Tree Navigation

Apr 9, 2006

I'm trying to do something rather simple. I want to find the only
<form> inside of a <div> named "newreplyform". Here's my code:

var nrf = document.getElementById('newreplyform');
var form = nrf.getElementsByTag("form")[0];

code as quickly as possible. Am I doing something completely misguided?

JQuery :: Looking For Expand / Collapse Tree Directory Navigation?

Jul 25, 2009

I'm looking for an expanding/collapsing tree directory type of navigation and was wondering if someone knows of a good one that's out there and available.

What I'm specifically looking for is one that is triggered on the click of a *graphic* that toggles the show/hide. Each text nav item should be hyperlinkable to it's own link/page. So for example (the + and - are the collapse/expand graphics, the dot leader is for some formatting) [code]...

I'm trying to implement a minimal navigation bar using jQuery's toggleClass() function but can't seem to get it working.

It's the .img_selector div at the bottom of the page:[url]

I want to toggle the 'active' class for each <a> when it's selected, to indicate which image is showing, so after calling jQuery, in the <head> I've got:

Then the links, which also include the showPic function:

DOM Tree?

Mar 23, 2006

What does it mean to "walk the DOM tree"? How do you use it?

I hear programmers using this term loosely and I'm not sure what it means. I understand that DOM means Document Object Module and that they are referencing the additional elements whithin (X)HTML.

Dom Tree

Oct 12, 2007

I've got a bit of ajax code that loads some content into a div. What I want to do is alter the href and action of all links and forms loaded into the div.

I thought the cleanest way to do this would have been to recursively look at all the child nodes of the div, and alter the href/action of any link or form elements that I encounter, is this do-able?

Remove P Tag From DOM Tree

May 19, 2011

I need to remove the element with the class "group" on it from the DOM tree with javascript (eventually with prototype, but no other library). I don't only want to hide that paragraph, but remove it entirely from the DOM tree. My solution to use getElementsByClassName does not work.

function hidegroup() {
var group= document.getElementsByTagName("p")
.getElementsByClassName("group"); = 'none';

<div id="poems">
<div class="poem" id="d1">
<p class="group">
<a href="#">To the top of the page</a>

Traversing XML Tree - Two Variables?

Aug 14, 2011

I have the following XML:
<MemberProvider name="myName">
<Name>Beacon Lighting</Name>
<Address>219 21 William Street, Cannington WA 6107</Address>
<Phone>08 9356 6422</Phone>
<savingText>Members get 10 off RRP</savingText>
<disclaimer>Also save 10 off grid connected solar power systems</disclaimer>
</Marker> ......

Now in my Javascript, I have
var xmlrows = xmlDoc.documentElement.getElementsByTagName("Marker");
var xmlGroups = xmlDoc.documentElement.getElementsByTagName("MemberProvider");
//for the number of Member Providers listed
for (var i = 0; i < xmlrows.length; i++) {
var xmlrow = xmlrows[i];
var singleGroup = xmlGroups[i];
var xmlcellLongitude = xmlrow.getElementsByTagName("Longitude")[0];
var xmlcellLatitude = xmlrow.getElementsByTagName("Latitude")[0];
var point = new GLatLng(parseFloat(, parseFloat(;
//get the name
var name = singleGroup.getElementsByTagName("MemberProvider")[0].getAttribute("name");

Why do I have two variables loading the xml doc? The first appears to work, but the second (xmlGroups) does not. Every time I try and get the Name attribute from the MemberProvider node, it throws getElementsByTagName("MemberProvider")[0].getAttribute("name"); is null or not an object.

Array, Hashtable Or Binary Tree?

Dec 13, 2005

I am looking for the best performing solution for modifying and
iterating an object graph in JavaScript. I have outlined below a
simplified example of the object model and examples of how I will be
using this graph.

Object model:

Two objects, [BadApples] and [GoodApples] each contains a collection of
[Apple] items (500 max). [Apple] simply has an ID and a name.


A quick way of determining whether a certain apple exists in either
[GoodApples] or [BadApples] (by ID).

A quick way of iterating through [GoodApples] and [BadApples] in order
to update the web page.

A way of moving a certain [Apple] (by ID) between [GoodApples] and

I currently have this implemented using arrays, but iterating these
arrays is expensive. Is there an implementation of a binary-tree for
JavaScript? The real-world application may contain many hundreds of
nodes, and performance is crucial.

Tree Structure Not Working Properly

Dec 16, 2010

Let me explain the scenario. I have a main html (e.g. main.html) page, which includes a link to inner.html page. Clicking this link will load the inner page, containing a tree structure. [URL] The loading method is such that only the body content from inner page is loaded to the main page, without refreshing the main page.I believe this method is called partial rendering of pages.
