jquery-autoexpand

A textarea will automatically grow and shrink in height as you add or remove content to it.

• The textarea will never shrink smaller than its original height
• The textarea will never grow beyong the bottom edge of the window. Instead, a scroll bar show up in the textarea as more text as added to the textarea.

Usage

$('textarea').autoExpand();

Or if you want to customize some of the options:

$('textarea').autoExpand({ animationTime: 0, windowPadding: 100 });

Remove

If you no longer need the textarea to auto-expand and you want to reset it:

$('textarea').autoExpand('destroy');

Options

Options can be passed in as a { key: value } object literal. Available options are:

property	default value	description
animationTime	50	Time in milliseconds to animate to new height
windowPadding	20	Amount of pixels to preserve between textarea & window bottom

You can remove the auto-expander from a textarea by passing 'destroy' (as string, not in an object literal).
