JavaScript - Need Help With Mouseover Script
Good morning all,
I am trying to write a JavaScript that performs the following action: When I roll my mouse over on a paragraph with a Code: <p class="hover-target"> Paragraph goes here</p> It will do a reverse video of it. Currently the web page is in white background, black text. So when the mouse rolls over that particular paragraph it will be a black background, white text for that paragraph only. The JavaScript I wrote is: Code: {
Core.start
(
( function()
{
function mouseoverListener(evt)
{
evt = evt ? evt : window.event;
core.addClass (this, " over");
}
function mouseoutListener(evt)
{
evt = evt ? evt : window.event;
core.removeClass (this, " over");
}
return {
init: function()
{
var allElements = document.getElementsByTagName('*');
for (var i = 0; i < allElements.length; i++);
{
if (core.hasClass(allElements[i], "hover-target"))
core.addEventListener(allElements[i], 'mouseover', mouseoverListener);
core.addEventListener(allElements[i], 'mouseout', mouseoutListener);
}
}
};
}
)()
);
}
The HTML document has the right path to the scripts (core. js and the rollover.js) as well as the stylesheet (index_style.css). Also, the CSS stylesheet code is: Code: .over{
color:white;
background:black;
}
There is more to this stylesheet but I am only highlighting the rollover style. Am I missing something from my code? Thanks for your time. Similar TutorialsHello everyone, 1.) I'm not a programmer beyond HTML, CSS and only a basic knowledge of javascript, it doesn't take much for me to get lost beyond my skills in javascript. 2.) Is someone willing to add and explain the changes to the code below to include a pause on mouseover? Code: var currentSlide = 1;
var maxSlides = 0;
function fadeImage(){
opacity = 100;
if(steps < 4){
steps += 1;
opacity = opacity / steps;
imageObj = document.getElementById("slide-"+currentSlide);
imageObjN = document.getElementById("slide-"+nextSlide);
imageObjN.style.display = "block";
imageObj.style.opacity = "" + opacity / 100;
imageObjN.style.opacity = "" + ((steps * 25) / 100);
//fade
slideTimeout = setTimeout("fadeImage()", 170); /** fade transition speed */
}else{
steps = 1;
document.getElementById("slide-"+currentSlide).style.display = "none";
currentSlide += 1;
if(currentSlide > maxSlides){
currentSlide = 1;
}
showSlide();
}
}
function initSlideshow(){
slidesCollection = document.getElementById("slides").children;
maxSlides = slidesCollection.length;
for (var i=0; i < maxSlides; i++){
slidesCollection[i].id = "slide-"+(i+1);
if (i > 0)
slidesCollection[i].style.display = "none";
}
steps = 1;
nextSlide = 2;
slideTimeout = 0;
showSlide();
}
function showSlide(){
clearTimeout(slideTimeout);
nextSlide = currentSlide + 1;
if (currentSlide >= maxSlides){
nextSlide = 1;
}
slideTimeout = setTimeout("fadeImage()", 8300); /** display time of slide */
}
I know this maybe sounds "newbie", perhaps I am still one. I have 3 divs, all of them in a group "name", there are h1 tags inside them with names too. Well actually I have many many divs like this in several pages so I must use a JS sheet (.js). Code: <div name="area"> <h1 name="stringRed"> Mercury </h1> </div> <div name="area"> <h1 name="stringRed"> Venus </h1> </div> <div name="area"> <h1 name="stringRed"> Earth </h1> </div> The idea is to create an event for the divs, a mouseover event to a div in order to change the color of the words inside the h1 tags. When the mouse is over one particular div the word inside it must change to red. I was trying this Java Script script: (a cross-browser event handler present) Code: function initialize ( ) {
aArea=document.getElementsByName("area");
aStringRed=document.getElementsByName("stringRed");
for (var i=0; i < aArea.length; i++) {
addEvent (aArea[i], 'mouseover', changeColor);
addEvent (aArea[i], 'mouseout', changeOutColor);
}
}
function changeColor() {
????
}
function changeOutColor() {
????
}
Thank you in advanced for any help. Hi there, I have a menu with 4 links and 4 images associated with them. By default, the image from link 1 is displayed on the page. I would like to change the image with its corresponding one, each time i mouseover one of the other three links. I'm trying to make the following code work unsuccesfully, i might be missing something. Any help will be appreciated. In the <head> section i have this: <script type="text/javascript"> img1 = new Image(); img1.src = "images/party/party.jpg"; img2 = new Image(); img2.src = "images/party/icecream.jpg"; img3 = new Image(); img3.src = "images/party/juice.jpg"; img4 = new Image(); img4.src = "images/party/videogames.jpg"; function change(num){ document.images["linkpic"].src = "img" + num } </script> </head> In the <body> i have: That's my default image <table> <tr> <td width="100"> <img src="images/party/balloon1.jpg" name="linkpic"> </td> <td width="260" valign="top" align="left"> <table> <tr><td><a href="Party1.html" onmouseover="change('1')">Party and Fun</a></td></tr> <tr><td><a href="Party2.html" onmouseover="change('2')">Icecream </a></td></tr> <tr><td><a href="Party3.html" onmouseover="change('3')">Juice </a></td></tr> <tr><td><a href="Party4.html" onmouseover="change('4')">Video Games </a></td></tr> </table> </tr> </table> </body> I would like when i point to Icecream, the picture on the left to change to the Icecream picture and so on. Any hints and help are appreciated! Thanks! Hello. I have a script that detects the image size of a url and then shows a resized version of the image if it's necessary to resize. (this script was provided to me by the user bullant, thank you.) (Script will be shown later further down) In order to display the resized image, I must specify the id tag of myImg(and a number) in the img tag and must have an equal number of urls in the script as I do img tags. So, if I have three images I need to do the following to get them to appear. Code: <div><img id="myImg0" src='' alt="" /></div>
<div><img id="myImg1" src='' alt="" /></div>
<div><img id="myImg2" src='' alt="" /></div>
And this is the script (it can go right below the above code and all in the body tag): Code: <script type="text/javascript">
var picUrl = [
'http://localhost/test/pic1.jpg',
'http://localhost/test/pic2.jpg',
'http://localhost/test/pic3.jpg',
];
//create image objects
oPic = new Array();
for(i=0; i < picUrl.length; i++){
oPic[i] = new Image();
oPic[i].src = picUrl[i];
}
window.onload=function(){
var maxWidth = 200;
var maxHeight = 200;
for(i=0; i < oPic.length; i++){
var width = oPic[i].width; //original image width
var height = oPic[i].height; //original image height
//set the image size to display on the page
var newDims = calcNewDimensions(width, height, maxWidth, maxHeight);
document.getElementById('myImg'+i).width = newDims['width'];
document.getElementById('myImg'+i).height = newDims['height'];
document.getElementById('myImg'+i).src = oPic[i].src;
}
}
function calcNewDimensions(width, height, maxWidth, maxHeight){
newDims = new Array();
//scaling factors
var xRatio = maxWidth / width;
var yRatio = maxHeight / height;
//calculate the new width and height
if(width <= maxWidth && height <= maxHeight) { //image does not need resizing
newDims["width"] = width;
newDims["height"] = height;
} else if(xRatio * height < maxHeight) {
newDims["height"] = Math.round(xRatio * height);
newDims["width"] = maxWidth;
} else {
newDims["width"] = Math.round(yRatio * width);
newDims["height"] = maxHeight;
}
return newDims;
}
</script>
O.k. Now, I have the following I am working with: Code: <!--Image 5--> <img src="http://blahblah.com/images/red2.jpg" alt="Item photo" onmouseover="document.swap.src='http://blahblah.com/images/red2.jpg';" height="80"> in which you can see that onmouseover, a larger image is shown (it's not rescaled). You can also see that the url of an img is specified there. How can I get the rescaled image to show in that spot or the url from the picUrl Array and the image shown in the correct size, in that spot of Code: onmouseover="document.swap.src= ? This is the entire area in which the onmouseover code will be used in case you need it. Code: <html>

Since I like to minimize on graphics to keep bandwidth low, I have been using a script to simulate buttons. When you mouseover, you get some color changes which revert back when you move the mouse off. Simple, right? The problem is that firefox totally ignores the script. Even worse, safari changes on mouseover, but doesn't revert on mouseout. I have this in the heading: Code: <script LANGUAGE="JavaScript">
function ColorBlock(oRegion,sLinkID)
{
if (document.readyState != "complete") return;
window.event.cancelBubble = true;
oRegion.className = "MenuSelected";
oRegion.style.cursor="hand";
sLinkID.style.color = "black";
}
function UncolorBlock(oRegion,sLinkID)
{
if (document.readyState != "complete") return;
window.event.cancelBubble = true;
var oToEl = window.event.toElement;
if ((oToEl && !oRegion.contains(oToEl))||!oToEl)
{
sLinkID.style.color = "white";
oRegion.className = "MenuUnSelected";
}
}
</script>
And this is in the body. Code: <table class=MenuTable>
<tr><td OnMouseover="ColorBlock(this, Link4);"
OnMouseout="UncolorBlock(this, Link4);"
CLASS="MenuUnSelected" nowrap>
<a STYLE="color:white" ID="Link4"
OnMouseover="this.style.textDecorationNone=true;" href="javascript:createWindow('edu.htm','edu','toolbar=1,location=1,directories=1,status=1,menubar=1,scrollbars=1,resizable=1,width=825,height=725')">
<div style="width:144; cursor=hand; font-weight:bold;">
Education
</a></div></td>
</tr>

I have a bunch of these "buttons" ... firefox ignoring the code is annoying but safari only using half the code makes it look really bad. Anyone have any ideas? I've done a lot of work over time on the site, there are just a few bugs that have been avoiding me and I am trying to hunt them all down and kill them. The page is at www.adam-k-watts.com I'm no coder, as you will soon discover. The web work I do is from a purely novice, even hobby standpoint and the sites I create and host are nothing more than favors for friends and acquaintances who have needed but have not had a presence on the web. This being explained, I am asking those with coding skills to please take a look at the site I've just completed for a little diner down the road. (They're just starting out and can't afford to pay a professional web designer and, unfortunately, are stuck with me.) The site is http://d-n-ddiner.com I'm the first to say that the mouseover sound would drive me crazy, but the guys who own the diner are enthusiastic and want it left as is. I have had to combine scripts in order to have the "black-and-white to color" image effect work simultaneously with sound. The sound script depends on uploaded files: soundmanager.js, soundcontroller.swf and sound-config.xml and its tags are found incorporated with each involved image, within the body. The image effects are just the result of playing around with bits and pieces I've seen, mucking about the Internet. Its script is found within the head and also within the body, in each involved image's area, in mouseover, mouseout and, of course when specifying "name=" (such as Img_1). I opted for providing the sound in this manner because I am able to use an .mp3 file, rather than having to weigh through the pros and cons of .au versus .wav, etc., and the fickle nature of different browsers and plug-in crashes. After having many test the site (friends with varying operating systems and browsers) it appears that this mp3 solution makes the mouseover sound available to a broader range of users. Success has been achieved with Firefox, Safari, Netscape, Omniweb and Chrome. However, Internet Explorer and Opera seem to be the holdouts for both Mac and PC users. All this brings me to two requests: Would someone take a look at the site (particularly with Firefox) to determine if something might be done to help the page load more smoothly? Secondly, is there some sleight-of-hand that might be incorporated into the script to help IE and Opera detect the mouseover sound or do you consider these two browsers essentially not worth the bother? I am attaching a zip of the sound files I mentioned. The mp3 is not included but any mp3 snippet would do for testing, provided the sound config file is edited to reflect its file name. My primary concern is smooth page-loading; the IE and Opera issue is of less importance. Thank you for your patience and for any assistance you would offer. Hi all, I am using the following script posted on this site: http://www.javascriptkit.com/script/...oundlink.shtml It works great, but I want to extend this script and mute the sound using a checkbox. This checkbox has the id: sound. If checked, I want to hear the sounds, when unchecked, no sounds should be heard. This is the code I currently have for the checkbox: Code: function playSound() {
if (document.getElementById('sound').checked){
-something needs to be added here to make it work?-
}
}
Anyone have an idea how to make this work? Many thanks I set up an image mouseover for the next button but its not working. I have two images set up but the second one wont appear when mousing over image. You can see it at www.college-ebook.com I have created a page using the code below and it works fine. Is there any way that I can replicate the gallery further down the page using different images? When I try, the mouseover on the top gallery opens the images in the bottom gallery. Code: <script>
function changeimage(towhat,url){
if (document.images){
document.images.targetimage.src=towhat.src
gotolink=url
}
}
function sshow(){
window.location=gotolink
}
</script>
<script language="JavaScript1.1">
var myimages=new Array()
var gotolink="#"
function preloadimages(){
for (i=0;i<preloadimages.arguments.length;i++){
myimages[i]=new Image()
myimages[i].src=preloadimages.arguments[i]
}
}
preloadimages("i/1-big.jpg","i/2-big.jpg","i/3-big.jpg","i/4-big.jpg")
</script>
<script>
function changeimage(towhat,url){
if (document.images){

gotolink=url
}

}

http://www.outwarstop.com/woz/woz09r3a.php On this page located around where it says Drops under where it says "Sha-Zhul ArchDemon [60]" are the mouseover's but the location of the popup doesnt come up at the mouse, but on the left side of the table, i need help gettin the popup to appear where the mouse is located. I'm working at masking my fantasy football site hosted by my provider onto my own subdomain, since they can't allow me point a dns at their servers. I did manage to mask the webaddress to my sub doman with a php script. But it also only masks the initial visit, and th link name. And now i'm trying to learn how mask the various url/links in the menus. As I little about javascript, can someone show me a way to mask the url address when a user mouses over them? The links themselves wont' change, I'm just trying to mask the link names on the mouseover to look like their on my own domain. Hope that all made some sense Hi there. I'm trying to make a little valentines website 'card' for my ladyfriend. I was going to be clever about it and use javascript, but as it turns out I'm really not that clever with it anymore. I need a single image to change into a different image on each following mouseover event. A planned 'route' of images, for exameple A -> B -> C -> D -> E -> A -> F - > B -> .. and so on. I thought I could do this, but I'm getting nowhere. I did try to look for similar attempts to make this, but it's kind of hard to find since 'mouseover' is such a generic search term. Thanks. Edit: there's little point for me in posting my code so far.. it's just a long list of imagecodes and a little mousover script that would probably make you laugh. I tried to use the CSS Horizontal List Menu from http://www.javascriptkit.com/script/...stopmenu.shtml, and it is working with the one exception of the three images not showing up. I did did save them to the directory that contains the page I pasted the scripts to, and all of the links are showing in plan test only. I placed them original in a sub-folder call graphics which is the folder I have all of the graphics in. I also place them in the root director that has all of the HTML fiiles.
Hey guys, I need some help. I have divs placed in a html document, and what I need to do is have a sound play when a person is to hover their mouse over the,.

this is in a php page, thats the reason for the extra slashes/espaces. for some reason, only the last row of the menu works with the mouse over, maybe I'm missing something, but it seems like it should all work. any ideas would be really helpful. cheers, -Ken I would like to have an image color change when mousing over it, thus defining it as a link. What do I have to do to make this happen? Thanks.
The following piece of codes work like this: When mouse pointer is moved over the Button, the text of the button changes; When it is moved out of the button, the background color of the button changes. <html> <head> <script type="text/javascript"> function over(e) { if(e.toElement){ if(e.toElement.tagName.toLowerCase() == "input"){ e.toElement.value="IE New"; } } } function out(event) { if (event.srcElement){ if(event.srcElement.tagName.toLowerCase() == "input"){ event.srcElement.style.background= "green"; } } } </script> </head> <body> <div id="1">aaaaaaaaaaaaaaaaaa </div> <input type="button" value="Button 1" onmouseout="out(event)" onmouseover="over(event)" /> </body> </html> This sequence works fine, until the following case: First let's see the direction of the button: (left) <--------> BUTTON <--------> (right) Now, move the mouse over to the button, from the right side of the button, both the text and the background color of the button are changed. Obviously, the mousemoveout event is also triggered. I believe in this case, only the mousemoveover event should be triggered. What caused this? Thanks Scott Hi, I have a series of images, anchored linked together to simulate a tour. I decided it would be better if rather than clicking it was like a smooth simulation so i added onmousever to the anchor links. this was a smooth transistion but entirely too fast. is there a way with javascript, to slow down the onmouseover events? i have the images on the same page, just shoved down the page by using pagebreak html, so that they load when the page loads and therefore don't slow down the effect. (they are large images). i can't use the script that smoothly scrolls between anchor links, because it scrolls down the page to the next image, which ruins the effect. the images are increasingly larger pictures of the same thing, so the effect is somewhat like moving thru 3d space. i need the onmouseover to FIRE but move slower than normal onmouseover before firing again. repeat. here's an example http://www.thelivingmoon.com/undomie...rmouse.html#22 i mean the entire sequence is done before the person even realizes what just happened |
