I need a good way to isolate the last 4 letters of a string (file extension) any ideas? nothing I try seems to work...

this should manage it

Code:

tempstr = "testing.swf";
tempext = tempstr.slice(tempstr.length - 4, tempstr.length);
trace(tempext); //will give you ".swf"

or if you're not sure how long the extension is going to be

Code:

tempext = tempstr.slice(tempstr.lastIndexOf("."), tempstr.length);
