I've refactored stickyWinHTML (see this previous post) a bit more to allow for as many buttons as you like.

Here's a quick code example:

PLAIN TEXTexecute this code
JavaScript:
var simpleLayoutExample = stickyWinHTML('the caption', 'this is the body', {
  width: '400px',
  buttons: [
    {
      text: 'close',
      onClick: function(){alert('closed!')}
    },
    {
      text: 'okey-dokey',
      onClick: function(){alert('ok!')}
    }
  ]
});
$('layoutExample').adopt(simpleLayoutExample);
var simpleLayoutExample = stickyWinHTML('the caption', 'this is the body', {
width: '400px',
buttons: [
{
text: 'close',
onClick: function(){alert('closed!')}
},
{
text: 'okey-dokey',
onClick: function(){alert('ok!')}
}
]
});
$('layoutExample').adopt(simpleLayoutExample);

drag to resize


The buttons array allows for as many buttons as you like. You can see more detail in the wikitorial on this topic.

Note: the old options (closeTxt, onClose, confirmTxt, and onConfirm) are still supported, though deprecated.
