Onmouseover Image Not Loading In IE - Firefox Or Opera
Nov 6, 2009
I am experiencing a problem with some images I am using for navigation. In Safari on my Mac everything displays as it should. The image loads ok, I mouse over the image and it goes black and white, mouse out and it goes back to colour.
When I tested this with Firefox and Opera on my Mac and IE8 and Firefox on my Windows laptop the onmouseover image does not appear and I am left with a text link and a lot of flickering as you move the mouse about.
I have almost zero knowledge when it comes to javascript and I've got the necessary code which according to everyone works from either books or the web.
I am completely stuck as to why this simple operation is not working.
you can see the page at this address: [url]
Only the left hand image has been set to onmouseover as I was testing to see if it worked first.
I have attached the CSS and HTM files in a zip file.
I use DIV tags with onMouseOver action on the DIV-s. I want to download and show a photo if an onMouseOver activates. This is simple and works but there is a problem.First time I move my mouse cursor on the DIV the photo doesn't appear, only its border. When I move the mouse off and back again, the photo appears right. I want to show the photo first time well.There is a solution: preloading images with JavaScript invoked with the onLoad event of the BODY tag. But I would have numerous (100+) photos, so it's a bad idea to preload all the photos (and users usually want to see only a few, not all of them). It is acceptable to wait a second or two after activating onMouseOver while the photo is downloading but it's not acceptable to do TWO onMouseOver actions for a photo
What it is supposed to do is pull down the background image of my nav panel by setting the CSS height to match the length of the page. I got it to work in IE but it does not work in Opera or Firefox. I'm not sure how to access the correct object in Opera and FF.
To view the problem:
Well, I'm a new user so I can't post the link to the problem.
I've been working on a project for some time now, and just recently I installed Firefox.
Now, part of the site (which works perfectly in IE6/7) doesn't work in Firefox.
Here is part of the code:
(I didn't copy all of the code because it's basically the same all the way down) The main problem is with the link (Firefox apparently doesn't recognize table rows as links).
The second problem is with the onmouseover/onmouseout etc handlers (absolutely nothing happens).
Just in case you need to know, the code is for a nav bar.
I have used JQuery to change CSS styles for my Navigation Bar elements.Ok so after a bit of research I discovered that " background-position-y " and "background-position-x" are not supported by the Mozilla Firefox / Opera browsers.Anyone know of an alternate method of getting the background-y / x positions?
Setting maxlength attribute of input[type=text] or input[type=password] does not work as expected.In Firefox and Opera if maxlength is not set the field.attr('maxlength') == -1. But if I try to set field.attr('maxlength', -1) it is being set to 0 instead.
It works fine in Firefox and Google Chrome but not in Opera and Internet Explorer.If you don't have Firefox or Google Chrome,when you click an element, if should be lighter green, rolling out of a clicked element, it should be darker green. The same happens with elements that are not selected, ubt they are gray. But in IE and Opera, when you roll out of a selected element, it is gray.I can't debug it in Opera because I have no debugger there, like Firebug.
I am using the lightbox script from "Jquery:Novice to Ninja" and it works very well in Firefox and Opera but not in IE8.
The problem, I think is because I am using PHP to pull the picture names from a file. There are around 40 pictures so I didn't want to name them all manually.[code]...
This easily produces a nice page of thumbnails and clicking on any brings up the bigger picture in lightbox but not in IE.
It seems that IE needs another set of pictures to load from so the filename od the <a href=image> needs to be different to the <src=image> filename which makes more work.
Is there a work around to make this work as well in IE as it does in firefox.
The page can be seen at[url]
Also as an aside. When the lightbox starts it removes the scroll bar which has the effect of moving the page to the right. Is there a way to add a right margin to replace the scroll bar to stop this happening?
I have a web page, in a frame set, that has a table-menu bar in javascript. It relies on the "movein" function attached to "onmouseover" to trigger the chaninging of the elements background color, text color, and pointer when the mouse moves over an element. On IE the code below works fine. In firefox none of the movein function doesn't seem to be triggered (none of the above effects occur) UNLESS I force a reload of the frame. Then everyting works fine. Any ideas? Code:
Stumbled onto this one: retrieving the margin doesn't seem to work in Firefox or Opera. This is code I'm using, which works fine in Chrome, Safari and IE:
var contentmarginl = parseInt($('#wrapper').css('marginLeft')); // fails var contentwidth = $('#wrapper').width(); // works alert(contentmarginl);
The alert returns (in my case) 350 in the complying browsers and 0 in FF and Opera. Is this a bug or my error? Is there a known workaround? EDIT: Just tested in XP sp3 IE7 & IE8. Returns Not a Number (NaN)
It does NOT work fine in IE8 or Safari. In both these browsers the height of the DIV that's being set is usually shorter than the other DIV it's being aligned with.Here's the code I'm using to resize the problematic DIV:
Function resize(height) { $(document).ready(function(){ var div = $( "#annoucement-area-243" );
I have a frame set (as per MS FrontPage 2000). It has a contents and a main frame. The contents frame has a menu bar written with with javascript (in the context of a table). In IE6.1 everything works fine as it also does in firefox if I call the contents frame directly (i.e. outside of its frameset). However, if I call my main page (index.html) which invokes the frame set, the contents frame javascript menubar onmouseover function doesn't seem to work though if I reload the contents frame directly it then does.

I am not a guru jquery coder and still have to learn alot, recently while learning jquery AJAX I have bumped into a weired issue, I have a apge right and in this page I have a dropdown list for people to select an RSS channel that they wish to know more about, the dropdownlist ahs an onChange event which when triggered it will get the value of the selected item in teh dropdownlist and post it to the other 'mini' pages that load on the same page via AJAX by using the GET method - ie: im passing the parameters like a normal querystring would. The problem is that when I assign the dropdown value to a variable called dropdown in the following line of code "var dropdown =document.getElementById('ddlChannelSelect');" it works in IE but not in the other browsers, I have debbugged this in FireBug and it seems that the variable dropdownlist is not actually getting the value of the actual dropdownlist nad it says 'null' or sometimes 'undefined'. Am I doing something wrong ? why is it that it is working in IE but not in other browsers ? can you pls give me a solution with some examples ?
The minimal AJAX script below works in Firefox, but not in IE, Opera, or Chrome.I could use some suggestions or referrals to resources that will help me get the script working in other browsers.Before there are six characters entered in the CAPTCHA code field, the 'Send' button is supposed to be disabled. When there are at least six characters in the CAPTCHA code field, the script attempts to verify the CAPTCHA w/AJAX. If it verifies, it enables the Send button and sets the background of the CAPTCHA code field light green (symbolic for go). Otherwise, it turns the background of the CAPTCHA code field a sort of pink/red (symbolic for no go). While it's waiting for a server response the background is set to a pastel yellow. At other times, the background of the code field is white.
I'm having a problem with .attr(). I will explain it whith code.I have this HTML code:
<p id="textoMarca0" onmouseover="muestraDialog('textoMarca0');"> this is an example paragraph </p>
[code]....
So now the onmouseover has again its value [the original one, copied by doing an alert($("#"+elem+i).attr('onmouseover')) when i disable the onmouseover event], but it doesn't work
I have a list of links to PDF articles, each link has a corresponding div that contains an introduction to the article. I'm using the onmouseover event in each link to show the corresponding introduction div and hide all the others.
The order and number of the pdf links and the introductory divs are the same. The code below works in IE but not in FireFox - the problem in FF is the index returned from the onmouseover event is double what it should be, so the first PDF link shows the second div, the second PDF link shows the fourth div ect.
Im trying to enlarge an image using onmouseover but im trying to keep the image in the same central position eg. The image increases in size from the middle out rather than the top left corner staying in the same position (as in my code). An onmouseout setting the image back to the original size.
