// Basic Element Animator (14-May-2009)
// by Vic Phillips http://www.vicsjavascripts.org.uk
// To progressively change the Left, Top, Width, Height or Opacity of an element over a specified period of time.
// With the ability to scale the effect time on specified minimum/maximum values
// and with three types of progression 'sin' and 'cos' and liner and an optional 'Bounce'.
// **** Application Notes
// **** The HTML Code
//
// when moving an element the inline or class rule style position of the element should be assigned as
// 'position:relative;' or 'position:absolute;'.
//
// The element would normally be assigned a unique ID name.
//
// **** Executing the Effect(Script)
//
// The effect is executed by an event call to function 'zxcBAnimator('width#',document.getElementById('tst'),10,800,5000,[10,800],'sin');'
// where:
// parameter 0 = the mode(see Note 2). (string)
// parameter 1 = the unique ID name or element object. (string or element object)
// parameter 2 = the start position of the effect. (digits, for opacity minimum 0, maximum 100)
// parameter 3 = the finish position of the effect. (digits, for opacity minimum 0, maximum 100)
// parameter 4 = (optional) period of time between the start and finish of the effect in milliseconds. (digits or defaults to 2000 milliSeconds)
// parameter 5 = (optional) to scale the effect time on a specified minimum/maximum. (array, see Note 5)
// field 0 the minimum. (digits)
// field 1 the maximum. (digits)
// parameter 6 = (optional) the type of progression, 'sin', 'cos' or 'liner'. (string, default = 'liner')
// 'sin' progression starts fast and ends slow.
// 'cos' progression starts slow and ends fast.
//
// Note 1: The default units(excepting opacity) are 'px'.
// Note 2: Examples modes: 'left', 'top', 'width', 'height', 'opacity.
// For hyphenated modes, the first character after the hyphen must be upper case, all others lower case.
// Note 3: To 'toggle' the effect include '#' in parameter 0.
// The first call will set the toggle parameters.
// Subsequent calls with '#' in parameter 0 and the same start and finish parameters will 'toggle' the effect.
// Note 4: The function may be re-executed with a different set of parameters (start/finish time or period)
// whenever required, say from an onclick/mouseover/out event.
// The period parameter will be retained unless re-specified.
// Note 5: parameter 5 is of particular use when re-calling the effect
// in mid travel to retain an constant rate of progression.
// Note 6: parameters 2 and 3 must be different values to execute the script.
//
// **** Functional Code - NO NEED to Change
