Parse multilevel JSON String in Javascript

Question

I want to parse the following JSON string in Javascript:

str = {
    "weather":[{
        "id":803,
        "main":"Clouds",
        "description":"broken clouds",
        "icon":"04d"
    }],
    "cod":200
}

I normally parse JSON strings like this:

var obj = JSON.parse(str);
alert(obj.weather.description);

But in this case it doesn't work for me. How do I have parse such JSON strings?

If you have problems understanding the structure after parsing, assign it to a global variable and then play with it in console. — Mike B, Apr 14 '16 at 07:58

You just need to use

alert(str.weather[0].description);

As str is already an object, you don't need to parse() it again, this will result in an error.
Since weather is an array, You need to use index to access array's element.

You need to create an array like this:

alert(str.weather[0].description);
