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?

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.

I have a website that contains a large div inside a smaller div, only to be scrolled via javascript. The problem is when you mouseover the smaller (container) div and you scroll the mousewheel down, everything scrolls down.

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?

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?

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?

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.

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.

get an image scroller by dragging of the mouse (like you have with Google maps for example).Right now I'm using a script that does the job perfectly fine under IE, but not so much under FireFox, and definitely not under Chrome.
Here's a hands-on example of what I mean (only works under IE): [URL]This is the script I'm using now:

<!-- <script type="text/javascript">
document.onmousedown = function(){
var e=arguments[0]||event;

I have a JavaScript routine that runs on a timer and updates the position of a
background image using the CSS background-position property. In Internet
Explorer, it changes the mouse pointer to an hourglass when it refreshes the
screen, and this is really annoying since it happens on the timer, about every
100 milliseconds or so. Is there anything I can do about this?

I'm trying to find a javascript based spinning wheel for page loading. I'm hoping that it would be something that would hide the content until the content is finished loading.

jQuery - Scrolling browser Window. I have two demos of scrolling page content with jQuery.
This one - [url] is scrolling the contents inside a container and it works as I wanted on Mac/PC
Code:
I need the same effect as above but I need to scroll the whole browser window.
I have a demo here - [url]
Code:
Problem here is on the Mac the transition are jumpy and it seems to flash the first yellow div before sliding up or down. Testing on a PC it will slide down but won't slide up. How can I get the whole browser window to slide up and down with a smooth transition.

im searching for a plugin/code example for text scrolling. I got some text in a <div> if text is longer than for example 300px it gets cut and is scrolling from start to end, stops for a second and then scrolls back, stops and all over, and if its not long enough than 300px then just displays normaly. Something similar to the Song name scrolling inin anyMP3 player.

I've got a bunch of <div> blocks, with a fixed width and height, that are all left floated.I would like a user to be able to click a "remove" link and have it delete a box, and all the boxes to the right "slide in" to fill the void created.I have it working well enough with a "snap" transition. I made that term up because I'm not sure how else to describe it--by "snap" transition I mean that the boxes to the right "snap" into position--there's no "sliding" or easing as they move, it's just moment their in their old positions, and the next moment, everything has been rearranged and they're in their new positions. how to adequately describe it in text, so here's a video showing what I mean: [URL]

my indexof() function is not being recognized when I enter an email address for an unsubscribe form I have on one of my pages. Additionally, the confirmation message is also not showing up when the email address IS valid. Here is my code that I am using on a PHP page:function Unsubscribe() {
var IsValid = document.getElementById("email").value;
alert(IsValid.indexOf("@"));
exit;
[code]....
to those PHP experts, I am aware of the RegEx function for validation, but I don't understand it, which is why I don't use it (in case anyone points that out).The other thing that is problematic is that the PHP code is automatically using HEADER() regardless of "email"'s value

I was just wondering if it's recommended to have all your javascript contained in a single unified block or if it's okay to have them spread out across the document? I find the second approach ensuring JS is located near code that is directly associated increases readability, but I'm worried it may have a negative effect on performance, however minor.
