javascript - Angular $scope.list[index] 不更新

Question

我遇到的问题是，当我更新一个项目时， $scope.list 中的对象数组会更新，但是当我想要使用 $scope.list[index] 来获取特定项目时，它不会更新。以下日志给了我这个输出。

console.log("HEAD");
console.log($scope.list);
console.log(index);
console.log(index + ".id: " +$scope.list[index].id);
console.log(index + ".joke: " +$scope.list[index].joke);
console.log($scope.list);
console.log("END");

当我在浏览器中进行更改并希望将它们推回到后端时，就会发生这种情况。

控制台是:

此外，当我打开特定项目的日志时，它会发生变化。

  var getData = function () {

    // Angular $http() and then() both return promises themselves 
    return $http.get('http://192.168.12.11:8090/joke').then(function (result) {

      // What we return here is the data that will be accessible 
      // to us after the promise resolves

尝试如下。

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
        <script type="text/javascript">
        		var app=	angular.module("myApp",[]);

        		app.controller("myCTRL",function($scope){
        			
        			$scope.names =	[{name: 'arun'},{name: 'Mozhi'}];
        		});
        	</script>

        <body ng-app="myApp" ng-controller="myCTRL">
        	<div>          
        	</div><br>
        	<div ng-repeat="item in names">
        		<form novalidate>
        			<input type="text" placeholder="name" ng-model="item.name">
        			
        			<br><br>
        		</form>
        		
        	</div>
        	{{names}}
        </body>
