Target Certain Classes In An Array?
Jan 10, 2010
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 am trying to understand somecode. I don't think I am understanding everything correctly. Can someone confirm or add to my understanding?
Here is the code, below is my explanation:
- CODE 1 - is saying if the the class subnav_dd is called on an anchor tag on a li, then make the function in the if statement "live". (Live in a sense binds the function to the condition, but unlike bind it allows the condition to be used more then once. ) So if the class subnav_dd is the parent, and has a class of .dis then prevent anything below it from firing. CSS - If code 1 is true, then I will only get the first li to fire, the remaining ones will not.
- CODE 2 - This one is a little tricky. Function ToggleOptions takes 3 variables (target, array, state). The condition is if the div subnav + target have siblings, then check to see how many siblings are there. Put the amount of siblings into an array, then check the state of each sibling. I don't completely the rest of it.
I think if the div subnav is called and something is found in the array then the class dis is either added or removed. Then what? I don't understand why I still need the else that adds a class to #subnav_ +.target

I am using the following javascript on the target page to open it as top location from within an iframe, which is working ok.
<script type="text/javascript">
if(self!=top) {
top.location.href=location.href
}
</script>
However my problem occurs when the user uses the browsers back arrow to return to the previous page, the script executes again returning them once more to the page they have come from. Is anyone aware of a work around to this problem as it would seem there isn't one? perhaps even a better solution for opening the target page from the iframe as top location. This is really causing confusion for users, and I really need to get the issue fixed.

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?

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?

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?

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.
