* FlashSwapper
* JavaScript Object that puts a Flash movie into your HTML if it is supported.
* By Isaac Z. Schlueter
*
* Send it the ID of an HTML element (div or something) that contains the back-up contents by default.
* Then, call the Swap() method, and it'll replace it.
*
* This flash detection/swapping object is liberally based on the Moock FPI
* http://www.moock.org/webdesign/flash/detection/moockfpi/
* and an article on the Frobnosticatorium
* http://www.apeiros.com/frob/tech/detect/
*
* Thanks, Guys.

*
* USAGE:
*
* You can set all the variables in the constructor, and then call the Swap() method.
*
window.onload = function() {
var Flasher = new FlashSwapper(
6, //version - version of flash required, required
'myMovie.swf', // fileName - the flash movie filename, required
'myContainerID', //containerId - the ID of the element that we'll be swapping out, required.
'myMovieName', //id - the id of the movie itself, optional.
123, //width - movie width, optional
123, //height - movie height, optional
'high', //quality - movie quality, optional (low|medium|high)
'opaque', //wmode - window mode, optional (window|opaque|transparent), requires at least version 6.
'over'|'after'|'before' //swapMethod - whether or not it'll remove the container's innerHTML on swapping or be placed before or after it. optional, default=over
);
Flasher.Swap();
}
*
* You may of course also set any of those properties after calling the constructor, as long as all the
* required ones are set before you call Swap(), using LoadContainer to grab the container element, like so:
*
window.onload = function() {
var Flasher = new FlashSwapper();
Flasher.requiredVersion = 6;
Flasher.fileName = 'myMovie.swf';
Flasher.id = 'myMovieName';
Flasher.width = 123;
Flasher.LoadContainer('myContainerID');
Flasher.height = 123;
Flasher.wmode = 'opaque';
Flasher.quality = 'high';
Flasher.Swap();
}
*
* If the swap fails, it'll return false, and the errors var will be set to the reason why.
* In debugging, you might want to do this:
*
window.onload = function() {
var Flasher = new FlashSwapper();
Flasher.requiredVersion = 6;
Flasher.fileName = 'myMovie.swf';
Flasher.id = 'myMovieName';
Flasher.width = 123;
Flasher.height = 123;
if(!Flasher.Swap())alert(Flasher.errors); // in this case, it would be because you didn't give it a container
}
*
* To simply detect for a certain version, and not automatically swap, you may use the HasVersion() method.
* Either send it a version number, or set the .requiredVersion property first.
*
window.onload = function() {
var Flasher = new FlashSwapper();
if(Flasher.HasVersion(6)) {
// the user has flash version 6 or higher
} else if(Flasher.HasVersion(5)) {
// the user has version 5 or higher
} else if(Flasher.HasFlash) {
// the user has flash, but less than version 5
} else {
// no flash at all.
}
}
