How can I disable the Tab and Enter Key?

Hi Experts,

How can I disable the Tab and Enter Key?

Thanks

add a key 'listener'

function myKeyListener(event) {
if (!event) {
            event = window.event;
      }
      //alert (event.keyCode);

      if (event.keyCode == 13) {
            // enter key - do nothing
      }
// add one for the tab key
}

then add this function to the onkeydown event for the page/textbox/etc
https://www.experts-exchange.com/questions/21382788/onkeydown-event-Firefox.html tries something similar

Is it possible to disable these keys onload of the "default.asp" page rather than onkeydown?

Thanks

kawas

on the onload event, you would have to add the function so that onkeydown of whatever item you want the keys disabled

ASKER

So this function is only fired when the user types?

kawas

yes

I want to fire the function on load of the "default.asp" page.

Can you provide more specific code for this? I am sorry but I am not very good at Java script.

Thanks

kawas

Steps are:

1. <body onload="init()">

2. define init()

function init() {
document.onkeypress = myKeyListener;
if (document.layers) document.captureEvents(Event.KEYPRESS);
}
function myKeyListener(event) {
if (!event) {
event = window.event;
}
//alert (event.keyCode);

if (event.keyCode == 13) {
// enter key - do nothing
}
// add one for the tab key
}

or a shorter example

@kawas: A bit nonchalant to not kill the event, to leave the tab key as an exercise for the reader and to not handle other browsers than IE

Pravin Asar

Following diables tab and enter key for all fields on page
<script language="javascript">
function keyHandler(e) {
var pK = e ? e.which : window.event.keyCode;
if (pk == 13) { return false; }
if (pk == 9) { return false; }
}

function DisableEnterAndTab () {
if (document.all) // IE
{
document.onkeypress = kH;
}
if (document.layers) {
document.captureEvents(Event.KEYPRESS);
}
}
</script>

<body onload="DisableEnterAndTab();">

Michel Plungjan

Ohh, here is one I never saw before

kawas

that disables on a textfield, not the whole page

@pravinsar :Please test your code. Especially when the asker tells you he is not great at JS - document.all is IE and document.layers is NS4 - what about mozilla and FF?

<script language="javascript">
function kH(e) {
var pK = e ? e.which : window.event.keyCode;
if (pk == 13) { alert('No enter'); return false; }
if (pk == 9) { alert('No tab'); return false; }
}

function DisableEnterAndTab () {
if (document.all) // IE
{
document.onkeypress = kH;
}
if (document.layers) {
document.captureEvents(Event.KEYPRESS);
}
}
</script>

<body onload="DisableEnterAndTab();">
<form onSubmit="alert('No you did not disable them'); return false">
<input type="text" name="t1" value="">
<input type="text" name="t2" value="">
<input type="submit">

</form>

This is what I have:

function init()
{
document.onkeypress = myKeyListener;
if (document.layers) document.captureEvents(Event.KEYPRESS);
}

function myKeyListener(event)
{
if (!event)
{
event = window.event;
}
if (event.keyCode == 13)
{

}
}

I checked out http://www.felgall.com/jstip43.htm

I do not know how to incorporate this. Please be more specific and just provide me with the script.

Thanks

@experts: I do not have time to find the combo I wanted to find.

Please look here and test before presenting

Here is a cool site though. the prototype.js has a lot of cross browser event handling

This is what I have now and it works but only for Enter key:

<SCRIPT Language="JavaScript">
function kH(e)
{
var pK = e ? e.which : window.event.keyCode;
return pK != 13;
}

function DisableEnterAndTab ()
{
if (document.all) // IE
{
document.onkeypress = kH;
}
if (document.layers)
{
document.captureEvents(Event.KEYPRESS);
}
}
</SCRIPT>

How do I incorporate the Tab key?

Thanks

return pK != 13 && pK != 9;
