Keypress Event In DOM?
Jun 18, 2003
DOM2 does not provide a key event module. (http://www.w3.org/TR/2000/REC-DOM-Level-2-Events-20001113/events.html#Events-eventgroupings-keyevents) That's fine. I'm down with that.
According to the DOM3 Events spec (http://www.w3.org/TR/2003/WD-DOM-Level-3-Events-20030331/events.html#Events-KeyboardEvents-Interfaces) (in last call), there's no keyPress event, only keyDown and keyUp. Instead (I guess) they've defined a new interface for text events (http://www.w3.org/TR/2003/WD-DOM-Level-3-Events-20030331/events.html#Events-TextEvent), which provides one event type: textInput.
Should I not code event handlers for keyPress events if I wish to write DOM-compliant scripts? IE & Moz both register a keyPress; I'm sure that it won't be outphased. I worry instead about a new and better browser appearing and balking on my script because it's coded exactly to spec.

look at this script :
$(function(){
$('input').bind('keypress',null,b).bind('change',null,a);
});
function a(){
[Code].....
this script bind both keypress and change of the text box to functions b and a. at keypress event handler if user type a char on input box the value of input box change to x and the user char discarded. In this case we expected to run the onchange (change) event because the textbox value is changed BUT this doesn't happen.

I have:
<div onkeypress="go(event)">...</div>
and:
function go(event) {
alert(event.keyCode);
}
but I always get 0 for the keycode.

Hi have an event called function allownumberonly(evt);
My html text input onkeypress calls this function.
onkeypress=allownumberonly(event)
I want to create a text input dynamically and set its onkeypress event
to the above function also passing the event.

Is there any cross-browser method of determining whether a click event was triggered by a mouse left click or the keyboard's 'enter' key? I was expecting event.button, or event.which to be able to do this, but this doesn't seem to be the case. Checking event.clientX == 0 && event.clientY == 0 works in FF, but not in IE.

Code...
I'm getting an error object required on the window.onkeypress line.
I have a data entry app and the users are keying with their right hand on the number pad and flipping pages with their left. If they want to use the normal tab key they have to take their hand off of the papers to do so. I figured it would be pretty simple to override the keypress even for the + key and divert it to act like tab was pressed instead.

I am trying to run some code if a series of keypresses the user types is equal to the correct series of keypresses.I know how to do this if I am just trying to get one keypress. But what about one after another?

I've got a script which is called by a keypress event, something like this:
<html>
<head>
<script type="text/javascript">
function respondToKey(e) {
keyPressed = String.fromCharCode(e.which);
if(keyPressed == 'g'){
alert('you pressed the g key');
window.open('http://google.com');
}
}
</script>
<title>Untitled</title>
</head>
<body onkeypress="respondToKey(event)">
hit the g key to open a google window
</body>
</html>
when you hit the right key, the alert appears, but the window.open() never happens. There's not even a message in the Error Console, just nothing.
Is this a security feature? Any way I can get around it? And, if it's a security feature, is the fact that it fails silently with no error message also a security feature? Because it's rather annoying.

As the subject says it, is there a way to simulate a special keypress in JS
? In my case, on loading an HTML page, i'd like to set the cursor at the end
of the input text of an <input type=text ...> object. focus() sets the cusor at the beginning Any idea ?

I have a text box where the user enters their employee email address.
What I want to occur is when the @ sign is pressed it will
automatically add the rest (ie. mycompany.com)
I know the code required to alter the value of a text box but I dont
know the event trigger or code to detect the keypress.

I am trying to catch keypresses in my canvas tag, but it appears that
that is not valid.
I may try to just create a hidden input box that will allow me to catch
keypresses.
I am trying to write a very simple asteroids game for a presentation on
Ajax in July, to show that javascript can do more than it was able to a
couple of years ago.

Ive scoured the internet for scripts that make a <div> follow the mouse, and have found one that seems to work well. However, I want the <div> to stop moving when the CTRL or the SHIFT key is pressed, I dont care which. Hopefully, I can have a div that follows the mouse at an offset that contains some click-able items, so a menu is always by your mouse. Ive tried now more than a few times to put together a piece of code that can achieve this, but none have worked. Can somebody write a script that can achieve this, or point me in the right direction?Current JS for mouse follow:
var divName = 'mouseFollow'; // div that is to follow the mouse
// (must be position:absolute)
var offX = 15; // X offset from mouse position
[code]....

How do I capture the keycode inside a <textarea> in NN6+ and IE5.5+? I don't
want to add add document.keyPress function because I only want this to
occure when a specific textarea is selected and not fire for every keypress
in the entire document.
<textarea onkeypress="captureKeys();"....
but I cannot get a reference to the current event so i can ask for the
keyCode. In IE I can check the event.keyCode inside my function captureKeys
but this is not possible in NN6+.

I have an <input> box and i want to disable the apostrophe ( ' ) key, so
when you press it, no character appears in the input box. All other keys
should work ok.
I can trap the keypress event using "onkeypress=myKeypressHandler()" but,
beyond that, I'm stuck. I forget how to detect what key was pressed or how
to "null it out".
I'm using IE6 and users will be IE5.0 upward ONLY (trust me on this, suffice
to say it's not a website but an intranet application).

I've got a page that looks a little like this...
<input name="myField" id="myField" type="text"><br/>
<div id="output"></div>
<script type="text/javascript">
[Code]...
The basic behavior that I want is for the output text to match exactly what I'm typing in input field above. The problem is that my output field lags behind my input field by a single letter. (I type in "hello world" and the output field says "hello worl") I'm guessing maybe that at the time the keypress event is fired, the letter hasn't actually been entered yet into the form field, but I don't know for sure.
Is there any simple way to get my output field to match up with what's in my input field in the above code snippet? Workarounds I've thought of are a) using keyup instead of keypress (works, but feels laggy), or b) Converting the event keyCode into a letter and appending it onto the end of the string (seems more complicated than it ought to be)

Is there a way of simulating a mouseclick in a div from a keypress?
In other words, if I press 2, I want it to simulate me actually having clicked in the div <div id="jplayer_next2"><a href="#">next</div>
Long version (for anyone wondering "WHY?")
Using the jplayer jquery plugin:
For some reason (and after 2 days I've given up trying to find out) I can't seem to directly call the function which is defined right there on the page:
function playListNext() {
var index = (playItem+1 < myPlayList.length) ? playItem+1 : 0;
if( index > 0 ) {
playListChange( index );
[Code]....

I have the following going on:
<script type="text/javascript">
$(function(){
$("#addtext").keypress(function (e) {
var c = String.fromCharCode(e.which);
[Code]....
When I type a character into the input field, it gets echoed twice in the target area. I know it is getting fired twice because the alert box will pop up twice.

A common javascript function that capitalizes input as user types (onkeypress) no longer works as of IE9Need a function that also works in IE 9 that doesn't not change method call or interface (as it's used in 150 places throughout application).
CALL:
[CODE]
el.onkeypress = function(el) {
return c_capitalizeInput(el);
}
[CODE]
FUNCTION:
[CODE]
// Intercepts keyboard input and capitalizes keystrokes.
// Call with onkeypress="return capitalizeInput(event);"
// Compatible with both IE and Netscape/Mozilla
function c_capitalizeInput(evt) {
evt = (evt) ? evt : ((window.event) ? window.event : "");
if (window.event) {
// IE
if ((evt.keyCode >= 97) && (evt.keyCode <= 122)) {
evt.keyCode = evt.keyCode - 32;
} return true;
} else if (evt.which) {
// Netscape and Mozilla
key = evt.which;
if ((key >= 97) && (key <= 122)) {
key = key - 32;
evt.target.value = evt.target.value + String.fromCharCode(key);
return false;
} return true;
} else {
return true;
// Can't do anything for other browsers
}
}
[CODE]

I'm working on a project where I have to apply filtering as used on one table (using the jQuery datatables plugin) to a next table (which is using the picnet.table.filter plugin).
Now, I have been able to retrieve the values used to filter from the original table, and I have been able to put them as filterValues in the other table, but ..the table does not automatically filter correctly. I first have to press 'enter' (or add a space) to one of the values. when I do this, the filtering works perfectly.
My problem is, I want this filtering to be applied as soon as I open the page, since the heading of the table will be hidden, and the user is not supposed to have the opportunity to see or change the filter-boxes.
Does anyone know if there is an efficient way to simulate pressing enter using javascript?
