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 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 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?
I use in my javascript the "document.getElementById" code.
This code works as it should in Firefox, but in IE I get the following error:

i have given the hyperlink with javaascript to the iamge button as <A href="javascript: submitform()"><img alt="test" src="Images/test.png" /></A>

I am using the following code to show/hide part of an html page. It
works in Netscape and Firefox but dies in IE: "Error: document.layers
is null or not an object"....
document.getElementById (which + "sel").value = document.getElementById (which + "sel" ).value + "'" + document.getElementById (itemtocheck+i).parentElement.title + "',";
Error: document.getElementById(itemtocheck + i).parentElement is undefined
Why the following code has the error: 'document.mainform.unknownHw' is null or not an object?
View 2 Replies View RelatedI 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 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.
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');
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've been trying for hours and I can't figure out why IE6 is throwing an derror on the following line of code.
Code:
var parts = rgbString.match(/^rgb((d+),s*(d+),s*(d+))$/); This is the function:
Code:
function rgbToHex(rgbString)
{
var parts = rgbString.match(/^rgb((d+),s*(d+),s*(d+))$/);[code]....
And this is the error:'null' is null or not an object
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:
Code:
Site - [URL] Location of js and css - [URL] The jCarousel works great in all other browsers, but in IE, when you get to the end of the jCarousel it gives the "Error: 'url' is null or not an object" pop up and it won't let me use the left arrow buttons to go back.

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]

I would like to know if is better to use document.forms to detect forms
or getElementById.
