JavaScript - Javascript Menubar Error 'lastchild' Is Null Or Not An Object
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: User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729) Timestamp: Tue, 16 Aug 2011 14:45:53 UTC Message: 'lastChild' is null or not an object Line: 31 Char: 3 Code: 0 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.

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?

Thanks! Much appreciated! Kind regards, jo I have a bug that is only seeming to effect IE 8:. It seems to have a problem with this line: theSelectBox.selectedIndex = -1; This is where my full page is: http://www.mauirealestate.net/advancedsearch-rets.php Also has a weird display issue in IE8, but not in "compatibility view", which the bug may fix. Works and looks beautiful is Safari and Firefox. Any suggestions are helpful. 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 have a an application which works fine on XP IE6, but the same application throws error " Java Script Error Style is null or not an object" on XP IE8 and Windows 7 . Please help me to resolve this issue. Please Tahnks in advance 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! IB I am not very experienced at javascript. Having trouble with some I used for a google map on some of the pages on company site. Appreciate any assistance someone out there could give. If you go to http://www.ghd.com/global/locations/...nsland/cairns/ you can see the error.

İ want to use this code but when the page opens, I get a null reference error. When I open the page a second time, this error doesn't occur. I understand when the site caches, this error doesn't occur. The error comes from tb_show function. My code: <script type="text/javascript"> function writeCookie(CookieAdi) { var dtGun = 1 var strValue = "1" if (dtGun == null || dtGun == "") dtGun = 365; var d = new Date(); d.setTime(d.getTime() + (dtGun * 24 * 60 * 60 * 1000)); var zt = "; expires=" + d.toGMTString(); document.cookie = CookieAdi + "=" + strValue + zt + "; path=/"; } function readCookie(cookieadi) { var c = document.cookie; if (c.indexOf(cookieadi) != -1) { s1 = c.indexOf("=", c.indexOf(cookieadi)) + 1; s2 = c.indexOf(";", s1); if (s2 == -1) s2 = c.length; strValue = c.substring(s1, s2); return strValue; } } writeCookie('OnerFacebook'); if (readCookie('OnerFacebook') != 1) { tb_show('', 'http://www.mobilyala.com/OnerFacebook/?KeepThis=true&TB_iframe=true&height=500&width=300&modal=true', ''); } </script> What should I do for it? 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.

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 All, I am using javascript to get the number of rows in my HTML Table by using below code: Code: var oRows = document.getElementById("HTMLTable").getElementsByTagName('tr');
var iRowCount = oRows.length;
Later I am using iRowcount in the FOR loop further in my code as below: Code: for(k=1; k<=iRowCount; k++) {
............................
rest of code ...........
............................
}
This piece of code is working fine (i.e. it handles the functionalities which is needed) but it also opens a new browser window with the error message "Object Required".I have really no idead why this is happening.Can anyone suggest me the reason for this? Thanks in advance. -Anil I am trying to understand why I had an error, or why my solution worked. In my HTML I had: Code: <script language="JavaScript" type="text/javascript" src="Book.js"></script> <script language="JavaScript" type="text/javascript" src="Book_TEST.js"></script> Book.js said: Code: function Book(title, author)
{
this.title = title;
this.author = author;
}
Book.prototype.toString = function()
{ return '"' + this.title + '" by '+ this.author; };
var Book = new Book ("John", "Dough");
alert (Book); // displays "John Dough"
And, predictably, at this stage, the code worked. Book.js said: Code: var myBook = new Book ("JavaScript Tutorials", "Herong Yang");
However, at this point the JavaScript would crash and I'd get an error "Error: Book is not a constructor javascript." I drove myself nuts trying to figure out why the code wasn't working at this later point. Eventually, I copied another object: Code: /*
* Person class
*/
/**
* Person constructor
*
* @param {String} first
* The person's first name
* @param {String} last
* The person's last name
*/
function Person(first, last)
{
this.first = first;
this.last = last;
}
/**
* Create a string representation of this object
*
* @return {String} A string representation of this object
*/
Person.prototype.toString = function()
{
return this.first + " " + this.last;
};
/*
var person = new Person ("John", "Dough");
alert (person); // displays "John Dough"
*/
and then used find and replace to swap {Person, first, last} with {Book, title, author}, resulting in: Code: /*
* Book class
*/
/**
* Book constructor
*
* @param {String} title
* The Book's title
* @param {String} author
* The Book's author
*/
function Book(title, author)
{
this.title = title;
this.author = author;
}
/**
* Create a string representation of this object
*
* @return {String} A string representation of this object
*/
Book.prototype.toString = function()
{ return '"' + this.title + '" by '+ this.author; };
var Book = new Book ("John", "Dough");
alert (Book); // displays "John Dough"
Now, the code worked fine in both script. (i.e., no more error.) So far as I can tell, the only differences between the first and next version of Book.js are the comments and the whitespace. Am I missing something? Can the comments or whitespace somehow effect the logic with which this code has been executing? If I get an error like this again, is there an easier/better way to fix it than to essentially retype the code? Thanks in advance for helping me to understand this. hi, I am trying to setup an iphone application in Dashcode using what I have he http://www.mypubspace.com/dashtest/order.html Result of expression 'ajaxDisplay' [null] is not an object which is on the following line: Code: ajaxDisplay.innerHTML = ajaxRequest.responseText; is there a way around this? thanks Hello, I'm working on web apps for a company and unfortunately the websites work in Mozilla, chrom and IE9 but not in IE8.
