Use Script To Change CSS Pseudo-classes?
Mar 2, 2010
I am trying to use javascript to replace colors in css classes with hex values from a color selector (jscolor). It's working for basic classes and ids, but the stylesheet I need to work with contains contextual CSS and pseudo-classes and I can't figure out how to reference them. (The stylesheet I'm working with is pre-defined and I can't change it.) [code]...
How do I reference these? I don't know Javascript that well, I'm just a prototyper -- and I'm stumped!

is there a way to force a pseudo class on an element?
something like navObj.style.hover = true;
I haven't been able to find anything, but what I'm trying to do it make it so if you click on a button or whatever it keeps its active state until another button is clicked.

I want to create a sort of pseudo click event, that is needed to launch a slideshow.when the page loads it would fire off a function that creates a clicks event, as if the user has clicked on an element, when in fact that they had not. i saw in the jquery documentation with the click function, you could click on one thing and then another click event would be created via another element.that's close to what i'm trying to
$('#other').click(function() {
$('#target').click();
});

console.log(thisParentIndex);
$(this).parent().parent().find('div.line:gt(' + thisParentIndex + ')').hide();
this does not appear to work..

I'm creating a list of items which visually look like checkboxes. They will work similar to the ones used on eBay that allow you to select only new/used items. Mine are a little simpler though. Here is the markup:
<li>
<a href="#" class="catHeader trigger">Designers</a>
<ul class="nav-ul toggle_comtainer">

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.

I would like to set the link's "visited" pseudo-class with javascript
without clicking on the link. My goal is to update the link's color
(previously set in the CSS file) to be "visited" without actually
clicking on the link and then clicking "back" in the browser.
Does anyone know how? Here are the following things I've already
tried to no avail:
var obj = document.getElementById("idOfMyLink");
//obj.visited=true; // NO
//obj.style.visited=true; // NO
//obj.click(); // NO, performs a click and takes me away from
current page
/*
// Setting the src of an iframe on the same page, trying to
"stuff" this URL into browser's "History"
var theFrame = document.getElementById("myiframe");
theFrame.src = obj.href;
// NO. The iframe does go to correct URL, but the link's color
doesn't update.*/Any ideas?

I've discovered the following problem while building an APP:
/* Code Start **************************/
// Definition
function cClass_prototype_prototype()
{
this.array = new Array;
this.className = "cClass_prototype_prototype";
}
function cClass_prototype()
{
this.className = "cClass_prototype";
}
cClass_prototype.prototype = new cClass_prototype_prototype;
function cClass1()
{
this.className = "cClass1";
}
function cClass2()
{
this.className = "cClass2";
}
cClass1.prototype = new cClass_prototype;
cClass2.prototype = new cClass_prototype;
oClass1 = new cClass1();
oClass2 = new cClass2();
// Testing
alert(oClass1.array)
alert(oClass2.array)
oClass1.array.push(1);
alert(oClass1.array)
alert(oClass2.array)
/* Code End ****************************/
If you will execute this code you will see that pushing an value into
the first class instance array property cause changing value of the
second class instance array property.
Is it possible to have array values not connected to each other?
I would like to avoid defining "array" property in cClass1 and cClass2
(in this case it would work the proper way) and have them defined only
in third-level parent class cClass_prototype_prototype.

I am building a menu system and I cannot seem to differentiate between the different class elements in my menu. My problem is that when I click on one of the 'buttona' elements, all the ul's with 'effect' fire - does anybody know how to differentiate so that if the one li is clicked just thecorrespondingul with open and close?
<ul> <li><a class="buttona" href="#">Application one</a>
<ul class="effect"> <li><a href="#">Add</a></li> <li><a href="#">Edit</a></li> <li><a href="#">View</a></li>

I am using nested jQuery UI Tabs in my application. My problem is that I want to style them all differently. I can't seem to get this to work, as they all seem to use the same CSS classes.
Is there some way to get the tabs to use different classes, or some other way to do this?

I have a navigation pane with 4 links. Two of these links show collapsable submenus. When one clicks a link, I want the CSS class of that link to change. For the two "real" links, I've just changed the class on the page itself. For the two collapsible menus, I'm trying to employ javascript.Ultimately for these two links, I want the class to change when clicked, and change back when clicked again.Here's the code for the page:
<div id="navigation">
<ul>
<li><h3><a href="javascript:;" onclick="changeclass(this);" onmousedown="toggleSlide('slidemenu');" class="colmain">COLLAPSIBLE MENU[code]....
1. Seeing as I've been working with javascript for a grand total of six days so far, could you explain the best way to make my code work? What's the significance of colstatus=obj?
2. The javascript works if I leave out the else statement. It will change the class after being clicked, but, of course, doesn't change it back. However, if I click the other collapsible menu, it will change as expected, but the first will revert back to the original class. Why is this happening?
3. Seeing as the code is adopted, I have no idea what /*<![CDATA[*/ and /*]]>*/ mean. Would you explain?

In the exercise I have 5 elements (lets call them input fields), 3 of which I have given a class of 'red' to. What I can't figure out is how I select just the input tags with the class='red' attribute on them by using the getElementsByTagName. I understand that getElementsByTagName puts all the elements into an array, but how do I target the ones just with the red class?
I'm sure there is a way of doing it using the className property but I can't seem to get anything working?

I have a jQuery script that changes the background color of odd rows in a table. If a row has class "new", though, it won't change it:
Code:
$(document).ready(function() {
$('tr[class!=new]:odd').css({'background-color':'#ddd'});
});
Is it possible to specify another class (together with "new") to which the script should not change the color? If yes, what's the syntax?

There are lots of JavaScripts and PHP scripts for making tables with alternating row colors. I'd like to know if there's a way to use JavaScript to give a table alternate row CLASSES.
My ultimate goal is to cut down on the html and gain more control over my table. I have a PHP script that gives me alternate cell colors, with different colors in each of two table columns. But it's just too complex to work with. Code:

I've been using the prototype.js library[1] to create classes. Something like:
var Sortable = Class.create();
Sortable.prototype = {
initialize: function(element) {
//...
},
// more methods...
}
All of my methods are instance methods. What is the tidiest way to
create class methods and variables?
