Syntax

onkeypress="script"

Description

The onkeypress event handler captures a completed key-press-and-release sequence (equivalent to onkeydown followed by onkeyup) while the element to which the attribute is applied has focus.

Example

In the example below, the onkeypress attribute triggers a piece of JavaScript that runs some kind of availability check, such as one to ensure that as each letter is typed, the user is provided with feedback.

<input type="text" onkeypress="checkAvailability();"  name="domain_name"
    id="domain_name"/>

Value

This attribute has no fixed value. It’s up to the author to decide on the scripting that’s included here, be that a call to one or more defined functions, or a simple alert() statement.
