I am pretty new to jQuery, so apologies for such a basic question. But, it seems to me, the DOM is a hierarchical data set, and jQuery runs up and down this set in order render many of its results.I would like to understand, therefore, what method(s) jQuery uses to traverse the DOM. Is it using some form of indexing - a radix tree maybe?Developing the thought, I am wondering if there are any caching or optimisation steps I could take to help it along.I ask because a) I am always curious about these things b) I would like to write the best code I can based upon as much information as I can get and c) I am starting to use Ajax and, it seems to me, that the sequence and timing of asynchronous requests needs to be carefully thought through. If requests to the DOM can ever conflict (logically or otherwise) with requests to a server, I would like to understand how it all works.

I would expect it to show "2" but instead it shows "0". Why?
It seems the find() method doesn't work on the newly created elements. Do traversing methods only work on elements that are actually in the document? If so, how can I traverse and manipulate freshly created elements prior to inserting them into the dom?
I'm getting some XML back from an ajax call ... it's working as expected.My problem/question is that I don't know how to traverse the XML properly using Jquery.This is what I'm getting back:
<media>
<photos>
<photo id="1" size="s">url/photo1-s.jpg</photo>[code]....
My code currently uses $(this).find("photos").each(function() to get each of the photos, and that works fine.However, the list of photos can be quite large, and I really don't need them all -I'd like to just "grab" the one or two photos I know I need based on the id and size attributes. Is this possible without going thru the entire list?
I have an iFrame on a page where I am calling .mouseup(function()) on it's document child.Once in the mouseup function, I need to refer to a specific sibling of the iFrame.Unfortunately, I cannot figure out how to traverse backwards to the iFrame element from $(this) - where $(this) is the document. I get a null set returned when I try$(this).parents().

View 5 Replies View RelatedI have an array called "Prods". Here are the different values in that array:
ProductName, HowManyCalories, ProductImage, LinkFromImage, Description, Price, BuyLink
There are a number of products. I'm just wondering how do I use "ProductName" as a product key to output its unique values?
Eg. the ProductName is "Chocolate Spread" - how do I output the "HowManyCalories" and "Product Image" only from the "Prods" array, based on the key "Chocolate Spread"?
Unfortunately, I couldn't find any way to traverse the object array in
reverse order. I'd thought there must be a way to do it with for..in
loop, but couldn't find anything yet.

I'm working on an image gallery at the moment and I'm having some trouble with the array the the images are stored in. The issue I'm having is that I can't figure out how to increase and decrease the current element in an array with the onclick event. Here's what I'm thinking so far:
var imageList = ['a','b','c','d','e'];
var position=0;
currentImage=imageList[position];
if a link with the id of "leftClick" is clicked, then position should decrease by 1 but if a link with the id of "rightClick" is clicked, then position should increase by 1 Both of these conditions should be bound to imageList.length i.e. if (position<0){position=0}; and if (position>imageList.length){position=imageList.length}; So how can I make "position" increase or decrease by clicking a link using the onclick event?
I've been stumped. I'm usually good at figuring this stuff out, but I'm completely confounded here.I have a form with tables in it to add items to a series. The rows are being added dynamically by Jquery on the click event.

$('#hybrid tr:last').after('<tr><td width="15%"><?=brands('hybrid');?><input name="clubtypes[]" value="6" type="hidden" /></td><td width="25%"><?

I am using jquery with the cookie plugin and I have multiple image buttons that can hide/show multiple elements. My question is how can I add a cookie to this code to remember whether each separate element is opened or closed?
The code,
$(document).ready(function() {
// choose text for the show/hide link - can contain HTML (e.g. an image)
var showText='<div class="expanddown"></div>';
var hideText='<div class="expandup"></div>';
// initialise the visibility check
var is_visible = false;
// append show/hide links to the element directly preceding the element with a class of "toggle"
$('.toggle').prev().append('<a href="#" class="togglelink">'+hideText+'</a>');
// capture clicks on the toggle links
$('a.togglelink').click(function() {
// switch visibility
is_visible = !is_visible;
// change the link depending on whether the element is shown or hidden
$(this).html( (!is_visible) ? hideText : showText);
// toggle the display - uncomment the next line for a basic "accordion" style
//$('.toggle').hide();$('a.toggleLink').html(showText);
$(this).parent().next('.toggle').slideToggle('fast');
// return false so any link destination is not followed
return false;
});
});
HTML,
<a class="togglelink" href="#"></a>
<div class="toggle">

I am trying to change each forms .submit function like so (below) but each submit button gets the function of the last iteration. I want each form to have a different submit function without using onclick events.

var ele = x[i].elements;[code].....
I have found a problem with <select multiple="multiple"> and .change() under ie6. The problem is ie6 fires first change event right after any other event, like selecting again, clicking mouse, pressing a key etc. It is perfectly seen on [URL]... Just click any option in demo, nothing will happen.
If i put a handler using plain DOM, i.e. $("select").get(0).onchange = function() { ... } the problem dissapears. So, it's definitely a bug with jquery. JQuery version 1.4.2.
I'm trying to search for the correct code to make my form work. I have 3 select boxes - one with 2 options, one with 8 options, and the last with 2 options... All of this adds up to 32 different url paths. Can anyone tell me how to get this done?This is what I have so far: (and yea, I know I suck... I honestly have absolutely NO clue)

This is my first post to this forum. When a button in parent window is clicked multiple times, more than one popup window is opened. This problem is occurring in linux firefox and mozilla browsers. In windows the code is working fine. Is there any option in window.open() method to open a popup window once. s there any known issue regarding this case?. Need a workaround to fix this issue.

Does anyone know of a Javascript slider that can function like Adobe's gradient creator?I'm not actually making gradients, I just need similar slider capabilities.I have a defined date range, let's say it's January 1 to Januaray 31. I want to make a slider that allows my user to split this date range into multiple ranges. So one person can do:
Jan 1 to Jan 5, Jan 6 to Jan 12, Jan 13 to Jan 31 Another person can do: Jan 1 to Jan 21, Jan 22 to Jan 31. How many regions they create doesn't matter to me. The goal is to pull it off with a Javascript slider that works similar to Adobe's gradient creator. Handle's can be added by clicking and removed by pulling it away from the slider. Handle's can also slide around fairly liberally.
I am familiar with the user built addEvent function used to load multiple functions in the window.onload property. However, I am curious as to the best way to do this across multiple JavaScript files. I thought I had seen somewhere code similar to the addEvent function was native to JavaScript now but I can't seem to find that anywhere.
Just to clarify, suppose I have 3 JavaScript files:
Code:
function foo() {
// do something here
}
fileB
[Code]....
note that it is not feasible to combine those functions into one file as they aren't always loaded together. What's the best way to load them all as a window.load?
