ng-options: How to access to position (index) in an object which has no index in key or value

I have a JSON obj. as below:

{"Title":"x", "Type":"y", "Desc":"First Description"},
{"Title":"r", "Type":"q", "Desc":"Second Description"}

I want to have a drop-down including Titles in this obj (using
). Then, I want to use the the Index of selected Title in the object. (Imagine the object will be used as array (called myArray), as what user194715 answered here)

for example:

var type = myArray[selectedIndex].Type;
var description= myArray[selectedIndex].Desc;

How can I access to the index in this case?

try like this

var app = angular.module("app",  []);

app.controller('mainCtrl', function($scope){
  $scope.myArray =
          {"Title":"x", "Type":"y", "Desc":"First Description"},
          {"Title":"r", "Type":"q", "Desc":"Second Description"}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<div ng-app="app" ng-controller="mainCtrl">
    <select ng-model="select" ng-options="key as value.Title for (key,value) in myArray">
