// 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.
//

// **** Advanced Applications
//
//  Calling function 'zxcBAnimator' returns the instance of the script,
//  this may be assigned to a variable and used to access the current value of the effect or to control the effect.
//  alternatively the script instance by elementobject[mode.replace(/\W/g,'')+'oop'];
//  where mode is parameter 0 of the initial call.
//  An array storing the current, start and finish values of the element effect may be accessed
//  from the element [instance].data as fields 0, 1 and 2 respectively where [instance] is the instance of the script.
//
//  Once initialised the effect may be updated by calling function
//  [instance].update([100,200])
//  where:
//   parameter 0 = an array defining the start and finish values.                                            (array)
//                  field[0] =the start position of the effect.   (digits, for opacity minimum 0, maximum 100)
//                  field[0] = the finish position of the effect. (digits, for opacity minimum 0, maximum 100)
//   parameter 1 = (optional) period of time between the start and finish of the effect in milliseconds.     (digits or defaults to 2000 milliSeconds)
//   parameter 2 = (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 3 = (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.
//
// ** Bounce
//   A 'bounce' effect may be applied by assigning the script instance property 'Bounce' an array
//   defining the 'bounce' properties.
//   e.g.
//   [instance].Bounce=[100,90,4,200];
//   where:
//    field[0] = the 'bounce' maximum.  (digits)
//    field[1] = the 'bounce' minimum.  (digits)
//    field[2] = the number of bounces. (digits)
//    field[3] = the 'bounce' duration. (digits)
//


// **** General
//
// Function names are prefixed with 'zxc' to minimise conflicts with other JavaScripts.
// These characters may be changed to characters of choice using global find and replace.
//
// The Functional Code, about 2.41K with 'bounce' and 'opacity' or 1.97K without is best as an External JavaScript.
//
// Tested with IE7 and Mozilla FireFox on a PC.
//

// **** Functional Code - NO NEED to Change

**Roger1941** · 08-02-2009, 10:58 AM

Hi Vic. Many thanks for your reply, I have tried it but not quite what I am looking for.

To explain more clearly what I am looking for:-

Could you maybe take a look at www.ownersdirectspain.org/tajsell.htm . On mouse over the images individually enlarge. But its all very abrupt in presentation and I am looking to have the enlarged images fade in and out slowly.

Regards

Roger

Hi again Vic.

Have been looking at your web site, http://www.vicsjavascripts.org.uk/Im...?1249212588109 this script looks perfect for what I want to achieve.

Problem is that having copied and pasted it into Frontpage I cannot get it to run. I am clearly doing something (or more likely many) things wrong.

Does part of the script go in the <head> and part in the <body>? Grateful for any help you can give.

Regards

Roger

**vwphillips** · 08-02-2009, 01:30 PM

the script would normally be positioned in the <HEAD></HEAD> tags

or immediately before the </BODY> tag

also see

http://www.vicsjavascripts.org.uk/El...MoveExpand.htm

**Roger1941** · 08-02-2009, 04:09 PM

Hi Vic
Very many thanks for all your help. The last script is just that I was looking for. I am at the moment working on www.amateur-painting.org, but will use your script on www.ownersdirectspain.org also if that is OK with you?

More help if you dont mind! Maybe you could take a look at :-
http://www.amateur-painting.org/new_page_3.htm Is it possible to include a description of the enlarged images?.

Regards

Roger

**vwphillips** · 08-03-2009, 10:32 AM

but will use your script

Hi again Vic

And again many thanks, beginning to wander if you ever have time for paid work!

Got a problem with this one. Copied , pasted and uploaded at:-

I am clearly doing something wrong, only source being displayed
