JavaScript - Switch Image On Mouse Events... How To Increment
Example of my problem:
HERE The code is derived from a site offering some advice for javascript: HERE The example of mine tries to use an image as hyperlink... and use mouse events for certain actions. Aside from possibly being the worst javascript code humanly possible...once I slaughtered the code from the site mentioned above, I'm not getting how to arrange things so that a mouse over event switches an image , as does mousedn and mouseup, And (and this is the rub for me) repeating the setup in the same way for a list of quicktime video links. I've got it to work for one row in the table I'm using to attempt some kind of formatting. I'm told `css' is a better way for that but I'm completely ignorant about how to use `css'. So, for now I'm using a table to get at the javascript question. The idea is for viewer to see three red dots at the front of each item being offered. Mouseover is supposed to switch to a green arrow... mousedn is supposed to switch to 2 check marks. I wanted the check marks to persist, so for lack of knowing how to accomplish that... I let mouseup call the same image. (the check marks; Maybe just omitting any directive for mouseup would have the same effect?) About the `image persisting after being clicked' question: It is really a separate question so I will probably start a different thread for that. What I've done works for one list item... but fails for more than one. The only active member of the list (2 in my example) is the bottom one. mouse events on the top one are carried out on the bottom one. I tried to just change the name of all variables in the javascript, and the name given in the `img src=' section of the html code, for the second row... but clearly not what is needed. I changed the names shown below by incrementing the number in the names by 1. I've only posted one row's worth but the next row uses the same code with the variables incremented. And hopefully someone will look at the actual example (URL given above) and see the full code. The basic code I've put here for convience.: Code: <table>
<tr>
<td valign=top >
<A href="./t2.html" onMouseOver="return changeImage()" onMouseOut= "return changeImageBack()"
onMouseDown="return handleMDown()" onMouseUp="return handleMUp()"
><img
name="jsbutton_0" src="./3dots.png" border="0"
alt="javascript button"></A> some nice video
<SCRIPT language="JavaScript">
var myimgobj_0 = document.images["jsbutton_0"];
function changeImage()
{
document.images["jsbutton_0"].src= "./aro1r-mo.png";
return true;
}
function changeImageBack()
{
document.images["jsbutton_0"].src = "./3dots.png";
return true;
}
function handleMDown()
{
document.images["jsbutton_0"].src = "./checks.png";
return true;
}
function handleMUp()
{
document.images["jsbutton_0"].src = "./checks.png";
return true;
}
</SCRIPT>

Similar TutorialsHi I have a requirement....I have a timer on a page. If the user leave the page (mouse goes off of that page) the timer starts and continues...and when the user comes into that page(mouse over that page) the timer goes off/STOP....Is this can be done?? using javascript??? pls help... Is it possible to trigger mouse events with shapes drawn in an HTML5 canvas? I want to create a page with drawn elements that you can mouseover and pop up a dialogue box. I also want the shapes to react with some type of feedback. I'm hoping I can do this with javascript instead of Flash but haven't found a way to do it that's simple enough to make it worth it.
Hi! Just registered, because I'm trying to figure out some dragging stuff and it's not working the way I'd like and I really can't figure out why. I made a drag element (image). I just want to apply the code to this element. This is what happens: 1. I click on the image 2. I hold the mouse down and drag => the element don't follow 3. I let go of the mouse button => the element gets dragged 4. I click again => the element stops dragging This is what I would like to happen (obviously): 1. I click the image 2. Hold the mouse down and drag => element follows 3. Mouse up => element stops following Code: var dragSko;
var dragSkoUrsp;
document.onmousedown = startaKod;
document.onmouseup = musUpp;
function startaKod(e) {
if (e.target.id == 'dragsko') {
startX = e.clientX;
dragSkoUrsp = parseInt(e.target.style.left);
document.onmousemove = musFlyttDrag;
dragSko = e.target
}
function musFlyttDrag(e) {
dragsko.style.left = (dragSkoUrsp + e.clientX - startX) + 'px' ;
}
}
function musUpp(e) {
document.onmousemove = null;
}
I'd very much appriciate if some kind soul had a look and explained what I've done wrong. I'm trying to enable/disable a textarea. I am able to do a mouseout disable, but cannot do a mouseover enable. For instance, when I click on the image, a textarea shows up. When I move my mouse to a different location, the textarea disables fine. Then when I try to move my mouse back over the textarea, it DOES NOT enable for me to write in it. What am I doing wrong? Thanks! Another bonus question, I just happen to try out this code in IE and the textareas are not showing up where I click. I assume that I'm capturing the X/Y coordinates incorrectly for an IE browser.

All the coordinates are set right before firing the event. But when the event gets fired, the client point gets changed and gets the value same as offset point. i.e., I created a mouse event with ClientPoint = (583,438) , offset= (585,481) and screen = (585,589). The event when it gets fired from the browser however has the client point as (585,481) - the rest are fine though. Can someone tell me how can I reliably fire a mouse event at a particular client point in IE? TIA srd I've got to have a typo somewhere, but i can't seem to find it. I need a new pair of eyes to point it out for me. background: trying to code a mouseover link for a nav bar. everything is working( hyperlink, normal image shows up) but when i mouse over the image swap doesn't happen. I have 2 parts of code. 1st preloads images and does the swap function. loads in <head> See below: Code: <SCRIPT language="javascript" type="text/javascript">
if (document.images)
{
/* preload images */
var subcontractorsOn = new Image ();
subcontractorsOn.scr = "subcontractorsOn.gif";
var subcontractorsOff = new Image ();
subcontractorsOff.scr = "subcontractorsOff.gif";
}
function mouseOn (imgName)
{
if (document.images)
document [imgName].scr = eval (imgName + "On.scr");
}
function mouseOff (imgName)
{
if (document.images)
document [imgName].scr = eval (imgName + "Off.scr");
}
</SCRIPT>
2nd just calls the functions to preform the swap. this is in the <body> see code below Code:
<a href="subcontractors.htm" onMouseOut="mouseOn('subcontractors')"
onMouseOver="mouseOff('subcontractors')">
<img src="subcontractorsOff.gif" height="40" width="133" name="subcontractors" id="subcontractors" border="0" alt="subcontractors"></a>
any insight would be great. regards, Fatmann66 Hi, I am still designing the website and want some flexibility. I am capturing the mouse clicks fine on top of an image, but the coordinates are absolute and not relative to the image. How can I capture mouse clicks relative to the image so that I can move the image anywhere in my website? Thanks! I am using a freebie script that changes css elements using onClick when you hit a button. I have 12 choices I want to add, and don't want 12 buttons, but rather a dropdown list. 2 button examples (and js code) is: <input onclick="changecss('li','background','url(images/list_02.jpg) no-repeat 10.2em .12em')" value="Change to BG 2" type="button" /> <input onclick="changecss('li','background','url(images/list_03.jpg) no-repeat 10.2em .12em')" value="Change to BG 3" type="button" /> How do I convert this to a SELECT list?? Thank you! How to mouse over the image then the words will appear below it?
Hello, I'm new to this forum and well... I'm pretty new to JavaScript as well. Here's my problem: I'm trying to create a switch image code that will allow the new image to be a link as well. In the list item where you'll see ('blue.jpg') if I try to make this an anchor tag - it breaks the code. Any suggestions would be great. Thanks for taking a look! Code: <head>
<script>
function switch1(div) {
if (document.getElementById('blue')) {
var option=['blue','green','purple'];
for(var i=0; i<option.length; i++)
{ obj=document.getElementById(option[i]);
obj.style.display=(option[i]==div)? "block" : "none"; }
}
}
//
function switchImg(i){
document.images["blue"].src = i;
}
</script>
<style>
#image-switch ul {
margin:0 0 0 20px;
color:red;
list-style-type:none;
}
#image-switch li {

I know theres a lot of codes out there online for this but I cannot seem to get any of them to work for me. I am trying to make my layout for an item page for an online store. I'd like one big image, with one or 2 thumbnails under it which when clicked will switch the big image. Clicked, not mouseover. Lets say my big images would be REG1.jpg and REG2.jpg, the first being the image on the page that will switch. THUMB1.jpg and THUMB2.jpg being the thumbnails. Is there a simple way to do this or is the code a complete mess like I've been seeing on so many pages? I'd say I have an intermediate understanding of HTML and I've just started teaching myself javascript but I'm starting to fall off the wagon, I can't decipher the stuff coming up in these example codes. Any help would be thoroughly appreciated!! Hello everyone, I'm looking for a javascript script that will load a small image where the mouse is, then it would go away after a couple seconds. Thanks a bunch! I Need some help with mouse overs. I have 2 images, Image A and Image B. I need to mouse over Image A and have Image B change. Please help.
My goal is to have one big picture center with 4 smaller pictures to the left that you click on and is target to the center. When you click on the center it will zoom. I haven't worked on it in a few years and not able to find the person who wrote the code. I added the zoom coding to the picture switch. The zoom works fine but when you click the smaller images the image is not viewable. Coding in the head Code: <!--Image Viewer-->
<script language="javascript" type="text/javascript">
<!--
function canManipulateImages() {
if (document.images)
return true;
else
return false;
}
// loadPosterImage
function loadPosterImage(imageURL) {

return false;
}
else {
return true;
}
}
gImageCapableBrowser = canManipulateImages();
// -->

If someone could help me out by adding the code so the images switch would be great! area of an image on which the mouse is positioned should only show in the preview, not the full image .. is this posible if yes how ?? Plz suggest me something ........... Samaiya Hi, I am new here, I am trying to find solution for one problem with my new web page, I want to use amazing effect -by mouse draging or swipe on the certain image which should launch animation effect (something like image rotating) -set of images should run dynamicaly and so simulate fluid effect (movie). For a better Idea what I need it can be for example something as physical lever switch with spring when this switch is slightly tilted spring complete this action and switch is flipped to other state. Or another example image of book should be on web and when someone drag and pull page this should independently continue and complete action - turn to new page. So my question .. is something like that possible with javascript if yes can You please point me where I have look or how this can be done, each advice will be valuable for me or maybe javascript isnt right choice for this can You advise me? THANKS Hi all, First post here in a long time, I'm finally getting round to sorting out a portfolio website. I have a rollover image which has a mouse over and down action and a table cell which has a mouse over and down action which swaps the assigned css class. What i need to happen is when i mouse over the table cell containing the rollover image the table cell below switches the style assigned to it. I have it working the other way around so when you mouse over the bottom cell the image in the top cell swaps, see he http://onebitrocket.co.uk/swapimageandtext.html I'm basically looking for an action similar to a swap image in a cell which has it's ID defined onmouseover="MM_swapImage('Image4','','images/thumbs/th04.jpg',1)" so onmouseover="MM_swapstyle... Any help would be great Thanks hi everyone, firstly to call myself a noob would be inflating my ego. I have done one project in javascript so far and have had no schooling on the topic, however I have learned quite a lot in the last few months from this thing called the 'internet'. So far I managed to make an html image map that has various tooltips which will appear onmouseover, and the tooltip disappears onmouseout. Each point of coords that i have defined has a hyperlink to a different page on the internet. It works just like i wanted it to and i couldn't be happier, that is, when i'm using a mouse... When i am using a touchscreen device it is a different story. specifically i'm trying to port my html page to android as i figured it would be easy with the android sdk and webview (it was, but read on). What i found when i used the 'app' on my phone was that onmouseover works when you touch the screen, however it also registers as a click, so pop goes the tooltip, and i'm whisked away to my webpage. not the desired result. Ideally I would like to hold down the screen for 3 seconds and then the hyperlink would activate, but i decided that just getting the thing functional would suffice for the time beaing so i tried to include some 'ondblclick' that would trigger a document.location. This worked fine on a web browser again, but had no result on the touchscreen. I decided to abandon this half step because I have read that ondblclick doesn't work in an image map and it isn't my intended result anyway. I have found a lot of javascript and jquery samples that emulate the onHold event that i'm trying to achieve, both on this forum and all over the internet, however these samples are overly complex and are focused on looping an action, such as incrementally increasing a value or zooming or whatever. I just want to redirect the user to another page if they trigger 'onmousedown' for 3 seconds. anybody want to trade some help for a thankyou? want to get selected text and image values .Since there is an randomly changed text and image on my page.I used window.getSelection() but this will return only selected text values not images ..so please guide me to solve this problem.
