How to parse JSON in JavaScript

I get a string like this

 [["1","Pagamento de Placa","N","N"], ["2,""Contrato","N","N"], ["3","Ajuste de preço","N","N"],["4", "Abertura de cliente","N","N"], ["9","Outros","N","S"]]

I try

 var arr = new Array([["1","Pagamento de Placa","N","N"], ["2,""Contrato","N","N"], ["3","Ajuste de preço","N","N"],["4", "Abertura de cliente","N","N"], ["9","Outros","N","S"]]);

but not work

I want to turn into a real array, any idea how to do?

Thanks

You mean, the whole line is a string? – ATOzTOA Feb 04 '13 at 13:59 — ATOzTOA, Feb 04 '13 at 13:59
JSON.parse() should do that for you. – Ja͢ck Feb 04 '13 at 13:59 — Ja͢ck, Feb 04 '13 at 13:59
yes, the line is string – Daniel Lemes Feb 05 '13 at 14:59 — Daniel Lemes, Feb 05 '13 at 14:59

Use JSON.parse:

var arrayString = '[["1","Pagamento de Placa","N","N"], ["2,"Contrato","N","N"], ["3","Ajuste de preço","N","N"],["4", "Abertura de cliente","N","N"], ["9","Outros","N","S"]]';
var array = JSON.parse(arrayString);

(There's a duplicate " in the original string - I removed it.)

If you need to support older browsers use a library like json2.js or jQuery.parseJSON.

The first element of the second element of the parent array is missing a quote or has one too many. – James Sumners Feb 04 '13 at 14:03
