I have develop this javascript code [URL] This is a simple carrousel. I´m using JQuery 1.3.2. In the code you can see an array with images and the code is simply
changing the source of the img with the ID "carruselimg". I´m getting "too much recursion" y FF3 and "out of memory" on IE7 when this page is about 15 mimutes working.
First the code:

When I use mouse wheel in Firefox to scroll contents of the DIV, memory usage in Firefox goes through the roof. Code above is a fully working page, if anyone would like to see what's up, just load it up, and start moving your mouse wheel in the area with text. You don't actually have to scroll the text, just moving the wheel back and forth in that DIV will do. Memory usage will start going up quite fast, and after you stop moving the wheel, it will finally come down a bit after a short while. I've highlighted in red the line where mousewheel event is registered for Firefox. I'm not sure if it's really a problem, but since Opera and IE don't have any strange memory usage, and Firefox does, maybe I did something wrong. In everyday use it shouldn't matter [don't expect to have kilometers of content to scroll], but anyway, it is a bit unsettling.
wanna know how we can get the animation effect using the recursion method. following is the code:
$(document).ready(function(){
$(".flip").click(function(){
$(".panel").slideToggle(2000); // i wanna call this jquery animation recursively

View 2 Replies View RelatedI am having a problem finding the syntax for recursively adding images to a webpage using javascript. I have some pseudo code but no js.
already in a folder function 1 for each file in folder add file to webpage next folder function2 function2 for each folder within folder call function 1
I know the code isn't all that clear, but that's the best way I can describe it.
I am having trouble with a recursive function I created to list out the indexes and values of various nested objects.
var macros={
CTRL: {
ALT: {
ENTER: "<br />",
P: "<p>.</p>",
A: "<a href="">.</a>",
_1: "<h1>.</h1>",
_2: "<h2>.</h2>",
_3: "<h3>.</h3>",
_4: "<h4>.</h4>",
_5: "<h5>.</h5>",
_6: "<h6>.</h6>"
}}};
I want to print out the whole 'bread crumb trail' to each object, ie CTRL ALT 6: <h6>.</h6>, but at the moment my function prints out CTRL ALT twice for 'ENTER' and then never again. The function:
function printObj(obj) {
for(i in obj) {
var n=i.replace("_", "");
document.write(n);
if(typeof obj[i]=="string") {
document.write(":");
document.write(" "+obj[i].replace(/</g, "<").replace(/>/g, ">"));
} else {
document.write(n);
}
if(typeof obj[i]=="object") printObj(obj[i]);
document.write("
");
}}
printObj(macros);
The current output:
CTRLCTRLALTALTENTER: <br /> P: <p>.</p> A: <a href="">.</a> 1: <h1>.</h1> 2: <h2>.</h2> 3: <h3>.</h3> 4: <h4>.</h4> 5: <h5>.</h5> 6: <h6>.</h6>
I am using the module pattern and private/public methods. I'm having a problem where the private method is using setTimeout() to call itself recursively, but I can't get the syntax right. Code:
View 1 Replies View RelatedI have this script. It's supposed to give the Fibonacci numbers but the recursion won't work. It just prints out 1 number that the user entered and that's it. In IE6 it prints 1 number but in Firefox it prints the same number an infinite number of times. Whats going on? Here is the script:
<html>

<script language = "javascript">
function fib(form)
{
var fibVar = Number(document.myform.inputbox.value);
document.write(fibVar);
if(fibVar == 0 || fibVar == 1)

I am using jQuery form plugin to submit my form. It has a file element and when where I am submitting it I am getting "too much recursion" in Firefox. It looks fine in IE 8. It works fine if I submit the form without selecting any file.
I am calling ajaxForm() methid this way.
jQuery("#myForm").ajaxForm();

What happens there is a memory leak of the divs with idsliveAuthen-target-1000 andliveAuthen-content-1000
It is possible to remove a function from the memory? I have a custom function that I call usingmodul.StepGuide.init() - but how do I remove that function with all its vars and events, from the memory.
View 1 Replies View RelatedI have started using jQuery recently and I am having a problem with IE leaking memory when performing a $.getJSON() request at intervals. To test the problem I set up the code to run every second. The only code I currently have running is the ajax request as below:
getDetail = function(detailID){
$.ajaxSetup({ cache: false });
$.getJSON("api/urlgoeshere", {"dID" : detailID,"d" : 0},

If I leave the above running the Memory Usage climbs by about 5mb a minute in IE but is ok in Firefox. I am using jquery-1.4.2. Has anyone come across this before?
I have a table, 10 cols, 200 rows. Using tablesorter causes a memory leak on every page refresh of almost 2mB. A smaller table causes a proportionately smaller memory leak. Is there way to clear this memory? I've tried setting inner html of the table to '', but it makes no difference. Is there even a universal method i can call to remove any trace of any jquery plugin I have on the page?
View 3 Replies View RelatedAttached is a sample html file (named jqmleak.html - rename it to remove the txt extension and drop it into your web server to test for yourself) that I've put together to demonstrate a memory leak with the $.ajax function in jQuery 1.6.1 when run in Firefox 4.0.1. The file loads jQuery 1.6.1 from the Google API CDN. Next, a simple function is defined that runs $.ajax to request the html file itself. This function is then set to run once every second using setInterval.
In Firefox 4.0.1, on both Win XP and Linux (ubuntu 10.10, 64-bit), I can watch the amount of memory consumed by Firefox gradually rise. It takes a few minutes for the problem to be observed, because initially the memory will decrease with no other activity in the browser. Then after about 5 minutes or so, I can watch the memory used by Firefox slowly but steadily increase. I can use the handy 'about:memory' tool in Chrome to monitor this alongside other browsers. Chrome, Opera, and IE do not exhibit the same problem with this test. Their memory usage will vary within a range of about 2 or 3 mb, but over a long period of time they do not increase their total amount of memory used. This problem is only happening in Firefox 4.0.1 as far as I can tell (I also used safe mode in Firefox to make sure no plugins were interfering with the test). I have tried both GET and POST methods with the $.ajax call, and with the cache setting both enabled and disabled. The result is the same.
Is this a jQuery problem, or maybe instead a bug with Firefox? I see similar bugs reporting memory leaks in other situations, but usually specific to IE. I was about to report a bug for this, but I thought I'd check here first to see if anyone can duplicate this problem, and/or point out what I should do to prevent the memory leak in Firefox.
I have a jquery based system with ajax calls instead of page refreshes. Every time I return some ajax content, it replaces the content on the main div.
function execcmdcallback(data, textStatus, XMLHttpRequest)
{
$("#divmain").html(data);
data = null;
}
Each time this executes, the browser memory increases by about 600-900kb. Can anyone suggest a way of doing this where the old memory is freed so there is no significant increase in browser memory on each ajax call ?
I've studied this a bit, [URL]..., but I have to admit I don't quite understand it I see the same issue on IE8, FF and Chrome. FF comsumes less memory per ajax call and frees some memory seconds later, but still the total working set is increasing on each call by 300k in FF and 600 to 900 in chrome and IE
I'm currently trying to code a jQuery base memory game for school. I however got one problem right now. The cards are supposed to change picture on mouseover and change back on mouse leave. However, if you click on a picture, that card isn't supposed to turn back right away. I thought I could fix this with classes, but it doesn't work. Here's a part of the code:
$(document).ready(function() {
$("img.spelkort").mouseover(function() {
$(this).attr("src","spelkort/kortbaksidahover.jpg");
$(this).addClass("hover");
});
$("img.spelkort.hover").mouseleave(function() {
$(this).attr("src","spelkort/kortbaksida.jpg");
$(this).removeClass(".hover");
});
$("img.spelkort").click(function() {
$(this).attr("src","spelkort/kort1.jpg");
$(this).removeClass(".hover");
});});
I have a code for the keydown event:
-when you press the UpArrow key the image moves up
-when you press the DownArrow key the image moves down.....and so on
But don't forget that this is under the keydown event...so when I keep pressing the UpArrow key the image moves up but when I release the key the image still moves up. I already put the code $('myImage').stop(); on my image on keyup event but this doesn't do anything. There is a code to clear my memory from pressed keys or something?
Working on creating my own plugin and realized that I would very likely end up doing this again in the future. Unfortunately, I have an extremely short memory when writing code. I frequently have to re-read the code I've created the day prior so I can get back on track with what I was doing. As such, I'm a fervent commenter in my code.
So, I'm creating a jQuery plugin framework with comments for everything that's going on in the framework to prevent my brain from having to re-learn everything in a month or so when I do another one.
Plugin-savvy folks to take a look at this code and help me fill in the blanks and make corrections to those places where I'm way off base. As you'll likely notice rather quickly, this is taken from the jQuery plugin tooltip construct found here: [url]
I need help with this code. its a counter.
var count= 0
function onm() {
atextbox.value=ffee
count++
setTimeout(onm(),100)
}
And in the body:
<body onload="onm()">
<input type="text" value="0" name="atextbox">
</body>
I get always an error: Out of memory
I've been putting together a small pet project. Once it was finished i realised it had a gigantic memory leak inside of it. I tried to read up on the subject, but couldn't find the source of the problem via the articals.
This site is very simple, so I'd think idenifying (and hopefully fixing) the problem would be easy. Here is the relavent portions of JS (followed by links to the full page incase you need to see that): Code:
I was wondering how good is JavaScript with memory management. I have
an object called MANAGER that has a list of other objects, each one
managing a single DOM nodes, etc. In my implementation of
MANAGER.reset(), I simply recreate my MANAGER.object_list = new
object(); and do a single MANAGER.domnode.innerHTML = '' as apposed to
getting my hands dirty. Is my app leaking memory?
Internet Explorer leaks memory when I update a div container using
innerHTML, this does not occur in firefox. This would not be a problem
except the webpage is required to be left on for weeks on end without
being restarted. I presume the issue with innerHTML is that Internet
Explorer apparently parses what you give it and then decides on how to
construct the dom elements itself, so never truely creates what you
give it.
I know that the innerHTML is the problem as I have successfully
narrowed down the leak to that line. It only leaks memory when I assign
content to the innerHTML of my containing DIV. Appending a text node,
for example, with the exact same information to the same div does not
leak. Note I have also tried using such existing AJAX packages like
Prototype etc. but to no avail.
I need to do it this way as my XML documents are styled using an XSL
stylesheet and then transformed using transformNode [I will omit
details regarding firefox as there is no problem there]. I have looked
into transformNodeToObject as a way to get a dom object that I
originally assumed could be appended [as a child] to my containing
element. This did not work and gave me compatibility errors.
I suppose I am either looking for someone who has solved this problem,
or who has an acceptable work around. Or someone to say that it cannot
be solved.
I am using javascript to load and parse a big xml file (around 1 mb) save some values to an array and draw a picture using google Flot. Unfortunately, this causes the browser to crash! Is there a way to clear the memory of the browser?
