I've been working on a javascript function to read one of my html classes and then adds another duplicate class to the html. It's working now but the problem is that im using gelementbyid. So i have to change what i would like to specify as a class as an id. Which is not very standards compliant html. Is there any way around this? Code:
View 15 RepliesI want to restrict getElementById to search children of a specific element instead of searching the entire document, in the same way that I can do getElementsByTagName using a specific element as the parent.
In this particular instance the parent is a table and the elements I'm interested in are all TDs, so I did the basic getElementsByTagName('TD') off the table and looped through this array checking the IDs. However, I'm suspecting that the browser can do getElementById faster than I can do a loop in javascript. Is there a neater way to do this? For now, I'll settle for IE-only solutions, though it would be nice to have things work in generic browsers.
I keep getting an error stating "getElementById("ballElement") is null, but I have a div with that exact id. I have looked at the JS script before that line, but found no errors there either. Please take a minute to see if you find something.

I know you can reference certain elements buy its ID many different ways! Is it possiblle to do the same with class names? I know I have seen javascript manipulating class names somewhere, .className or something?

/* 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 want to use variable names while accessing css classes. Here I am giving example about my query

variable temp will change dynamically. as per temp we need to acces horzontal1 or horizontal2 divs.
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?
This below would be my ideal code.... if it worked.
<html><head><script>
function mouseDownClass(o){
this.o = o;
this.handleMouseUp = function() {
alert(this);
}
//treating this section as the constructor (which sets up the mouseup
listener as the method of an instantiation, ideally)
document.body.addEventListener("mouseup",this.handleMouseUp,false);
}
</script></head><body>
<button id="b1" onmousedown="new mouseDownClass(this,event)">Down
-> Up</button>
</body></html>
alert() is showing 'this' to as: [object HTMLBodyElement] whereas i'm
looking for it to show [object Object], (On Firefox at least),
referring to the object instantiated when the mouse goes down on the
button. I'd appreciate anyone who can help me here?
I need to remove class to prevent triggering of click function for elements
Have:

second click on element "blabla" triger again click function. why?
Basically i have a good experience and knowledge with prototype.js library and also at the same time i am willing to get deeper into jquery.
I very much use oops concept now a days in almost every problem i solve using javascript, and was doing with prototype's feature to create classes and objects. Since i am now looking to get deeper into jquery, i was looking to find similar feature in jquery as well. I suppose jquery must be having a feature to create classes and do inheritance programming, but i couldn't find the way. My question to the forum is, Is there any option/feature in jquery which helps us to create classes and objects of our own probably with the support of inheritance?
So I understand you can do:
$(".className").xxx.
Is there an easy way with jquery to have it match 2 classes. So maybe I only want the action to take place it the element has class1 and class2.
$(".class1" , ".class2").xxx
The above is close to what I would like, but thats if any of the 2 classes match, go. I need it to be both. I can probably do this with some basic javascript logic.. just figure there may be a function for this already.
I'm using the latest version of JQuery. How do write an expression to match multiple classes, but only for elements that are inputs of type="button" or type="submit"? I have figured out how to match multiple classes with the expression .

The intended effect is for spans of class "checkbox", which should each contain one checkbox, to have the class "checked" if the checkbox is checked, "unchecked" if not.
When I load the page and do an "inspect element", the spans have class "checkbox" but none of them have either the class "checked" or "unchecked".
