Safari (Mac) - keysuppress(event) issue

[Marcia Gulesian]

The following code suppresses the 'enter' key, when run in I.E. 5.5 or
later (Windows) but not when run in Safari (Mac)

<body onkeypress="jav ascript:keysupp ress(event)" >

function keysuppress(e)
{
if (e.type=="keypr ess" && e.keyCode=="13" )
{
event.returnVal ue=false
}
}

What code can I use to suppress the 'enter' key when running an app in
Safari?

Thanks.

I don't have Safari here to test but the following hopefully works as it
uses both the W3C DOM Level 2 event handling preventDefault method and
the established return false to cancel the keypress event:

<html lang="en">
<head>
<title>keypre ss event handling</title>
<script type="text/javascript">
function init () {
document.onkeyp ress = function (evt) {
if (!evt && window.event) {
evt = window.event;
}
if (evt) {
var keyCode = evt.keyCode ? evt.keyCode :
evt.charCode ? evt.charCode : evt.which;
if (keyCode == 13) {
if (evt.preventDef ault) {
evt.preventDefa ult();
}
return false;
}
else {
return true;
}
}
return true;
};
if (document.layer s) {
document.captur eEvents(Event.K EYPRESS);
}
}

init();
</script>
</head>
<body>
<form action="">
<p>
You should not be able to enter line breaks if the keypress event handling
works:
<br>
<textarea name="textareaN ame" rows="5" cols="80"[color=blue]
>Kibology for all.[/color]
</textarea>
</p>
</form>
</body>
</html>

Tested to work in IE 6, Netscape 7.1, Mozilla 1.7, Netscape 4.
Please report back to the group whether that solves the problem for Safari.

Doesn't work in Safari 1.0.2, no errors.
