I am really new to using AngularJS and Javascript. I need to get the totalResults data from a JSON source that looks like this: 

{
 "queries": {
  "request": [
   {
    "totalResults": "51"
   }
  ]
 }
}

Once I get the data, I need it to show up in a list using AngularJS. I have tried really hard using .ajax and .getJSON, but I am unable to get either of them to work, given my complete lack of knowledge on using JavaScript. I really appreciate your help! My AngularJS looks like this:

function MyController($scope){
        $scope.url = "https://www.googleapis.com/customsearch/v1?key=[MYKEY]&cx=[MYSECRETKEY]&q=flowers&alt=json&fields=queries(request(totalResults))";
        $scope.newMessage = "";
        $scope.messages = ["Steve Jobs - 515,000,000 results"]; 

        $scope.add = function(){
            $scope.messages.push($scope.newMessage);
        };
        }
  }

In the HTML part, I have this:

<input type="text" ng-model="newMessage">
    <input type="submit" ng-click="add()" value="Click to find out!">

When the user clicks the button, I want the url to be called and the $scope.newMessage should be the value in totalResults. Thanks for your help!

You can use $http service: Documentation

So you can:

$scope.add = function(){
  $http.get($scope.url).then(function(response) {
            $scope.newMessage = response.data.queries.request.totalResults;
            $scope.messages.push($scope.newMessage);
  });
};

I thought that callback receives response object, not the data directly. So perhaps it should be srvResponse.data.queries.request.totalResults? Or am I wrong? –  ŁukaszBachman Jan 22 '13 at 20:44
    
Corrent. I'll edit answer. –  Valentyn Shybanov Jan 22 '13 at 21:26
    
hey, this still isn't working for some reason. I tried adding an alert before the $scope.newMessage = response.data.queries.request.totalResults; part, but it's not getting called :( –  Prajoth Jan 23 '13 at 15:52
    
This is the issue that Google Chrome is showing: TypeError: Cannot call method 'get' of undefined at Object.MyController.$scope.add (file://localhost/Users/Prajoth/Downloads/index%202.html:16:17) at https://ajax.googleapis.com/ajax/libs/angularjs/1.0.1/angular.js:6129:19 at https://ajax.googleapis.com/ajax/libs/angularjs/1.0.1/angular.js:12496:13 at Object.Scope.$eval (https://ajax.googleapis.com/ajax/libs/angularjs/1.0.1/angular.js:7770:28) –  Prajoth Jan 23 '13 at 16:39

Can you post Plunker/Fiddle that shows this error? –  Valentyn Shybanov Jan 23 '13 at 18:15

Read a little in $http service provided by AngularJS

here is the hint to the code that you would use

$scope.add = function(){
    $http.get(url).then(function(response){
        queries = response.queries;
        $scope.newMessage = queries.request.totalResults;
    })
}
