jquery-autoexpand

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).
