12.3.3.1. Standard event handler attributes
Table 12-1
presents the current set of event handlers as tag attributes.
Most are supported by the popular browsers, which also support a vari-
ety of nonstandard event handlers (tagged with asterisks in the table).
We put the event handlers into two categories: user related and docu-
ment related. The user-related ones are the mouse and keyboard events
that occur when the user handles either device on the computer. User-
related events are quite ubiquitous, appearing as standard attributes in
nearly all the standard tags (even though they may not yet be suppor-
ted by any browser), so we don't list their associated tags in
Table 12-1
.
Instead, we'll tell you which tags
do not
accept these event attributes:
