Json string to Array (js, jQuery)

Question

I have the following string in my jquery function:

{"rows":[{"id_sala":"27","horas":"4","Fecha":"2014-05-05"},{"id_sala":"27","horas":"5","Fecha":"2015-04-30"}]}

and I need to convert this into an array for use it in google charts, i have tried to program my own function but I had a really bad headhache.

Any help will be appreciated.

Use the function JSON.parse() and then you'll need to iterate over it with loops. — evolutionxbox

$.parseJSON( jsonString ) if you have the JSON string in jQuery JSON.parse( jsonString ) if you have the JSON string in a browser — detheridge02

@evolutionxbox @detheridge02 that was my first option, but when I pass the resulting arr to the google method it sais Uncaught Error: Argument given to addRows must be either a number or an array — ivan

Parsing of the jsonString gives you a json object like this. Object {rows: Array[2]}. Since you need an array of rows to be passed to the addRows method, you have to code as shown below.

String jsonString ='{"rows":[{"id_sala":"27","horas":"4","Fecha":"2014-05-05"},{"id_sala":"27","horas":"5","Fecha":"2015-04-30"}]}';
var rows=  JSON.parse(jsonString).rows; //Returns an array of rows
//Pass rows to the addRows method.
