Is it possible to search an array without looping through all the elements?
hoping for something like this;
myarray.exists("one")
which may return the element number or a true or false depending if the element being searched exists.
I need to loop through all form elements such as text, radios, check boxes and the like and to save their state in a file. does anyone have JS code to do this ?

I was wondering if there way a way to loop through elements that contain a data key applied by data(). I couldn't find a selector for data keys.
This for instance, I would like to give me the value of 'foo' for where ever it has been applied.
$(document).ready(function() {
$('body').data('foo', 52);
$('head').data('foo', 32);
});

I've lately stepped up a little problem with one of my personal projects that i am working. I'm writing an aspx webpage, which includes web user controls inside it.
The webuser controls are within a web form (id=form1 runat=server) which resides in the
main.aspx page.
1. First of all, is there a way to find a SPECIFIC control inside the webuser control (ascx)
using Javascript in the main.aspx?
2. If not (which i think it is), which is the best way to do it? The snippet i tried was this:

If got problem with .each looping in jquery. im am trying to make a animation with jQuery. And i want to switch between three quotes of the array. and now it only works for the first quote of the array.

Well let's say i have a bunch of div tags with name attribute 'hello'
<div name='hello'></div>
<div name='hello'></div>
<div name='hello'></div>
I want to use JavaScript so that i can look through the array of these div objects.
var helloDivs = document.getElementByName('hello');
var len = helloDivs.length;
.....
So, it works for all the recent version of browsers but not for IE6. There is still about a 10% market share who are still using IE6. What is the workaround for this browser support?
If i were to print the variable len in IE6 says that is 0 and if i print helloDivs, it says it is an object as if helloDivs is a variable that contains an object but not an array of objects.
I am trying to make my own jquery drop down menu. As usual, HTML is like this:
<ul class="menu">
<li class="parent item79"><a href="#"><span>Top Item 1</span></a>
<ul>
<li class="item101"><a href="#"><span>Sample sub-menu 1</span></a></li>

I would like to loop through elements that are NOT disabled. So far my code is:
$("#addlivestock :input").each(function(){
if($(this).find().attr('disabled','disabled'))
{
var getAttr = $(this).attr("name");
[Code]....
When I click a button that code fires. When that code fires all the elements that aren't disabled get disabled. My code does NOT work as expected and I found the problem, which is if($(this).find().attr('disabled','disabled')). how to loop through form elements that are NOT disabled.
I am trying to use "replace" to remove dollar signs and commas from input values by looping through the elements. I'm pretty sure I have to use an array in an array to do so but can't figure it out. Here's what I have:
Code:
function removeStuff(){
for(j=0; j<document.form1.elements.length; j++) {
remove = new Array("$", ",");
for(i=0; i<remove.length; i++) {
newValue = document.form1.elements[j].value.replace(remove[i],"");
}}
alert(newValue);
}
I have an associative array that I need to loop through, allbills,
however, each element in this array requires processing by the user and
I need to capture the users actions on the element and then return to
the next element in the list but suspend looping until I have the users
desired action...
For example,
for(mybill in allbills)
{
GetWhatToDo(mybill); // gets the information about what user wants to
do with the currentBill
}
The problem is that the function "GetWhatToDo" doesn't "block" so the
loop completes without waiting for the users input from GetWhatToDo...
So, my thought was I need to design things more 'event-driven' and
handle things like so:
function handleABill() {
mybill=GetNextBill();
GetWhatToDo(mybill);
}
A "Next" button inside the popup generated by GetWhatToDo will have an
onclick event that calls handleABill again...
The problem is that I can't figure out how to write GetNextBill so that
it maintains the state of the loop through 'allbills', especially since
'allbills' is an associative array and I can't keep track of the array
index. The only thing I can think of is to initialize a regular array
from the associative array and keep track of the index number.

Basically i need it to loop though the array and find who has the highest points / if more than one have the same points so i dance off is required.
I'm a JS beginner and I find looping through arrays with for/in is very easy. Yet I find lots of code examples where array length is used instead of for/in and I'm thinking to myself, why do it this (somewhat) hard(er) way?

it doesn't loop, it always prints the first item in the array (there are 18 <a>'s inside div#carousel, and 18 items in the array...)
I have an image sitting in a <td> tag, and I want the image to change every 5 seconds. I have a total of 3 images that I need to cycle, and I need it to go back to image1 after displaying image3 for 5 seconds.
I want to call the changeAd() function from the setInterval method within the startAdPAge() function because I am going to be adding more statements to the startAdPage() function, so the body onload event will call the startAdPage() function, which will in turn, call all the other functions.
I was using an if/else statement in the changeAd(), but that only changed between image1 and image2, so i am trying this array, but now it is not changing at all.

i have created an option on a website to give the possibity to the user to change the font size (smaller, bigger, reset), like the famous x3 'A' that we see in most of the websites. the code i have is based on a plugin copywrite to [URL]. now i'm facing a problem with different font size for different elements. to make the text bigger and smaller works like a charm but to reset the font size is not working so good. here is the code of the plug in the reset part:
//on clicking default font size button, font size is reset
jQuery(container + " .defaultFont").click(function(){
jQuery("#content *").css('font-size', defSize);
// coockie to rememebr the selected font size
updatefontCookie(target, defSize);
});
here is how i'm calling the function: fontSize("#container", "#content *", 8, 12, 20); container is where i have the images to make the text smaller or bigger content is the div that has the content that i want it to be changed 8 is the smallest fonr size 12 default 20 max now the thing is that i have different font sizes in the page and some of them don't have a class just the <font> ....</font> when i'm clicking the rest button then i'm getting everything with size 12 and this is what i want to change. i want to remember the current font size and set it back.

What is the correct syntax for an nested array where each array element has 3 elements, a number and two text strings?
Code:
array = ['1, Old Man, Old Man','2 Black Sheep, Black Sheep',....]
should the text strings be in double quotes("")?
Code:
array = ['1, "Old Man", "Old Man"','2 "Black Sheep", "Black Sheep"',....]
This one is throwing me off! Either I am making a stupid mistake or I'm doing it totally wrong I have an array, and I am trying to select unique values from it and assign it to another array. Here is the code:
Code:
var flag;
for (i=0;i<=pdfs.length-1;i++)
{
flag = 1;
for (j=0;j<=pdfs2.length-1;j++)
[Code]...
The problem is that the if (pdfs2[j] == pdfs[i]) statement ends up never being true. There are URL's to pdf files in the array. On the other side, if there is a much easier way to select unique values from an array, please feel free to point it out.
I'd like to reorganize the third, fourth, fifth and sixth, as well as any
elements thereafter in an array in random order:
var a = new Array('first','second','third','fourth','fifth','s ixth','etc')
In other words, the first, second and third element should remain in
position 0, 1 and 2, while the fourth, fifth and sixth, etc. should appear
in random order.
I have the following array in a chatbot
Code:
Sites=new Array("alcatraz,California in the USA","eiffel tower,Paris in France","empire state building,New York in the USA");
This piece of code searches the first part of the array and triggers the second part as a response. That all works fine. However, could it be rewritten in a way to eliminate the bailout response of "I don't know." to where it just skips over it if no match is found.I have more If statements further down the script that I want to use instead of the one bailout response. If nothing matches I have one big catchall to respond back with at the very end.
Code:
if (input.search("where is")!= -1)
{document.result.result.value = "I don't know.";
for (i=0; i<Sites.length; i++) {

I have a page with three identical listbox containing items in the same order. When an element is selected from any of the three lists, the script should search for the occurrence of the same element in other two lists and remove them on the fly from all the three lists.

this code is supposed to display and load a secondary drop down menu if a particular ID(13 OR 14) is selected from the first dropdown. it works fine for 14, but not for 13. the "test" alert displays for both 13 and 14, but the second drop down only appears when selecting ID 14. I changed my array to ('13','14','13') and then it worked for both 13 and 14. is there something i am not aware of?
