JavaScript - Circular Image Map Onmouseover Flicker
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!!! Similar TutorialsHi 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. 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 ??? 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 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 -->
<img id="info" src="Images/info.png" border="0">
</div>
</body>
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 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;
}
//-->
</SCRIPT>
</head>
<body>
<a href="2_17_10/index.html" onmouseover="roll('poster','2_17_10/IMG_7075b.jpg')">2-17-10</a>
<img src="2_16_10/IMG_7072.jpg" name="poster" width=500></img>

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 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 Hi, Im working on a project for my website where I would like to be able to change the value of a number by using js, and using getElemenById. For example: "The taxi fare is $25" "A hamburger is $4" In the above sentence I would like to be able to change the value of 25 & 4 by giving them an id and then using js to increase (or decrease) their value, to allow for future inflation, without having to go back and manually change every number on lots of pages (if for example in 1 years time a hamburger is worth $6 then the info above is outdated and should be changed). If i could use a variable such as "RateUSD = 1" I could increase "1" to say "1.05" and it would increase the value of all id='USD' by 5% onload rather than having to manually change it by typing. I so far have come up with the code below, but I think the reason it does not work is because I have created a circular equation - id='USD" is the start of the equation, but it is also in the equation itself, and it is the resulting answer, so effectively I have created "A = A*B", or in this case "25 = 25*1.1" Would appreciate if anybody has had some experince with this type of js and could point me in the right direction. I chose "id" as I would like to be able to have different currencies (with different id, such as 'EURO','GBP', etc) on the same pages and on multiple pages. I'll crack it eventually, I would just like to know if I'm heading in the right direction, or is there a better method that I could use? I found plenty of example for changing text with "innerHTML", but so far I haven't seen any for updating numbers onload by calculation, except for forms, etc, which are different. The code: Code: <html>
<head>
<script type="text/javascript">
function changeCurrency(){
var RateUSD = 1.1
var USD = document.getElementById('USD').value =""
var A = RateUSD
var B = USD
var C = ((RateUSD) * (USD))
document.getElementById('USD').innerHTML = C
}
</script>
</head>
<body onload="changeCurrency()">
<p>The Taxi fare is USD$ <b id='USD'>25</b></p>
<p>A hamburger is USD$ <b id= 'USD'>4</b></p>
</body>
</html>
I will later put the js in an external file with a link to it "...src="support-files/currencyChange.js" (or something like that), but for now I have put it on the same page. Thanks and regards, Terry 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, I have a scenario in which i have to drag and drop some objects in a circular motion, but under spacific boundaries. To expain the scenario better, I have attached a image of the problem. If possible kindly provide me code, either logical description/solution of the problem would be very helpful. Thanks Sa9chit 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>
hi, please ignore this thread..it is a duplicate of one already active. MODS please delete. apologies for my mistake. I have seen many reports of this problem online but none of the fixes appear to exactly solve my problem. I need to be able to solve this problem with minimal code changes (code generated by a graphic designer in Dreamweaver). A section of the relevant code is below. The menu items are all images in AP DIVs. The menu items all flicker in IE and the onClick doesn't seem to have time to process. This works fine in FireFox. I've tried setTimeout around the call to MM_showHideLayers but this didn't seem to work. Any suggestions please? Code: function MM_showHideLayers() { //v9.0
var i,p,v,obj,args=MM_showHideLayers.arguments;
for (i=0; i<(args.length-2); i+=3)
with (document) if (getElementById && ((obj=getElementById(args[i]))!=null)) { v=args[i+2];
if (obj.style) { obj=obj.style; v=(v=='show')?'visible':(v=='hide')?'hidden':v; }
obj.visibility=v;
}
}
function MM_goToURL() { //v3.0
var i, args=MM_goToURL.arguments; document.MM_returnValue = false;
for (i=0; i<(args.length-1); i+=2) eval(args[i]+".location='"+args[i+1]+"'");
}
.
.
.
<div id="hello" onmouseover="MM_showHideLayers('helloover','','show')" onmouseout="MM_showHideLayers('helloover','','hide')" ></div>
.
.
.
<div id="helloover" onclick="MM_goToURL('parent','index.html');return document.MM_returnValue"></div>
Alright I know about the problems IE has, but I'm testing out an id that is titled "slideRecord1" and trying to move it. The functions work with Firefox for the onmouseover and onmouseout attributes. But IE doesn't support that. So I'm trying to do it manually in the Javascript, but it's still not reading it. Any help? Code: /* <![CDATA[ */
document.getElementById('slideRecord1').onmouseover = function(){slideRecord(1);}
function slideRecord(disc)
{
var record = "disc"+disc;
var y = 20;
document.getElementById(record).style.top = y + 'px';
}
function unSlideRecord(disc)
{
record = "disc"+disc;
var y = 0;
document.getElementById(record).style.top = y + 'px';
}
/* ]]> */
I have been googling this for two days and am coming to the conclusion that the answer is no. Am I correct?
Hi Guys im new to javascript but i have got this code so far to work Code: <script type="text/javascript">
