I used the jQuery UI slider component in my page to set a range of prices. I can also use their ui.values[] to set and show the new values in other divs.
change => This event is triggered on slide stop, or if the value is changed programmatically (by the value method). Takes arguments event and ui. Use event.originalEvent to detect whether the value changed by mouse, keyboard, or programmatically. Use ui.value (single-handled sliders) to obtain the value of the current handle, $(this).slider('values', index) to get another handle's value.
