How to Read Json String

"How can I read given JSON String in JavaScript".

The verb "read" is a bit ambiguous, but if you wanted to evaluate it, you can use

JSON.parse()

You need to encapsulate the JSON in a quote that isn't used within your JSON to actually parse it, but looking at your code, there is no easy way to do it.. My advice to you is -

That JSON at some point is returned from some service as a string. Do a global replace on all single quotes, to replace them with a \" because as it stands, there is no way to evaluate it with single or double quotes.

A little tip on JSON too - be sure to run JSON through a json lint to make sure that it is valid.. trouble can stem from not having properly formatted JSON.

Use http://jsonlint.com for validating it.

Try :

var myObject = JSON.parse(your_JSON_variable);

Read:

var obj=JSON.parse(jsonstring);

obj.getTemperatureResult// contains the city array

back to string

JSON.stringify(obj);

You can't always count on the browser having JSON functions available out-of-the-box.

I'd suggest either using jQuery's $.parseJSON function or tapping into the excellent json2 solution.

Your JSON is odd. Inside the object you've nested another JSON string - instead of the array directly which it presents.

// Assuming your got the string from a XHR response directly:
var obj = JSON.parse(response);
// or you've got the object directly embedded in your script:
var obj = {"getTemperatureResult":"[[…]]"};

// then do:
var arr = JSON.parse(obj.getTemperatureResult);
