JavaScript - Ie8 Only Error: 'undefined' Is Null Or Not An Object

Hi
I am having trouble with a script. I cannot figure out why I get the message:
error: null is null or not an object (In IE8)

The site is: www.rayburns.com

I have check the javascript for the navigation bar and for the rotating images and cannot see what is missing. Not sure what is not being called.
Can someone please help with this.
Thank you in advance!

Hi,

I am getting an error on this code - sometimes! - and I'm not sure what it is. If I run this as is there is no error. If I add it into another page with other stuff it's ok for a while and then I get an error. So, I added my new page block my block to this code and waited for the error to appear so I could determine a conflict - but it was fine. And then a few clicks later the error.

This is the error in IE. In Firefox it seems to be fine lol.

Line 159
Char 3
'window.document.sendform.message_text' is null or not an object

Can someone make any suggestions?

Code:

 <script language="JavaScript" type="text/javascript">
  maxlen = 160;
  countLen();
	function countLen()
	{
		message_text = window.document.sendform.message_text.value;
		realLength = message_text.length;
		if (realLength>maxlen)
		{
			realLength = maxlen;
			window.document.sendform.message_text.value = message_text.substring(0,maxlen);
		}
		message_text = window.document.sendform.message_text.value;
		// del enter
    var m = message_text.match(/[\r\n]/);
    if (m !== null)
    {
        window.document.sendform.message_text.value = message_text.replace(/[\n\r]/g, '')
    }
		window.document.sendform.messlen.value=maxlen-realLength;
	}
	
</script>

 
 <cfset thismessage = "Hi, is this a start">
 
 
 
 <cfform action="step2.cfm" method="post" id="sendform" name="sendform">

Hello

I am using a timer which goes down from 2 minutes to zero when 'jsp' is called. Timer is written in javascript. I am getting an error that document.form1.timerMin.value=<%=min%> is null or not an object.
Here is the code (t.jsp):
<%
/* Default timer */
int min = 2;
int sec = 5;

/* Check for timer params */
try {
String timerMin = request.getParameter("timerMin");
if (timerMin==null)timerMin="";
if (timerMin != null) {
min = Integer.parseInt(timerMin);
}
String timerSec = request.getParameter("timerSec");
if (timerSec==null)timerSec="";
if (timerSec != null) {
sec = Integer.parseInt(timerSec);
}
}

catch(Exception m) {
System.out.println("generated exception..............:"+m);
}

%>

<script language="JavaScript" type="text/javascript">
<!--

/* Initialise timer */
var min = <%=min%>; // set the minutes
var sec = <%=sec%>; // set the seconds
function countDown() {
sec--;
if (sec == -1) {
sec = 59;
min--;
}

/* Write timer state to hidden form fields */
document.form1.timerMin.value=<%=min%>
document.form1.timerSec.value=<%=sec%>;

time = (min<=9 ? "0" + min : min) + " min and " + (sec<=9 ? "0" + sec : sec) + " sec ";
document.getElementById('theTime').innerHTML = time;

SD=window.setTimeout("countDown()", 1000);
if (min == 0 && sec == 0) {
window.clearTimeout(SD);
}
}

window.onload = countDown();
-->
</script>

<style type="text/css">

Looking forward for an early reply.

Hi,
I have added an validation script for Pizza menu. Validation working fine in all browsers except IE.
When I working in IE8 it throws an error "length is null or not an object error in IE8".
Please help me. See Java script code below:
<script>
function UnCheckRadios(radioButtonGroupName)
{

var formName = "frmOrder";
var form = document.forms[formName];
alert(form);
var noOfRadioButtons=form[radioButtonGroupName].length;
for(var x=0;x<noOfRadioButtons;x++)
{
chk=form[radioButtonGroupName]
.checked=false;

}
}
</script>

PHP code:
<input type="radio" id="<?=$subitem['subgroup_id'];?>_comboleft" name="<?=$subitem['subgroup_id'];?>_comboleft" value="<?=$subitem['id'];?>:Left Side" onclick="UnCheckRadios('<?=$subitem["subgroup_id"];?>_combowhole');">

Hi

I am using a custom form elements script in the link below:

www_bristolstreet_co_uk/page/find_a_dealer.htm

and an error for null object is appearing from this line:

active = option[0].childNodes[0].nodeValue;

Can anyone please help? I am a novice at Javascript but got this script working perfectly on my local machine - once I loaded it the live site it didn't work... any advice would be greatly appreciated.

Hi, first post here. I was working on code for opening a link in a new window when clicked. I read somewhere that it's a good idea to remove all of the javascript elements from the HTML. So I pieced it together and it works. But I get the following error in IE8:

Code:

Message: 'document.getElementById(...)' is null or not an object

Here's the relevant HTML:

Code:

<a href="http://www.samplesite.com" id="sampleid">Sample Text</a>

And here's the relevant javascript that I put in a seperate .js file:

Code:

function samplefct() {
window.open(this.href);return false;
}

window.onload = function()
{document.getElementById("sampleid").onclick = samplefct;
}

The code does work as planned. But I'd still like to get rid of the error. Can anybody think of a different way of stating the javascript that would perform the same thing and lose the error?

Any help would be greatly appreciated.
Thanks!

Hey Guys,

I wondered if anyone would be kind enough to look at an issue I am having running a Javascript on IE.

The script works fine in FF and Chrome but chucks up an error in all versions of IE so the Menubar does not display child pages.

Here's the Error:

Timestamp: Tue, 16 Aug 2011 14:45:53 UTC

Message: 'lastChild' is null or not an object
Line: 31

The full script is he http://www.makingtrails.com/wp-conte...ks3/js/menu.js

Any help much appreciated as the author of this script is not providing any support.

Thanks

Hiya,

I would like to ask your help regarding this damned error message that comes out only in Internet Explorer and makes impossible to submit the form.

The javascript code is:

Code:

And when trying to submit the form, I get the error message:

        Code: 0
        Error Message: 'undefined' is null or not an object
        URL: https://localhost/ruff/scripts/validationVol.js

Do you have an idea what could be the problem? As I checked line 177, it seems to be OK. I checked the web, but didn't find anything related to this message in a situation like this.

Thanks in advance for your comments.

Hey,

I have made/modifying a script that I can create AJAX objects on the fly. It is working fine in Chrome, FF, Opera, Safari but not IE -.-
IE = nightmare

Code:

function ajax_object() {
	this.receive = function(serverAJAXpage, whileLoading, onDone, dataIntoDivID) { 
		this.xmlHttp = createAjaxObject();
		this.serverAJAXpage = serverAJAXpage;
		this.xmlHttp.open("GET", this.serverAJAXpage, true);
		this.xmlHttp.send();
		this.xmlHttp.onreadystatechange = function() {	
			if (this.readyState == 1) { 
				eval(whileLoading);
				//document.getElementById(mydiv).innerHTML=this.responseText;
			}
			if (this.readyState == 4) { 
				eval(onDone);
				if (typeof dataIntoDivID != "undefined") {
					document.getElementById(dataIntoDivID).innerHTML = this.responseText;
				}
				
			}
		}
	}
	
}
function createAjaxObject() {
	var xmlHttp=null;
	try {
	  	xmlHttp=new XMLHttpRequest();
	}
	catch (e) {
	  	try {
	    	xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
	    }
	  	catch (e) {
	    	xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
	    }
	}
	return xmlHttp;
}

There is the function that handles the object


and here is the objects being used:
Code:

<script>
	var onlineUsersAJAX = new ajax_object(); onlineUsersAJAX.receive('ajax/onlineUsers.php', '', '', 'onlineUsers');
	var recentPostsAJAX = new ajax_object(); recentPostsAJAX.receive('ajax/recentPosts.php', '', '', 'recentThreads');
</script>

IE throws the error:
'ajax_object' is undefined


Thank you to anyone that can help =)

Hi i have done some reading on the net today because i am getting an error on ie. 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.

Code:

i was on 1.5 swfobject i did download 2.2 and im guessing all you do is replace the swfobject.js file to upgrade it, but what happened is it gives me this now.

i dont mind going back to the old version i just need to get this working and im soooooooo lost lol


ok another update, this is becomming maddening lol. once i have this line in the header php

Code:

<script type='text/javascript' src='$CONST_LINK_ROOT/swfobject.js'></script>

I never have to use it again as long as they header php is included correct?


This is what is driving me nuts, im back on 1.5 and it says its undefined


Code:

but am in not defining it on this line? ---> var s1 = new SWFObject('player.swf','player','400','300','9');


<script type='text/javascript' src='swfobject.js'></script>

s1.write('preview');
</script>

Another Update. I am back to the original question. null is null or not an object.. in my search i have found this

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

Hi
I've implemented Busybox on a website to display FLV files in a popup player. This works fine, except for the following error in IE (FF is fine) when I close the popup: 'null' is null or not an object

I think I've narrowed it down to the following block of code, but am stuck as to what to do from here.

Code:

var cl = new Element('img',{
		'styles':{
			width:'24px',
			height:'24px',
			position:'absolute',
			top:'-20px',
			right:'-20px',
			'z-index':'100000'
		},
		'src':'bumpbox/closed.png',
		'id':'closer'
	})

cl.addEvent('click',function(e){
			e = new Event(e).stop();
		
			bg.dispose();
			$(el).getChildren().dispose();
			eff2.start({
			  'width':[maxw,1],
			  'height':[maxh,1],
			  'left': [endleft,middleH],
			  'top':  [endtop, middleV+s]
			 })
		})

The IE error is just giving me line number 1 of the php, but the error, I'm sure, lays in the Javascript.

Many thanks

Hi, im having a little difficulty checking if an XML node has a value, here the code:

var Divs=new Array("artist","bio","img","date","tickets","venue","street","city","country","headliner");

xmlDoc=xmlhttp.responseXML;

for ( nodes in Divs )
{

if(!xmlDoc.getElementsByTagName(Divs[nodes])[0].childNodes[0].nodeValue)
{
}
else
{
document.getElementById(Divs[nodes]).innerHTML=
xmlDoc.getElementsByTagName(Divs[nodes])[0].childNodes[0].nodeValue+"<br>";
}

}

This always throws up the error: document.getElementById(Divs[nodes]) is null

ive tried putting the xmlDoc in a variable then checking if its null but no luck, also tried the same method against "undefined" but no luck either.

Would be greatful if anyone has any suggestions.

Thanks, Tom.

Whenever i try to use this function it gives me either -

function XCoordToSAN(x)
{
  // Convert the x coordinate of the piece to partial SAN (Simplified Algebraic Notation)
 for(var xCoord = 0; xCoord >  xCoord * 7; xCoord++)
    {
	 if(x == xCoord * BlockSize)
	   {
	    var SANx = xCoord;
	   }
	}
return SANx;
}

function YCoordToSAN(y)
{
var Letters = ["A", "B", "C", "D", "E", "F", "G", "H"];

// Convert the y coordinate of the piece to partial SAN (Simplified Algebraic Notation)
 for(var yCoord = 0; yCoord >  yCoord * 7; yCoord++)
    {
	 if(y == yCoord * BlockSize)
	   {
	    var SANy = Letters[yCoord];
	   }
	}
return SANy;
}

this is how i'm calling the functions:

Code:

var oldPGNx = XCoordToSAN(oldXposition);
  var oldPGNy = YCoordToSAN(oldYposition);
  var newPGNx = XCoordToSAN(newXposition);
  var newPGNy = YCoordToSAN(newYposition);
  
  NewPGNData = oldPGNx + oldPGNy + "-" + newPGNx + newPGNy + " ";
  // Finally update the Data
  document.getElementById("PGNArea").value = OldPGNData + NewPGNData;
