Function to determine file type

Question

I am looking for a basic function that will receive a string,
I want the function to look at the string and determine what the
file type is, then perform another function.
where filename = "demo.swf" or "somethingElse.pdf"
if filename == 'swf'
goto "10"
else if filename == 'pdf'
goto "20"

Answer 1

You can use the String.split() method, to split the file name
at the period.
Then the file type will be the second item in the array:
function getExtension (fileName:String):String {
return fileName.split(".")[1];
