I have a set of div elements cached inside var divs = $('#myDivs'). Suppose another div comes along that i want to add (push) to the group. is there a simple method for doing this without selecting ones already in the group for a second time?

Let's say I have a Javascript object that looks like this:

events: {

There's an object:
foo = new Object();
and a property called 'bar' with a value of 1 is to be added to it using
JSON. If I try the following it only demonstrates my ignorance:
var str = "{foo:{bar:1}}";
eval(str);
alert(foo.bar) // gives undefined
Could someone please explain what I'm doing wrong here?

modifying an existing function which controls the highlighted states of a multi level js accordion menu. I have had to use javascript due to certain css elements not working in safari browsers.My problem is due to the multi level aspect as when a sub link is clicked, the parent link above it then deselects. I need the parent link to stay active when its sub links are clicked and only deselects when a link outside of that list is clicked upon.I understand the theory of adding a conditional statement but simply don't know how to apply it correctly within the functionHere is the existing function which tells a link to be active or selected:var Lst;
function CngClass(obj){
if (Lst) Lst.className='.topnav';

The script below is configured as an onmouseover & out fad-in url script. It's been configured it so that the fading of links only occurs in areas with the class name "fade". My first and simplest request is that someone has a quick look and changes the code from class name "fade" to class name "descriptions". i would do it myself but the word fade is also used for other variable names within the script (etc) and i'm not 100% sure which names to change and which to leave
The second aspect I need help with may be somewhat more challenging.
The script currently fades the TEXT of the link from one color to another. I need it to fade something else. luckily i think the modifications to the script might not neet to be that extensive. Here's what I need.
Instead of the color of the text fading in & out, i need the color of the boder to fade in & out. Here's an example:
i need the properties of the link to go from
text-decoration:none; border-bottom:1px solid FFFFFF;
to finish at
text-decoration:none; border-bottom:1px solid FFB903;
the only change is the color... so i figure all we need to do is create a color variable and place it in the code, like so:
text-decoration:none; border-bottom: Ƈpx solid' + 'color'
and then simply have that color variable increment using the startColor and endColor variables found below Code:
i have a image around 995x700. and i'm about to change up a couple things on a site i'm working on and want to add a mouseover event (or something like that) to it. i certain areas, i would like the user to mouse over and see a new image rise up in front of the existing image, and then go away when they "mouse off" (i guess that's the term). i know there is a possible way through jscript or ajax.

I'm making some jQuery UI elements, and once an element is created, I want to add some custom functions and variables - I don't want to clutter up other jQuery objects by putting the functions in all jQuery objects, and obviously, the variables need to be different between different objects. However, the issue is, when I re-acquire the item, I won't have access to the variable any more.
That was probably confusing. Another way of putting it:
(function($){
var _MyUI_id=0;
jQuery.fn.MyUICreate = function(opts){
this.each(function(){
var obj=$(this)
//... code to turn the object into a MyUI object omitted to be concise
obj.MyUI_id = _MyUI_id;
_MyUI_id++;
}}
})(jQuery)
//now, create one
$('#some_div').MyUICreate({});
//The desired effect would be to give me the id in #14, instead I get 'undefined'.
alert($('#some_div').MyUI_id);
My 'solution', is to create an object variable in jQuery.fn called 'Collections'. It's indexes are the names of the new types, and each contains an object, the keys of which are the IDs of the UI elements that are converted to the type, and the values the jQueries objects. This is not only hackish, but it has a LOT of potential bugs. The code for this would look like:
This is in the 'create' function, at the end.
jQuery.fn.Collections.MyUI[obj.attr('id')]=obj;
This is outside of the create function, but within the (function($){...}) scope.
//jQuery.fn.Collections is set to {} in another file.
jQuery.fn.Collections.MyUI={};
jQuery.fn.GetMyUI(id){
return jQuery.fn.Collections.MyUI(id);
}
This will allow the first block of code to work as desired, but it inserts a whole new set of bugs. What are the common ways to achieve what I am trying to do?

I inherited a site that has jscript and html content. The site frame (top and left nav) are controlled by the jscript file. Most all of the content that is displayed when links or topics are selected is placed in the center of the page. I need to put some scrolling text in one of the top frame blocks, (the section that is java script file).
function buildMenus(){
var headerString = "";
var leftnavString = "";
var footerString = "";
[code]....
I have a couple of jscripts that do the scrolling I want, I just need to know how to insert it in the above section.
I have the following object:
var wDefaults = {
"skin":1,
"pagewidth":"960px",
"c1col":[
{"wid":"w001","pcol":0,"wpos":0,"wclosed":"false","wcollapsed":"true"}
],
"c3col":[
{"wid":"w002","pcol":0,"wpos":0,"wclosed":"false","wcollapsed":"false"},
{"wid":"w003","pcol":0,"wpos":1,"wclosed":"false","wcollapsed":"false"},
{"wid":"w004","pcol":0,"wpos":2,"wclosed":"false","wcollapsed":"false"},
{"wid":"w005","pcol":1,"wpos":0,"wclosed":"false","wcollapsed":"false"},
{"wid":"w006","pcol":1,"wpos":1,"wclosed":"false","wcollapsed":"false"},
{"wid":"w007","pcol":1,"wpos":2,"wclosed":"false","wcollapsed":"false"},
{"wid":"w008","pcol":1,"wpos":3,"wclosed":"false","wcollapsed":"false"},
{"wid":"w009","pcol":2,"wpos":0,"wclosed":"false","wcollapsed":"false"},
{"wid":"w010","pcol":2,"wpos":1,"wclosed":"false","wcollapsed":"false"}, {"wid":"w011","pcol":2,"wpos":2,"wclosed":"false","wcollapsed":"false"}
]}
First, how do I access a single value? I've tried some of the examples I saw on the forum, but nothing happened. The alert did not fire:
alert(wDefaults.c3col[0].wid); //first try
alert(wDefaults.c3col.0.wid); //second try
var obj = wDefaults.c3col[0]; //third try
alert(obj.wid);
The nested objects are the properties for widgets within a portal. After the user moves around the widgets, I need to update the object, putting the widgets in a different order within c3col and updating the values saved in pcol, wpos, wclosed, & wcollapsed. I also may need to add or delete an object, for example, delete wid=w003 and add a new one called w012.
My logic would be:
for each widget on the page
found = false
find the object in c3col where wid == x and update its other values
. set found = true
if found == false then add a new object to c3col with x & its properties
end for
for each object in c3col
if that wid isn't found in the list of widgets on the page, delete it from c3col
end for
sort the objects under c3col by pcol and then wpos
The red parts are the ones I'm unclear about how to do it. My basic questions are:
(1) How do you access a single nested object?
(an object within c3col, find and change its values)
(2) How do you add a new nested object to an existing object?
(add a new object to c3col)
(3) How do you delete an nested object?
(remove an object from c3col)
(4) How do you sort nested objects?
(sort the objects in c3col by pcol and wpos)
Did any one use bind inside for-in loop? In my case it never work correctly whatever I do.I'm trying to go through a collection of objects using for-in and bind MouseEnter handler for each object.What happened is the handler I bound to the last object works for all the objects?!

I was under the impression that I and object/associative array could have other objects as the keys for properties. That is, I should be able to set myObject[anotherObject] = 1. However, while this seems to work at first glance, any new object I set as a property key overwrites the first one.Here is the result of me testing in my Chrome console:
> var obj1 = new Object();
> var obj1.someProperty = "test"
"test"

I have an array of objects that I would like to sort through and "join" objects that are the same. And if they are the same, I need to sum up the number value given for those two items. So I guess Im sorting through and maybe even recreating this array to get rid of duplicates while I tally quantities. see the screenshot of my array of objects to help understand better. The highlighted 'sPSPN' would indicate that it is a duplicate item and its 'fUnits' need to be totalled. in the end I would have a total of 3 objects, because 'sPSPN'= BT-221-44 would now be only one object with 'fUnits' = 35.

Trying to figure out OO programming for JavaScript and I'm totally lost.
Here's what I'm trying to do:
