JavaScript - Onmouseover Image Rollovers
HI,
I am not very experienced with javascript and got stuck doing the following. I have placed some image rollovers on one of my pages..where when a user rolls over some text links..and image appropriate to that text is showen...when the mouse moves away from the links then a blank image is displayed as a place holder. this is all simple...here is where i am stuck. The place holder has a specific size...but the rest of the images that are displayed when the text is rolled over have different sizes, some are vertical some are hortizontal. i do not want to have to resize every image so that it properly fits the place holder...add the white borders and so on...so that the image is dispalyed properly. Is there a way to have the size be changed for each image...so that the size doesnt get inherited from the place holder, but so that the script applies the size associated with each individual image. example place holder is 20 x 20 image 1 is 100 x 200 image 2 is 200 x 100 the place holder is loaded...when the mouse moves over the first link...image 1 replaces the place holder...but instead of taking on the size of 20x20 it has to be displayed at its own size of 100 x 200... how can i do this? thank you for all of your help Similar TutorialsSay we have an image called imagefile.jpg, which we want to display when the user mouses over an already-displayed image.Now I want to preload more than just one image; for example, in a menu bar containing multiple image rollovers,or if I try to create a smooth animation effect what should i do? I tried the following code but it doesn't work. Please help Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Mainly I want to create the animation effect with the 4 images. Is that possible? First off, I am new here - so, an introduction. My name is David Lubofsky. I am a front-end developer in Chicago, Illinois. I have done numerous JS rollovers before, as well as image rollovers triggered by text links. However, I am having a problem combining the two. The best example I have found of what I am trying to achieve is here - http://theworldcovered.ivyfunds.com (top right area). I have no issue achieving part of this - where the link mouseovers trigger the image swap. My issue is making both the link and the image cause the rollover. The method I use for image swap on text link hover is seen here - http://www.htmlite.com/faq011.php This is what I want, except I want the image to also swap if the image is rolled over, as in the first example. Hope this was clear - I could really use some guidance on this. Thanks all! David Hi there, New to these forums, and to coding websites so be kind . My problem is, when using lightbox2 I press the back button and the rollover remains in the mouse-over position. I can "mouse over' it and then the rollover will disappear, it just seems to get stuck on. I really have no idea what is causing this, and any help would be greatly appreciated. Thanks alot, Joel Hi guys, Just wanted to know (seeming im a bit of a jscript beginner). it is possible to have a background image rollover, and if so how. Thanks. i am trying to use the most simple code i can to onmouseover of some text change 1 image. it will have multiple texts with different images for each one all displayed in one place. it seems to work well for me in IE, but on firefox the mouseover doesn't work. and on a mac it doesn't work in safari or firefox. any input is appreciated... here is the shortest version of the code i could put together. Code: <head>
<SCRIPT LANGUAGE="JAVASCRIPT">
<!--
function roll(img_name1, img_src1)
{
document[img_name1].src = img_src1;

Hi everyone. Can anyone help me , i need to make a onmouseover function , when u go with mouse on the left small image it automatically opens the large image in the right, can anyone help me with this ??? this is my script Quote: <a href="javascript:void(0);" onmouseOver="hahaha()"> <img border="0" src="pink.gif" name="Mainpic" id="image"></a> and this is the function Quote: function hahaha() { document.getElementById('image').src="blue.gif"; } the problem is when i mouseover the image look like this why is that? help please! thanks I have six small images. Depending on which image a user hovers over, I would like a seventh image (a simple box) to change as well. For example, if a user hovers over image1, I want the seventh image to be a red box. If a user hovers over image2, the seventh image should be a blue box. Simple huh? So the seventh image changes color based on which of the six smaller images the user hovers over. ------------- So far, my current code only allows me to hover over any of the six images, and the seventh image always changes to the same image color. Code is below. Any help would be appreciated. Code:
<script type="text/javascript">
function hoverBox() {
var boxNumber;
document.getElementById("info").src = "Images/infoRedColor.png";
}
function hoverBoxOut() {
document.getElementById('info').src = "Images/info.png;"
}
</script>
</head>
<body>
<div id="wrapper">
<a href=""> <img class="box1" src="Images/box1.png" border="0" onmouseover="this.src='Images/box1hov.png'; hoverBox()"
onmouseout="this.src='Images/box1.png'; hoverBoxOut()" ></a>
<a href=""> <img class="box2" src="Images/box2.png" border="0" onmouseover="this.src='Images/box1hov.png'; hoverBox()"
onmouseout="this.src='Images/box2.png'; hoverBoxOut()"></a>
<a href=""> <img class="box3" src="Images/box3.png" border="0" onmouseover="this.src='Images/box1hov.png'; hoverBox()"
onmouseout="this.src='Images/box3.png'; hoverBoxOut()"></a>
<a href=""> <img class="box4" src="Images/box4.png" border="0" onmouseover="this.src='Images/box1hov.png'; hoverBox()"
onmouseout="this.src='Images/box4.png'; hoverBoxOut()"></a>
<a href=""> <img class="box5" src="Images/box5.png" border="0" onmouseover="this.src='Images/box1hov.png'; hoverBox()"
onmouseout="this.src='Images/box5.png'; hoverBoxOut()"></a>
<a href=""> <img class="box6" src="Images/box6.png" border="0" onmouseover="this.src='Images/box1hov.png'; hoverBox()"
onmouseout="this.src='Images/box6.png'; hoverBoxOut()"></a>
<!-- Seventh Image -->

Hi Guys. First off i'd like to say Hi as i'm new to the forums. But am looking forward to spending a lot of time here. I am currently studying Javascript to help create a bit more user interaction with my websites which I use CSS/XHTML and PHP5 to design. Ok with that said I was hoping someone might be able to lend a slight hand. I am trying to create an Image menu for a site I'm working on that is rather simple in essence. When the user hovers over a button I have the menu will move left or right depending. I have not got a great deal into it yet as I have become stuck, as I'm new I figured it would be easier to troubleshoot if I build up the program bit by bit. ----> menupic variable is being passed by php into javascript Code: function moveImagesLeft() {
for (i=0; i<=100; i++) {
setPixels = (i + 2);
for (L=1; L<=menuPic; L++){ /* this loop makes sure that all the pictures move together */
indexpic = "menupic"+L;
document.getElementById(indexpic).style.left="-"+setPixels+"px";
}
}
}
Ok, very simple. I have a DIV container that holds my images and the overflow is hidden, php works out how many images there are and feeds that into javascript. This all works fantastically however it seems that once I reach the bottom of my second for loop Code: document.getElementById(indexpic).style.left="-"+setPixels+"px"; Nothing else happens, the pictures all shift left 2pixels as they should but nothing else. The top loop is not going again (excuse the poor use of terminology) I dont know if it makes a different but where the images are they are declared as so. Code: <a href="#"><img class="menupic" id="menupic1,2,3,4,5 (etc)" src="_image" border="0" height="50" width="60"></a> Code: .menupic {position:relative; display:block; width:60px, height:40px}
and the Id class is there so that my javascript can control it. I hope that I have worded this in a way that is easily understandable. Any help would be greatly appreciated. I try not to ask for too much help because working things out is part of the learning curve but in this instance I have spent a lot of time and not found a solution. Kindest Regards Oli Is it possible to atchually make a javascript that onMouseOver an image expands a seperate image and also works multiple times? say from 1 px wide to 25px wide? It would be a great help if someone could help me with this one. I have an image map with 6 areas. Code: <p class="center"><img src="images/car_feature.png" alt="" usemap="#car"/></p> <map id="car" name="car"> <area shape="rect" coords="172,198,195,222" href="#" alt=""/> <area shape="rect" coords="242,79,266,104" href="#" alt=""/> <area shape="rect" coords="293,124,317,149" href="#" alt=""/> <area shape="rect" coords="407,212,431,227" href="#" alt=""/> <area shape="rect" coords="430,300,453,325" href="#" alt=""/> <area shape="rect" coords="565,346,588,370" href="#" alt=""/> </map> I also have 6 DIVs that are hidden and only a single one will appear visible on mouseover of its corresponding image map area. Code: <div id="hidden"> <div class="feature"> Feature 1 </div> <div class="feature"> Feature 2 </div> <div class="feature"> Feature 3 </div> <div class="feature"> Feature 4 </div> <div class="feature"> Feature 5 </div> <div class="feature"> Feature 6 </div> </div> The roadblock I'm running into is the show function in the JavaScript. Code: window.onload = init;
function init() {
var area = document.getElementById("car").getElementsByTagName("area");
var features = document.getElementById("hidden").getElementsByTagName("div");
hide();
function show() {
for(a=0; a < area.length; a++) {
if(area[a].onmouseover) {
document.getElementById("hidden").getElementsByTagName("div")[a].style.display="block";
}
}
}
function hide() {
for(b=0; b < features.length; b++) {
document.getElementById("hidden").getElementsByTagName("div")[b].style.display="none";
}
}
for(i=0; i < area.length; i++) {
area[i].onmouseover = show;
area[i].onmouseout = hide;
}
}
I'm trying to get it so that if I hover over the first area on the image map, the first hidden DIV will appear, but none of the others. And if I hover over the fourth area, the fourth DIV will appear. I hope this makes sense, and I'd appreciate any and all help towards solving this issue and ending my headache lol So I need to make a circular image map with a rollover state. I have circular buttons that I'm trying to put on my website, which I would like to not only look circular bu to BE circular. Because it just looks lame to hover over a square area and activate a button that's still 30 pixels away. I was digging through the Internets and found this: http://jsfiddle.net/7JJUk/ My idea was to tweak the rollover overlay into being as large as my original image and use the rollover image as the content of the overlay div. After loads of messing around, I finally have come to this: http://jsfiddle.net/7JJUk/248/ I just know i'm on to something, but I don't know anything, really, about Javascript. I've been messing with the tidbits to figure out what controls what, but the issue I can't get past is how the image will flicker like mad (every other pixel in Chrome, sporadically in Firefox 4 whether you move the mouse or not, and only as you pass through it at certain speeds in IE 9) as you hover over it. I have no idea if this is even possible, but if it is, please help me out. If there's a better way to be doing this altogether (without flash), I would absolutely love that. Especially if there's a way to use an image map with the position command in CSS.. Thanks!!! Hello all, I'm new to this forum so please forgive me if I make mistakes and feel free to point them out. I'm a beginner when it comes to javascript, but would like to learn. I have been building a website that I would like to put an interactive feature on. This is the code that I currently have: Code: <a href="javascript:void(0)" onclick="changeImg(white, 'images/Bouquet_pink.jpg')" onmouseover="scroll_up();"><img class="pinkico" hspace="3" onMouseover="this.style.opacity=1;this.filters.alpha.opacity=100;" onMouseout="this.style.opacity=0.5;this.filters.alpha.opacity=50;" src="images/Bouquet_pink_icon.jpg"> <a href="javascript:void(0)" onclick="changeImg(white, 'images/Bouquet_yellow.jpg')"><img class="yellowico" hspace="4" onMouseOver="this.style.opacity=1;this.filters.alpha.opacity=100;" onMouseout="this.style.opacity=0.5;this.filters.alpha.opacity=50;" src="images/Bouquet_yellow_icon.jpg"> <a href="javascript:void(0)" onclick="changeImg(white, 'images/Bouquet_white.jpg')"><img class="whiteico" onMouseover="this.style.opacity=1;this.filters.alpha.opacity=100;" onMouseout="this.style.opacity=0.5;this.filters.alpha.opacity=50;" src="images/Bouquet_white_icon.jpg" ></a> I would like to have these images scroll together at the same time in accordance with the mouse movement. So when the mouse is just hovering over one of these images or elsewhere on my page they will stay still, but when the mouse is hovered over the left or the right hand side the images move in that direction? So if the mouse is hovering over to the left side the images will start to slide left and if the mouse is hovering over the right side the images will start to slide right. I have tried to do some research on this for myself but have only been able to locate this web page to explain what I am looking for: Link 1 - The type of effect I'm looking for is demonstrated by their first example, underneath the horizontal scrolling demo header. I have no idea how to achieve this code though and have failed to find any answers that I understand on the website. Adding two little arrow images for the mouseover and mouseout effect to happen would not be a problem, but I do not understand how to go about this. Hope this is ok, Thank you for reading , Nightshade14 Hi guys, I need some help. Im trying to make a navagation menu with images that need to be changed when someone hovers over the child category. So lets say I have a menu that looks like this: Code: <img src="notactiveimagemenu1.jpg" alt=""> <ul id="menu1"> <li>link</li> <li>link</li> <li>link</li> </ul> <img src="notactiveimagemenu2.jpg" alt=""> <ul id="menu2"> <li>link</li> <li>link</li> <li>link</li> </ul> Now what im trying to do is if someone hovers over the li items from menu1 to change the image src of menu1.jpg to active. I was hoping to do this with some javascript. Code: // i was thinking about something like this: // first put menu items in a array // then use document.getElementById(id).onmouseover = function() // and make some sort of check to see which src should be changed. Now I really have no clue how to do it. So if anyone knows a cool solution please let me know. I know I could add onmouseover events to each li item and changing the src of the category. But Im trying to find a better solution. And I think I should be able to use document.getElementById(id).onmouseover = function() for that. Anyway thanks for any tips. Please note I know I could use jquery to do all of this very easy but I consider this practice because I don't know that much javascript. hi, please ignore this thread..it is a duplicate of one already active. MODS please delete. apologies for my mistake. Hi, Im a complete newbie to javascript and I've basically copied and pasted the javascript I found here to use on my site. Its an onMouseOver slideshow: http://www.javascriptkit.com/script/...ifferent.shtml to use on my site. Basically, my problem is how do I add a second, separate image in a different location on the web page, associated with this script? If I post <a href="javascript:warp()"><img src="myimage" name="targetimage" border=0></a> in two different locations, which is the script for the image, the script stops working, but having it once makes it work. So how do I add two different image locations? Can someone please help me here? I just want to add more images in a different location. ie have image location 1, and image location 2. Thanks in advance Script Below: Code: <script>
function changeimage(towhat,url){
if (document.images){
document.images.targetimage.src=towhat.src
gotolink=url
}
}
function warp(){
window.location=gotolink1
}
</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(my images here)
</script>
For the Links:
<a href="creativewriting.html" onMouseover="changeimage(myimages[1],this.href)">Creative Writing</a><br>
For the Image:
<a href="javascript:warp()"><img src="myimage" name="targetimage" border=0></a>
I have the following 3 buttons on my page. I need when on hover on each respective button, the button to light up with a bg image and a slide out rollover in the top direction. How can I achieve this? <div style="padding-left:45px;width:852px;"> <a href=".html" class="Button"> <div style="text-align:center;padding-top:15px;float:left;width:270px;height:45px;background-image:url(images/homeBG.png);background-repeat:no-repeat"> <span id="homeButtonText">Question 1</span><br /> </div> </a> <a href="" class="Button"> <div style="margin-left:18px;text-align:center;padding-top:15px;float:left;width:270px;height:45px;background-image:url(images/homeBG.png);background-repeat:no-repeat"> <span id="homeButtonText">Question 2</span><br /> </div> </a> <a href="" class="Button"> <div style="text-align:center;padding-top:15px;float:right;width:270px;height:45px;background-image:url(images/homeBG.png);margin-right:5px;background-repeat:no-repeat"> <span id="homeButtonText">Question 3</span><br /> </div> </a> </div> Hi everyone, this is my first post on this forum and is also my first attempt to use javascript. When it comes to javascript I am a complete noob, but before you push the back button I just thought I'd let you know I just spent a few hours in some javascript tuts so I could *at least* have some idea of what you and I are talking about. Ok, here's my question: How can I make a disjointed div become and remain visible when I hover over it's parent div? The Only time I want that div to go back to being invisible is when I hover over another parent div causing it's child div to become visible. Here's the example (only tested in FF 3.5.2) : http://www.e-uphoria.com/demo_two.html I used :hover in css to show the disjointed div (the red box) that I want to become visible via javascript. I managed to achieve this effect with css, but when the user moves the mouse out of the browser window the div disappears because the hover is no longer activated. This is why I need javascript, so the user can do anything he or she wants outside of the browser window and the "hover" will still be activated revealing the content of the div. Here's the example of the css only version (again, only tested in FF 3.5.2) : http://www.e-uphoria.com/demo.html I messed around with some onmouseover and onmouseoff within the html and realized I could achieve the desired effect with some really messy and inefficient code. I would prefer to have the javascript in an external file and not looking like it was written by an idiot. If anybody could help me out with this that would be awesomely awesome. Thanks! Using Dreamweaver CS3 (WinXP), is there a simple way to add captions to disjointed rollovers? (The disjointed rollovers are created using image swap behavior) My aim is to click on a thumbnail, and when the image is projected on the poster, I want a caption appearing underneath. Can you please help me with this, here is my complete code Thanks [code] <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> <script type="text/javascript"> <!-- function MM_preloadImages() { //v3.0 var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array(); var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++) if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}} } function MM_swapImgRestore() { //v3.0 var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc; } function MM_findObj(n, d) { //v4.01 var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) { d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);} if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n]; for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document); if(!x && d.getElementById) x=d.getElementById(n); return x; } function MM_swapImage() { //v3.0 var i,j=0,x,a=MM_swapImage.arguments; document.MM_sr=new Array; for(i=0;i<(a.length-2);i+=3) if ((x=MM_findObj(a[i]))!=null){document.MM_sr[j++]=x; if(!x.oSrc) x.oSrc=x.src; x.src=a[i+2];} } //--> </script> </head> <body onload="MM_preloadImages('images/fullscreen/1z.jpg','images/fullscreen/2z.jpg')"> <p><img src="images/fullscreen/1z.jpg" alt="HL" name="pic1" width="114" height="102" id="pic1" onmouseover="MM_swapImage('poster','','images/fullscreen/1z.jpg',1)" onmouseout="MM_swapImgRestore()" /> <img src="images/fullscreen/2z.jpg" alt="HL" name="pic2" width="114" height="102" id="pic2" onmouseover="MM_swapImage('poster','','images/fullscreen/2z.jpg',1)" onmouseout="MM_swapImgRestore()" /></p> <p> </p> <p><img src="images/fullscreen/3z.jpg" alt="HL" name="poster" width="500" height="375" id="poster" /></p> </body> </html> [code] Good day Lets say I have a page with 3 thumbnails and one big div. When click in one of the thumbnails the image of it must appear inside the big div. Of course there are 3 images (little ones for the thumbnails) and 3 big images for the real size ones. Script this is simple for me but imposible if I have more than 100 pages within 6 images inside them (3 little and 3 real size for 3 thumnail divs and one single big div). There must be some kind of order to just script the divs of the thumbnail divs and the real size image div in all the pages at ones, otherwise I have to creat ID's to every single div inside every single page! (4 id's to one page and I have more than 100 pages!, this is inpractical because is posible that in the future the pics change, is more than 400 id's) For example: for FIRST.html big div (div id="img001bg") thumb1 div (div id="th_img001" thumb2 div (div id="th_img002" thumb3 div (div id="th_img003" SECOND.html THIRD.html ... HUNDRED.html ... ! There must be some solution using somehow the functions, please help! Thank you to all |
