json file manipulation with javascript

I am getting json as response from server like below;

{"data":"<div align=\"left\"><select id =\"test\"><option id=\"1\" value=\"one\"开发者_如何学Python><option id=\"2\" value=\"two\" selected></select></div>"};

I want to manipulate above json file using javascript to change option one to be selected instead of option two.

Any hints please.

Regards,

Raj

Your life would be easier if your JSON was actually data represented as JSON, instead of serialized DOM fragments embedded in a JSON value, e.g.,

[
    {"value": "one"}
    , {"value": "two", "selected": true}
]

Then when you turn that into an object, you could just do something like this (assume for the sake of the example that you named the result myArray):

myArray[0].selected = true; // Select the first element
myArray[1].selected = false; // Deselect the other element; in many cases, you'd probably need some sort of loop.
