GetElementByID Error...
Jul 20, 2005
I have this annoying problem with netscape...
I'm trying to access a form value by using getElementByID and in NS i
end up with a null reference.
The following HTML is the form component that gives me headache:
<form name='task' ...>
....
<select name='prioritySelect' class='selectwidth'>
<option value=''>Choose one</option>
<option value=Ƈ'>Critical</option>
<option value=ƈ'>High</option>
<option value=Ɖ'>Medium</option>
<option value=Ɗ'>Low</option>
</select>
....
</form>
And the related javascript code:
if(document.getElementById("prioritySelect").disabled == false)
{ ... }
When digging into this I can get the desired information by using
document.task.prioritySelect, but that should not be necessary, right?
I hope that anyone knows how to deal with this problem..

I have a javascript function which uses the method
document.getElementById.
I'm using it to decide whether a checkbox has been ticked or not. This
decision is encoded in an if statement with the condtion being
if (document.getElementById(checkboxtoupdate).value ==1)
/* The Code */
function set(object)
{
var checkboxtoupdate = object.value;
if (document.getElementById(checkboxtoupdate).value ==1)
document.getElementById(checkboxtoupdate).value = 0;
else
document.getElementById(checkboxtoupdate).value = 1;
}
The "object" accesses a html tag which has an value attribute e.g
value="7400"
However Netscape Navigator 7.1 does not seem to recognise
"document.getElementById(checkboxtoupdate).value"
and reports an error that
document.getElementById(checkboxtoupdate).value has no properties.
But Internet Explorer has no problem with this at all.
Is there another way to do this so as to be recognised by Netscape 7.1?

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.

I am normally a VB programmer but now I need get a page to work in Mozilla so I am attempting to convert my VBScript to Javascript. The code in VBScript worked fine. The Javascript version is failing. I see this error on Load: Unexpected Token in Attribute Selector: '!'
If I leave the radio buttons alone, input a non-numeric character in the first field for Length and then tab, I get my alert but the value doesn't change to zero. In the error console, I see the following error: document.getElementById(MyField) is null
I found a couple of ideas to try via web search such as document.getElementById(MyField+'') but get same error. [code]...

My code:
function run() {
for(var k = 0; k < newPhotos.length; k++)
{[code]....
I get an error on this line Quotedocument.getElementById(imageId).style.backgroundImage = "url(" + newPhotos[k] + ")";
the error is: QuoteObject Required
I'm just not sure what object they are talking about. This piece of code basically goes through and assigns x amount of divs a background image.

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'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've got what should be a simple assignment of either an element value
or a default string to a variable, but when the element doesn't exist I
get an "Object required" error rather than an assignment of the default
value.
I originally used the simple statement:
var v = document.getElementById('foo').value ||
parent.document.getElementById('foo').value ||
'unknown'
document.writeln(v);
This caused the "Object required" error if there was no element, so I
added some error checking:
var v = (document.getElementById)
? document.getElementById('foo').value
: (parent.document.getElementById)
? parent.document.getElementById('foo').value
: 'unknown'
document.writeln(v);
Unfortunately, this still results in an "Object required" error when
the element is not present in the document or its parent.

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'm new to jQuery and the validation plugin, I just wondered if it is possible to get the error messages to be shown in an error summary section instead of inline?

I am developing a web page . For this i am using Javascript embedded in html. In the application ,the user can input data via interfaces in the page which is chosen and read from a master xml file , the chosen data then needs to be stored and saved in a xml file.I have designed the web page in FrontPage.
Now the problem i face is while trying to save the output xml file i get error Permission Denied , error code 0 . This happens when i try to open the page in browser IE 6.0 SP2.I am using DOM parser methods for doing the xml manipulations/savings etc.urprisingly this works in another machine.Also can i use the all of the same javascript code if i want to run it in an IIS. Do i have to do some changes to make it server side javascript code.

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:

I have this problem and when I came looking for help, I checked out the other thread like this but I couldn't get it to work. Here is the function -
PHP Code:
function newForm(focus, field)
{
if ( focus == 'no' )
{
if ( document.getElementById(field).innerText == '' )
{
document.getElementById(field).innerText = '____________'
}
}
if ( focus == 'yes' )
{
if ( document.getElementById(field).innerText == '____________' )
{
document.getElementById(field).innerText = ''
}
}
}
and here is the form -
PHP Code:
<b>Field 1:</b> <input type='text' name='field1' class='textbox' value='____________' onFocus="newForm('yes', 'field1')" onFocusOut="newForm('no', 'field1')" /><br /><br />
<b>Field 2:</b> <input type='text' name='field2' class='textbox' value='____________' onFocus="document.form.field2.innerText=''" onFocusOut="document.form.field2.innerText='____________'" /><br /><br />
field1 uses the function but field2 uses just onFocus and onFocusOut but as you can see, it won't work.

Works fine in FF, Safari . . . but not with IE. The error is "Object doesn't support this property or method".I have narrowed it down to this line (and a few like it)name = escape(document.getElementById('name').value);The escape() is not the issue, same with or without.I am trying to capture the text value from the field with id='name'. I have found discussions about this problem with IE, but not a solution. This must be easy, just trying to get a cross browser solution to load a JS variable with an <input> value.
