Alan,
You can do something like this:
Add >> onChange="onChangeHandler(this)" << to the Html tag for textbox using
ExtraHtml property in the ND Studio.
Inside >> function onChangeHandler(textBox) <<
textBox.name, textBox.value etc give you the required information.
If you don't like the value entered by the user, after giving an alert
message you can do:
textBox.value = "<whatever>";
textBox.focus();
The value will change and the focus will go back to the textbox.
(All these works perfectly with Netscape. I remember having problems with
IE, and don't know if it works with later versions, nor what standards they
follow as far as JS is concerned).
For reference on JS supported by NS, you can go to:
