Apply Style Changes To A Whole CSS Class

Sep 19, 2005

I would like an event to trigger a change the style of all the elements that
belong to some CSS class.

I know it is possible to change the class of an element, for example with:

<script language=javascript>
function changeclass()
{document.getElementById(id).className="class_id";}
</script>
<input type=checkbox onclick="javascript:changeclass()">

But this can only change one element. I would like to change the
"property:list" pairs of a CSS class, so that changes can apply to more
than one element.

Is it possible with javascript?

Apply A Style Expression During Runtime?

Feb 10, 2009

I need to set the position of an element to fixed using JavaScript at runtime.
Sadly, IE6 does not know this value, so I want to use the following workaround:

Instead of setting the position to fixed, I set it to absolute for IE6, and the top value needs to be the following expression:

Code:

top: expression(0+((e=document.documentElement.scrollTop)?e:document.body.scrollTop)+'px');

Sadly I have no idea on how to apply this expression to myFixedObj.style.top! I tried it using

Code:

myFixedObj.style.top=expression(0+((e=document.documentElement.scrollTop)?e:document.body.scrollTop) +'px');

and

Code:

myFixedObj.style.top="expression(0+((e=document.documentElement.scrollTop)?e:document.body.scrollTop)+'px')";

Apply CSS Style For Table Row If Radio Button Is Clicked

Jun 6, 2007

I am trying to make it so that the style "RowSelected" (embedded
below) is applied to the table row from which the radio button is
selected, and then removed when a different radio button is clicked.

Right now, the below code kinda works. The javascript was copied from
an example on a website from which I forgot the URL. It only applies
the style properties to the label text, and not to the row. Code:

Apply Selected Class To One <li> When Another <li> Is Clicked On

Sep 4, 2010

I currently have a script that dynamically adds a css class called "on" to a menu item once it is selected, turning that link red to show that it's active. Here is the web page: [URL] As you can see, if you click on "Dimmer" or "Pol Pot's Birthday", or one of the three Patriotville scene links (1, 2, or 3), those links stay red. But what I need to happen is that when the user hovers over OR clicks on "1", "2", or "3", the word "Patriotville" also turns red along with those links. Here is the current code:

<script language="JavaScript" type="text/javascript">
/*<![CDATA[*/
var Lst;
function CngClass(obj){
if (Lst) Lst.className='';
obj.className='on';
Lst=obj;

Apply CSS Class - Selected Item As The Background Color Won't Change?

Apr 28, 2009

This is for an online quiz that collects selected answers through hidden checkboxes, and when a checkbox is selected the javascript changes the background of that selected item. However the problem is when javascript is disabled the whole thing won't work because the checkboxes have a class of .hide which, obviously, hides them and the user can't see that they've actually selected an item as the background color won't change. So I was thinking that instead the javascript could apply the class of hide to the input. That way if it's disabled the checkboxes will show.

<style type="text/css">
.hide { display:none;
*display:block;
*margin:0;
*padding:0;
*width:0px;
}
</style>

Using Javascript To Apply One Element's Style To Another Element

Jul 27, 2007

Code:

test.div.style.backgroundImage=test.div2.style.backgroundImage;

It works if I specify the actual background image within the function, so I know the image is there, and I know it's been properly assigned to div2, but div1's background image doesn't change.

I have a element that uses a class, like:

Running OnClick To Change Href Class CSS Style

Jan 12, 2010

I am using this javascript code to run 'onclick' to change my href class style. It works to change the style, but when I click on the next menu item, the previous one is not reverted back to how it was previously, but the formatting is stripped away leaving the link purple with no background image. How do I get it to revert to the original class which is set?

Here is the javascript :-
<script language="JavaScript" type="text/javascript">
/*<![CDATA[*/
var Lst;
function CngClass(obj){
if (Lst) Lst.className='';
obj.className='menu1';
Lst=obj;
}
/*]]>*/
</script>

Here is the relevant CSS :-
.menu {
background: url('../images/productblack.jpg') repeat;
width: 100%;
line-height: 24px;
float:left;
display:inline;
font-family: Verdana;
color : #ffffff;
font-size: 8pt;
text-decoration: none;
text-align: left;
font-weight:bold;
} .....

Here is the HTML :-
<div id="masterdiv">
<div onclick="SwitchMenu('sub1')"><a class="menu" onclick="CngClass(this);" href="javascript:nothing()"> 
RESISTORS</a></div>
<span class="submenu" id="sub1">
<a class="productsubmenu" href="resistors.html">Surface Mount</a><br> .....
Here is a working page with it (the product menu on the right) [URL]

Dynamically Style A Link To Its "Active" Pseudo-class?

May 23, 2010

I have strip of navigation tabs, which are marked up as a <ul> and styled to look like tabs with borders and all that. In my stylesheet I have the pseudo-classes for :link , :visited , :hover , :active and all of those work fine.

But I'd like to have the browser highlight whichever link a viewer is currently on by having Javascript activate the already defined :active pseudo-class. What's the syntax for that? Is it even possible?

I've been googling for almost an hour and havn't gotten anything.

JQuery :: Obtain ORIGINAL Style Setting - And NOT Computed Style?

May 5, 2010

My understanding had been that $.css("width") would return the original user selected style, eg "100%" or "10em", and $.width() returned the computed width, always in "px". Not so, following the code through for .css(), it calls something called getComputedStyle and the only difference between the two functions turns out to be a post-fix of "px" on the .css() result - not very useful. I need to know whether my user has called me with a proportional dimension, or a fixed one. How to tell with jQuery?
