|
|
* Originally written by George Adamson, Software Unity (george.jquery@softwareunity.com) August 2006.
|
|
* - Added min/max options

|
|
* - Allow limited or unlimited min/max values
|
|
* - Allow custom class names, and add class to input element
|
|
* - Removed global vars
|
|
* - Reset (to original or through config) when invalid value entered
|
|
* - Repeat whilst holding mouse button down (with initial pause, like keyboard repeat)
|
|

spinClass: mySpinBtnClass, // CSS class to style the spinbutton. (Class also specifies url of the up/down button image.)

|
upClass: mySpinUpClass, // CSS class for style when mouse over up button.
