Applying CSS Styles To Javascript Rollovers

Jan 19, 2007

Without using CSS styles or linked stylesheets, I need to apply
formatting to text links that use rollover effects.

I can NOT get the underline to show using this technique:

JQuery :: Keep UI From Applying Styles To Elements

Dec 10, 2010

I am very new to jQueryUI and had a question about 1 small thing that has been bugging and throwing me off. Let's say for example, we are creating a dialogue box, triggered to open on the click of a <button>. Once applied, the <button> takes classes such as ui-button, etc, which may end up altering what you want that particular button to look like.

Is there any way to stop jQueryUI from applying this set of classes to the button itself? I have tried using removeClass to strip these, but it doesn't seem to have any effect at all. The styles in my default themeroller theme have been good for everything else, except these small things I don't want altered by the jquery classes. I the model form example, I removed button() from the js and it didn't apply any new styles to the button.

Applying Styles To Returned Node With FirstChild

May 24, 2007

I would like to get the first child of a HTML element and apply a style to it, but I can't figure out how to do it. As far as I can see I can only change its value, and the firstChild only has the following properties, so cant really set a style...

ElementType = bodyElement.nodeType;
elementName = bodyElement.nodeName;
elementContent = bodyElement.firstChild.nodeValue;

Javascript Rollovers

Feb 2, 2004

Im working on my moms website and had this crazy idea to have rollover images for buttons.

The thing is the "mouseover" images seem to just starting to load when you hover over the link which ruins the whole effect.I used different codes, even stuff that was recomended in this forum but nothing works. ok this is what gets me: I uploaded the same page to 2 other servers and my rollovers work just fine there. Code:

Javascript Variables Not Applying Values

Mar 20, 2007

i have the following snippet of javascript:

liChilds[x].onclick = function(){
toggleSubMenu(sub_menu_id, false);
return false;
}

That code happens within a loop, and sub_menu_id has a different value through each iteration of the loop. For example, if it loops 4 times, then there will be 4 onclick functions and sub_menu_id would change for each one. This should happen in theory, but instead, whichever item you click on, sub_menu_id takes the value of its last value in the loop. (4 in this example)

My question is, how do I make the function toggleSubMenu take the value of sub_menu_id at the time the on click function is created (i.e while looping) rather than taking the value of sub_menu_id when it is actually clicked.

Swap Div Styles With Javascript?

Dec 14, 2005

i'd like to have it so that when stream, playlist, etc... are clicked, the button currently using the #activebutton style changes into #navbutton, and the button clicked changes from #navbutton to #activebutton.

Also, clicking the button will change the z-index of a box containing each particular categories content so that it pops to the front, although i have not tried implementing that part yet. (<-- is there a better way to do that? just wondering).

Anyway, i've been trying to teach myself what to do with the javascript. i can get the activate() function to work if no deactivate() function is defined, but it will only work for one button and then that's it. any ideas?

Css Print Styles Conflict With Javascript Precedence

Jul 14, 2007

Basically, I have a div section in my xhtml that I want visible for
print (div {display: block;} in my print css), and visible if somebody
has javascript disabled (therefore also div {display: block;} in my
screen css), but not visible on screen with javascript activated
(i.e., turned off in javascript with div.style.display = "none").

The problem is one of precedence. When displaying the page on screen I
want my non-interactive javascript code to execute after the css rules
have been applied (so I put my javascript within window.onload). But
when a user attempts to print, I'd prefer if the css (for print) were
applied after the javascript. Unfortunately this doesn't seem to be
what happens.

Rollovers..

Jul 23, 2005

I was having a problem with rollovers, even though I do
them in a very conventional way:

function roll(i) {
document[i].src = eval(i + "_roll.src")
} // in which value passed to function is "name" attr in img tag..

but on my home page, www.francesdelrio.com, I have rollovers like this:

function doRoll(Img,newImage) {
Img.src = newImage.src;
Img.width = newImage.width; // what's the point
Img.height = newImage.height; // of these two?
}
function roll_web() {
doRoll(document.web, web_roll);
} // etc.

I'm just trying to remember why I did it like this, it was a solution
given to me by someone in this ng, I believe the problem might have been
that rollovers were not working in Opera (don't have Opera installed
anymore, can't check it out); does this mean all my other rollovers are
not working in Opera? (if you have Opera, can u pls go to
www.francesdelrio.com/resume in Opera and roll over images near top of
page and see if rollovers work? How prevelant is use of Opera? do I
need to always script taking Opera into account?

Rollovers Over A Hotspot

Jul 23, 2005

Is it possible to do roll overs over an area of an image. I know you can
setup up a hotspot but can a roll over be done on that particular hotsop.
Additionally, when the image changes on the roll over, can a certain area of
this new image be shown instead of the whole one?

Why Are My Rollovers So Slow?

Nov 8, 2007

Images are cached by the browser depending on the headers sent by
the server. If the server does not send sufficient information
for the browser to decide the image is cacheable, the browser
will check if the image has been updated every time you change the
src of an image (in some user settings). To overcome this you
must send suitable headers.

Rollovers Not Working In FF/Chrome, But IE Is Okay?

Aug 29, 2009

I'm really new at JavaScript, but I thought an image map with rollover images would be a relatively basic feat... I have a large map with hotspots over individual states. I want the user to hover over a hotspot and for the main image to change, displaying information for that particular state. I've tried code that other developers have sworn works in all browsers, but still can't get the same functionality in FF or Chrome as I do in IE.

<SCRIPT language="javascript" type="text/javascript">
function swapImage(image) {
var Map = (document.getElementById) ? document.getElementById('MapWest') : (document.images) ?

Optimizing Rollovers Script

May 18, 2003

i have the following javascript code:

<!-- hide from browsers that dont support js
if(document.images)
{
about_over = new Image
about_over.src = "images/btn_about_r.gif"
about_out = new Image
about_out.src = "images/btn_about.gif"

success_over = new Image
success_over.src = "images/btn_success_r.gif"
success_out = new Image
success_out.src = "images/btn_success.gif"
}
// -->

and i am using it from within the html code in a standard way:

<a href="about.php" onMouseOver="document.about.src='images/btn_about_r.gif'" onMouseOut="document.about.src='images/btn_about.gif'"><img src="images/btn_about.gif" name="about" width="56" height="23" alt=""></a></td>

question: i don't know much about javascript. i know that the script above preloads the images but i don't understand why the images reference names ( "about_over", "about_out", etc) do not get utilized within html code. it seems to me that they should be used.

Best Code To Preload (not For Rollovers Though!)

Nov 3, 2003

I need a preload script that will load say 5 images...but it need not include any coding for rollovers. I have a site that offers some info to read on the index page...so before going into the main site, and I'd like to use the time that the visitor spends on the first page to preload images that are displayed on the next page. Obviously the goal is to speed up the load-time of "page2," while not making it apparent that it's happening on "page 1" ... does that make sense? Code:

Create Multiple Corresponding Text Rollovers

Dec 8, 2009

i am creating a header for a webpage. the header has two text menus (no images). the first menu (menu A) is like this: link 1a / link 2a / link 3a

the second menu (menu B) is like this:

link 1b
link 2b
link 3b

i would like to use javascript/css to do the following: when you rollover link 1a, three things happen: link 1a changes color, link 1b changes color, and and link 1b adds a line of text (so it reads: link 1b : text 1b)

i would also like- and this is where i am having trouble- for the following to happen: when you rollover link 1b, link 1b changes color and adds the additional text, as well as link 1a changes color.

Dual/Tri/Quad State Rollovers

Sep 13, 2002

I have seen this quesion asked in various forms but the general idea of the question is "How do I make a rollover image clickable". Usually the asker wants to have the image stay on when clicked. Here is a little script that will do that and more..

This is the main code that goes in the HEAD section of your document.

<script type="text/javascript">
<!--
/**
* Dual/Tri/Quad state rollovers from www.javascript-fx.com
* posted at and available from www.codingforums.com
* You may use this code on any website but please
* leave this comment intact.
*/
var img= new Array();
var di= document.images;
var currOn= null;

function Rollover(imgName, imgOut, imgOver, imgClick, imgClickOut)
{
if(imgClick == null)imgClick = imgOver;
if(imgClickOut == null)imgClickOut= imgClick;

var roll = new Object;

roll.out= imgOut;
roll.over= new Image();
roll.over.src= imgOver;
roll.click= new Image();
roll.click.src= imgClick;
roll.click_out= new Image();
roll.click_out.src = imgClickOut;

img[imgName] = roll;
}
function mOver(imgName)
{
di[imgName].src = (imgName != currOn) ? img[imgName].over.src : img[imgName].click.src;
}
function mOut(imgName)
{
di[imgName].src = (imgName != currOn) ? img[imgName].out : img[imgName].click_out.src;
}
function mClick(imgName)
{
if(currOn != null) di[currOn].src = img[currOn].out;
currOn = imgName;
di[currOn].src = img[currOn].click.src;
}
function mSelect(imgName)
{
mClick(imgName);
mOut(imgName);
}
/*** End the rollover code ***/
//-->
</script>


This is the code to define rollovers and is also placed in the HEAD of your document

<script type="text/javascript">
<!--
Rollover("home", "images/home_off.gif", "images/home_on.gif");
Rollover("email", "images/email_off.gif", "images/email_on.gif");
Rollover("script", "images/script_off.gif", "images/script_on.gif");
Rollover("links", "images/links_off.gif", "images/links_on.gif");
Rollover("special","images/special_off.gif","images/special_on.gif");
//-->
</script>


Where the syntax is
Rollover(Name, offImage, onImage);

Then to use the code in a rollover image the HTML in the BODY of your page should look like this

<A HREF="#"
onClick="mClick('home');"
onMouseOver="mOver('home');"
onMouseOut="mOut('home');"><img name="home"
src="images/home_off.gif" border=0></A><br>

NOTE: The name if the image must match the Rollover name
--- <img name="home"
--- Rollover("home", "images/home_off.gif", "images/home_on.gif");

If you use the script in this form you will get something like this demo
Dual State Rollovers (http://www.javascript-fx.com/post/codeforums/quadroll/QuadState2img.html)
------------------------------------------------------------------------
If you want the clicked image to be a third image you define the rollovers as follows :-

<script type="text/javascript">
<!--
Rollover("home", "images/home_off.gif", "images/home_on.gif", "images/home_clk.gif");
Rollover("email", "images/email_off.gif", "images/email_on.gif", "images/email_clk.gif");
Rollover("script", "images/script_off.gif", "images/script_on.gif", "images/script_clk.gif");
Rollover("links", "images/links_off.gif", "images/links_on.gif", "images/links_clk.gif");
Rollover("special","images/special_off.gif","images/special_on.gif","images/special_clk.gif");
//-->
</script>

Where the syntax is
Rollover(Name, offImage, onImage, clickedImage)

Which results in this demo
Tri State Rollovers (http://www.javascript-fx.com/post/codeforums/quadroll/QuadState3img.html)
------------------------------------------------------------------------------------
If you want to have a clicked image and have that clicked image also have a (different) rollover effect you define the rollovers as follows :-

<script type="text/javascript">
<!--
Rollover("home", "images/home_off.gif", "images/home_on.gif", "images/home_clk.gif", "images/home_clk_off.gif");
Rollover("email", "images/email_off.gif", "images/email_on.gif", "images/email_clk.gif", "images/email_clk_off.gif");
Rollover("script", "images/script_off.gif", "images/script_on.gif", "images/script_clk.gif", "images/script_clk_off.gif");
Rollover("links", "images/links_off.gif", "images/links_on.gif", "images/links_clk.gif", "images/links_clk_off.gif");
Rollover("special","images/special_off.gif","images/special_on.gif","images/special_clk.gif","images/special_clk_off.gif");
//-->
</script>

Disjoint Rollovers With Image And Text

Aug 9, 2006

I am trying to create some rollovers using the following scenario. I have four groups, letís say hearts, diamonds, clubs and spades. Each of these groups have a varied amount of members. For each group, there is a short description of what the group is supposed to do, and then thumbnails of each of the members.

To the right of the thumbnails is an image that holds a standard image, but would change to the enlarged picture of the member when the mouse is over the member's thumbnail, and below that image is another area which will hold the person name and position if any within that group. Basically there are four rollover groups. I can do the rollover for an image okay as in this code, adding more variables and images as necessary using something like this. Code:

Rollovers Plus Onclick Image Swaps

I am not very well versed in js, but am attempting to figure this out. (Gotta start somewhere, right?) I want this to be unobtrusive js, if possible with no js specifics in the html (though additional or changes to classes/IDs would be fine). I've started with PPK's mouseover script, which is working just fine. To this, I want to add some onclick behaviors. Code:

Multi-dimensional Arrays With Image Rollovers

Aug 9, 2006

I'm trying to get rollover images to work that are a little more complex than usual. I have a webpage that presently gives information on four groups within an organization. I've put each group within its own div with an id. The div contains a short description of what the group does, thumbnails pictures of each member of the group, and to the right of these thumbnails, a larger picture. This larger picture is supposed to change, when ever the mouse is over a thumbnail to a normal size picture of the thumbnail, for the first part.

I tried to put in a script that will preload all the original images that should be changed. First I created an array with all the names of the divs, then used two for loops, one nested inside the other to get the pictures into the array. Tried to get the names of the array to hold the pictures from the first array with the names (inames), using a two dimensional array (used an example from a post on this forum) but it seemed to have gone astray, as the onmouseover doesn't work. Code:

Set Up Products Page With Swatch Rollovers And Detailed Views?

Nov 3, 2009

Ultimately I'd like a set up resembling http://shop.lululemon.com/Swift_Tank...30/p/1230.html

Where you're able to click a swatch color and get a thumbnail of it on the model and a thumbnail of a fabric detail that you could then enlarge. I'm not sure how to go about this. I'm able to do it with one thumbnail, where when you rollover the various swatch colors, the thumbnail of the model gets replaced. However I'm unable to add in the 2 other thumbnails (on that site they're using 3 but I would only need 2) that would change at the same time, where you could switch back and forth from at detail of the model and the fabric.

I don't necessarily need the zoom function, but if it is possible to do all of those that would be good too.Otherwise I just need help coding how to at least get the swatches to change 3 images upon mouseover and that 2 of those images would be like the 3 thumbnails on the link above and would replace the larger thumbnail once clicked.

Show / Hide Button That I'd Like To Change Text & Add Rollovers

I have a button on the left, part way down that says "show/hide resume" How could I.

1) make the text read either "show" or "hide" when the button is clicked?
2) put a rollover effect on the button (simple text-shadow)

I've tried finding tutorials, but they are all for other types of buttons (submit, etc)Should I be using a different type of button?

JQuery :: MIT-Licensed Solution To Image Swaps And Disjointed Rollovers?

Jan 19, 2011

Does anyone know of a good MIT-Licensed, or MIT-style image swap and disjointed rollover solution? All the ones I've seen are either GPL or personal-use only. The examples of img replacement scripts I've seen on stackoverflow are either only for personal use (I believe every example on the site is personal only, unless stated?), or too narrow in scope.

Any help would be great as the docs.jquery.com site has great demos on almost everything except how to swap images. I don't mind if its a block of code or a plugin, although preferrably something small and simple would be great.

It sounds like a big ask, but I thought I would ask as this place is super-friendly, unlike some of the other js libraries' forums' I've been to.
