问题 How do I reset a setInterval timer back to 0? var myTimer = setInterval(function() { console.log('idle'); }, 4000); I tried clearInterval(myTimer) but that completely stops the interval. I want it to restart from 0. 回答1: If by "restart", you mean to start a new 4 second interval at this moment, then you must stop and restart the timer. function myFn() {console.log('idle');} var myTimer = setInterval(myFn, 4000); // Then, later at some future time, // to restart a new 4 second interval

Javascript, setTimeout loops?

问题 So I am working on a music program that requires multiple javascript elements to be in sync with another. I've been using setInterval which works really well initially however over time the elements gradually become out of sync which with a music program is bad. I've read online that setTimeout is more accurate, and you can have setTimeout loops somehow however I have not found a generic version that illustrates how this is possible. Could someone just show me a basic example of using

Javascript - Pausing setInterval()

问题 How do I pause and resume the setInterval() function using Javascript? For example, maybe I have a stopwatch to tell you the number of seconds that you have been looking at the webpage. There is a 'Pause' and 'Resume' button. The reason why clearInterval() would not work here is because if the user clicks on the 'Pause' button at the 40th second and 800th millisecond, when he clicks on the 'Resume' button, the number of seconds elapsed must increase by 1 after 200 milliseconds. If I use the

Trouble with setInterval and undefined arguments

问题 I'm trying to create a basic strobe light in the browser using the canvas element. I'm expecting setInterval to keep calling the changeBG function to change to a random background color. This function works fine on its own, but not when called by setInterval. I tried pulling up this page in firebug and it told me that colors was undefined. Here's the problematic code. <html> <head> <title>Strobe!</title> <link rel="stylesheet" type="text/css" href="reset.css" /> <script type="text/javascript"

How do I make Ajax calls at intervals without overlap?

由 廉价感情. 提交于 2019-12-14 00:20:38
问题 I'm looking to setup a web page that samples data via AJAX calls from an embedded web-server. How would I set up the code so that one request doesn't overlap another? I should mention I have very little JavaScript experience and also a compelling reason not to use external libraries of any size bigger than maybe 10 or so kilobytes. 回答1: You may want to consider the option of relaunching your AJAX request ONLY after a successful response from the previous AJAX call. function autoUpdate() { var

问题 I'm trying to get offline.js working together with toastr alerts. My limited JS knowledge is holding me back but hoping some can shed some light on this. What I want to happen When the connection goes from down to up, I want to display a "re-connected successfully" message in a toast alert. The Problem I don't understand how to check for that status in offline.js. The docs mention that it's possible using this: Offline.on(event, handler, context) : Bind an event. Events: up: The connection

The problem is that when the part of the page including the countdown is loaded again using jquery

Trigger Alert When Slider Moves Left A Certain Amount

由 社会主义新天地 提交于 2019-12-13 10:54:11
问题 So, I am going to actually kill two birds with one stone. First off, I am trying to trigger an alert once the slider moves left to a specific degree. For example, once it goes to, let’s say, the 3rd slide I would like for it to trigger an alert. Also, I need help with the cycling of the slider. I want the slider to cycle like a rotation (360), but instead at the end of the cycle it slides all the way back to the start. View the Codepen to have a better understanding of what I mean. Thank you
