For some reason getElementById continues to tell me that it had grabbed a null value despite any value I input. I am using firefox 3.6.8. Am I doing something wrong here?

I keep getting an error stating "getElementById("ballElement") is null, but I have a div with that exact id. I have looked at the JS script before that line, but found no errors there either. Please take a minute to see if you find something.

Basically i'm trying to draw a box over an image which
is turning out to be a nightmare. The problem i'm getting at the moment
is that i'm creating a line with <div which works when it's not hidden
but I need to be able to make it hidden so I can use layers to show all
when it finished drawing to make it smoother. This is how some other
scripts are doing it that i've seen. So i've got it drawing a line and I
need getElementById to pick out the layer but it's only picking out NULL
with the one i've got enabled below. I've tried the others but they just
come out as errors. I need to get top2 which is the <div line to show
itself but I can't seem to reference it by getElementById. I use linux
mozilla so i need it working in mozilla as well as windows that's why
i'm using getElementById. My code is below any ideas anyone?
Suppose I have the following inside a function:Code JavaScript:document.getElementById('display_content').innerHTML = "hello";The above works.However, when I define it like the following it says display_content is null on firefox error console.
Code JavaScript:
var display_content = document.getElementById('display_content');

This function was working in Safari but not in Firefox. I was referencing a couple of elements using the forms[] array instead of getElementById(). I changed those refernces to use getElementById() and now the calculateTotals function does not work in Safari or Firefox.
So I did an alert box to see ucell and it was null. I tried two more alert boxes for the id I was passing to getElementById and for the id of the actual element on the page (which was also created dynamically). They were both identical. The element is created in the onload event, and I am not calling the calculateTotals function until there is onchange event on a text box. So it is not that the element has not been created yet. . Code:
Why this simple script is not working. Trying to use getElementById() but Firebug says the ID is null. I've tried troubleshooting by accessing other ID's but they all come back 'null'. Trying to add 2 classes based on an ID:
<script>
pageId = 1;
if(pageId == 1) {
//alert('This is page' + pageId);
document.getElementById('arta').setAttribute("class", "menu-on menu-a");
}
<./script>
An online example is here: [URL]. I also tried accessing the id like below but got the same result:
document.arta.setAttribute('class', 'menu-on menu-a');
Here's my code :
1: function myFunction(myLink, base) {
2: var myCheckBox;
3: var idx;

when I view source of the page , I see the values of sng_ids_{index} hidden parameters set correctly but I get this javascript error :
Error: document.getElementById("sng_ids_"+i.toString()) is null
This seemed like it should be so simple. It works fine in Firefox, but not in IE. The goal is to disable the form's Submit button, until the question is answered. (The alert is for troubleshooting.)
Code:
Obviously, this HTML is in a form:

I modified a little a script from dynamicdrive.com (Animated Collapsible DIV v2.01[URL]... It works well, but something is wrong. When you click on the button image a javascript error popup appears:
An error exists inside your "ontoggle" function:
TypeError: document.getElementById(divobj.id + "_info-toggle") is null
Aborting execution of function.
You can see it in: http://cineout.es/div_test/divs_test2.html
I wrote the simple code in javascript but it dosent work its
document.getElementById("Label1").innerText = "Change";
but it gives an error : "'document.getElementById(...)'is null or not an object "
I'm getting the following problem. The reason is that the object appears through AJAX. But if I choose it NOT to appear it gives this problem. How can I avoid this? I put an if statement inline
Code:
if(document.getElementById('vsbtitle_1').value!=null){
thisurlext+='&btitle1='+document.getElementById('vsbtitle_1').value;
}
Error: document.getElementById("vsbtitle_1") is null

I have a html file and a separate javascript file.
The html file contains: <input type="reset" id = "resetButton" />
I want a message to pop up if the reset button is pressed.
So in the js file I have: document.getElementById("resetButton").onclick = doAlert;
doAlert is a function that simply does: alert("Do you want to reset?");
I know my separate js file is linked correctly because if I just put in alert("hello"); in the js file then it works. But if I use the document.getElementById thing in the js file, then there is an error. The error, according to the error console, says that "resetButton" is null.
I have some javascript to test for screen resolution and if it's of size x it loads one flash file and if it's larger it loads a different flash file. The code is not in a function so it should run when the page loads. The test for screen resolution is working but firefox error console says document.getElementById("embed1") is null.I thought it might just not agree with my using innerHTML to add a flash file but when I just did
Code:
window.alert(document.getElementById("embed1").innerHTML); it still had the same error.
does javascript outside of a function run before some elements are loaded? I see no reason for this error.
Code:
<script type="text/JavaScript">
var screenwidth = screen.width;
if (screenwidth <= 1024) {[code].....
I'm performing some validation functions on a form I've created.For the phone number, I have 3 text boxes lined up next to one another. The first is for the country code, the second is for area code and the third is for the remainder of the phone number.I have used the following in order to detect whether the input value isNaN.
Code:
input = document.getElementById("phone1");
if (isNaN(input.value)) {
errorText += "[code]...
As I have three text boxes for the phone number, can I group them within this one statement? So, ...getElementById("phone1, phone2, phone3"); ?If not, what would you recommend?
I have a draggable marker on my page that sets the value of a javascript variable when the marker is released.I want to submit this value to store it in a database however I cannot figure out how to pass this javascript variable as a hidden form field.Here is my code. I suspect this is completelyhow to make this "lat" value available to me after the form has been submitted.
Code:
<form name="myform" method="post" action="" >
<input type="hidden" name="lat" id="lat"

I want to restrict getElementById to search children of a specific element instead of searching the entire document, in the same way that I can do getElementsByTagName using a specific element as the parent.
In this particular instance the parent is a table and the elements I'm interested in are all TDs, so I did the basic getElementsByTagName('TD') off the table and looped through this array checking the IDs. However, I'm suspecting that the browser can do getElementById faster than I can do a loop in javascript. Is there a neater way to do this? For now, I'll settle for IE-only solutions, though it would be nice to have things work in generic browsers.
I did find the javascript twice in my code, once in the header and once here, so i removed it from the header. I also changed to src to the full url. But i am still getting this and i dont know why. the file is located in the root directory. found a solution. basically Internet Explorer is crappy and doesnt like the setAttribute property so had to change the onchange handler by directly changing the attrbute for the object like so.object.onchange = function() {}i have no idea what they means, does that mean i need to change swfobject.js or does that mean i have to change my xml request. and if it is the swfobject i have no clue what they mean or what lines

And this is the error:'null' is null or not an object
I put a long script but the problem is small.
var book1 = bobj1.value;
var chapter1 = cobj1.value;
var verse1 = vobj1.value;
var book2 = bobj2.value;
var chapter2 = cobj2.value;
var verse2 = vobj2.value;
[Code].....
I don't know if this is written properly: if(bcv[a]!= ""){ The reason this is happening is because the error shows: Error: cobj1 is null Source File: [URL]
My code is in the attachment alex.txt.When i press the button for first time it gives me error: 'null' is null or not an object. But when i press it again or refresh the page and press the button it gives me the result that i expect.When i change the var pdbfile1,2,3 values(for example with 2x4n;3gis;1crn) and press the button again there is the error again and i have to refresh the page again.

I am trying to alter css using javascript as well as use the innerHTML
function. I have pasted below 3 forms that access getElementById in
slightly different ways (I wanted to rule out that it was the method.)
All 3 work fine on IE but only work momentarily on Firefox. For
example, one form has text that changes from red to black when the user
clicks the button. In IE it changes. In Firefox it changes for a
split second then goes back to black. Code:
