Well first you need to extract the filename from addfile after its added, like as mentioned here: Javascript - How to extract filename from a file input control

and then use that inside filetype.

  • hi Mrchief the code gives me file name like new.txt, file.xml , what to add to have only extension like .txt, .xml – michael Jul 22 '11 at 14:29
  • Try this: `var ext = filename.split('.')[1]; // filename.split('.')[0] will be jsut the name` – Mrchief Jul 22 '11 at 14:32
  • i tried like this while (fullPath.indexOf("\\") != -1) fullPath = fullPath.slice(file.indexOf("\\") + 1); ext = fullPath.slice(fullPath.indexOf(".")).toLowerCase(); it also wrkd ,thanks mrchief – michael Jul 22 '11 at 14:38
  • Yeah, that'd work too. I just prefer `split` as it is shorter and cleaner and doesn't make calculate those pesky indexes. – Mrchief Jul 22 '11 at 14:43
