A jQuery numerical slider that follows a bezier path.

Features

• Numerical slider similar to the jQuery UI Slider - currently it only works with percentages (0-100%)
• This slider follows a bezier path. The parameters are set using the pathslider builder.
• Designed to work in older browsers (no canvas support), just add the path as a background image.
• Get and set the slider position dynamically.
• Slider handle (grip) can be set to rotate along with the angle of the curve (uses css3).
• Callback events are available: create, update, start, slide, change, and stop.
• The slider itself works in all browsers: IE6+, Opera, Chrome, Firefox and Safari (known issues below)
• Pathslider demo.
• Pathslider Builder.

To Do:

• Add min, max and step options to use values, other than zero to one hundred percent, with the slider.
• Add enable, disable, destroy methods.
• Smooth out sliding by improving grip position calculation
  • The grip jumps around quite a bit with some settings
  • This can be minimized by adjusting the tolerance & range settings, but it needs a better method.
• Add more default handle (grip) styles in the css.
• Add ability to make a gradient/patterned stroke style of the curve; I'm not sure it will follow the path of the curve or just be a static background. Needs more testing!
• Add keyboard control to the slider when it has focus - arrows, page up/down, home and end.
• Add a circular path
  • I don't plan on making it go continuously around in a circle. It will have a starting and stopping point.
  • If you need a continuous circle slider, check out this one, and this one.
• Combine multiple beziers to make extended shapes - my math skills are a bit lacking so this may take a while, unless someone out there is willing to help ;)
• Consider switching from using canvas to svg.

Dependencies

• jQuery 1.4.4+
• A browser that supports canvas (needed for the builder; optional for the pathslider plugin itself).
• A browser that supports css3 transforms (necessary to rotate the grip).

Known Bugs

• The grip/handle will work if the loop folds back on itself - try these points to see an example: 75,200,200,-125,-200,0,225,200
• The S-Curve demo seems to get stuck near 100% but only in Firefox and on the demo page. It works fine when isolated. The grip isn't staying centered under the cursor like it does in Chrome.
• Safari for Windows likes to start with the grip in the upper left corner of the slider box... most of the time when I hover over it, it jumps to where it should be... wow that is so weird. Also, the "S" curve demo doesn't want to work at all...
