will 'click' a different link.

I have included a file below that tests onKeyPress in Opera 7.11. I am
getting peculiar behavior. When the file is first loaded, pressing the
keypad + causes the textarea to get physically larger on the screen, and
pressing the keypad - causes the textarea to get physically smaller. I
click on the scrollbar then this behaviour stops and subsequent
keystrokes are displayed appropriately. Is this some kind of bug in
Opera 7.11? Code:

Does anybody know why doesn't onkeypress catch up/down arrow keys
while it catches left/right arrows? My only supposition is that up/
down keys are used for moving between form elements, anyway does
anybody know any solution to this problem?

I am working on a AJAX autocomplete script and the autocomplete is working, but I would like to add some more functionality to by adding navigation through the list with the UP and DOWN arrow keys. I seem to have the javascript working where when I press down one of the arrow keys it seems to change the className, but it immediately will change the className back to the original className.
Code:
document.onkeypress = KeyCheck;
var HighlightSelection = -1;
function KeyCheck(e){
[code]....
I know that the function "setHighlightSelection" is very basic, but it's being used for testing purposes.

In part of this project, I am create a dynamic table row that contains a dynamic textbox in one of its cells. When the textbox is created, I try to attach an onkeypress event and it only works in IE. I feel like I'm missing some fundamental piece here, and am pulling my hair out because of it :mad:. I feel like i've tried everything possible to even get firefox to read this code.
//----- WHERE THE TEXTBOX is CREATED -----//
var cellProd = row.insertCell(2);
var txtProdQuant = document.createElement('input');

I have a web page where I want to intercept keypress events in an INPUT-tag
and check if it is the Enter key, which calls another function that executes
a search. My code runs on Netscape 7 for Windows, IE 6 for Windows and IE5.1
for Mac, but not on Netscape 7 for Mac. When I press the Enter key, the
event gets caught but it does not get prevented and the search is never
executed.
The code looks like this:
function KeyDownHandler(e)
{
// if not Netscape, get IE event
if ( !e )
e = window.event;
if ( !e )
return true;
// Get valid ascii character code
var key = typeof e.keyCode != 'undefined' ? e.keyCode : e.charCode;
// process only the Enter key
if (key == 13)
{
// cancel the default submit
if (e.preventDefault)
e.preventDefault();
else
window.event.returnValue=false;
// submit the form by programmatically searching
search();
return false;
}
else
{
return true;
}
}

I have a select dropdown which has two events an onchange and onkeypress.
My problem now is when I use the keyboard arrows to select an item from the list in a select drop down the onchange is selected(invoked) before I even reach the second item in the list when using opera and IE but working fine with Firefox and chrome.The onblur event does not work either because the focus must be set to following tag

I am currently trying to figure out some event stuff with Javascript. I have the page capturing all onkeypress events by calling my function keyPress, and passing the event as an argument.
The key presses get passed to a text field that I have on the page (even if it's out of focus at the time of the key press) by using textfield.focus() within my keyPress function. This seems to pass the event along to the text field so that it registers the stroke and handles it as if the field was in focus at the time of the key press.
My problem lies in that I need to then grab the new value of the text field for use with another part of the script. It seems though that with the way I'm setting focus, it'll execute the rest of my keyPress function (with the outdated text field value) before the text field handles the event.
Is there a way to yield the event to this text field first?
Sorry, this was a long post, but I guess here's a short recap: If I handle key presses via the body of the page, so that regardless of the text field's current state of focus it updates the text field accordingly, is there a way to have that happen first before the rest of my function that needs to use the new value of the text field?

If I type characters using a Chinese text input (one where I type 2-3 latin characters for each Chinese symbol) there is no onkeypress or onkeydown event triggered. Any idea how to detect those characters please? I need to catch those chars in JS to pass them to a plug-in.

I have problem with event listening in CKEditor. I searched these forums for answer, but I didnt found it.
I need someting like "onkeypress" on textarea for CKEditor. If I think well, I can must use "DOM" of CKEditor, because it is not simple textarea - but I am lost here. I really dont know how to do it. I need simple draft saver - onkeypress will launch a function which will check if timer is on. If yes, return false. If no, use ajax to save content of textarea.

I want to switch a big function from a document.onkeydown = function to a document.onkeypress = function, or vice versa depeding on the type of browser.
However it is quite a big function so it's pretty much out of the question to have it appear in full twice.
Any ideas how to change the target event (onkeydown/onkeypress) without writing the whole function twice?

I am having a form with two input fields. I want to enter some text in the first input field and then the second field should get the same text. Is there a simple way (maybe a plugin) to do this with jQuery? It would be perfect if I even could output all these input fields values as normal text in <p> or <li> tags.

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 have a pretty basic set of things I want to do: Capture key press, compare against an allowed list, block keys that are not in that list, replace a space by a dash if entered. As this is happening, I have a span I wanted to be updated with the live values. The username field at [URL] is exactly what I am trying to do, though I have trouble dissecting how they did it. Here is my attempt, which is off by one keypress for some reason.
