Checkbox Checked Property "undefined" In IE

Oct 6, 2005

The following code:

function checkChildMenuItems(strNameModule)
{
alert(document.getElementById(strNameModule).check ed);
}

<input name="strMenuQA" id="strMenuQA" type="checkbox" value="1"
onclick="checkChildMenuItems(this.id);" checked="checked">

shows "true" or "false" in Firefox, when I respectively check or uncheck the checkbox. IE however comes up with "undefined". Is this code so exotic, that IE has problems with it?

Undefined Checkbox - Labels To Be Turned Off To Begin With And Switched On If The Box Is Checked

Apr 25, 2011

I am using a checkbox to turn on and off some labels on a line on a google map, which is working fine if the line is already drawn, using this function:

function distboxclick(labelsbox) {
if (labelsbox.checked) {
for (var i=0; i<distmarkers.length; i++) {
if (distmarkers[i].mLabel != null) distmarkers[i].mLabel.show();
}
} else {
[Code]....

but the thing is that I want the labels to be turned off to begin with and switched on if the box is checked.

Undefined Property Freezing IE

Nov 29, 2011

This is my first post while learning Javascript and jQuery as total noob.

I have something like this:

var desc = "This is your title and here is even more that might be added so that we can get at least 60 characters or so"[code]...

It is actually being used on a page that calls a description from a MySQL table, but this example fails in exactly the same manner. Although FF and other browsers successfully initiate the script with errors, but IE loops endlessly and freezes up. FireBug reports "reference to undefined property a[d]". Using jQuery 1.6.2.

Uncaught TypeError: Cannot Read Property '$divref' Of Undefined

Jun 28, 2010

I have a page which has some content that is generated via an AJAX request and JSON. The content is shown and hidden by clicking on each row using the (Animated Collapsible DIV v2.4 script ). It works fine if I have the page as one static file (which I did for testing) showing the same content the AJAX pulls. But when I display the page with AJAX generated content it comes through and the source code is essentially the same but my show/hide effects are not working. I am getting an error when I troubleshoot using Google Chrome Developer Tools that says: Uncaught TypeError: Cannot read property '$divref' of undefined. I tried switching the order of the Javascript and HTML to see if that was the problem. But I think it has something to do with the way the page is loading in the AJAX based version. I looked into using the JQuery LiveQuery plugin but I could not figure out how to make it work with my code nor do I know if it is the fix I need anyways.

JQuery :: Uncaught TypeError - Cannot Read Property Guid Of Undefined

Mar 26, 2010

I have the following JQuery code:
$("#menu-247 > a, #menu-213 > a, #menu-214 > a, #menu-215 > a,
#menu-216 > a, #menu-218 > a, #menu-219 > a").addClass("mainLevel");
/*$(".mainLevel").each(function (i) {
$(this).before('<div id="' + $(this).parent().attr("id") + '-behind"> </div>');
$(this).prev().css({
width: $(this).css("width"),
height: $(this).css("height"),
position: "absolute",
top: "0",
left: $(this).parent().css("left"),
zIndex: "5",
display: "none",
backgroundColor: "blue"
});
$(this).css({
position: "relative",
zIndex: "10"
});
});*/
$(".mainLevel").hover(function() {
alert('test');
});

And I receive the error "Uncaught TypeError: Cannot read property 'guid' of undefined" in Google Chrome. I thought it had to do with the fact that the event handler was trying to be added before the DOM was modified. But then I tried simply this:
$("#menu-247 > a, #menu-213 > a, #menu-214 > a, #menu-215 > a, #menu-216 > a,
#menu-218 > a, #menu-219 > a").hover(function() {
alert('test');
});

And still received the error. I removed all the "> a" so I simply had a list of ids and the error was still there. Even when I only have one id listed, the error comes up! It also seems to be any element. But if I just try the alert part, everything works.

Can't Get Checkbox Checked In IE

May 31, 2005

I'm trying to dynamically create a checkbox element with the checked status being true however it never works in IE, I've tried everything I can think of. The code works in firefox but IE never checks the box, when I do an alert it says its checked but it does not render the check.

var chk_box = document.createElement("input");
chk_box.checked = true;
chk_box.setAttribute ("type","checkbox");
chk_box.setAttribute ("name","vulns"+i);
chk_box.setAttribute ("value","1");
item.appendChild(chk_box);

I've also tried: chk_box.setAttribute ("checked",true);

and item.lastChild.checked = true;

none seem to work in IE, any tips?

Change Value Of Checkbox If Checked?

Jun 11, 2011

I have a checkbox in a form. The form is submitted via ajax everytime a users makes any chenges to the drop down menu's in it and returns an updated value. That part is fine. the part I'm having issues with is the checkbox in the form. Initially it is set to checked. The proble I have is that when the ajax script runs it takes the value from the checkbox regardless of whether it is checked or not!

How can I get around this? Is there a way to set an initial value and another checked valus on the checkbox? I've had a look and can't find anyway to do this.

CheckBox - Sum Values To Textbox When Checked

Apr 30, 2010

The problem I have is that the value="" needs to be the ID number of the recordset but still be able to SUM the dollar value on the TEXT box (totalcost) when someone click on each CHECKBOX. The CHECKBOX values will be coming out of a database using PHP. How do I modify the Javascript to accomplish what I'm looking for.

Code:
<script type="text/javascript">
function UpdateCost() {
var sum = 0;
var gn, elem;
for (i=0; i<5; i++) {
gn = 'game'+i;
elem = document.getElementById(gn);
if (elem.checked == true) { sum += Number(elem.value); }
}document.getElementById('totalcost').value = sum.toFixed(2);
}
</script>
<form action="<?php echo $editFormAction; ?>" method="POST" name="form1" id="form1">
<input type="checkbox" id='game0' value="9.99" onclick="UpdateCost()">Game 1 ( 9.99)<br>
<input type="checkbox" id='game1' value="19.99" onclick="UpdateCost()">Game 2 (19.99)<br>
<input type="checkbox" id='game2' value="27.50" onclick="UpdateCost()">Game 3 (27.50)<br>
<input type="checkbox" id='game3' value="45.65" onclick="UpdateCost()">Game 4 (45.65)<br>

Checkbox Visible But Status Undefined?

Aug 11, 2011

The following excerpt is part of a very huge project(in terms of code involved). Pardon me if it lacks a bit of context. But I assume I have posted adequate information for understanding the problem.

var sztitlebar_specific= "<table cellpadding='0px' cellspacing='0px' width='100%'><tr>" +"<td class='tiletitle'>"
"<img src='../images/alert.gif' onclick='toggleAlerts("#ID#")' alt='Toggle Alerts' title='Toggle Alerts' style='cursor: hand'>" +

[Code]....

But when I alert the status of the checkboxes they show up as "undefined". As you can see, the first piece of code defines a titlebar with a button and a couple of checkboxes and the name of the titlebar. And it is these checkboxes that remain undefined even though I can see them and check and uncheck them. But the name of the titlebar gets passed to the function correctly when the onclick event fires and it gets alerted.

I have a simple form which I am running a validation on a single text box (as shown below, adapted from the milk example).

// validate signup form on keyup and submit
var validator = $("#updateModules").validate({
rules: {
guestbookContact: {
required: true,
email: true
},
},
// the errorPlacement has to take the table layout into account
errorPlacement: function(error, element) {
if ( element.is(":radio") )
error.appendTo( element.parent().next().next() );
else if ( element.is(":checkbox") )
error.appendTo ( element.next() );
else
error.appendTo( element.parent().next() );
},
// specifying a submitHandler prevents the default submit, good for the demo
submitHandler: function() {
form.submit();
},
// set this class to error-labels to indicate valid fields
success: function(label) {
// set   as text for IE
label.html(" ").addClass("checked");
}});

Now I only want to validate the text box if the checkbox "requireEmail" is checked. Is there an easy way to do this?
