Hi guys
Here's a shorter way to accomplish the same task:
function getSwfObjectVersion(){
return (window.swfobject) ? 2 : (window.SWFObject) ? 1 : false;
}
window.onload = function(){
alert(getSwfObjectVersion());
};
(Demos are online:
http://pipwerks.com/lab/swfobject/version-detection/index.html)
This function works by checking the global window object for the existence
of objects named swfobject and SWFObject. There are three things going on
here:
1. Since we're checking (window.swfobject) and not just (swfobject), the
browser won't throw a "swfobject is undefined" error if swfobject isn't
found. This means no need for the !== null syntax.
2. Since JavaScript is case-sensitive, two objects with the same name but
different case will appear as two unique objects. SWFObject 1.x was written
with uppercase SWFO, while SWFObject 2.x is written with all lowercase
letters.
3. In the event both versions are found, the function returns SWFObject 2,
which is the preferred version.
Hope you like. :)
