在jQuery中访问JSON编码的PHP数组

I have an PHP Array which is formatted in the following format :

$jsonArray = array(
    "facebook" => array("user" => "8", "user_id" => "10", "user_post" => "6"),
    "twitter" => array("user" => "8", "user_id" => "10", "user_post" => "6")
);

I've then done the following so I can access the array

echo "<script type='text/javascript'>window.MyArray = ".json_encode($jsonArray).";</script>";

And to access the array I tried the following

alert(window.MyArray['facebook'][0]['user']);

yet that's seemed to fail, any directions?

    window.MyArray['facebook'][0]['user']
    --------------------------^^^
    

    Why do you need [0] here?

    Use this:

    window.MyArray['facebook']['user']
    

    MyArray gives this:

    {
        "facebook": {
            "user": "8",
            "user_id": "10",
            "user_post": "6"
        },
        "twitter": {
            ...
        }
    }
    

    MyArray['facebook'] results in the following array:

    {
        "user": "8",
        "user_id": "10",
        "user_post": "6"
    }
    

    Therefore, MyArray['facebook']['user'] results in 8.
