A lightweight Javascript Library for automatic direction change of input between rtl and ltr based on character count.

HTML5 dir="auto" attribution is good, but it just depends on first character in most browsers ,that is not functional on most arabic and persian web applications.

Demo link

Include automatic-direction.js in bottom of the page before body close tag

<script src="js/automatic-direction.js"></script>

add .dir-auto class to input that you want to automate direction on it

<textarea class="dir-auto" ></textarea>
