Having an array 

```
`Array
(
    [0] => Array
        (
            [operative] => 2
            [start] =>  01:00:00
            [end] =>  13:00:00
            [color] => 543939
        )

    [1] => Array
        (
            [operative] => 3
            [start] =>  08:00:00
            [end] =>  09:00:00
            [color] => 52e612
        )

)

`

```

need to change this into JSON so I use json\_encode(), I get a string   
`[{"operative":"2","start":" 01:00:00","end":" 13:00:00","color":"543939"},{"operative":"3","start":" 08:00:00","end":" 09:00:00","color":"52e612"}]`

but when I am using JSON into JavaScript by function $.parseJSON() or JSON.parse(), both are giving me not defined.

ok I have used it like this 

```
options1 = '[{"operative":"2","start":" 01:00:00","end":" 13:00:00","color":"543939"},{"operative":"3","start":" 08:00:00","end":" 09:00:00","color":"52e612"}]'
options1 = $.parseJSON(options1);
alert($.param(options1));

```

But alert is showing me undefined=&undefined=
