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....
Code:
function yay(n){
n = n-1;
if(n=0){
[code]....
I don't want it to show the alert until its done all of it's recursive splendor.
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 seen many script and pages on the Net, that show a code like this as correct

I have done some searching on the discussions here and have found info on waiting for fadeins, etc. to finish and then calling another function. However, I am needing something a little different. I am needing for function 1 to process and then call over to function 2 once it's finished. Here is my code:

I have tried to write a wait function but it seems like it will not brake the while loop. I tried two different solutions. Can anyone tell me what I am doing wrong, and come with another suggestion? If I call the function like this: wait(500); it should wait 500ms right?
function wait(time) {
while(1){
setTimeout("break;",time);
}
}
function wait(time) {
var flag=0;
while(flag=0){
setTimeout("flag=1;",time);
}
}
I have a scenario where the user can click a delete button to remove a dynamic element from the page. Whent he button is clicked I want the element to slide up and then be removed from the DOM. I can't make this work however. I can either slide it up or remove it. how to force the remove function to wait until the animation
is complete?
function test()
{
first();
second();

i have this type ofsituationin my code, now many time function three is called before first and second complete execution.i want third to wait until first and second finish execution, dont want to use delay
I'm using the submit and ajax functions to check a form. When the form is submitted the submit event executes and within that event the data (a code the user has to fill in) is sent to the server to check if it's correct. If it is correct, the submit event supposes to return true (so the form submits), if it's incorrect the submit event supposes to return false (so submitting the form cancels).
Here's my code that should do this:
$(function(){
var submit = false;
$('#login').submit(function(){
$('span.error').fadeOut('slow');
$.ajax({
url: '/ajax/login',
type: 'POST',
data: 'code=' + $('#code').val(),
success: function(response){
if (response != ''){
$('span.error').fadeIn('slow').text(response);
submit = false;
}else{
submit = true;
}}})
return submit;
})});
But here's the problem: While jQuery does the ajax request, the script continues. So it will return false - even if the code is validated - because the var submit has been set to false at line 4. When I submit the form again, the form is validated because 'submit' is true (but that's set to true the first time). How can I ensure the submit function waits for the ajax request to finish?
Any way to wait until it is fully loaded

$(document).ready(function(){

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:
ajrdvb"fomfkswk'mbncrfu
ajrdvb'fomfkswkmbncrfu

document.getElementById("ss2").innerHTML = "Loading...";

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 trying to write some code to show a little div (with an image
is sayng is loading...) that is showed when the page is loading...
the events I can use are onbeforeunload, onunload and onload but with
that the code does not work!
are there a solution to show a little div while the page is loading
and then make it to disappear when the page is loaded?
I am writing a chrome extension.In this extension i append a img tag to the dom. Then i read the width and the height of the picture to adjust it to the viewport size. The problem is that when i read the dimensions right after adding the img tag i get zero with and height. I could fix that if i make a setTimeout between adding img and read size.

Now what i want to do is: i have a callajax() function. with in this function i will call do_login() function. this do_login() handles an ajaxrequest and returns the responsetext.
Now i want to do some validation on this responsetext(in case of onsuccess). so i am trying to return value to callajax() function for onSuccess case in ajaxrequest.submit();
That is(onsuccess response) supposed to be some string( but not true or false). but i am always getting false in ajaxcall() function. i know the do_login() function is returning false before ajaxrequest completes
So i want to stop this and make do_login wait until ajaxrequest completes and then i want to return it's response to callajax() function.
