Checkbox Event Listeners - Input Type?
May 24, 2009
When catcheck1 is unchecked, I want catcheck9 to uncheck. Why does this not work?
<html><head>
<script type="text/javascript">
// Checkbox event listeners.
function checkboxs() {
document.mapform.catcheck9.checked = false;
}
</script></head><body>
<form action="" name="mapform" id="mapform">
<input type="checkbox" id="catcheck1" name="catcheck9" onclick="checkboxs()" checked />
<input type="checkbox" id="catcheck9" name="catcheck9" checked />
</form></body></html>

I have a quandary of sorts here dealing with a list of checkboxes and the hiding/showing of a few divs associated with the checkbox selection. Here's basically what I need to do: Hide the lower div if no checkbox is selected. If any one of the first 6 checkboxes are selected, and NOT any of the remaining 6, then show the div. If at any time during selection one of the remaining 6 checkboxes are selected, then hide the associated div. Note this code doesn't really do much. I'm still trying to architect a solution that's best.
var aThroughf = false;
var gThroughl = false;
$('[name="'+q2030.name+'"]')).live('click', function() {

The DOM Level 3 specification has a section (1.2.2.2) that talks briefly about "groups" of event listeners. What does this mean? Is this similar to attaching event listeners with a namespace, as in jQuery: "event.my_namespace"?

Does the following indeed imply that this event is NOT called when an <input type="checkbox" is toggled?
This would thus imply the usage of the onClick handler instead (assuming an action needs to be invoked on check/ uncheck).
W3C Recomendation:
18 Scripts
onselect = script [CT]
The onselect event occurs when a user selects some text in a text field. This attribute may be used with the INPUT
and TEXTAREA elements.
I *know* the onClick can be used, I am just wondering about the use og onSelect.

try the the following code with Opera 9.01 (Windows). when clicked
slightly faster than normal clicking, the toggler checkbox and other
checkboxes displays differently although event method works fine to
update the checkboxes. there is not any problem with IE 6 or FireFox
1.5. also, i used the double click event method to see if its the
source but that does not help even. Opera 9.01 seems to be slow at
updating checkboxes visually. am i missing something or are there any
work arounds, solutions for this problem. Code:

I feel like I must be missing something simple but I can't put my finger on it...
I'm moderately new to JS (programmed in other languages though) and am working on a Google Maps project.
This piece of code should show an alert of the region's name when a map polygon is clicked. Instead, no matter what polygon is clicked, it only does the name for the LAST iterated placemark. code...
What am I missing? What would be a better way of handling this?

Does anyone know where I can find a complete list of DOM/DHTML event types documented?
I'm trying to learn more about advanced event handling in JavaScript and I'd like to find lists of event types that I can attach/add event listeners to. I've been searching around and I've found a few resources, but nothing that seems complete.code...

Here's the situation: I have a javascript object for controlling a custom DHTML scrollbar. So that I can use more than one on a page, the event listeners need to be passed a reference to the particular instance of the object that each needs to connect to, but as I discovered the hard way, inside an event listener, 'this' returns a reference to the DOM object throwing the event, rather than to the JS object. Short of coming up with a linked list of different objects and having the event handler search through it for the right object when an event is generated, then writing a reference to that object to some global variable, is there any convenient way to tie this together? I hope I've made myself clear enough...

So I know all about the caviats of the 'this' keyword when calling object functions from event listeners:
Code:
var foo = {bar: true, zoo: function() { return this.bar; }};
foo.zoo();
> true
a = foo.zoo;
a();
>
And I know that I can get around this by using an anonymous function so that 'this' is preserved in it's original context:
[Code]...
But then someone pointed out this article on memory leaks when using anonymous functions to call object methods because the anonymous function gets access to ALL variables in the enclosing environment and my not be properly disposed of by the garbage collector [URL] So that lead me to think about using a "3rd-person" approach to referencing object properties from within object methods.
[Code]...

I have PHP file called file1.php with an empty <div></div> in the middle. I've added a 'load' event listener so that on page load, it calls an AJAX function that calls file2.php. file2.php creates a table and loads it into the <div></div> in file1.php.
file2.php has <a> tags in it's <th> columns and I wish to trap when a user clicks on the column heading. The old way was to use the onclick() method but I'd rather use event listeners.
Here's my problem. I am getting "obj has no properties" when trying to add those listeners. I *think* it is because the code in file2.php isn't part of the original DOM tree for file1.php. So how can I use event listeners instead of onlclick()? I know I can add top the DOM by creating elements and appending them but that adds to the HTML code and my code is already in place via the AJAX call. What to do...? DO I just use the old passe onclick() method?

I am creating JS objects that have some properties that contain DOM nodes, and some of these DOM nodes have event listeners attached to them. When I delete such objects, do I first need to remove the event listeners attached to some of the DOM nodes? And do I need to use removeChild on the DOM nodes that are properties of the object? Or does JavaScript take care of all that?

As recently as 1.4.3 $('input:text') would find input elements with no type attribute, but after upgrading to 1.5.1 that is no longer the case.
Is this a bug or an intended refactor to be more standards compliant?
FYI - this is the selector I now have to use: $('input:text,input:not([type])')

I'd like to know if its possible to shift a select option field into a simple text field based on a check box filled by user.
I have an asp form that carries a few select options. One of them I'd like to permit free editing if the user selects a check box just biside the select option, so enableing free editing by user.

Is there a generic way to fire an event when the state/value of a checkbox is changed by another event - i.e. not a user action. In this scenario, I have a set of checkboxes with a "select all" checkbox. I have the code written such that checking or unchecking the "select all" checkbox updates the state of all of the checkboxes below.
The extra requirement here is that some of these checkboxes have "children". So, when you check one of these, its children are automatically checked as well. So, what I need to do is check the main "select all" checkbox, which would then check all of the immediate children, which would then check all of their immediate children. I tried both an onchange and onclick event, but neither seem to be firing.

I noticed that the image input type does not show up in the elements
array (IE 6.0).
<FORM name=myForm>
<INPUT name=rads id=check1 type=radio value=val1>
<INPUT name=rads id=check2 type=radio value=val2 checked>
<INPUT name=rads id=check3 type=radio value=val3>
<INPUT name=rads id=check4 type=radio value=val4>
<INPUT name=imgIn type=image src=web.gif>
<INPUT type=button name=somethin>
</FORM>
If I have this HTML code, the myForm.elements.length is 5, instead of
the expected 6. You can click on the image in this case, and it acts
like a submit button... proof that the broser recognizes it as part of
the form.
So, if I call myForm.elements[4], I get the button, not the image.
It seems goofy to me, and I cannot find any documentation that explains
why this is.
Of course, I can get access to the object in many other ways... I am
just curious if the is an IE bug.

This code:
if (stealth)
{
document.searchme.query.type = 'password'
}
else
{
document.searchme.query.type = 'text'
}
works in FF but not in IE 6. It fails with "Error: Could not get the
type property. This command is not supported."
A previous post mentioned that in IE type is 'read only'.
Are there any work around for changing input type dynamically in IE?

Is it possible to change the input type of a form field. example
<input type="password" name="pw" value="test">
i want to have a "view" button next to that field that when you press and hold it it will chnage that input type to "text" so i can see the password. And when i release the button it will change it back.
I know this sounds like a bad idea and insecure... but its not a big deal.. i have all this stored in an "administrator" panel which an admin must login to get to it. Inside of that i have some admin programs, one of which displays information about the clients. I want to be able to see the clients password when ever i need to reference what it is, but i figured rather then just printing it on the screen all the time this would be a better way.

When I click on the image form element
<INPUT type=image name=point src="map.png">
point.x and point.y values get submitted to the server
specifying where on the image I have clicked.
Is there any (simple) way to get ahold of that point.x and
point.y BEFORE they are sent to the server (and prevent
that from happening)? Ie. I just want the points where
someone clicks on an image and not interested in a submission
to the server.
