Parsing JSON in AngularJS

Question

In my controller I am fetching the json by using $http.get like this:

$http.get('http://webapp-app4car.rhcloud.com/product/feed.json').success(function(data)

now data is a JSON and I want to get the value corresponding to JSON key. My key is stored in a variable "key". How can I access the value ? data.key is not working as key is a variable

You can use object as arrays in javascript, try:

data[key];

You mean you use the same syntax you'd use for an array. I strongly suspect data is not an array.

@DavidKnipe please learn about how bracket notation works in JavaScript before making incorrect remarks about it.

thanks, it is working and it is an object not an array @DavidKnipe

@Benjamin Please enlighten us.

@DavidKnipe In JavaScript you have two ways to access object properties. You can use the normal dot notation object.key and bracket notation object["key"] - in the second way (called bracket form) you access object keys by a dynamic string - so for example you can (but probably shouldn't) do something like: var x = {hello:"World"}; x["hell"+"o"] to get "World". In fact, even arrays are objects in JavaScript and even (in language specification, not practice) array keys are just string object keys that are coercible to UInt32 (arr["2"] and arr[2] are the same) es5.github.io/#x15.4

Use subscript notation.

data["key"];

Please create a fiddle for the same. Just a hunch, that your data is an array and hence you need to do something like data[0].key
