this error is killing me....

dahl1013 — Wed, 28 Sep 2011 21:37:43 GMT

for(var s = 0; s<=this.seqnum; s+=1) {
setTimeout("this.spinIt(this.sequence[s])",s*this.interval);
}

using firefox, firebug. firebug gives me the error:

's is not defined'

now to my understanding 's' is defined locally in the for() loop, but i don't understand why it is telling me it is not defined.

any help you guys can offer would be great!

oh, and first time poster, lol, if i made any mistakes.

Array calculation

Christ0 — Sun, 11 Sep 2011 11:53:20 GMT

Hi

I am trying to keep a running total of how often 2 functions return integers between 0 and 9. The test runs 100000 times and should result in 2 alert windows showing the frequency of each integer in the test.

I am trying to set up an array to hold the information - a 2 dimensional array as there are 2 functions being tested. I can't seem to get my head round performing the calculation of adding 1 to each running total for each integer.

Can anyone help??!

Timing Events

kazamm — Fri, 02 Sep 2011 16:28:15 GMT

I would like to create an online six-question behavioral assessment in which participants have three minutes to respond per question. At the moment, I have six stand-alone .html files for each of the questions, and I would like to create a javascript to loop through all six files with three minute time-intervals between each question. For example, participants should link to question one, and a timer should set for three minutes the second they start inputting their text response. When three minutes have expired, the screen should jump to question two, and the timer should re-set for three minutes the second they start inputting their text response.

Any help figuring out how to do this would be much appreciated.

Thanks in advance,
Anna

Alternative to 'document.write'

Asher — Sat, 27 Aug 2011 02:48:59 GMT

I am very new to JavaScript, however I already seem semi-stumped.

The tutorial I am using, mentions that for tutorial example purposes they use 'document.write()' however it suggests that I avoid using this as it will overwrite the whole HTML page.

I know that I can use 'document.getElementById()' for some things... however this begs my question:

When do you use 'document.write()', when do you use 'document.getElementById()' and is there also another method you use to change/write to the HTML Document using JavaScript?

Cheers,
Asher

Hi Everyone!
Being a newbie in javascripting ,I'm having trouble in creating a quite simple script.
I have to create a page where the value of a variable, described earlier , should be greater than 1.
Let me show you what i want..
[code]
var count=20
var countnow=count+1
[b][i]What to use here to show 21[/i]?[/b]
[/code]
Please tell the solution.Or a better way to do what I'm willing to do.
As I said I'm a newbie so please correct me where I'm wrong in the above code.:)

I want to limit a textbox for values upto 240 (239.99 can also be entered). It has to be formatted by inserting "," or "." in appropriate positions, It should not allow user to enter values more than 2 places of decimal and the cursor should come back for editing the value

magiciansubhajit — Mon, 18 Jul 2011 07:16:33 GMT

Hi,

I want to have a textbox in which only numeric values will be allowed whose maximum limit is 240( 230.99 should be allowed). I am unable to do that. I am able to format the value entered by placing . in proper places and also I have limited upto two decimal places. But the problem is the cursor is not moving left when I have entered a value and I am unable to limit the value upto 240. It is taking any huge number also. Please help. My code is as below :-

<html>

<head>

<script>
function isNumberKey(evt)

{

var charCode = (evt.which) ? evt.which : event.keyCode

if (charCode != 46 && charCode > 31 && (charCode < 48 || charCode > 57))

return false;

return true;

}

function format(input){

var num = input.value.replace(/\,/g,'');

if(!isNaN(num)){

if(num.indexOf('.') > -1){

num = num.split('.');

if(num[1].length > 2){

num[1] = num[1].substring(0,num[1].length-1);

} input.value = num[0]+'.'+num[1];

} else {

input.value = num.toString().split('').reverse().join('').replace(/(?=\d*\.?)(\d{3})/g,'$1,').split('').reverse().join('').replace(/^[\,]/,'') };

} else {

input.value = "";

}

}
</script>
</head>

<body>
<label for="time">Files staged in the last -</label>

<input name="time" id="time" type = "text" value="24" onkeypress="return isNumberKey(event)" onkeyup="format(this);"/> <span>hours</span>

[code]

[/code]

I'm trying to figure out how to write a function that takes the name as an input and property name as output and when the name is found using something like the above code, return the associated property name's value for that name.

eg to use it like this:
document.write getThePrice('Wooly Jumper');
document.write getTheColor('Denim Jeans');

Any ideas?

green_shores — Tue, 29 Mar 2011 02:23:45 GMT

:)i have an iframe on my webpage and i am loading appropriate page in it by clicking
appropriate button but when user logs out and at that time some page is opened
in iframe corresponding to the login pages(like "edit profile") of user then at
that moment i want to know that what page is loaded in iframe so that i close it
(if it corresponds to pages of login like "edit profile") as user logs out and if
it does not correspond to login pages then it remains as it is.For doing that i
must know that what page is loaded in iframe and compare it in " if(condition)

Make menu script relative rather than absolute

htmanning — Mon, 21 Feb 2011 22:45:49 GMT

I inherited this script for menus. It's great, except the menu positions are absolute so when I center the page they appear at the wrong place. I can't find a way to change that and I'm hoping someone here can figure it out. There is a position: absolute line in the code but changing that to relative just screws up the script.

See below.


function SwitchMenu(obj){
if(document.getElementById){
var el = document.getElementById(obj);
el.className = 'navblueon';
}
}
function SwitchMenu2(obj){
if(document.getElementById){
var el = document.getElementById(obj);
el.className = 'navblue';
}
}
function showSubNav(obj){
var subnav;
var thisobj;
if(document.getElementById){
thisobj = "document.getElementById('" + obj + "Menu')";
}
else if(document.all){
thisobj = "document.all['" + obj + "Menu']";
}
subnav = eval(thisobj);
if (subnav){
subnav.style.visibility = 'visible';	
}
}

JavaScript Input Stream

rajeevraina — Thu, 30 Dec 2010 07:43:29 GMT

I am facing a problem, where I receive a compressed (ZLIB) Input stream from a web service.

I have to read this stream on the client side.

Please advise how can I

1. Receive and read this inputstream using JavaScript/AJAX/JQUERY
2. Decompress the stream

Although I can do this using JAVA and .NET but I have to do this at the client side.

Please help.

how do I amend this code to apply to all files, not just .JPGS?

disloxic — Tue, 14 Dec 2010 08:02:51 GMT

You will see in the below code that it sets up the number of thumbnails (7) and then runs a loop to grab each image by replacing the _1.jpg, _2.jpg, etc, as each image is in a folder on the server called 4837_1.jpg, 4837_2.jpg, etc.

I need to amend this code so that it will read all types of file formats, not just .jpgs. How would you do this?

how_many_thumbnails=7

var id="ctl00_ctl00_mainslot_partmedia_nppmblock_imgPart";
var name=document.getElementById(id).src;

for (i=1;i <= how_many_thumbnails;i++) {
newsrc=name.replace(/_1.jpg/i, "_"+i+".jpg");

document.getElementById("tn"+i).src=newsrc;
}

function showpic(number) {
document.getElementById(id).src=name.replace(/_1.jpg/i, "_"+number+".jpg");
thePath=document.getElementById(id).src;
}

Need Help: Javascript Multiplication Test

leafeater — Tue, 09 Nov 2010 23:09:03 GMT

Hello,

I am trying to write a javascript page that shuffles an array of questions ( 1x1 , 1x2, 1x3 - 1x12), prints them, then has the user type in the answer, then checks them to make sure the user answer is correct.
I have looked up a lot of source code for javascript "quiz" but they all are multiple choice answers and the questions are not shuffled. This is as far as I have gotten, but now I am not sure how to take the user input text and compare them to the answer / question array to make sure to check.

var quest = new Array;
var ans = new Array;
var questprint = new Array;

quest[0] = "1 x 1 ";
quest[1] = "1 x 2 ";
quest[2] = "1 x 3 ";
quest[3] = "1 x 4 ";
quest[4] = "1 x 5 ";
quest[5] = "1 x 6 ";
quest[6] = "1 x 7 ";
quest[7] = "1 x 8 ";
quest[8] = "1 x 9 ";
quest[9] = "1 x 10 ";
quest[10] = "1 x 11 ";
quest[11] = "1 x 12 ";

questprint[0] = quest[0]+"
";
questprint[1] = quest[1]+"
";
questprint[2] = quest[2]+"
";
questprint[3] = quest[3]+"
";
questprint[4] = quest[4]+"
";
questprint[5] = quest[5]+"
";
questprint[6] = quest[6]+"
";
questprint[7] = quest[7]+"
";
questprint[8] = quest[8]+"
";
questprint[9] = quest[9]+"
";
questprint[10] = quest[10]+"
";
questprint[11] = quest[11]+"
";

var score = 0;
ans[0] = 1;
ans[1] = 2;
ans[2] = 3;
ans[3] = 4;
ans[4] = 5;
ans[5] = 6;
ans[6] = 7;
ans[7] = 8;
ans[8] = 9;
ans[9] = 10;
ans[10] = 11;
ans[11] = 12;

function shuffle() {
return (Math.round(Math.random())-.5);
}

questprint.sort(shuffle);

document.write(questprint[0]);
document.write(questprint[1]);

Javascript drop down menu compatibility issues

zeebo17 — Sat, 03 Apr 2010 15:16:57 GMT

Hi, I have found the following script for a drop down menu and I was wondering if there was a way to fix any of the following issues:

1) When you select an item on the menu, go to the new page, and then when you go back to the original page the menu item is still "open" and don't disappear until you hover over them. (So far I've only noticed this on firefox)

2) In IE7 (okay in IE8 and Firefox) when you move your mouse to the second level of the drop menu that expands to the right, it will disappear and instead jump to the drop down items of the next tab to the right.

3) In IE sometimes the menu items will drop down in two parts. The left hand side of the boxes/text and then the right hand side will follow.

Any help would be greatly appreciated!
Thanks!

[code]
var menu=function(){
var t=15,z=50,s=6,a;
function dd(n){this.n=n; this.h=[]; this.c=[]}
dd.prototype.init=function(p,c){
a=c; var w=document.getElementById(p), s=w.getElementsByTagName('ul'), l=s.length, i=0;
for(i;i var h=s[i].parentNode; this.h[i]=h; this.c[i]=s[i];
h.onmouseover=new Function(this.n+'.st('+i+',true)');
h.onmouseout=new Function(this.n+'.st('+i+')');
}
}
dd.prototype.st=function(x,f){
var c=this.c[x], h=this.h[x], p=h.getElementsByTagName('a')[0];
clearInterval(c.t); c.style.overflow='hidden';

Need URGENT help! Javascript univercity assignment

barberino — Tue, 26 Jan 2010 10:18:04 GMT

Hi guys, getting a little desperate with an assignment i have due in this week and im really stumped, javascript is quite new to me. If anyone has abit of spare time to point me in the right direction i would be greatly in your dept!

So heres there task.

I have been given some javascript code which creates a path finder script. Basicly it finds the fastest way between 2 points on a simple map. For example if i wanted 2 go between point A to point E it would find the quickest rought. There are 7 nodes A-though G. They are set out in a map liek format. They have links between them ( not every node is linked to every other) and each link has a weighting applied to it.

[a]
7 / \8
[b] - [c]
10 / 4 \
[d]
5 \ |9
[e] -2[f]
| 1
[g]
Thats what the diagram looks like exscuse the crudness. But for example going from point A to E, has several different routes. A,B,D,E; A,C,F,E; etc. The code i have been given already calculates the routes and the different weightings for each route. The lower the rating the better the route.
What i have to do is take this information and display it in a Table like form with all different routes displayed with the most affective highlighted in some way. Also i need a function which enables you to choose the to nodes (start and finish) which will change the tables results. This must all be done on the same page.

Heres the code which creates the Network, nodes and paths. This js code will be in an external js file which i have already created and linked to an html file which i have also been given and will paste below. If any1 can give me some advise on where 2 start i will love you forever :) Thanks for your time if u require some mroe information, my exsplaination of the task is quite poor plz let me know. thanks alot!
Oh and im not really looking for a entire solution just some advise on where to start and how the js code is working. Thankyou!

var NETWORK = new Array ();

var PATHS = null;

function Node(i,n,l) {
this.id = i
this.name = n;
this.links = l;
}

function Link (n,w) {
this.node = n;

HTML FILE CODE

<head>

<title> Model of a network of nodes </title>

</script>

</head>

<body>

Line 22 runs the function createNetwork() which creates a model of

a node network (see Figure 1 of assignment brief).

The function makes a series of nodes and links them together.

Each link has a weighting associated with it and is used to indicate how busy

the conection is between two nodes - the higher the weighting the

busier the connection.

The data representation of the 'network of nodes' is formally

referred to as a graph. This is a non-linear data structure commonly

used in computing.

createNetwork();

Line 35 runs the function traverseNetwork() which finds all the paths between two nodes

The function searches the network created by createNetwork() and finds all

the possible routes between the source (a node named "A") and an

target (a node named "E").

The traverseNetwork function accepts three arguments. The first two arguments are

the name of the source node and the name of the target node respectively.

The third argument is a boolean value that is either true or false. It is currently

set to false, but what happens when you set it to true?

traverseNetwork("A","E",false);

/* Line 56 writes all the paths found between the two nodes "A" and "E" to the current document.

PATHS is a global variable that stores the results of the search conducted by the function traverseNetwork(...)
The results of the search (i.e. the contents of the PATHS variable) appear as a delimited String Object thus:

available paths = A;C;D;E;22:A;C;B;E;13:A;B;E;10:A;B;C;D;E;27

The notation for the above String is as follows:

* each path is seperated by a colon ":"

* there are four paths

* nodes in a path are separated by a semi-colon ";"

* nodes is identified by its name i.e. 'A' for node A

* the first node in a path is the source node

* the penultinate node in a path is the target node

* the numerical value (last item of each path) is the total weighting

* total weighting refers to cummulative weighting associated with each link

document.write("available path = " + PATHS); //print all the paths found between node A and node E

Convert Script Help

ChiefOfGxBxL — Wed, 16 Apr 2008 20:40:44 GMT

I want help with a program with JAVASCRIPT in an HTML window. I was thinking of something like this....

-----

[ BOX 1 ] [Output BOX 1]

-----

Lets say, that in BOX 1, you put the letter 'H'. It would then put in the outbox, the letter 'G' or something....so it takes the first letter, and converts it to another.

It takes a letter / number and converts it to another preset letter / number. Was planning on a secret chat language or something...maybe could incorporate it into my flash games too.

Thank you for all your help and suggestions! I am new to this website, so thank you very much for your time! My idea is that it would be able to be put into an HTML window. I know HTML very well too. Have no idea about JS, but have been to w3schools.com. :w00t: :D :)

what is the difference between Java and JavaScript anyway?

pramoodd — Sun, 05 Apr 2009 07:34:19 GMT

major difference is how the language is presented to the end user (that's you when you're surfing). Java must be compiled into what is known as a "machine language" before it can be run on the Web. Basically what happens is after the programmer writes the Java program and checks it for errors, he or she hands the text over to another computer program that changes the text code into a smaller language. That smaller language is formatted so that it is seen by the computer as a set program with definite beginning and ending points. Nothing can be added to it and nothing can be subtracted without destroying the program.

JavaScript is text-based. You write it to an HTML document and it is run through a browser. You can alter it after it runs and run it again and again. Once the Java is compiled, it is set. Sure, you can go back to the original text and alter it, but then you need to compile again.

can any one add some more points to it plz....

Answer about .java file in module

jaypaul — Fri, 05 Jun 2009 03:41:12 GMT

Hi Friends,

I need to avoid placing all the things into one big source. So I'd like to place
the different elements into separate modules.

Ideally, I would like a separate .java file for each module: tile engine, vm and graphics.

so, I'm confused about that how I could do that. Could anybody give me any hints or tips on
how to do this ?

also i'd like to tell you that I'm working with Net Beans but Not sure if that has anything to do with it.

should i work on the jar files or any thing else ?

your answers would be helpful.

Thanks,
Paul

The effects.js is required for the accordion on the sub nav (right side).

I could really use some help here please!

HELP! with Calculation

ninjali — Tue, 12 May 2009 19:50:54 GMT

Hi people... im a bit of a noob with javascript but im learning quickly..
basically i need a calculator that adds up values when ticked.

i got this code and its all working..

Code:

<script type="text/javascript">
function calculate(f)
{
var nums = f.num;
var ntext = f.numtext;
var nitem = f.numitem;
var result = 0;
var items = '';
for(var i=0;i{
if(nums[i].checked)
{
result+=parseFloat(ntext[i].value);
items+=nitem[i].value+'';
}
}
f.answer.value=result;

//if you want to fix to 2 decimal places
//f.answer.value=Number(result).toFixed(2);

f.allitems.value=items;
}
</script>

<input type="checkbox" name="num" onclick="calculate(this.form)">
<input name="numtext" type="text" onchange="calculate(this.form)" value="59" size="3">

<input type="text" name="answer" size="10">

<textarea name="allitems" rows="10" cols="50">

but i also need it so people can input a value into textbox and have it multiply by a pre-determined number then have that add to the total...

if anyone can help it will be greatly appreciated!
seems like a fairly basic thing but just cant get my head around it.. cheers

Functions and arrays HELP

suseman — Sat, 23 May 2009 17:05:05 GMT

Not sure how to reference the actual arguments of the isAlreadySelected() fuction in the body of selectNumbers() function properly. The description of the fuctions are enclosed in /* */ and coloured green, this is what the fuctions are supposed to do. Having trouble populating an array and returning it in the selectNumbers() function . Need to use all varables in the function as it is a mock test. Any help would be much appreciated

Here goes:

/* Determines if a given ball has already been selected.

The function takes two arguments:
a whole number which is a new selection
an array which contains previous selections.

The function returns:
true if the new selection exists in the previous selections
false otherwise
*/
function isAlreadySelected(newSelection, previousSelections)
{
var prevArray = new Array(previousSelections);
parseFloat(newSelection);
if (newSelection == previousSelections)
{
document.write('already selected.', '');
return true;
}
else
{
document.write('not been selected.', '');
return false;
return newSelection;
}
}

/* The function prompts users to select numbers from a pool of balls
The function takes two arguments:
the highest number in the pool of balls
the number of balls to be selected

The user is prompted to make choices.
A check is made that a choice is not a duplicate.
The user is reprompted to make a choice if a selection has been selected already
The function returns an array of numbers selected by the user
*/
function selectNum(highNumber, numberToSelect)
{

// Alert user to the valid range of balls to be selected
window.alert('Enter numbers between 1 and ' + highNumber + '.', '');
parseFloat(numberToSelect);
var numArray = new Array(numberToSelect);
var current = 0; //not sure about this
var selectArray = new Array(current); //not sure about this

for (var index = 1; index < numberToSelect; index = index + 1)
{
numSelArray[index] = parseFloat(window.prompt('Please enter your ball selection.', ''));
while (isAlreadySelected(current, numSelArray[index]) == true)//got this incorrect
{
window.alert('Current ball has already been selected.', '');
numSelArray[index] = parseFloat(window.prompt('Please enter your ball selection.', ''));
}
selectArray[current] = numSelArray[index];
}
return selectArray(current);//and this is not right

}

IE Will Not work with AJAX Loop

VolcomMky — Wed, 13 May 2009 16:36:03 GMT

I am having some trouble in Internet Explorer

You all know that dreaded prompt message you get if a website starts slowing down your computer because of a loop?

Well I have been working on a website, got it to work perfectly in Firefox and Safari.

BUT, in Internet Explorer it refuses to work.

The website is called [URL="http://auction4pennies.net/"]Auction 4 Pennies[/URL]
It was inspired by [URL="http://www.swoopo.com"]Swoopo[/URL], a auction website with timers.

I wanted to attempt creating the website without cheating (viewing available source) and without having to purchase a $800 clone.

Right now how it is setup is:
-The page loads
-Then the page uses AJAX to retrieve the Products Page
-On the Products Page it has Current Timers and Current Highest Bidder with Amount
-After that is all loaded, it will loop every second after that, but not reloading all products, just pulling information from the database on another page (using ajax) and creating JS with the information pulled. The returned JS then is executed to reset the Timers and Highest Bidder (in case of a change)

I know there is a Fix to edit the registry on the computer, but there are problems with that.

1. The fix only works on the local machine.
2. The timers on the page take between 15 and 60 seconds to change.
3. The page is still so slow and freezes IE even tho the prompt does not display.

Are there any suggestions to fix the IE problem?

Expand a Div Vertically in sets of 100px.

Odaku128 — Sun, 17 May 2009 11:51:47 GMT

I need a script that will expand a div vertically in sets of 100px.

For example:

If the content of a div is 201px in height, i need it to have a height of 300px. Again if the content is 177px in height i need it to be 200px.

This is because i have a background-repeat: repeat-y; and the image is 100px in height. I don't want broken images to show.

I have looked almost every where and have found nothing.

Can anyone help me, please?
