Parsing JSON in Javascript [duplicate]

Question

I have the following code:

var addressInfo = [];
for(var x in address_components_root){
    addressInfo.push(address_components_root[x].long_name+"|||"+address_components_root[x].types[0]);
}


for(var d in addressInfo) {
    addressI = addressInfo[d].split("|||");
    if (addressI[1]=="street_number") {
        window.alert("street");
    }
}

address_components_root is a JSON encoded response as found at http://maps.google.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&sensor=false

How would I parse this json correctly like for example using eval so I don;t need to manually assign all the data?

JSON = Javascript Object Notation

@Sandro: And what do you want to say with that?

I just wanted to point that out. It is close to javascript.

In modern browsers you can use JSON.parse([json string]);. In older browsers you need a JSON library: see this page - use the json2.js file.

Ok, I receive the error : Uncaught TypeError: Object function json_decode(str_json) - is this because the data I get from google is already an object? Sorry, bit of a JSON noob here

It works here with the link you provided. See jsfiddle.net/hE8xf for the right syntax. What's in json_decode?

My bad, was using googles api. Already returns a JSON object. What a fool. I was using the same function on a server side version of the script that fetched the data from the REST api and then the client side which fetched it from the JS api.
