I have a script that runs a sprite animation on the canvas, adapted from here: [URL] After wondering why it wouldn't work on Safari or older versions of Firefox, I saw this: [URL] and implemented the suggested shim. However, I'm still getting some errors that I can't explain for the life of me. To make this easy for everyone, I threw it in a jsfiddle: [URL]

Please do not take this the wrong way, but rather as a genuine question I have. I do not want to be negative, but the answer to our bug reporthttp[URL]... One of the main reasons we turned to a javascript framework (we used to use prototype before we - migrated to jQuery), is that we wouldn't need to worry about browsers and versions our users use.[URL].. I now notice that I can not rely on jQuery framework for making functions work cross-browser.
In my opinion, if there is an issue with this, shouldn't jQuery intercept and wrap the call to something that does work in Webkit? Again - this is not meant to be negative, but as an end-developer, I think I should be able to rely on same behaviour of all methods provided in the jQuery library, regardless of what browser/version is being used. (or perhaps at least document it in the api docs?)
I have a menu in which is applied typeface script. Typeface 0.11 version doesn't support hover on links. There is an experimental version but doesn't work very well for me, so i tried to implement hover by myself.
Problem is: hover works pretty well changing canvas context property fillColor and then calling fill(), but the stroke on hovered voice remains on another color. Difficult to explain, so i put some test code online: TEST CODE As you can see, passing with mouse on the menu voices triggers the hover and the element change, but remains bordered in red.

I have two select lists that have option lists that are created from external XML lists that contain course offerings available at different locations. Each location has a different set of course offerings. When a user selects a location, the javascript code will hide / show the option entries that correspond to the course offerings for that location. If a user selects a course offering, the javascript code will show / hide the locations that offer those courses.
Click events are attached to each of the Option entries with the code below. The code works correctly with Firefox and Opera, but the click events are never triggered in IE, Safari or Chrome. The Chrome debugger seems to indicate that the click events get set up in Chrome (although I am not sure where JQuery saves event handler data). Each option entry has a unique ID tag.
$(".locn_option_select").click(function (locnevent) { // Set up click action on the option entries
locnevent.preventDefault;[code].......
I'm new to Javascript, and having an issue with getInterval. For my programming languages class we have to create a simulation of waves breaking on a shore from above. I've decided to use a canvas object and Javascript for this animation, but am getting stuck on refreshing the frames.
Here is the code I have so far:
var shoreline = new Array();
var waves = new Array();
var canWidth = 600;
var canHeight = 400;
var waveNum = 0;
var count = 0; .....
As you can see, the idea is that each 5-pixel wide node of the shore and wave are stored in arrays so that the position of each node can differ. The wave() function initializes all the required data, and then calls setInterval on update(). The function update() draws the water, shore, and wave, and then updates the wave position node-by-node. Ideally, setInterval would cause this to happen repeatedly, so that the wave would appear to move closer to the shore every 1000ms.
However, this is not the case. It appears as though setInterval is working for one pass of update(), but fails after the first pass. You can tell that this is happening because the wave appears at its starting position, but does not continue to move. I read somewhere that setInterval can be broken by one-time functions, but I'm not sure. If you'd like to see what it's currently doing in a browser, I've hosted it here [URL]. Once I've got this animating properly I can continue my project, but I've hit a roadblock.
The main one I find is to use translate to move the canvas around, which just seems odd to me. I don't even fully understand how it works. But the one I was looking at used clearRect. In examples given looked as though it had to redraw the canvas every frame. I'm just mucking around with a simple poker game, figured I'd have the table in one layer and anything that moves on a top layer? By doing that I could only clear each card as it moved around...yes?

I have an idea of an interface to allow the teacher to build any type of animation for students using Cake javascript API. I wanted to save the animation build using the canvas element on the rails server either in database or as a file. Later I have to use that animation to be played to students. Any way to do it on any language except proprietary languages like flash but from that language communication can be done with rails server.
View 1 Replies View RelatedNice for a change: a piece of code that does work in all versions of IE, but not in Firefox. I'm stuck.
<img alt="Loodgieters" title="Loodgieters" src="/core/loodgieters_uit.png" name="loodgieters"
border="0" style="margin-right:1px; margin-top:1px; float:left; cursor:pointer;"
onclick="document.location='/pages/loodgieters.php';"
onmouseover="foto1.style.backgroundColor='#392d63'; loodgieters.src='/core/loodgieters_aan.png'"
onmouseout ="foto1.style.backgroundColor='#008ac9'; loodgieters.src='/core/loodgieters_uit.png'" />
Explanation: element "loodgieters" is a menu button that should change on mouseover. It doesn't in FF, it does in IE. Secondly, when you "mousover" the image, it should change the backgroundcolor of a second element (foto1). Element 'foto1' is a table cell. In return, when you mouse-over this table cell, the image element 'loodgieters' should change as well. So it's a two-way thing.
The code for the table cell is:
<td height="189" id="foto1" bgcolor="#008ac9" valign="top"
onmouseover="style.backgroundColor='#392d63'; loodgieters.src='/core/loodgieters_aan.png';"
onmouseout="style.backgroundColor='#008ac9'; loodgieters.src='/core/loodgieters_uit.png';"
style="cursor:pointer;"
onclick="document.location='/pages/loodgieters.php';">
<img alt="Loodgieters" title="Loodgieters" src="/core/loodgieters.png"
style="border:0; margin-left:auto; margin-right:auto; margin-top:10px; display: block;" /></td>

I am new to jquery, and love it so far, but I am more of a designer, not a developer. I am learning jquery to enhance my sites, and I am having a problem figuring out buttons.
I have them working in firefox and safari, but in IE links do not work.
Here is the script I have, and the button code.
Why doesn�t the following code work in IE, I use excanvas.js as told in other articles? excanvas is in the same dir as the html-file.

What I'm trying to do is to simply turn the canvas black and show a small gif on it. Upon executing initCnv(), the canvas turns black as it should, while the sprite image doesn't show up at all. I can't figure out what's going on, I scoured the code for syntax errors, even tried other image formats but to no avail. Image paths are also correct.

I have tried several things, using several Javascript books, but can't get
this to work in Netscape (latest version) and Firefox (latest v.). It works
in MIE and Opera fine. A box (defined by a css layer) is supposed to pop
out to the right when the corresponding box on the far left is moused over.
The first function defines a layer id to the next function which pops out
the box. After debugging in Venkman, it looks like the first function
cannot define the layer id properly to the second function, which actually
slides the box (layer) to the right.
I thought that the getElementById function was supposed to work for Firefox,
but I must be using it wrong(???)
To see how it's supposed to work, view the following page in MIE or Opera:
Found a simple script to show and hide layers. Using this to have an ad with 60px height and onMouseOver 350px
function adtechhideElement(elmID)
{
for (i = 0; i < document.all.tags(elmID).length; i++)
{
obj = document.all.tags(elmID)[i];
if (! obj || ! obj.offsetParent) continue;
obj.style.visibility = "hidden";
}
}
function adtechshowElement(elmID)
{
for (i = 0; i < document.all.tags(elmID).length; i++)
{
obj = document.all.tags(elmID)[i];
if (! obj || ! obj.offsetParent) continue;
obj.style.visibility = "";

but the thing is this doesn't work in firefox/mozilla.
Where should I alter this to get it working in firefox?
The very simple code (below) works fine in Safari (and Chrome, Firefox etc.), but it doesn't work in Mobile Safari. Why?(You can find a working example at: http:[url]....)

Liferay 4.4.2 + jQuery 1.7.1Lib loads correctly (I use noConflict method because in Liferay there is 1.1.4 jQuery). I check for example $('someDiv').hide() and this works correctly.
But .bind() method doesn't work.
I'm trying to create a control which when the mouse button gets
pressed on one div an absolute positioned div pops up in
place of the cursor. From there the cursor should interact with
the dialog before the mouse button is released. In other words
one element will catch onmousedown, display the popup, and
the popup element will catch onmouseup. This works fine in
IE as the popup automatically accepts following events,
but my problem is in Firefox.
In Firefox everything behind the popup
still receive events even though they can't be seen
(hidden by the popup). I have to release the mouse button and then
click on the popup again before it accepts the onmouseup event.
I also used a different cursor on the popup to see if Firefox
recognized it was there at all. Still the cursor doesn't change
until I release themouse button and move the cursor across
the popup element.
I've tried focus/blur, timeout delays, hiding the first element
(the one which receives onmousedown) but nothing works.
The only thing that works is hiding the entire body and then
using setTimeout to show the entire body again 1ms later.
Obviously though that is very ugly.
Following code works.
$('#container a').bind('click', function(e){
log( $(this).text() + ' clicked1');
return false;
});
[Code].....
Windows Media Player, Adobe Reader, etc.
None of these can have events interacted with via jQuery's bind(), although falling back to the native implementations work fine.
I have a submenu that expands over the adobe pdf reader addon/plugin. See this basic exampleI need to make it so that the menu stays above the plugin. Currently, parts of it are cut off.After some research I came across the idea of placing an iframe below the submenu to force it to stay on top. As the topic suggests this is called an "iframe shim" and I have been some what successful. See this basic example one submenu is shown on page load because i plan to take screen shots of it) The only problem is that it doesn't work in opera. I have tested it in chrome and firefox and they are working. I can't test it in ie8 at the moment because the plugin for some reason just won't work on the page, however i have tested the approach before and it did work in ie

I want to delete some lines on the canvas that i have created in HTML5 (with the <canvas> tag).
