setTimeout should only run once. You’re looking for setInterval. var loop_handle = setInterval(slide, 3000); Also, the second argument should be a number, not a string. When the function call doesn’t require any arguments, it’s better to reference to the function instead of using a string. A string would be converted to a function. This function … Read more
It doesn’t have a minimum delay and this is actually a compatibility issue between browsers and node. Timers are completely unspecified in JavaScript (it’s a DOM specification which has no use in Node and isn’t even followed by browsers anyway) and node implements them simply due to how fundamental they’ve been in JavaScript’s history and … Read more
It shouldn’t, given this: handle = window . setTimeout( handler [, timeout [, arguments ] ] ) Let handle be a user-agent-defined integer that is greater than zero that will identify the timeout to be set by this call.
You can use the Timer class import ‘dart:async’; var timer = Timer(Duration(seconds: 1), () => print(‘done’)); timer.cancel();
JavaScript runs in an environment that is defined by a global object. Methods of the global object can be called without explicitly refering to the object (i.e. without the obj.function() notation). When you run JavaScript inside the browser, the global object is provided by the Document Object Model (DOM). The global object of the DOM … Read more
You’re calling the function immediately and scheduling its return value. Use: setTimeout(testFunction, 2000); ^ Notice: no parens.
The return value of setInterval is just a unique id you use to pass back to clearInterval. It’s not a structured object with any additional information, nor does it get set to null when you call clearTimeout.
Returns a value which can be used to cancel the timer. So, it would seem unlikely that they return the same value (unless they are reusing values and one of the timers has already been cancelled) Mozilla states it’s DOM level 0, but not part of the specification. (look at the bottom of the page) … Read more
It’s not supposed to be particularly accurate. There are a number of factors limiting how soon the browser can execute the code; quoting from MDN: In addition to “clamping”, the timeout can also fire later when the page (or the OS/browser itself) is busy with other tasks. In other words, the way that setTimeout is … Read more
What Jason said is totally correct in his answer but I thought I would give it a shot, to better clarify. This is actually a classic closure problem. Typically it would look something like: for(var i = 0; i < 10; i++){ setTimeout(function(){ console.log(i); },i * 1000) } The novice would expect the console to … Read more
