noUiSlider is a little jQuery plugin that makes really cool (double) range sliders. Every slider can have two handles to select a range, a fixed minimum or maximum can be set to select a limit, or two handles can be used, to simply pick some points.
Supports Google Chrome, Firefox, Opera, Safari and Internet Explorer 7 to 10. It also supports touch on capable devices, such as iPhone, iPad and Android phones and tablets.
Every event in the noUiSlider has an optional callback, so you can completely control any slider interaction. There is also some cool math in the read-out functions, so you can dynamically calculate any selected value.
