[Javascript] Trapping keys with NS 6

Sat Jan 12 04:27:10 CST 2002

Hi,

I want to trap (and inhibit) various keys, such as * in a form text field.  The following code works fine in IE 5 and NS 4 (both Mac and Win), but not correctly in NS 6.  In NS 6 (again both Mac and Win versions), the * gets inserted into the field, and THEN the alert message comes up!

Any ideas of how to cope with this? Is there a new version of captureEvents that has to be set?

Many thanks,

John
