Auto Growing Textareas 介绍

This plugin makes it easy to have auto-growing textareas. Meaning, if you have
a textarea, as the user types it will expand vertically to accommodate the
size of the entry. This was inspired by Facebook’s auto-expanding text areas.

To make a textarea autogrow, simply do this

$(‘textarea’).autogrow();
$(‘textarea.classname’).autogrow();
etc…
