/*
|
||||
Styles to make ordinary <INPUT type="text"/> look like a spinbutton/spinbox control.
|
||||
Use with JQuerySpinBtn.js to provide the spin functionality by reacting to mouse etc.
|
||||
(Requires a reference to the JQuery library found at http://jquery.com/src/latest/)
|
||||
(Hats-off to John Resig for creating the excellent JQuery library. It is fab.)
|
||||
|
||||
This control is achieved with no extra html markup whatsoever and uses unobtrusive javascript.

Do contact me with comments and suggestions but please don't ask for support.
|
||||
As much as I'd love to help with specific problems I have plenty to get on with already!
|
||||
|
||||
Go ahead and use it in your own projects. This code is provided 'as is'.
|
||||
Sure I've tested in heaps of ways. Its good for me, but you use it at your own risk.
|
||||
SoftwareUnity and I are certainly not responsible if your computer sets fire to the sofa,
|
||||
hacks into the pentagon, hijacks a plane or gives you any kind of hassle whatsoever.
|
||||
|
||||
If you'd like your spin-button image in a different place then you'll need to alter both
|
||||
the CSS below and the javascript isMouseOverUpDn() function to accommodate the new position.
|
||||
You could even have left and right buttons either side of the textbox.
