This is a jquery plugin that will auto-grow your text areas vertically (like facebook) or horizontally. It is based off a code snippet by dhruvbird. The plugin uses a hidden mirror textarea to calculate the idea height (and width) of the target text area. Differences from the original code snippet are:

  • Support for horizontal auto-growth of text areas. That is, text areas that expand horizontally as you type.
  • Once the plugin has been activated on a textarea, the textarea will listen for the custom "remove.autogrow" event. If that event is triggered, the plugin will clean up the resources that is uses to avoid memory leaks. (Specifcally, the mirror textarea used by the plugin will be removed from the DOM.)


$( "textarea" ).autogrow();

or for horizontal growth only:

$( "textarea" ).autogrow( { vertical : false, horizontal : true } );

or for both (untested? I can't remember!)

$( "textarea" ).autogrow( { vertical : true, horizontal : true } );

To cleanup before removing original textarea element from DOM, or after plugin is no longer needed:

$( "textarea" ).trigger( "remove.autogrow" );
Something went wrong with that request. Please try again.
