I have a code to disable ctrl-v (paste) on the 2nd box. The problem
is that when I type ctrl-v, the text shows, then disappear
after I release ctrl-v. How can I make it not to show in the box. In
VB, I can set keyascii=0 to kill the input. Is there a similar way to
do it in JavaScript? Thanks a lot.
<HTML><head></head><body>
<form name="myForm">
Password: <input type="text"><br >
Comfirm: <input type="text" name="myText"
onKeyUp = "fncKeyStop();" > </form>
<script>
function fncKeyStop(){
if (window.event.c trlKey){
if (window.event.k eyCode == 86) {
document.myForm .myText.value = ""
}
}}
</script></body></HTML>

The type attribute is mandatory. This should read:
<SCRIPT type="text/javascript">
function fncKeyStop(){
if (window.event.c trlKey){
if (window.event.k eyCode == 86) {
document.myForm .myText.value = ""
You should access forms and form elements using their respective
collections:
document.forms['myForm'].elements['myText'].value = "";
}
}}
</script></body></HTML>
Use both the onkeyup and onkeydown events. That way, it will fire
when a key is pressed once, and when it's released (if held long
enough for the keystroke to repeat).
You should also change the function content to:
function fncKeyStop() {
// Check if the control key is pressed.
// If the Netscape way won't work (event.modifier s is undefined),
// try the IE way (event.ctrlKey)
var ctrl = typeof event.modifiers == 'undefined' ?
event.ctrlKey : event.modifiers & Event.CONTROL_M ASK;
// Check if the 'V' key is pressed.
// If the Netscape way won't work (event.which is undefined),
// try the IE way (event.keyCode)
var v = typeof event.which == 'undefined' ?
event.keyCode == 86 : event.which == 86;
// If the control and 'V' keys are pressed at the same time
if ( ctrl && v ) {
// ... discard the keystroke and clear the text box
document.forms['myForm'].elements['myText'].value = '';
return false;
}
return true;
}
....and the intrinsic event bodies to:
<INPUT ... onkeyup="return fncKeyStop()"
onkeydown="retu rn fncKeyStop()">
This works in Internet Explorer and Opera. It should hopefully work
in Mozilla and Netscape too, but I can't test them.
Hope that helps,
Mike

Presumably this is to stop users from pasting their email address having
typed it once. If so, may I say how annoyed I would be as a user.

Not really.
There is a "default scripting language" for a page. It can be set
with the META tag shown below. It is the default scripting language
for all scripts on the page.
There is no default *value* for the script tag's type *attribute*.
Furthermore, the type attribute is required, so in practice, the
default scripting language doesn't apply to script elements.
The "default scripting language" and the "type attribute" of script
tags are completely independent. The latter has no default value. <META http-equiv="Content-Script-Type" content="text/javascript">
Does this replace the TYPE attribute in the SCRIPT tag?
No. It's not about script tags at all. Script tags require the type
attriubte. The intrinsic event attributes (e.g., "onclick") have no
type attribute, and they use the default scripting language of the
page.
Intrinsic events:

It is a password confirm box, AFAICS, which means that using ^V rather
defeats the object of having a confirmation.

In which case, shouldnt the form object be of type=password? iirc, that
type has cut and paste functions disabled as a 'security' measure.

It's not an interpretation, that is quoted verbatim. The only edited
sections are the descriptions of the src and defer attributes (which
I removed completely). <META http-equiv="Content-Script-Type"
content="text/javascript">

The type attribute is required. That why the specification says (as
you quoted!): "Authors must supply a value for this attribute." The
Content-Script-Type META element or HTTP header is used when parsing
intrinsic events. It is explained in section 18.2.2, Specifying the
scripting language, of the HTML 4.01 specification.

You do not RC! Copy and Cut are disabled, but Paste works, in my
browser, in a Password box. But it seems likely that it should be
type=password.

How do you know that Ctrl-V is the shortcut for Paste? You could be
disabling some other completely different and important feature of the
