Javascript post array and receive it in serverside

Question

I'm trying to send array using ajax, imagine the array

var anotherOne = 'anotherOneData';
var documents = ['banana', 'apple', 'monkey'];

I sent these normal value and array to server-side, using ajax, no problem with got this in server side,

console.log(req.body);

//result (anotherOne is I sent too, this is not array,)
{ anotherOne : 'anotherOneData',
  'documents[]': 
[ 'banana', 
'apple, 
'monkey' ] }

How can I access documents's first element?

req.body.documents[0] // not working
req.body.documents[0][0] // not working
req.body.documents instanceof Array // false : why?

I'm totally couldn't get what's going on, Please help me.

Could you post the code you're using to submit the AJAX call? — rkd

Based on what you've logged, the property on req.body is called documents[], so:

console.log(req.body['documents[]'][0]);

That said, I think I'd send it as JSON and then parse it on the server.
