Memory Leak - When Use Mouse Wheel In Firefox To Scroll Contents Of The DIV - Memory Usage In Firefox Goes Through The Roof

Mar 26, 2009

First the code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8"/>
<title></title>
<script type="text/javascript">
function TextScroll(scrollname, div_name, up_name, down_name, top_name){
[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.

Getting Mouse Wheel Focus Even When The Mouse Isn't Inside The Overflowed Div?

Jul 8, 2010

I am finishing up my website, right now I am using Flexcroll for the scrollbar in my main content window. Problem is, I want people to be able to use the mouse wheel to scroll that content window regardless of the mouse position.

My website is www. paulfenton .tk/wordpress if you want to see it.

I was wondering if anyone knew a way I can keep the mouse wheel focus on that internal div so I can scroll up and down at all times.

Removes Default Drag Behaviour On Image In Netscape

Jul 23, 2005

I am trying to implement a rubber band/image selection script. For
that I need to remove the default drag behaviour on an image. I am
able to do this in IE but not Netscape. Does any one have a solution?

Pls look below for IE code:

var moz = ((document.all)? false : true);
var ie = ((document.all)? true : false);
var ElementUtil = new Object();
ElementUtil.addEventListener = function(o, type, handler) {
if(ie) {
o.attachEvent("on" + type, handler);
}
else if(moz) {
o.addEventListener(type, handler, false);
}
}

// Removes default drag behaviour on image in ie
ElementUtil.addEventListener(img, "drag", function() {return false;});

Scroll A Div With Mouse Wheel?

Oct 27, 2009

I have been searching google for a solution to this, but I am having trouble finding something that works.

I simply want to be able to scroll the contents of a div (with no scrollbar) using the mouse wheel. The div should only scroll if the cursor is over the div when the wheel is moved.

Does anyone know where to find a good working solution to this?

Disable Mouse-wheel Embedded Pdf Document

Apr 27, 2011

I am not an expert in javascripting, so forgive me. What i am trying to do is disable embedded pdf documents from being scrolled up and down with the middle mousewheel button on the mouse.I am using embedded PDF files as a way to easily display reports through a browser (FireFox). The actual PDF is about 10 pages long, but the HTML page is coded with the embed tag and uses the Open Parameters to display just a few aspects of the PDF, in an easy to read format. The annoying part is that the embedded PDF sections can accidentally be scrolled with the mousewheel, which ruins the look of the report in the browser. Is there a way to disable this?

As you can see in the first div, i was trying to use javascript to disable the mouse wheel, which did not work. Since each div is a snapshot of the embedded pdf file, is there a javascript that can disable the mousewheel scroll for each section by placing it in the body tag?

Mouse Wheel Listener Blocks Scrolling

Jun 1, 2011

Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<img width=100 height=9000>
<script>
document.onmousewheel = function()
{
[Code]...

First of all, my code only needs to be compatible with IE8 (it's for a limited group of people). My code is intended to detect the rotation direction of the mouse wheel. It fortunately accomplishes that task perfectly fine. But unfortunately it also blocks the mouse wheel default behavior, which is not my intention. How should I change the code so it does not block normal scrolling of the page with the mouse wheel?

Cross Browser Mouse Wheel Event Handler

Oct 8, 2005

I'm trying to write a cross-browser (IE and firefox) event handler for
the mousewheel. Basically my web app is an image viewer, so if you
scroll "down" with the wheel the next image should be displayed and if
you scroll "up" the previous image should be displayed.

So far I have:

function handleMouseWheel(e)
{
if (!e) e = window.event;

if ( e.wheelDelta <= 0 || e.detail > 0) { changeImage(1); }
else { changeImage(-1); }
}

This code works in IE and in Firefox to the desired effect. The
problem I am having is with registering the event handler.

The following works for IE:
document.onmousewheel = handleMouseWheel;

And the following works for Firefox:
window.addEventListener("DOMMouseScroll", handleMouseWheel, false);

But when I add the firefox event handler to my code, IE chokes with an
error "Object doesn't support this property or method".

What do I need to do to "hide" the firefox event handler code from IE?

Jquery :: Possible To Have Mouse-wheel Call Event On Slider?

Dec 6, 2009

I have a jQuery UI slider plugin working to scroll some content. I would like to add a mousewheel event. I have this installed and have it working with a small hack. My questions is, is it possible to have the mousewheel call the event on the slider? This way, when you move it with the mousewheel, it just moves the slider which will scroll the content.

Stop DIV From Following Mouse On Keypress?

Apr 8, 2010

Ive scoured the internet for scripts that make a <div> follow the mouse, and have found one that seems to work well. However, I want the <div> to stop moving when the CTRL or the SHIFT key is pressed, I dont care which. Hopefully, I can have a div that follows the mouse at an offset that contains some click-able items, so a menu is always by your mouse. Ive tried now more than a few times to put together a piece of code that can achieve this, but none have worked. Can somebody write a script that can achieve this, or point me in the right direction?Current JS for mouse follow:

var divName = 'mouseFollow'; // div that is to follow the mouse
// (must be position:absolute)
var offX = 15; // X offset from mouse position

[code]....

JQuery :: Compensate For Mouse Position If Page Is Re-sized From Default?

Mar 16, 2010

I am using mouse x,y onclick in one div (if mouse is in one set of coordinate range) to determine whether or not to show/hide another div, and am stumped as to how to compensate for the user changing page size, as the coordinates change. Is there an absolute xy, regardless of page/text size, or code to compensate for it? What is going on here is I have flash that I have no control over (wix) and I need to show Html (which wix doesn't), so I am having to determine if the user is over a certain button in the swf which I put in a div to give me some control over the flash. I'm using on click to bring the HTML to the front in a certain position, while the flash does its animation thing.

Prototype And Firefox - Create New Default Right Click Behavior?

Feb 3, 2010

I have a table (tables are for tabular data) with patient information. The user can click the row to select it and when they do the right part of the interface loads some additional information on the patient - quick lookup info if you will, but also provides links to tasks involving that information - edit, view case history, etc.I'd like to replace the default right click behavior on the rows to create a pop up menu next to the point of click that links to the same list of options for the convenience of the more savvy users.The project is being built with prototype so no jQuery please. The site is a corporate intranet where Firefox is the only browser it is *required* to work in. It would be nice to have it work in webkit.

Mouse Position In Firefox

Jul 24, 2005

I have a bunch of links that when you mouseover should bring up a window with extra information. The links look like

Code:
<a href="#" onMouseOver="popInfo(this)" onMouseOut="unpopInfo(this)">Link Text</a>
Here's the code for the tw functions, popInfo and unpopInfo:

Code:
function popInfo(x) {
var posx = 0;
var posy = 0;
if (!e) var e = window.event;
if (e.pageX || e.pageY)
{
posx = e.pageX;
posy = e.pageY;
}
else if (e.clientX || e.clientY)
{
posx = e.clientX + document.body.scrollLeft;
posy = e.clientY + document.body.scrollTop;
}
var infoBox = x.parentNode.getElementsByTagName('div')[0];
infoBox.className = 'infoBoxHover'
infoBox.style.left = posx;
infoBox.style.top = posy;
}
function unpopInfo(x) {
var infoBox = x.parentNode.getElementsByTagName('div')[0];
infoBox.className = 'infoBox'
}
This is working perfectly in IE and Opera but in firefox it's saying that window.event has no properties. I don't know much about javascript so I don't know where to start. Some help would be great.
