JavaScript - Help With Setting A Delay For A Loop (settimeout Isn't Helping)
I have a while-loop and I need it to make a little delay before each time it starts a new cycle.
Code: var rollOn = true;
while(rollOn)
{
//A bunch of statements.
//The loop breaks in case of certain conditions so that "rollOn = false;".
var t = setTimeout("continue", 1000);
} //End while
The problem is that setTimeout doesn't delay for a second before the "continue" statement. For example, when I write: Code: var t = setTimeout("alert("Delay")", 1000);
then it displays the alert box after every cycle of the loop, but still no delay. There are no error messages or anything, I'm not really sure what's the problem, thus I don't know what to do about it. Any ideas? Similar TutorialsI'm trying to delay this line by 1 second, but can't seem to figure out the syntax. Code: window.location.href="index.php?vid_id="+<?php echo $vid_id +1 ?>; this is the entire function Code: $('#cancel').click(function() {
$.ajax({
type: "POST",
url: "scripts/greenlight.php?vid_id="+<?php echo $vid_id ?>,
data: "vote=2",
success: function(){
}});
document.getElementById("greenlight").src="img/greenlight_btns/greenlight_btn.png";
document.getElementById("cancel").src="img/greenlight_btns/cancel_btnOver.png";
//window.location.href="index.php?vid_id="+<?php echo $vid_id +1 ?>
window.setTimeout(function()
{
window.location.href="index.php?vid_id="+<?php echo $vid_id +1 ?>;
}, 500);
}); // end click
Hi, this must be simple but I don't get it work. I need to do the following delay within a loop: var position; for ( var i=1; i < 100; i++) { position++; setTimeout("", 1000); // delay for loop; } // end for loop; It does not work, because setTimeout needs always the function parameter within the "". There must be a way around this !? Thanks you for your help ! Claus Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Basically, what I'm trying to do is get a random number every second for 2 seconds automatically so that in the status window it says: "You earned $2" "You earned $3" ....etc. But my random number keeps showing up as 0. I know I'm probably overlooking something as far as closures...can someone please enlighten me? Check the javascript code tried this also..same result for everything I try: D: Code: function Machine()
{
this.rand = 0;
this.r = function()
{
this.rand = Math.ceil(Math.random() * 4);
}
this.getCash = function()
{
var i = 0;
while (i < 3)
{
t = setTimeout("this.r()", 1000);
alert(this.rand);
i++;
}
clearTimeout(t);
}
}
var soda = new Machine();
soda.getCash();
i need to make a function that will send a string to my perl script then recieve the answer and set a div innerhtml to the answer.. i plan on sending the string from the div onload as i will have about 30 divs that need changing. Code:
<body>
<div name="example1" onload="javascript:retrieve('getstring1')">my retieved string1</div>
<div name="example2" onload="javascript:retrieve('getstring2')">my retieved string2</div>
</body>
<head>
<SCRIPT language="JavaScript">
function retieve('var') {
}
</SCRIPT>
</head>
im not quite sure where to go with this but i can easily make the perl script do if statements on the string and return the correct string to put into the div. the reason for this is that the string will be changed every couple weeks. there is probably a better way to do this but this would be more appropriate for me This is what I have: Code: <script type="text/javascript">
$(document).ready(function(){
$('#add').click(function() {
alert ('test')
});
$("form#exercise").submit(function() {
// we want to store the values from the form input box, then send via ajax below
var activity = $('#activity').attr('value');
$.ajax({
type: "POST",
url: "newActiveProc.php",
data: "activity="+ activity +"&func=search",
success: function(msg){
$("span#results").html(msg);
}
});
return false;
});
});
</script>
Instead of alerting the user, I want to send their choice to the a table on the same page. Does anyone have any idea of how I might do this. I've posted three threads in the ajax forum with no response. Hello how can I add a time delay to a function, so that the called function will execute only after a certain length of time. For example if I want a div to go 'hidden', 3 seconds after hovering off of a second div? Here is the script code I'm wanting to add the delay to: Code: <script>
function show(id) {
document.getElementById(id).style.visibility = "visible";
}
function hide(id) {
document.getElementById(id).style.visibility = "hidden";
}
</script>
and Code: <div id="div1" onmouseover="show('div2'); fade_in('div2', 2);" onmouseout="fade_out('div2', 2); hide('div2');">
The reason I need this delay is so the fadeout function (which also executes after hovering off the second div completely finishes the fadeout before the hidden function executes. Hi all. The below script is from suckerfish. Can anyone help me include a 'one sec delay' to keep the menu open onmouseout. First menu often closes too fast before I get a chance to move onto submenu. I've tried everything with setTimeout BUT I just can't get it right. Nothing I do works. Can somebody PLEASE show me so I can kick myself. LT Code: <script type="text/javascript"><!--//--><![CDATA[//><!--
sfHover = function() {
var sfEls = document.getElementById("nav").getElementsByTagName("LI");
for (var i=0; i<sfEls.length; i++) {

}
sfEls[i].onmouseout=function(){
this.className=this.className.replace(new RegExp(" sfhover\\b"), "");

Hi I am creating an animation based on Sam Dunn's tutorial 'Animate Curtains Opening with jQuery' ( http://buildinternet.com/2009/07/ani...g-with-jquery/ ).

Thanks. Jet. Hello All, This is my first post here, so hopefully I don't make to big an *** out of myself. Anyway, I am working on a small 2D game in javascript, and have character movement bound to the onkeydown event. The problem is, that there is a momentary delay between pressing the key, and then it realizing you are still holding it down. So it's Move->stop->Move smoothly You can see what I'm talking about here http://www.digitalswordsmen.com/at/townmap.cfm I know that the delay is happening at the operating system level (you see the same kind of delay if you open up notepad and hold down a letter key, first letter appears instantly, then a short delay before continuing). I was wondering if anyone has a possible solution though, or someway I could smooth out that delay. Also, the walking animations only seem to work in firefox. I guess IE doesn't play animated gifs while the onkeydown even is being fired. Not sure if there is a fix for that, other than animating the individual frames with JS, but that would be pretty laggy I think. Anyway, any input is appreciated. You can see all the code by of course just viewing source, its still fairly simple at this point. Thanks in advance. Is there another JS function that I can use to force a time delay without having the code continue to run? I'm using the setTimeout() function but the call to this function doesn't stop the code flow. I need to stop the code flow while waiting. I guess I need a Sleep() type of JS function. What I'm trying to do is display some blank text on the screen using a for loop (I'm using <BR> to give the appearance of "opening up" a vertical window section in the browser) and I need this 'text' to complete before allowing the following code in the function to execute. The following code will display a Table with rows of data. I'm trying to use a timing function to give a visual impression of a window opening up just before the data displays. Thanks... Okay, for some reason the setTimeout isn't working for me, and I have no idea why. I've tried everything and Googled even more. If anyone has any ideas, I'll be grateful Code: function display(min,sec) {
if (sec <= 0) {
sec=60;
min-=1;
}
if (min <= -1) {
sec=0;
min=0;
tEnd();
} else {
sec = sec-1;
}
if (sec<=9) { sec = "0" +sec; }
document.form.time.value=min+":"+sec;
SM = window.setTimeout("display("+min+","+sec+")",1000);
}
function tEnd() {
window.clearTimeout(SM);
alert('Your time is up!');
}
Thanks in advance. Hi trying to load a random swf files using setTimeout please help Code: </head><script type="text/javascript">
var numberOfSongs = 3
var sound = new Array(numberOfSongs+1)
sound[1]= "number/1.mp3"
sound[2]= "number/2.mp3"
sound[3]= "number/3.mp3"
function randomNumber(){
var randomLooper = -1
while (randomLooper < 0 || randomLooper > numberOfSongs || isNaN(randomLooper)){ randomLooper = parseInt(Math.random()*(numberOfSongs+1))
}
return randomLooper
}
var randomsub = randomNumber()
var soundFile = sound[randomsub]
document.write ('<EMBED src= "' + soundFile + '" hidden=true autostart=true loop=false>')

Hello guys I need to get something fun! with setTimeout function! I am n00b! so be patent please. I need when <body onload="Myfunc();"> fires, that function should show "Please wait...!" or "Loading...". for , say 5 seconds!. then it disappear. I used setTimeout with that but it didn't do what I wanted! here is my code: PHP Code: function Myfunc(){ document.getElementById("ss2").innerHTML = "Loading..."; setTimeout("Myfunc();", 5000); } // where id="ss2" is the place to display the string "loading..." ! and a one more question ! can I do something like a while loop! where it holds *i* value as seconds! and for every second it passes it should print out a string I make it up ! let say loop for 3 seconds ! So, when seconds = 0 then display "string of second 0" and stick it in there, then go to the next second when it is exactly = 1 then display "new line with string of second 1" and stick it in there, then do to the last second when it is exactly = 2 then display " new line with string of second 2" and stick it in there, exit the loop! is there anyway to do that? please note that I am a n00bie ! help is much appreciated ! Hello - I've got this lovely little animation that slides some div fields to the right a short distance. Everything works except the setTimeout (located in the SlideIn function). It simply 'jumps' without taking any time at all. I've tried a bunch of stuff: changed the amount of time from 100 to 10000 changed it from var t = setTimeout("SlideIn()", 1000) SlideIn with/without the brackets, with/without the quotation marks. SlideIn() SlideIn(i) SlideIn(label_id_fixed) SlideIn(label_id_no) Just about at the end of my rope, and so many different combinations I'm forgetting which ones I've tried and which I haven't. I know it is looping through because it gets to the end position and allows the other JavaScript functions to work ok. So it is not getting 'stuck' or anything like that.

I have an AJAX search bar what searches after each keyup, but id like to make it so it runs the search if theres a certain delay after the keyup so if you search "hello" it doesnt run 5 times, only once (because there wont be a half a second gap between each letter.

Also I would like to know if there is a way I can redirect the page if they do not respond within the countdown time that would go back to the mobile site home page. Also If they leave the coupon page and then go back to the coupon page could I make it so the countdown would still be running as if they never left. I am including the code for the coupon.
