Restarting a setInterval() in Javascript/jQuery (without clearInterval)

由 喜你入骨 提交于 2019-12-07 02:51:47
问题 I'm working on ui tabs built using jQuery. Everything works except for one issue - I did a setInterval that runs a function that does a trigger("click") so that it goes to the next tab after 5000 miliseconds. It runs through each tab fine, the issue is that if the user manually clicks on a tab, the timer for the setInterval does not restart back at 0. For example if a user were to start on tab1 at 0 miliseconds and clicks on tab2 at 2000 miliseconds, the setInterval doesn't go back to 0, it

Add a pause/interval to every iteration in a FOR LOOP

由 回眸只為那壹抹淺笑 提交于 2019-12-07 02:35:28
I want to write a for loop which prints number 1 to 10 with intervals after every iteration " like this " How can I achieve it? I tried sleep() setInterval() setTimeout(") and what not but can't seem to find any working solution. And if possible I would like to do this using pure Javascript only. function abc(){ for(i=1;i<=10;i++){ document.write(i+"<br>"); sleep(1000); } } To answer the question, to get something like a sleep function you could just write somehting like this as a helper function function sleep(dur) { var d = new Date().getTime() + dur; while(new Date().getTime() <= d ) { //Do

Making a live clock in javascript

由 北战南征 提交于 2019-12-07 01:35:03
问题 The clock kinda works. But instead of replacing the current time of day it prints a new time of day every second. I understand why it do it but I don't know how to fix it. I would appreciate if you could give me some tips without saying the answer straight out. Thank you. Here is my code: function time(){ var d = new Date(); var s = d.getSeconds(); var m = d.getMinutes(); var h = d.getHours(); document.write(h + ":" + m + ":" + s); } setInterval(time,1000); 回答1: Add a span element and update

小记VUE下setTimeOut和setInterval遇到的问题

由 假装没事ソ 提交于 2019-12-06 20:37:36
相信大家对着两个函数都陌生，就是一个定时器，setTimeOut只执行一次，而setInterval会重复执行 需要注意的是：在setInterval不用的时候一定要用clearSetInterval关闭定时器。 说一下最近开发中遇到的问题，我是用 vue 开发的，顺便记录这个错误。 我需要轮询接口，所以使用setInterval。 // 我是想没2秒执行一次myFunc这个函数。 setInterval(this. myFunc() , 2000 ) //某个函数 myFunc () { console .log (123) } 但实际的运行结果是，只执行了一遍，并没有循环执行。 原因是setInterval接受两个参数，第一个为要执行的 函数 ，第二个为时间（毫秒）。 这里我犯的错误是，我写的是一个函数的 执行 this.myFunc() 因为加了（）是一个执行，而不是个函数。 于是我又改成这样写了，在写个匿名函数，函数体是我要执行的。 setInterval( function () { this .myFunc() }, 2000 ) //某个函数 myFunc () { console.log( 123 ) } 理论上这样是没问题的，会每2秒执行一次this.myFunc()，但却报错了。 原因是 老生常谈的javaScript 的this 的问题。

Javascript loop-problem with setTimeout/setInterval

由 被刻印的时光 ゝ 提交于 2019-12-06 20:24:31
var flag = 0/1 (default=1) I want this flag to checked every 30sec over and over until the flag becomes 0 (by an external event that I cant control). When the flag is 0 the 30sec-check should end until the flag is 1 again As long as the flag is 0 some text should blink on the screen, if the flag goes back to 1 the blinking should stop and the 30sec check should continue. I tried to do this with setTimeout/setInterval but Im having problem combining them with loops. Here is some code doing the blinking from another site: <html> <head> <script type="text/javascript"> function init() { window

What is the optimal way to use setInterval in jquery ajax calls?

由 夙愿已清 提交于 2019-12-06 15:47:38
I am using JQWidgets to create a pie chart. And while that is all fine and dandy and working like a charm. What I'd like to do however is update the data every x number of seconds. Using jQuery, here is the code that I have so far: function loadChart(id,name){ //chart loads here var speed = 5000, t = setInterval(reloadData,speed); function reloadData() { source.url = 'data.php?id='+id; var dataAdapter = new $.jqx.dataAdapter(source); $('#pie').jqxChart({ source: dataAdapter }); console.log('reloading pie...'+globalPieId); speed = 5000; clearInterval(t); t = setInterval(reloadData, speed); } }

Can JavaScript's setInterval block thread execution?

问题 Can setInterval result in other scripts in the page blocking? I'm working on a project to convert a Gmail related bookmarklet into a Google Chrome extension. The bookmarklet uses the gmail greasemonkey API to interact with the gmail page. The JavaScript object for the API is one of the last parts of the Gmail page to load and is loaded into the page via XMLHttpRequest. Since I need access to this object, and global JavaScript variables are hidden from extension content scripts, I inject a

Javascript/Jquery Refresh timer

由 和自甴很熟 提交于 2019-12-06 12:13:24
问题 I have a simple system that refreshes a div every few seconds: $(document).ready(function() { $("#nownext").load("response.php"); var refreshId = setInterval(function() { $("#nownext").load('response.php?randval='+ Math.random()); }, 20000); }); Now, because of what the content is, it is more likely to update on the hour, or at half past. (Though not always). What I'd like to do it make the system refresh MORE often between a few minutes before and after the hour (and half past), just to make
