Question

IE version 8

The regex is working fine in firefox:

filename variable contains: testfile.arv (see invalid extension)

if (/\.(doc|xls|ppt|eml|txt|pdf|rtf).?\b/i.test(filename)) {
...
}

in IE it simply passes out as valid name.

EDIT:
After I changed the expression as suggested below. it continued to fail – in IE only. made me realize that it is not about this expression but something about IE and the javascript module I am using to do this.

I am using http://malsup.com/jquery/form/ this form plugin to upload multiple files. this is working properly on firefox, but is not working on internet explorer. it just simply uploads everything and does not show upload progress etc.

since this problem is turning out to be different I will close this thread and submit new question.

Thx for everyone’s time and sorry for trouble. I am finding this porting thing a little difficult (from firefox to IE)

Answer 1

try ending it with an “$”, like so

if (/\.(doc|xls|ppt|eml|txt|pdf|rtf)$/i.test(filename)) {
  // super awesome code
}
