// With event call functions to Stop or Start the scroll
// and to change the direction between scroll left and right.
// The images or HTML content, and optional links may specified in an array
// or within HTML Coded <DIV>s
// The images or HTML content width and scroll speed are specified in the initialisation call.
// Optionally the Default
// width, height, background color, text color, text align, and font size
// may be assigned for each element in the array.
//
// There may be as many independent application as required on a page

// Application Notes

// **** The HTML Code
//
// The Banner parent is defined in the HTML code
// e.g.
// If the content is defined in an array
// <div id="fred1" style="position:relative;overflow:hidden;width:1200px;height:100px;border:solid black 1px;"
// onmouseover="zxcBannerStop(event);"
// onmouseout="zxcBannerStart(event);"
//  >
// </div>
//
// If the content is defined in within HTML Coded <DIV>s
// <div id="fred4" style="position:absolute;overflow:hidden;left:210px;top:225px;width:90px;height:100px;border:solid black 1px;text-align:center;"
// onmouseover="zxcBannerStop('fred4');"
// onmouseout="zxcBannerStart('fred4');"
// >
//  <div>
//   testing testing0 <br>
//   testing testing1 <br>
//   testing testing2 <br>
//   testing testing3 <br>
//   ........
//  </div>
// </div>
//
// This <DIV> must be assigned a unique ID name
// and must be assigned style attributes of 'position:relative;overflow:hidden;'
//
//


// **** The Content Array
//
// The Content Array defines each element of the banner in a field dimensioned array
// e.g.
// Field 0 defines a common directory path to the images, use '' if not required
// var ContentAry=['http://www.vicsjavascripts.org.uk/StdImages/']
//
// Subsequent fields are arrays defining the content data
//                type, content,               link url, width, height, bgcol,    txtcol,   txtalign, fontsize
//                0     1                      2         3      4       5         6         7         8
// ContentAry[1]=['TXT','Some Text to Display',''       ,''    ,''     ,'#FFCC66','#9966FF','center' ,'13px'];
// ContentAry[2]=['IMG','Zero.gif','',100  ,80   ,];
//
// Fields 0 and 1 are mandatory
// Fields 2 to 8 may be null(omitted if last) or assigned '' to use the defaults.
// Elements with link urls assigned are also assigned with a cursor 'hand' or 'pointer'
// Note:
// see  ****  External Function)


// **** Initialisation
//
// Each Banner must be initialised from a <BODY> or window onload event
// e.g.
// <body onload="zxcCSBanner('fred1',ImgPath,ContentAry,200,50);zxcCSBanner('fred2',ImgPath,ContentAry,200);" >
// where 'zxcCSBanner(' parameters are:
// parameter 0 = the unique ID name of the Banner <DIV>                       (string)
// parameter 1 = the type of banner 'H' = horizontal, 'V' = vertical.         (string, 'H' or 'V')
// parameter 2 = (optional) the default width of each element.                (digits or null)
// parameter 3 = (optional) the scroll speed (1 = fast, 500 = slow).          (digits or null)
// parameter 4 = (optional) the Content Array name.                           (array variable name, or omit)
//
// Optional parameters may be omitted from the right.
//


// **** Start Scroll
//
// The event call to start the scroll is
// from an external call <input type="button" name="" value="Start" onclick="zxcBannerStart('fred1',1);">
// or onmouseout="zxcBannerStart('fred1');"
//
// where
// parameter 0 = the unique ID name of the Banner <DIV> (string)
// parameter 1 = (optional) the scroll direction        (1 = right, -1 = left) (digits, 1 or -1)
//


// **** Stop  Scroll
//
// The event call to stop the scroll is
// <input type="button" name="" value="Stop" onclick="zxcBannerStop('fred1');">
// or  onmouseout="zxcBannerStop('fred1');"
//
// where
// parameter 0 = the unique ID name of the Banner <DIV> (string)
//
// **** Changing Direction
//
// The Scroll Direction may be changed by calling function 'zxcCngDirection('
// e.g.
//  <input type="button" name="" value="Left" onclick="zxcCngDirection('fred1',-1)">
//  <input type="button" name="" value="Toggle" onclick="zxcCngDirection('fred1')">
//  <input type="button" name="" value="Right" onclick="zxcCngDirection('fred1',1)">
// where 'zxcCngDirection(' parameters are:
// parameter 0 = the unique ID name of the Banner <DIV>                           (string)
// parameter 2 = the scroll direction (1 = right, -1 = left, omit or 0 = toggle) (digits, 1, 0, -1 or omit)



// ****  External Function (Array Applications)
//
// The Default action when a link url is clicked is to replace the current window with the specified url.
// The Function 'zxcExternal' is provided for other requirements.
// To access this function the url field must include the character '^|^'
// Clicking the frame will now call function 'zxcExternal' passing the url text to the function.
// This test may now be split using var zxcdata=zxcfun.split('|'); and the split fields used
// to meet the specific requirement


function zxcExternal(zxcfun){
// Example to call a function where the obj.url(field 2 of the array) is 'FunctionName^|^functionparameter'
// function 'FunctionName' will be called passing 'functionparameter' as a parameter
 var zxcdata=zxcfun.split('^|^');
 window[zxcdata[0]](zxcdata[1]);
}


// **** General
//
// All variable, function etc. names are prefixed with 'zxc' to minimise conflicts with other JavaScripts
// These character are easily changed to characters of choice using global find and replace.
//
// The Functional Code(about (4.75K) is best as an External JavaScript
//
// Tested with IE6 and Mozilla FireFox
//


// **** Customising Variables
/*
var zxcBGColor='#FFFFCC';   // The default background color of banner elements (string)
var zxcTxtColor='black';      // The default text color of banner elements (string)
var zxcTxtAlign='center';   // The default text alignment of banner elements (string)
var zxcFontSize='22px';     // The default font size of banner elements (string)
*/
