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:
ajrdvb"fomfkswk'mbncrfu
ajrdvb'fomfkswkmbncrfu

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 looked around for a solution but could not find one. I am trying to find combinations of numbers that can add up to a total. The numbers available and the total are different each time.
For example, I have an array that contains the following numbers:
[16,12,8,6,4,2]
I want to find the combinations that add up to 140, like this:

I need to know how I would go about making it so that when people select an option like men it populates a different set of dropdown options in the second dropdown (and a different set of options if I select women, etc...), and then I can select an option like Hair Care Products and have it swap out the image in a div to show mens hair care products. I have code to do this for just one dropdown, but I don't know how to make it work with two dropdowns that populate different info based on the selection of the first dropdown.
<label>
<select name="menu" id="menu">
<option value="Men" selected="selected">Men</option>
<option value="Women">Women</option>
</select>
</label></td>

The code I will am including is far from finished, but some of what I do have works (the "submit" code does not work yet). I am able to prevent certain kinds of input including Shift-Ins pasting, but Ctrl-v pasting still works (and I do not want it to). Could you please tell/show me what code needs to be entered to my existing functions, or what new function I need to create (and call from my existing functions) to eliminate any kind of CtrlKey input?

I am having trouble writing this javascript for my work, normally I would do this in ASP or PHP, but the environment I am working with will only allow javascript for dynamic function.
The form has two different select boxes and based on your options selected for select box #1 and select box #2, the hidden input field "redirect" (which is currently empty) would then populate dynamically with the URL associated with that combination mentioned below. The hidden redirect input field (now containing dyanmically generated data) would then pass the new value via HTTP_POST to .net script that will handle the redirect processing step fed to it. code...
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:
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'm calling a recursive function, and I want to display an alert after its done running, the thing the function is "done" after goes through it once.Here's the coles notes version....

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.

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 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.

I need a simple, quick and efficient way to logically branch if I find a string is contained in another string in jquery Most other languages this can be resolved in one or two lines and it would be readable.

I need help with substring or trim function in javascript. Find below my code. Selection holds the value Select State, and length of the string is 14. I need to equate the Selection value to string "Select State" and execute alert message.
function selected_item() {

alert("Select the State");[code]....
I tried this:
var state=Selection.substring(0,11); and then string would be equated to state variable. But it is not working.
