SimpleSlider is a jQuery plugin for turning your text inputs into draggable numerical sliders.

It has no external dependencies other than jQuery, and you don't need to write a single line of JavaScript to get it to work.

Include the javascript file in your page:

<script src="simple-slider.js"></script>

Turn your text input into a slider:

<input type="text" data-slider="true">
