Example
In the example below, the
onkeypress attribute triggers a piece of JavaScript
that runs some kind of availability check, such that as each letter is
typed the user may be provided with feedback.
<input type="text" onkeypress="checkAvailability();" name="domain_name" id="domain_name" />
Description
The
onkeypress event handler captures a completed key
press and release sequence (equivalent to onkeydown followed by
onkeyup) while the
element that the attribute applied to has focus.
Value
There is no fixed value - it is up to
the author/developer what scripting goes in here, be that a call to one or
more defined functions or a simple alert() statement.
