[JS] Need Help Removing File extension (in CS2 and CS3)

Question

Hello All.
I have a menu in a dialog that needs to list some file names, but without their file extensions (which will always be .txt in my case). The following is some code that successfully does this in CS3, but I also need it to work in CS2. Do you have any other ways to do this? One code that works in both versions (CS2 and CS3) is ideal.
myNameWithoutExtensionFunction = function( myNameWithExtention ) {
myNameWithoutExtension = myNameWithExtention
myEndOfFileName = myNameWithoutExtension.lastIndexOf( "." )   // get the last period (.) in the filename
if ( myEndOfFileName > -1 ) {
  myNameWithoutExtension = myNameWithoutExtension.substr( 0, myEndOfFileName )
return myNameWithoutExtension
Thanks in advance.

I realized my mistake. The above code works just fine in CS2. My mistake was elsewhere. The name I was sending to this function wasn't being recognized by CS2. Once I corrected that and sent a valid name to this function it worked. So in case someone needs to remove file extensions, feel free to use the above function!
