JavaScript - Object Not A Collection Error
Hi -
New to Javascript - new to the forum... Here's one that I don't understand: Code: <script type="text/javascript">
fso = new ActiveXObject("Scripting.FileSystemObject");
myCollection = new Collection();
function FindFiles()
{
var path = "c:\\files\\";
var ext = ".csv";
var files = new Enumerator (fso.GetFolder(path).Files); //Collect all files in path
do
{
var file = files.item();
if (file.Name.indexOf("_summary")<0) myCollection.add(file.Name,file.Type);
files.moveNext();
}
while (!files.atEnd());
}
function Collection()
{
var collection = {};
var order = [];
this.add = function(property, value)
{
if(!this.exists(property))
{
collection[property]=value;
order.push(property);
}
}
this.exists = function(property)
{
return collection[property]!=null;
}
}
function ListCollection()
{
var g = new Enumerator (myCollection);
do
{
var colitem = g.item();
g.moveNext();
}
while (!g.atEnd());
}
</script>
During execution, I get a "Object not a collection" error when I try to pass "MyCollection" to the Enumerator function. What am I missing? Thanks, Max Similar TutorialsWhen I run this program is says I have an object error (not found?) in line 2, I went over the program which I copied from a book over and over and not finding anything wrong... Help!!! thanks HTML code he Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Making Sums</title> <script type="text/javascript" src="jsb-08-01.js"></script> <script type="text/javascript" src="jsb-global.js"></script> </head> <body> <h1>Making Sums</h1> <form action="addit.php"> <p><input type="text" id="inputA" name="inputA" value="0" /></p> <p><input type="text" id="inputB" name="inputB" value="0" /></p> <p><input type="button" id="add" name="add" value="Add" /></p> <p><input type="text" id="output" name="output" /></p> </form> </body> </html> Javascript code he Code: // initialize when the page has loaded

function addIt()
{
var value1 = document.getElementById("inputA").value;
var value2 = document.getElementById("inputB").value;
document.getElementById("output").value = value1 + value2;
}
i keep getting this error in explorer, while on chrome and on Firefox, it is just not working. this is the html table, (the relevant part is bold) Code:
<table align="center">

<td>

<td>
<input type="text" id="uname" name="txtname" value="שדה חובה" onmouseout="chkfld('uname')"

Hi, I have an "Object Required" error that only appears in IE and refers to a js file that I got elsewhere, so I'm kind of lost as to how to debug it. The page (which works fine in Chrome and FF) is here and the error reported is: Line: 7 Error: Object Required Sometimes it doesn't pop an alert, but mostly it does. thanks in advance for any suggestions. Hi guys i am trying to make my form out put inputs to the table below. however when i debug in ie9 it tells me error object expected for Code: <button onclick="document.getElementById('tablename').value=
document.getElementById('name').value">Submit</button>
how do i properly declare the object? the full code is below (i will obviously have more input fields just working it all out first) thanks david Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

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;
}

Thanks! Much appreciated! Kind regards, jo Hi All, I always get "Object Required" error when using IE (all IEs). No error when using FF. Message: Object required Line: 62 Char: 178 Code: 0 URI: I am using WebFXTabPane JS and always get error on line 62 or 63. Below is the excerption for line 62 and 63: }; WebFXTabPane.prototype.getSelectedIndex = function () { return this.selectedIndex;}; WebFXTabPane.prototype.addTabPage = function ( oElement ) { if ( !hasSupport() ) return; if ( oElement.tabPage == this ) return oElement.tabPage; var n = this.pages.length; var tp = this.pages[n] = new WebFXTabPage( oElement, this, n ); tp.tabPane = this; this.tabRow.appendChild( tp.tab ); if ( n == this.selectedIndex ) Thank you in advance for any help. Cheers, Jo Hello all, I am working on my website at http://www.productreviewsbytyler.com, and I have a little box with one input field for e-mail address collection. I am a novice who doesn't know what is the optimal solution for just collecting the data entered into the field. I have heard of scripts that test e-mail addresses. Confused 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, 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 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 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. 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.

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?
