Hi,
=20
I am trying to get a handle on the netWindows event model, which looks
very good. So I tried to modify netWindows 0.3.0
/docs/widget_test_pages/multi_line_eval.html to pop up an alert for the
textarea onkeyup event, as shown in the code below. But it doesn't
work: mytest() is never called. Can anyone please explain what I am
doing wrong?
=20
<script language=3D"JavaScript">
//widget includes
=20
__scripts__.require(__config__.widgetPath+"text_expander_widget.js");
=20
__scripts__.require(__config__.widgetPath+"button_widget.js");
=20
function mytest() {
alert( "mytest()" );
}
=20
function envInit(){
create_console('<<debugging console initialized>>', 0, 0,
'right', 'top', 400, 300, 100);
=20
var ta =3D document.getElementById( "eval_code" );
if( ta !=3D null ) {
alert( "setting handler" );
__sig__.connect( ta, onkeyup, null, mytest );
} else {
alert( "can't find ta" );
}
}
__sig__.connect(__env__, __env__.onLoad, null, envInit);
=20
</script>

Thanks,
