ng-options:如何访问 object 中没有键或值索引的位置(索引)

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

我有一个 JSON 对象。如下:

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

我想要 drop-down 在这个对象中包含标题(使用 ng-options)。然后,我想使用 object 中所选标题的索引。 (假设 object 将用作数组(称为 myArray),正如 user194715 回答的那样 here
例如:

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

在这种情况下如何访问索引?

这样试试

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">
   </select>
 <span>{{myArray[select].Type}}</span>
 <span>{{myArray[select].Desc}}</span>
</div>
