clearInterval before setTimeout wont work

由 China☆狼群 提交于 2019-12-08 13:35:24
问题 I have a problem with clearing an interval. I have 3 functions start1 , start2 , start3 . Here you can see only the first. The function count1 and variable myVar1 have the same princip they are the same numbered. Now the problem is that clearInterval only works after the first function (See console log). After the second start2() anything happens what I cant explain by myself. I made a demo. start1(); function start1() { var valuem = 0, dir = 1; $('#number').text(valuem); function count1() {

setinterval not able to run document.writeln

问题 Greetings, The code below works for alert but doesn't for document.writeln. Is it because of the onload event? If so shouldn't the browser be able to add more elements after it's finished loading? - Trying to understand how it works (I am studying jquery in the meantime). <body onload="timeMsg()"> <script type="text/javascript"> function timeMsg() { var t=self.setInterval("randInt()",3000); } function randInt() { document.writeln("<br />" +Math.floor(Math.random() * 7)); //doesn't work alert

jQuery auto refresh page on clock time

由 送分小仙女□ 提交于 2019-12-08 10:40:09
问题 How do I refresh the page automatically every 15 minutes based on clock time? For example: refresh on 9:00, 9:15, 9:30, 9:45, 10:00, 10:15, so on.. I have seen one similar like I wanted : https://stackoverflow.com/a/1217945/551559 but I don't think it does the job. setInterval(function(){ // check clock time on every minute?? if ( clock_time === '9:15' ) { } },1000); Can someone give me a solution or any link to look at? 回答1: setInterval(function(){ var minutes = (new Date()).getMinutes() if

Temporary changing the time of setInterval

由 我怕爱的太早我们不能终老 提交于 2019-12-08 09:33:42
问题 The timing value in setInterval determines the next time at which the function is going to be invoked again. For example: t = 8000; myFunction(){ if (someCondition){ //halt setInterval //t = 5000; // setInterval(myFunction,t); } // do some logic } setInterval(myFunction, t); The problem is changing of t will not affect the time that I want the current call to be remained before the next call. In other words, is there any way to halt setInterval and then I can reset it again with new time? 回答1

Disable timer within setInterval function with dynamic parameters

由 拜拜、爱过 提交于 2019-12-08 08:13:00
问题 I wanted to pass dynamic parameters into a setInterval function (see question here) and specifically @tvanfosson's comment. But now, I also want to disable that timer if a certain condition is met. I tried to define the timer variable as a global variable but I still get the timer as a undefined on this line: console.log('else. timer=' + timer); : else. timer=undefined <script language="javascript" type="text/javascript"> var timer; var params={}; params.color='light'; $(document).ready

I'm trying to display the current time in a view based on a Javascript Date object in my controller.

问题 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).
