Recursive Function
Jul 20, 2005
I'm having trouble with a recursive function.
The function is supposed to identify nested folders in a hierarchical
folder structure.
The function "searchForFolders()" is supposed to traverse sibling
nodes in each iteration, and for each sibling node, it calls itself
again, to see if there are child nodes of the current sibling.
The code below contains the function in question. For simplicity's
sake, I have replaced the images with text characters. It doesn't
look as good, but you should be able to see how the nesting works.
When you click on a "Folder", you will get debug text on the RHS of
the screen.
You will see there is an XML hierarchy. That is parsed by another
function in the page to write out the hierarchy. That is working
fine. The only functions that I am having trouble with are
"searchForFolders()" and "hideShowFolder()". Code:

I am coding an AJAX DHTML whatever application and I was fed up with
always typing a lot of appendChild() functions.
I created a custom one called append_children() and wanted to share it
if anyone need such a function.
function append_children() {
var a = append_children.arguments;
for ( var i = a.length - 1; i > 0 ; i-- ) {
try {
a[i-1].appendChild(a[i]);
} catch(e) {
for ( var j = 0; j < a[i].length; j++ ) {
append_children(a[i-1], a[i][j]);
}}}}

Here's the function:
function getParentElementByTagName(child, TagName){
var cn;
if (child.parentElement){
cn = child.parentElement;
if (child.parentElement.tagName == TagName){
return cn;
}else{
getParentElementByTagName(child.parentElement, TagName);
}}}
although it finds the element, the function returns null ( on the line
'return cn', cn is not null though). Is my algorithm wrong ?

I have written a function that works but it is recursive so ends up blowing the browser stack.I have seen a few examples of converting recursive functions to use a local stack but cannot convert my own function.I have a recursive function that is using the return values to build a result.

I've got following function:
[Code]....
I would like to run this in recursive mode, and I'm starting the function with:
$(function(){
$.bubbles();
}
The problem is, that function works only one (and a half) time. Console shows: start callback start I have not idea what is a problem. Function needs to be run constantly.

I'm trying to return all the permutations of a given string, so I wrote the following recursive function:
The problem is, I'm not getting all the permutations, and I don't know why.
For example, if string="bindle", the output I get is:
And then the function stops.

I have been looking at this code for two evenings now, and rewrote it 4 times already. It started out as jQuery code and now it's just concatenating strings together.
What I'm trying to do: Build a menu/outline using unordered lists from a multidimensional array.
What is happening: Inside the buildMenuHTML function, if I call buildMenuHTML, the for loop only happens once (i.e. only for 'i' having a value of '0'.) If I comment out the call to itself, it goes through the for loop all 3 times, but obviously the submenus are not created.
Here is the test object:
test = [
{
"name" : "Menu 1",
"url" : "menu1.html",
"submenu" : [
[Code].....
'Menu 2' and 'Menu 3' don't show up! I'm sure it's something small that I'm overlooking.

Is there any way once I've done something like:
var newFields = document.getElementById('myDiv').cloneNode(true);
var newField = newFields.childNodes;
To recursively walk through and change the names of every form element found? Similar to:
var theName = newField[i].name;
if (theName) newField[i].name = theName + "[" + fCounter + "]";
I need the counters because my users can add multiple new fields to the form, and perhaps delete one out of order. (They add 3 blocks of fields and delete the 2nd one.) For formating purposes I have some <div>s in my cloned node and I can't get to the form elements inside these divs. Here's some simplified markup to illustrate what I have: Code:

I have a string "ajrdvbfomfkswkmbncrfu" where the 3 letters b,k and f can be in three forms: b,b',b" and k,k',k" and f,f',f".I want to find ALL the possible string combinations.Is there a simple way to do that in JavaScript? (probably with several for loops)
Ex: Hera are 5 combinations:

This recursive menu is built with ColdFusion and then Javascript is used to turn the style display on or off. The problem I'm running into is this. The menu currently has 4 levels. MicrosoftMicrosoft TechnicalDynamicSystem CenterWindows ServerHyper V The menu is collapsed and as you mouse over an item that has child elements it expands. The problem happening now is the menu loads expanded only for the 'Microsoft' element. (note this is the only menu tree that has 4 levels).
So it looks like this when loaded initially. MicrosoftMicrosoft TechnicalDynamicSystem CenterWindows Server When you mouseover 'Microsoft' it then expands the 'Hyper V' menu item underneathe Windows Server. Mousing over 'Microsoft' should open 'Microsoft Technical', etc... I imagine the code doesn't support that many levels because if 'Hyper V' is moved out and put under 'Microsoft Technical' as a child the menu works fine.

I'm using the Google AJAX APIs, but some reason google.load works when run through normal javascript, but if I call the method from my jquery ready function it doesn't work. Code and output is below
page.html
<script type="text/javascript">
loadGoogleStuff();
function loaded() {
console.debug("in loaded function");
}
[Code]...
window.loadFirebugConsole is not a function If I comment out line 3 in code.js, the console debug runs okay, so the ready function is running okay. Even though there's a reference to Firebug, the same error occurs in Safari too. Nothing on the page loads.

I'm using jQuery 1.4 to hide a div (#cartPop) when the "close" link inside of it (#cartPop a) is clicked. Since I'm using animate() to fade the div out (opacity), I also have to use hide() to get rid of the div once it has faded out (otherwise the invisible div, which is on a higher z-index, blocks the elements on a lower z-index).
Code:
The problem is that the hide() function calls immediately without waiting for the animate() function to run. Even if I append a delay() function before hide() like so:
Code:
...it still doesn't wait.

I am trying to minimize the amount of script that I use on my website. I have sections of each page; each section has the same basic layout. The divs and images that I want to make appear and disappear all have nearly identical ids, the only difference is the number at the end of the id.Is there a way to get one script to automatically detect which id number has been clicked and then show all elements with the same number at the end of the id? I would also like it to hide the elements in the hide function below (basically they are the elements that do not share the same id number).I currently have everything working the way I want it to using multiple functions like the one below but I woul
$("#2thumbNail2 , #ledBar").click(function () {
$("#type201 , #type203 , #type204").hide();
$("#image201 , #image203 , #image204").fadeOut("slow");
[code]....
