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.
View 2 RepliesI'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'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 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 ?
Here's a simplified version of the function that's giving me trouble:
Code:
function saveArray(w){
var arr="['z',[";

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

but when I try I receive the error countDown is not defined.
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 am pretty new at javascript OOP.
I have a javascript file that has plenty of javascript functions, variables, arrays, etc.
I need to convert this into an object.

I am trying to convert binary to decimal with this function but it doesn't convert to decimal, but does decimal to binary.
Code:
function bin2dec() {
var x = document.getElementById("bin").value;
if ((/[^0-1]/g.test(x)) || x == "") {
alert ("You must enter an integer binary number!");
document.getElementById("bin").value = "";
document.getElementById("bin").focus();
return false;
}
x = parseInt(x);
var dec = x.toString(10);
var hex = x.toString(16).toUpperCase();
var octal = x.toString(8);
var figs = "The decimal representation of " + x + " is " + dec + "<br>";
figs = figs + "The hexadecimal representation of " + x + " is " + hex + "<br>";
figs = figs + "The octal representation of " + x + " is " + octal + "<br>";
document.getElementById("result").innerHTML = figs;
}
I'm new to jQuery but pretty familiar with JavaScript. I would like to convert the code below to a function that can be used like "$("#member-feedback li ").rotateElements()". I've looked at some examples, but I'm not sure where to start.

I have a string with javascript linebreaks with /n. I want to make a function that will make a text only ordered list (text within a text area... i.e. I don't want to us ol and li)
For example,
Spot1
Spot2
Spot3
would be converted to
A) Spot 1 -
B) Spot 2 -
C) Spot 3 -
So far I think I need to use an array, and replace...
Code:
function AddLabels(element_id) {
x=document.getElementById(element_id).value;
countlinebreaksstr=x
try {
return((countlinebreaksstr.match(/[^
]*
[^
]*/gi).length));
} catch(e) {
return 0;
}
var myArray = [A,B,C,D,E,F,G,H];
var i=0;
for (i=0;i<=10;i++)
{
}
I'm trying to add a unix timestamp into an exisiting function, but am uncertain how you add the variable. I searched the boards here, and came across this example to convert a date to unix in javascript. var date3 = new Date(Date.parse("21 May 2009 10:03:20")); And I'm trying to add it to this: flashobj3.addVariable ("targetTime", $date3);
View 2 Replies View RelatedIs 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 discovered this really great jQuery plugin which adds a scroll to top link to every page (implemented through my CMS) - http://blog.ph-creative.com/post/jQu...ll-to-Top.aspxIn Firefox its fine but in IE after going through a few pages I start to get an alert box which says "Stack overflow at line: 13". I understand that this may be caused by an infinite loop but being a JS novice I'm kinda lost as to where to start.
View 1 Replies View RelatedI 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)

When loading my web page I'm getting this error"stack overflow at line 0"What can be the reason for that? Is it related to the images I'm using in my site?
View 10 Replies View RelatedIs there any way to prevent this error, flush some memory maybe?
Is it caused by logical coding error? (script runs error free except this)

I'm testing out the Opera browser to see what to expect from the upcomming Wii browser. But whenever I try to play this javascript game (www.kirl.nl/javaSnake.html), I get the following error:
"ECMAScript interpreter stack overflow.
Script terminated."
How does Opera handle Javascript diffrently, is there possibly a site wich lists the diffrences between the browsers and how they handle code?
Any specific Opera quirks you know of?
I'm look to create a kind on instruction manual where the user can slide through pages. Rather than using an image slider, which scroll's through the images (or content), I want to stack the pages on top of each other.1. Click NEXT and Page 1 slides into view.2. Click NEXT again, and Page 2 slides out on top of Page 13. Click PREV and page 2 slides back, out of viewI started a fiddle here, showing the slide of page 1. But I'll need a way to count the pages, and for the NEXT and PREV links to know which pages to slide.
View 3 Replies View RelatedDoes anyone know of a hacked up JS patch for Error.prototype.stack or a getStack functionality for IE and Safari?
Does Opera have Error.prototype.stack?
Maybe something like:
Code:
Error.getStack = function getStack( error ) {
if( error.stack ) return error.stack;
// look up the call chain...
var fakeStack = [ ];
for( var caller = arguments.callee.caller;
caller != null; caller = callee.caller ) {
fakeStack.push( caller );
}
return fakeStack;
};
This is just typed in. I need tested library code that I can rely on.
stack overflow at line 1797.i have this error when i run my java script calendar.
