如何使用多维数组列表突出显示AngularJs 1.4.8中的搜索文本？

var myApp = angular.module('myApp', []);

myApp.controller('MyController', function ($scope) {
  // 初始化数据
  $scope.data = [
    {
      id: 1,
      name: 'John Doe',
      hobbies: ['reading', 'gaming', 'coding']
    },
    {
      id: 2,
      name: 'Jane Smith',
      hobbies: ['painting', 'dancing', 'music']
    },
    // 更多数据...
  ];

  // 初始化搜索文本
  $scope.searchText = '';

  // 定义一个函数，用于判断文本是否匹配搜索词
  $scope.isTextMatch = function (text) {
    return text.includes($scope.searchText);
  };
});

<div ng-app="myApp" ng-controller="MyController">
  <input type="text" ng-model="searchText" placeholder="Search">
  
  <ul>
    <li ng-repeat="item in data">
      <span ng-class="{ 'highlight': isTextMatch(item.name) }">{{ item.name }}</span>
      <ul>
        <li ng-repeat="hobby in item.hobbies" ng-class="{ 'highlight': isTextMatch(hobby) }">{{ hobby }}</li>
      </ul>
    </li>
  </ul>
</div>

.highlight {
  background-color: yellow;
  font-weight: bold;
}
