Covert form data to JSON string

Question

If I

Answer 1

if you get this

[{"name":"login","value":"a value"},{"name":"email","value":"a email"}];

and you need just

{"name":"login","value":"a value"}

just call the variable by their index

var data = [{"name":"login","value":"a value"},{"name":"email","value":"a email"}];

console.log( data[0] )
