Changing Class Attributes
Sep 3, 2002
I need to change dynamically how a class is displayed, my site (with out going into detail) interprets saved info from the user (its saved through perl) in a *.js file, then views it through template *.htm files drawing on js files after loading.
The thing is I need to allow for several settings like font type size and color, (things that could be held in style sheets) but then save in their js file a number representing this and load it when the template page is opened.
I have two possibilities to answer this
1, instead of using classes I could use Ids - but using 1 id for what could (hypothetically) be an endless string of elements seems real messy, I don't even know if it would work.
2, I read somewhere I could dynamically generate style tags with the classes defined, but I can't find where I read this..

I'm currently working with Javascript to build some "dynamic" tabs. Basicly, the tab "onmouseover" and "onmouseout" event have been overriden to change the tab's css class.
Here's the class:
function HtmlTab(id)
{
this.id = id;
this.tab = document.getElementById(id);
this.cssover = "over";
this.cssout = "out";
this.tab.onmouseover = function()
{
this.className = this.cssover; // NOT WORKING
}
this.tab.onmouseout = function()
{
this.className = "gen";
}
}
My problem is, I cannot access my HtmlTab class attributes from the this.tab.onmouseover function.
Anyone knows a way to fix this?

I need to be able to get the css attributes that a particular class defines. Such that if I have a class called "SomeClass" I want to see if it defines the attribute "position". I've tried using .css on an element that has the class, but of course that picks up the defaults and any inheritance.

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 using the JK Pop-up image viewer, from JavaScript Kit for an online library exhibition I am making. I can change the background color of the pop-up window to the color of the main website (Dark Blue) however, I can not seem to find away to change the color or font style, of the text that appears in the pop-up window.I have tried using css to no success, the only way I can seem to do it is by wrapping the text for each image in the deprecated <font color> tag which i obviously don't want to do.Here is the code below:
<script type="text/javascript">

I'm extending the number of rows of a table by cloning the last row (=newLastRow). Each row has a single input tag in it, with a name which includes the row number and an onclick function call which passes the row number to the function:<input type='text' class='clickable' name='inp8.1' size='20' value='xyx' onclick='toggle("table8");'>The new cloned row has an input tag with the same parameter value as the cloned one, obviously. I need to increment this: name='inp9.1', 'toggle("table9")'.y question is simple but I'm just starting with DOM: how do I refer to the input tag in the newLastRow so I can change these values?

I'm not really much of a javascript programmer, but I occasionally use javascript that I've found here and there. But I'm unable to find anything that helps me in what I'm trying to do now.
I regularly use a snippet of code that pops up a small window to display an image or a very small html file.Using the window.open() function, I'm able to disable scrolling, resizing, etc., and size it to my needs. I'll have a window.close link somewhere on the page. But in my current project, my customer's page has several links related to other companies. When you click on the link, an that company's ad pops up in a small window. At this point, the viewer can simply close the window, or they should be able to click on the ad and be taken to that company's website.
I'm able to have it close the window and open that new url in the parent browser window, but my website customer doesn't want their site to go away. They want the new company's website in a new window.
Or I can simply NOT close the popup window, but now the new company's website is in a relatively small browser window, unable to scroll, resize, etc. Is there a way for me to somehow modify an existing window with an onclick directive - something similar to the window.open() function, OR open a new browser window with window.open() AND close the popup window? If I haven't made myself clear, let me know and I'll try to explain myself better.

I've got a set of input fields of type text, that I want to change to hidden. The fields are identified by the class name .navtitle. Here is the code I've written to try and change the fields:
Code JavaScript:
$(".navtitle").each(function() {
this.type = "hidden";
});
This works fine in Firefox, but doesn't work in IE, and worse still, breaks all of the other JQuery code I've got as well.

I'm currently in the process of making a spreadsheet like webpage and it all working fine... However I have been using setAttribute and removeAttribute in order to dynamically change a table cells onclick property.
This of course does not work in IE7 etc and I've been banging my head against a brick wall trying to come up with a solution that will work in all browsers but I just can't seem to get it to work with using methods such as...
I get all sorts of not implemented, type mismatch errors when I try to use the above.
Below is the setAttribute code which works.

I need to change the class of the 'a' tag within the li that has the nested ul e.g
<div id="menu-container">
<ul class="main-menu">
<li>Link 1<a class="menu"></a></li>
<li>Link 2<a class="menu"></a></li>
<li>Link 3<a class="menu"></a>
<ul class="sub-menu">
<li>Sub Link 1<a class="active-menu"></a></li>
<li>Sub Link 2<a class="menu"></a></li>
</ul>
</li>
<li>Link 1<a class="menu"></a></li></ul></div>
I need to change it to "active-menu" and the nested a to "menu". I cant change the HTML at all, I wish I could.

I have the following: <div class="unselected" >content</div>
I want to change unselected into selected when calling a function. The ways I'm finding to do a class name change is using a clicking:
$('.unselected').click(function(){
$('.selected').attr('class','unselected');
$(this).attr('class','selected');
});
But I don't want to click, I need to do it by calling a function ..

I would really love some sort of javascript observer to automatically add/remove a class to the labels on my page, depending on wether their checkboxes are checked or not. As well as adding those same CSS-classes to the checkboxes already checked on document load.This would be possible in javascript, wouldn't it?

I am making a little tool for a client of mine, which will include a very large list. Now in PHP I've written that is should divide everything in the letters of the alphabet. So Now I have a list from A through Z, but I want it collapsed, else you would still have a very large list. I want my javascript to change a class name from 'folded' to 'unfolded' so css can do its job hiding and showing the list. See below code (you can change things if you like):
PHP Code:
<?php
$alfabet = 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');
?>
<html>
<head>
<title>Lijst met verenigingen</title>
<script type="text/javascript">
var name;
function folding (name){
if (document.getElementById(name).getAttribute("class", "folded")){
document.getElementById(name).setAttribute("class", "unfolded");
} else {
document.getElementById(name).setAttribute("class", "folded");
}}
</script>
<style> .....

I've got a list of modules, and when I click on one of them it expands displaying the content. When you expand them, a little image on the right changes from a down arrow (v) to an up arrow (^), but it's changing on all of the modules rather than just the one.
Here is the website: [URL]
It's pretty obvious what my question is; how do I get it so the image only changes on the module that you expand?
Here's the code for the moduleToggle function:
function moduleToggle() {
$('.content').hide();
$('.title').click(function() {
