# Textarea.onchange() Handler

## Name

Textarea.onchange() Handler---invoked when input value changes

## Availability

Navigator 2.0, Internet Explorer 3.0

## Synopsis

    <TEXTAREA
          onchange="handler-statements" ...>   a definition of the handler
    </TEXTAREA>
    textarea.onchange a reference to the handler
    textarea.onchange();  an explicit invocation of the handler

## Description

The `Textarea.onchange()` event handler is defined by the `onChange` attribute of the `<TEXTAREA>` HTML tag that defines the Textarea object. The value of this attribute may be any number of JavaScript statements, separated by semicolons; these statements will be executed whenever the user changes the value in the Textarea and then "commits" those changes by moving keyboard focus elsewhere (i.e., by clicking the mouse elsewhere or by typing the Tab or Return keys). This handler is intended to process a complete change to the input value, and therefore is not invoked on a keystroke-by-keystroke basis. Also, note that the `onchange()` event hander is not invoked when the `value` property of a Textarea object is set by JavaScript.
