Accessing JSON object keys having spaces

Question

I have following json object      id    109      No  of interfaces    4      Following lines work fine   alert obj id   alert obj  id       But if keys have spaces then I cannot access their values e g   alert obj  No  of interfaces      Syntax error   How can I access values  whose key names have spaces  Is it even possible

The way to do this is via the bracket notation.

_x000D_

var test = {_x000D_
    "id": "109",_x000D_
    "No. of interfaces": "4"_x000D_
}_x000D_
alert(test["No. of interfaces"]);

_x000D_

The answer of Pardeep Jain can be useful for static data  but what if we have an array in JSON   For example  we have i values and get the value of id field  alert obj i  id     works    But what if we need key with spaces   In this case  the following construction can help  without point between    blocks    alert obj i   No  of interfaces       works too
