From the developer: "Standard HTML control set is lacking Spin control. yCode Spin is just like a regular Windows Spin box, but is implemented entirely in JavaScript/DHTML. It consists of a pair of arrows that user can click to increment or decrement a value displayed in a companion text control; user can also type in a value into text control directly. Full documentation and complete source code is available with purchase."

Note: Demo code is scrambled. Full documentation and 'complete' source code is available with purchase.
