javascript - FineUploader allowedExtensions use an array? -

i'm using fineuploader v3.8, , have gotten , running. @ point, i'm listing available file types user in html, , there's reference these in configuration. wanted have 1 place extensions listed there's no duplication, , can changed.

i tried this:

var allowedextensions = new array('jpg', 'gif', 'png');

var allowedextensions = "'jpg', 'gif', 'png'";

and within 'validation:' used this:

allowedextensions: [allowedextensions],

this doesn't work, , invalid file type messagebox any/all file types.
there way utilize array variable in javascript of control configuration? thanks!

with 1st , 3rd snippet, you're creating array containing array

it needs either array literal ([...]) or new array(...) rather both.

var allowedextensions = ['jpg', 'gif', 'png']; 

allowedextensions: allowedextensions, // no brackets
