Attention JavaScript gurus: Need a hand with setInterval()

由 心已入冬 提交于 2019-12-01 06:10:54
问题 I am trying to make a non interactive display for a real estate shop window. It's been a while since I've played with setInterval() . The first time my script steps through, it is fine. But when it tries to get the next property via getNextProperty() , it starts to go haywire. If you have Firebug, or an equivalent output of console.log() , you'll see it is calling things it shouldn't! Now there is a fair bit of JavaScript, so I'll feel better linking to it than posting it all. Store Display

setInterval weird behavior in nodejs

问题 I want to run a function once every second, and the function itself takes 3 seconds to execute. the results are that each interval is executed at a difference of <function execution time>*2+<setInterval delay> I wrote the following sample code: var seconds = 3; setInterval( function(){ console.info(new Date().toString()); var waitTill = new Date(new Date().getTime() + seconds * 1000); while(waitTill > new Date()){} },1000 ); and each iteration is as I stated in the formula: Wed Jul 13 2016 09

Minimum setInterval()/setTimeout() delay on background tabs [duplicate]

问题 This question already has answers here : Closed 8 years ago . Possible Duplicate: Chrome: timeouts/interval suspended in background tabs? Is there a minimum allowed delay for setInterval() and setTimeout() when being run on a tab you're not currently looking at? This code runs setInterval() with a specified delay of 100ms and writes out how long the delay actually was. It also reports when you enter/leave the tab. <html> <body> <script type="text/javascript"> window.onfocus = function () {

How do browsers determine what time setInterval should use?

由 守給你的承諾、 提交于 2019-12-01 05:07:10
It would seem that in general, browsers will in certain cases modify, even beyond a minimum clamp, the actual time interval that setInterval uses. For instance, I have the following code: function start() { window.setInterval(function() { update(); }, 1); } lastTime = new Date; numFrames = 0; lastFrames = 0; function update() { numFrames++; if (new Date - lastTime >= 1000) { lastFrames = numFrames; numFrames = 0; lastTime = new Date; } } Here, lastFrames will give us the number of frames over what is approximately the past second. When used in Chrome, Firefox, and Safari, this code doesn't run

Get function associated with setTimeout or setInterval

由 Deadly 提交于 2019-12-01 05:01:36
问题 Let's assume that I have the timeout ID returned from setTimeout or setInterval . Can I get, in some way, the original function or code, associated with it? Something like this: var timer_id = setTimeout(function() { console.log('Hello Stackoverflowers!'); }, 100000); var fn = timer_id.get_function(); // desired method fn(); // output: 'Hello Stackoverflowers!' 回答1: You can put a wrapper around setTimeout - I just threw this one together (after a few iterations of testing...) (function() {

Does this behavior of setInterval imply multithreading behavior in Javascript?

问题 In using javascript i noticed this thing. You can use var i=0; var startingTime=new Date().getTime(); setInterval("foo()",1); function foo() { i+=1; if ($("#foodiv").text()==i) { //we detected a doubled value (parallel execution) $("#repdiv").append("[repetition on "+i+"]"); } $("#foodiv").html(i); $("#timediv").html(Math.floor((new Date().getTime()-startingTime)/1000)); } but as i read and try myself the time is not 1ms , it's at least 10ms or something. In fact after 10 seconds, i have a

i'm using setInterval to check if a p(html paragraph) has a certain text value. if it has it i want to clear interval an continue code flow. i'm using this in a jQuery plugin so if the paragraph has tat text value i want to clear interval and then continue with a callback function. so i tried something like this: var checkTextValue = setInterval(function(){ var textVal = $('p').text(); if(textVal == 'expectedValue'){ clearInterval(checkTextValue); callback(); } },10); and the callback function it's a simple alert. My problem is that the alert is called endlessly. How can i write my code to do

jQuery - How to restart setInterval after killing it off with clearInterval?

由 被刻印的时光 ゝ 提交于 2019-11-30 18:06:21
I want to create a page with 2 buttons, 'STAY' and 'Leave'. There is an iFrame underneath the buttons. When the page loads for the first time, the iFrame starts refreshing automatically after 10 secs. When the user hits STAY button, it will stop refreshing. After that if he hits LEAVE button the iFrame will again start refreshing after 10 secs. I'm using this code: $(document).ready(function() { var refreshIntervalId = setInterval( "update()", 10000 ); $('#leave').click(function () { var refreshIntervalId = setInterval( "update()", 10000 );; }) $('#stay').click(function () { clearInterval

setinterval() and clearinterval() - when cleared, does not animate automatically

由 三世轮回 提交于 2019-11-30 16:03:20
问题 So I'm trying to build an animating background image which will cycle through an array of images. The idea is also that when you click any navigation element on the page, the cycle will pause. When you click on the home button, the cycle is to start up again (from the current image). This works in it's current state, however the cycle is not automatic upon re-firing it, instead you have to press the home button for each fade/slide/whatever. The script is as follows: $(document).ready(function

Node.js setInterval() stops executing after 25 days

由 ℡╲_俬逩灬. 提交于 2019-11-30 13:56:08
In my Node.js application, I use setInterval() to run a specific function every 1 hour. The function is executed properly for about 25 days, then the timer stops firing. 25 days seems awfully close to Node.js's TIMEOUT_MAX (2^31 milliseconds ≈ 25 days), but I don't really see why setInterval() should stop executing after that time. Update: I think this may have been caused by the following bug in Node.js: setInterval callback function unexpected halt #22149 It seems the bug ( #22149 ) has been fixed in Node.js 10.9.0 . It may be also worth noting that this bug seems to be influencing both
