Changing Onmouseover Dymnamically
Jan 9, 2006
I'm trying to change the onmouseover event dynamically.
This sets-up the initial onmouseover event:
<a href="home.html"> <img border="0" id="img22"
src="images/home1.jpg" height="15" width="85" alt="Home"
Here I'm changing the image and trying to disable the onmouseover
event:
<script type="text/javascript">
if (bHome==0) {
FP_swapImg(1,0,/*id*/'img22',/*url*/'images/contact1.jpg');
document.write ('<div id="img22"
}
</script>
This script works with Mozilla but not with IE.
Any recommendations or suggestions?

So I didn't think this would be very hard, but I keep running into problems.
I have:
function changeCSS(idName, newClass) {
document.getElementById(idName).className=newClass;
}
And then:
<p id="Link1" onmouseover="changeCSS(Link1, '#profileNav .hoverNav');" onmouseout="changeCSS(Link1, '#profileNav p');">Link1</p>
I get the error "Link1 is not defined" though.
Anyone know why this is happening? Or a different way to achieve my main goal which is to change Link1's css class.

I'm using a simple script that moves a DIV from one location to another when the user mouses over it. The problem is, I want the user to have to click the div for it to move and then click it agin to move it back. I've been trying to find a simple solution without luck. Code:

I have a nice little script that changes a company's logo (displayed in a side bar) when the user mouses over a part of an image map.
Here is the basic code:
My question is, how can I get three different images (company logo, weekly price chart and monthly price chart - all of which are in an image folder on my server) to change on this one mouseover event. I tried replicating the function three times and altering each function's name but that ended up screwing the whole thing up.

I currently have a normal link like Code:<a href="http://sitepoint.com" class="link">sitepoint</a> and when a user clicks on it I want to be able to change the "link" class to a different class. However, I don't want to add anything to the actual link html. Is it possible to do this using javascript without modifying the original link code?

I am trying to dynamically clear the value of a form input field and then submit the form.When I used $('#my_field').val('') to clear the field, it was cleared on the screen but when the form was submitted the original value of the input field was posted.My browser is FireFox and I can see using FireBug that when the field is cleared, firebug is still showing the html code with the old value. E.G. <input type="text" value="old_value" />The same situation occurred if I used $('#my_field').attr('value', '') to clear the field.The same situation occurred if I actually changed the value of the field rather than just clearing it.To work around this problem I ended up using the $('#my_field').removeAttr('value') to clear the field before it was submitted.

I am a complete novice when it come to Javascript. I copied the script for displaying random images at a specific interval (from javascriptkit.com). I would appreciate knowing whether the following is possible:
The pages are based on tables, so the parts that change are all cells.
1. Can I define text instead of an image in the array? i.e. can I have the image change to say an apple in one cell and the next cell have text explaining what an apple is?
2. Would it be possible to put a countdown timer for when the image/text is going to change?

Ive got a small image of a power button and when pressed the inner section on the button changes to yellow, but when its pressed down Im also trying to get part of my H1 (main header logo title) to change to yellow.
Ive created a span with an id surrounding the letters of the H1 that I want to change, the id being : "power";
The javascript that I have come up with so far and works is as follows:
<img id="poweron" src="http://www.sitepoint.com/forums/images/power.png" alt="Power on button" onmousedown="this.src='images/poweron.png';" onmouseup="this.src='images/power.png';"/>
I understand Im not really supposed to be using inline JS, and I know Ive got to create a function for the onmousedown event to trigger changing the H1 text, so am I under the right impression that the JS so far written is redundant and will have to be re-written so thats contained within a script placed just before the closing </body> and an external script for invoking the main function ?

I have a table with two columns and two rows in it. In the upper left corner, I
have a logo image for my company. In the top right column/cell, I have some
navigational stuff, no big deal. In the left cell in the 2nd row, I have a list
of anchors of different songs I am producing - something like this:
<A HREF="jamison.mp3">Jamison</A>
<A HREF="tlw.mp3">The Long Winter</A>
<A HREF="summer.mp3">It's Summertime</A>
....
....
The cell on the right, 2nd row is empty at the start.
On the 2nd row, 1st cell, where the anchors are, on a "mouse over" event, I'd
like to display song lyrics and information regarding the song in the right
cell, 2nd row as the user moves the mouse over a given anchor.
What is the best way for me to do this? There are a couple of things/issues I
can think of right away:
1) Let's say there are 20 anchors in the left column. Let's say that some of
the songs' lyrics are quite lengthy and extend past the height of the cell at
row 2, left column. How would the system know this in advance (this will make
more sense with question #2 below)? Perhaps tell it some type of maximum height
you know will never be reached or something?
2) To me it doesn't make a lot of sense to include all this text in the main
HTML file since a majority of the time, the user(s) will never move their mouse
across ALL the anchors, only one or two. Seems to me there should be some way
of "loading" them as soon as the mouse over event occurs.

I am trying to capture the onmouseout event on an option. I know there
is no mouseover/out event(in IE 6), therefore I ask, does anyone have
a work around?
Essentially what I need is a tooltip that displays the entire contents
of a dropdown/select if the contents of the option are getting
truncated due to the width of the dropdown/select. And I want to do
this while the dropdown/select is expanded.
Can some recommend an open source 3rd party control if there is no
solution when using the standard select?

Heyho. Well I'm rather new to JavaScripting, so don't be harsh on me :).
Well I'm trying to make a 'onMouseOver & onMouseOut' event, where you hold the cursor over a image, it will change to another.
So, here is my code:
It works fine when I use it for 1 picture, but it really mess up when I use it more then 1 time.

I made this neat little script to make a rollover image on an image map:
<head>
<script>
var clipNums=new Array(21,81,95,155,170,230,243,317);
function positionMap() {
document.getElementById('over').style.left = document.getElementById('off').offsetLeft;
document.getElementById('over').style.top = document.getElementById('off').offsetTop;
}
function imgRoll(i){
document.getElementById('over').style.clip="rect(0 "+clipNums[i]+" 19 "+clipNums[i-1]+")";
document.getElementById('over').style.visibility='visible'
}
function imgOut(){
document.getElementById('over').style.visibility='hidden'
}
</script>
<style>
#over{position:absolute;visibility:hidden;z-index:10;}
</style>
</head>
<body onload="positionMap();" onresize="positionMap();">
<map name="a">
<area shape="rect" coords="21,0,81,19" href="#" onmouseover="sh(1);" onmouseout="mo();">
<area shape="rect" coords="95,0,155,19" href="#" id="mnu1" onmouseover="imgRoll(3);" onmouseout="imgOut();">
<area shape="rect" coords="170,0,230,19" href="#" id="mnu2" onmouseover="imgRoll(5);" onmouseout="imgOut();">
<area shape="rect" coords="243,0,317,19" href="#" id="mnu3" onmouseover="imgRoll(7);" onmouseout="imgOut();">
</map>
<img src="/link_imgmap_on.gif" id="over" usemap="#a" border="0" width="322" height="19">
<img src="/link_imgmap.gif" id="off" usemap="#a" border="0" width="322" height="19">

I have a simple mouseover menu using style.visibility property(hide/show). My question is how do I hide all menus other then the one I moused over? Also I have a onmouseover and onmouseout for the image that shows the menu when you mouseover it, how do I keep the image showing when moused over it and mousing over the menu that it shows?

I have two scripts that seem to be overriding each other. they both seem to use the onmouseover function to trigger actions that are vital to each script. to be honest I'm not sure if this is really what happens but when I disable one one works, when I disable the other, the opposite works. so right now it's my best explanation :-p. oh and it's definitely not any scripting variables interference.
I'm using Milonic drop down menu (the trial for testing) and another small piece of code that I've attached that does on mouse over tip bars.
what I'm wondering is if there is a way to make them both work without...breaking one or the other. or if I should just find another solution, which is proving difficult because I can't find one that's super simple and as nice as this one.

I have the following script which loops for all alphabets and displays images. I wanted to display a different image onMouseOver but having problem with the syntax.
<script language="javascript">
var alphaArray= new Array('a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r', 's','t','u','v','w','x','y','z');
var i=0;
for (i=0; i<26; i++)
{
document.write('<img src="images/'+alphaArray[i]+'.gif" width=16 height=28 hspace=0 border=0 alt="'+alphaArray[i]+'" id="'+alphaArray[i]+'-horz" onMouseOver="document.images[''+alphaArray[i]+''-horz].src='images/'+alphaArray[i]+'-over.gif'">');
}
</script>
I am getting "Expected '('" error with this code
onMouseOver="document.images[''+alphaArray[i]+''-horz].src='images/'+alphaArray[i]+'-over.gif'"

I am designing a website with an imagemap as a navigation pane and I want an effect to happen when certain parts of the image are rolled over by the mouse. I want to switch the imagemap image to a different one (one which highlights the rolled-over bit) depending on which bit gets rolled over. (Sorry if this is confusing) This is my code:
HTML Code:
<img id="Image-Maps_9201104271548429" src="imgmap.jpg" usemap="#Image-Maps_9201104271548429" border="0" width="960" height="90" alt="">
<map id="_Image-Maps_9201104271548429" name="Image-Maps_9201104271548429">
[code]....
This doesn't work, the image stays the same no matter which bit the mouse rolls over. Can you please tell me where I am going wrong? I don't know javascript and am following instruction from this website.

I have been writing a practice sliding div navigation script. I am finding
myself in the position where I need to force a div into showing the hover
behavior defined in css.
So my question is this. If I have two divs, is there a way to make the
second div display its onmouseover behavior when the mouse is over div 1?

I know I can use the status line to display a message 'on mouse over'.
However, I would prefer to have the message displayed near the cursor
location, but couldn't figure out how.

Why doesn't a onmouseover function work in a function?
(It's prob due to my code being wrong more than anything else!)
I've got the following code (snippet):
<!-- Begin
var image0 = new Image(); image0.src = "blank.jpg";
var image1 = new Image(); image1.src = "map.jpg";
// End -->
function swapTheImages()
{
image0.src=Ƈ.jpg' image1.src=ƈ.jpg' image2.src=ƈ.jpg'
}
When I do an onmouseover and call the function, it doesn't work.
BUT if I put the code in directly - it works!

I've been going out of my mind trying to get this to work, and now I'm out of time! It seems like it *SHOULD* be simple! All I am trying to do is get all of the <li> items that belong to a particular UL ID, and change the class name onmouseover. I've cut down the code to bare-bones to try and isolate the problem. I can get it to work if I use unique IDS for each list element, but that seems silly. The latest piece of code I am working with:
<script type="text/javascript">
var mylist=document.getElementById("mylist")
for (i=0; i<mylist.childNodes.length; i++){
if (mylist.childNodes[i].nodeName=="LI") {
mylist.onmouseover=function() {
[Code].....
