无法将Json转换为jQuery

Question

This is my Ajax response from database :

{
    "docs": [{
        "_id":"5be81e62-f91d-4185-bef5-2eabdf048578",
        "_rev":"6-171639a97982fd7d04a81ed070b2e752",
        "profile_id":"5be81e62-f91d-4185-bef5-2eabdf048578",
        "name":"omar"
    }],
    "bookmark": "g2wAAAABaANkAB9kYmNvcmVAZGI1LmplbmV2ZXIuY2xvdWRhbnQubmV0bAAAAAJuBAAAAADAbgQA_____2poAkY_8AAAAAAAAGEBag"
}

I want to convert it to jQuery for Example :

var JsonData = jQuery.parseJSON(responseData.Value);
alert(JsonData.docs._id);

But the alert message show : undefined Need your help please and thanks.

Answer 1

docs is an array. An arrays store multiple docs in a single variable.

You need to tell the runtime which doc you want to attain the _id property of.

In your case there is only one doc so you can access the first using an index initializer:

alert(JsonData.docs[0]._id);

The [0] part pulls the first doc from the array.
