout(function(){ that.tip.destroy() … Read more
The first form that you list works, since it will evaluate a string at the end of delay. Using eval() is generally not a good idea, so you should avoid this. The second method doesn’t work, since you immediately execute a function object with the function call operator (). What ends up happening is that … Read more
setTimeout(function() { postinsql(topicId); }, 4000) You need to feed an anonymous function as a parameter instead of a string, the latter method shouldn’t even work per the ECMAScript specification but browsers are just lenient. This is the proper solution, don’t ever rely on passing a string as a ‘function’ when using setTimeout() or setInterval(), it’s … Read more
You’re calling the function immediately and scheduling its return value. Use: setTimeout(testFunction, 2000); ^ Notice: no parens.
I noticed a couple of issues with your code. You are calling setTimeout in a loop. So if you have, say, numOfbox.length === 15, setTimeout will be called 15 times around 10,000 ms from when you set it. Could this be the reason you’re seeing the more calls to startGame than you thought? I see … Read more
Although your code works as expected, it could be that under some conditions you wouldn’t print all numbers. It might be better to check the counter value and then clear the interval at that time (timing in javascript is not really that precise as you might hope it to be) You could try to do … Read more
You cannot really use the setTimeout() function as you suggest… I guess this is roughly what you are looking for: echo <<< EOT <script type=”text/javascript”> setTimeout(function() { window.open(‘https://mywebsite/$link’, ‘_blank’); }, 1000); </script> EOT; Note: I just use the nowdoc notation since it is easier to read. Certainly it is possible to use a normal literal … Read more
It’s because variable in for loop is the same in each iteration (same reference) and when setTimeout is running the for loop has ended so the i variable will be last value of the loop, to fix this you can create a closure with i variable: function play(step){ var buttons = document.querySelectorAll(‘.age’); buttons[0].click(); for (var … Read more
