Question

我正在为一个人格测验的后端工作，用户可以发送不同性格的客栈名称，一些问题以及问题的替代答案。用户（希望）也能够设置每个角色从答案的不同选择中收集多少分。涉及的数组内部有一些数组，数组中有对象。设置表单以便在可选答案的不同点发送时出现问题。我得到一个＆＃34;无法读取未定义的属性＆＃34;当我尝试将点记录到控制台时。下面是代码：

<html lang="en" ng-app="backend">
<head>
  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.5/angular.js"></script>
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
</head>
<body>
    <h1>points test</h1>      
    <div ng-controller="QuestionsController">
        <ul class="paa-linje">
          <form novalidate>
            <li class="paa-linje" ng-repeat="things in pointsArr track by $index">
             <input class="input"  type="number" min="0" max="10" ng-model="thing.points" required placeholder="0"/>
             </li>
            <input type="submit" ng-click="personPoints(thing)" value="Submit">
          </form>
        </ul>
  </div>
  <script>
      var app = angular.module('backend', [])

      app.controller('QuestionsController', function($scope) {
          $scope.pointsArr = [
          {nbr: 0, points: ''},
          {nbr: 1, points: ''},
          {nbr: 2, points: ''}
          ];

          $scope.personPoints = function(field) {
              console.log("points = " + field.points);
              for (var i = 0; i < $scope.pointsArr.length; i++) {
                  console.log("points = " + field.points);
              };
          };
      });
</script>
