Recursive Function With For Loop, For Loop Is Breaking When Calling Itself
Jan 22, 2011I have been looking at this code for two evenings now, and rewrote it 4 times already. It started out as jQuery code and now it's just concatenating strings together.
What I'm trying to do: Build a menu/outline using unordered lists from a multidimensional array.
What is happening: Inside the buildMenuHTML function, if I call buildMenuHTML, the for loop only happens once (i.e. only for 'i' having a value of '0'.) If I comment out the call to itself, it goes through the for loop all 3 times, but obviously the submenus are not created.
Here is the test object:
test = [
{
"name" : "Menu 1",
"url" : "menu1.html",
"submenu" : [
[Code].....
'Menu 2' and 'Menu 3' don't show up! I'm sure it's something small that I'm overlooking.
Send A Loop Variable (i) To A Function Inside The Loop
Aug 4, 2011I'm looking to send a loop variable (i) to a function inside the loop, but I can't seem to get it to use the value I want, it keeps making it a reference of i and therefore the function is always called using the last value of i rather than the one it was set with.
So if i have 5 Tabs then Tab 1, when clicked, should call DefaultTabClick(0) and so on rather than always using 4 for any of the tabs.
'this' And SetInterval
Nov 23, 2005If I have some code that's a bit like this
Con = function() {
this.op = 1;
this.count = 0;
}
Con.prototype.loop = function() {
this.doNext = setInterval(this.next, 100);
}
Con.prototype.next = function() {
this.count++;
if (this.count > 10) clearInterval(this.doNext);
}
obj = new Con();
when I call obj.loop(); 'this' in obj.next refers to setInterval
and not obj . I realise I can add var ref = this; and send it with
setInterval but is there something I can do to get 'this' to refer to
obj when in obj.next?
SetInterval() Help
Feb 8, 2006I'm attempting to create a small function that when called upon will change the CSS background property 10 times at 80 millisecond intervals. I'm pretty sure setInterval() is the way to go about this, but I've been toying with my script for an hour and can't get anything to work.
At each 80 millisecond interval, the CSS background property should change like so:
background: url("image.png") 0 0 no-repeat;
background: url("image.png") 0 20px no-repeat;
background: url("image.png") 0 40px no-repeat;
background: url("image.png") 0 60px no-repeat;
and so on.
I would normally just use the background-position property, but it seems the hyphen throws javascript for a slip. It's really not necessary for this function, but if there's a way to use hyphens, it would be good to know for future reference.
Mozilla And SetInterval
Jul 20, 2005Is some future Mozilla going to support setInterval ( <function:function>,
<interval:number> ) ?
Right now it seems to be simply setInterval ( <function-text:string>,
<interval:number> )
SetInterval Animation
Mar 16, 2007I want to use the setInterval function to animate a menu sliding down when the user clicks on a link. here's a snippet:
box.timer = window.setInterval(
function() {
box.heightCount++;
if(box.heightCount >= maxHeight) {
window.clearInterval(box.timer);
}
box.style.height = box.heightCount + 'px'
}, 1);
So this works ok in the sense that the animation is performed smoothly. But to my understanding it should expand the height of the box 1pixel every 1ms, so it should expand very quickly from the base height to the maxHeight limit, but I click on the link and it animates soooooo slooooowly -- smoothly, i mean, but it takes well over a minute to expand to the full height. I just need to speed the damn thing up! Also, if i change "box.heightCount++;" to "box.heightCount+=1;" it gets all messed up. What am I missing here?
Using SetInterval In Loops
Dec 15, 2007i'm scratching my head over achieving similar results with setInterval() function, and how I can keep it from looping infinitely.
I want to do something like this:
var i = 0;
var endTime = now + ((1000*60)*2); // 2 minutes after now
while (now <=endTime) {
i = i + 1;
now = new Date().getTime();
}
document.write("total iterations: " + i);
however you can't do this because of lag issues, so i'll settle for using setinterval on its smallest interval of a millisecond, here is my attempt to translate the above to a setinterval solution:
var endTime = now + ((1000*60)*2); // 2 minutes after now
var intervalID = setInterval(loopFunc(endTime),1);
function loopFunc(endTime,intervalID) {
if (new Date().getTime() <= endTime) {
i = i + 1;
} else {
clearInterval(intervalID);
}}
as you can see I have prolbems figuring out how to stop the interval from continuing to iterate, and passing the interval id, I'm clueless Also I'm clueless on echoing the total iterations via this method.
SetInterval / SetTimeout
Sep 3, 2005I'm trying to build the framework for an AJAX back/forward button fixer. Basically it uses the hash fix for them (using text after the # to add history objects). To this effect, the function to check for updates has to be run every second or so. No problem, I'll just use setInterval for that.
For whatever reason, though, setInterval gives me an error. Specifically that oldLocation (global variable) is undefined (in the checkURL function). So I try setTimeout. Same thing. When I just call the function explicitly once (adding checkURL(); to the end of the script) everything works wonderfuly; it's just setting it up on a timer that messes up. Frankly, I've no idea why it's doing this. (The bug just seems so odd) Maybe a more advanced JS coder can shed some light on it.. Code:

SetInterval Inside A Class
Jul 23, 2005how can i set an interval inside a class
exmpl.
var Class = (function() {
var interval = undefined;
function initInterval(instance) {
interval = setInterval("doSomething", 1000, instance);
}
function doSomething(instance) {
alert(instance.message);
}
function Constructor() {
this.message = "hello world";
}
Constructor.prototype.init = function() {
initInterval(this);
}
return Constructor;
})();
is not working correct. doSomething is not known. i think, setInterval
is not inside the class, so doSomething is private and unknown for the
interval.
JQuery :: SetInterval() Does Not Work
Jun 18, 2009I've developed a plugin for a simple slide show. and here is the code [URL] The problem is when I mouse over the pic, the console error logs: "slideSwitch is not defined" The same error would still happen if I define function slideSwitch(){} and call
setInterval("slideSwitch()", 1000);
SetInterval Not Working In Firefox
Apr 1, 2009Inside of $(document).ready(function () I have:
var refre****= setInterval(function(){
$('#mydiv').load("mypage.htm");
}, 9000);
This is working great in IE, it loads mypage.htm into mydiv every 9 seconds. If I change the contents of mypage.htm I can see it in mydiv after 9 seconds with IE, but not with Firefox.
With Firefox I can see the reloading symbol on top of the tab every 9 seconds, but I don't see the page changed.
Slideshow In DIV Through SetInterval Function
Feb 7, 2011I am new in web development. I think this problem is related to javascript, I have write script which will change images after 2sec, through setInterval function. Script is as follows.
<script>
var images = new Array ("img/1.jpg", "img/2.jpg", "img/3.jpg");
var currentIndex = 0;
function Start(){
setInterval("ChangeImage()", 2000);
}function ChangeImage(){
currentIndex++;
if(currentIndex == images.length){
currentIndex = 0;
}
document.images[0].src = images[currentIndex];
}
</script>
But when I place in img tag which is in third row div and reload page, these series of images show in first row div. It does not show where I have specified area for it in css.
First row div:
<div id="menu">
<img src="header/menu.png" name="menuImg"/>
</div>
My series of images show in this div when I load page.
3rd row div:
<div id="slideshow-img">
<img src="img/3.jpg" name="myimg" onclick="Start()"/>
</div>
I have checked there is no size issue in my images.
SetInterval Firefox Irregularity?
Nov 20, 2005I just encountered a rather strange issue with setInterval() in Firefox. Take for example this code:
function test(){
setInterval("window.status+='x'", 1000)
}
test()
test()
So I call test() twice, which should mean the status bar gets appended 2x's every second. This is the case in IE6 and Opera, but in Firefox, it pauses every 2 seconds, and adds 4x's each time. Basically, Firefox seem to not update every second but every 2 seconds as a result. Anyone know what's going on?
SetInterval To Pass Integer?
Sep 3, 2009function load(cv)
{
setInterval("checknew('cv')",1000);
}
checknew sends the number 1 or 0 depending on what load sends, and in turn, its just alternating 1/0 every second.
I am unsure how to send the number I get in load(cv) to checknew(cv) every 1 second on setInterval.
SetTimeout And SetInterval In Safari
Jun 15, 2009I have a script that I have tried running using both setTimeout and setInterval. It works fine in every browser except safari 3. It will run fine for a few loops and then stop.
View 2 Replies View RelatedPassing Variable To SetInterval
Jul 16, 2007function slide(thisOne) {
var theObject = document.getElementById(thisOne);
var measureTop = parseInt(retrieveComputedStyle(theObject, "top"));
if (measureTop == "0") {
theObject.animationTimer = setInterval("moveObject(theObject, 0, 200, 25)", 50);
} else {
theObject.animationTimer = setInterval("moveObject(theObject, 0, 0, 25)", 50);

I am trying to use the variable "theObject" to pass a value to setInterval.
But I keep getting the error that "theObject" is not defined. But I have tested it with an "alert" just before the "if" statement and I know that not only is it defined, but it has the correct value.
Why won't setInterval recognise the variable? Is there a way to get this to work?

SetInterval Not Running Continuously
Nov 30, 2010I tried putting the method in setInterval in quotations, which runs continuously but it won't allow me to pass parameters so in turn it does nothing. The way I have it now passes parameters but doesn't run continuously.

var icon = this.id;

JQuery :: Can't Get SetInterval Back To Work
Jan 17, 2011In the code below there is a set interval. The interval works perfect. There also is a clearInterval, this one works aswell. When I click on the button with the ID sluitinfonew the interval should be set again, this also works. But offcourse the clearInterval doesn't work anymore because the var is within the function(i'm not sure). Is there a better way to do this? I can't get it to work.[code]
