Recently I had to implement a dial-control into an html-app. Unexpectedly I couldn't find any library on the web, so I decided to code my own solution.Show Example
The script needs jQuery and has been tested in IE>=6, Fox and Webkit (Chrome/Safari). If you should find something not working properly drop me a line. The image for the slider-button is a base64-Data URI and won't show up in IE6. Though I don't care that much about IE6 these days, the code will work for this browser but users will only see a colored div as slider. If I have some more time I will build a full-fledged jQuery-Plugin. In the meantime you are free to download the source from below. Usage is free, without warranty and you can use it in any way you want, as long as you do not construct nuclear power-plants or cruise-missiles from it.
And while I was at it, I built a Flash-version as special bonus. You can download the source below, please keep in mind that you will need jQuery as well.Download source
