在 AngularJS 中使用 ng-checked（复选框）绑定数组中的所有值

Question

我需要使用复选框绑定人的姓名和年龄，由 ng-repeat 删除。我只能从数组中得到"name"，我不能从数组中得到"age"，你能找出我的错误吗？我已将所有代码附加到 Snippet 中。提前致谢。

另外附上图片请参考

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

myApp.controller('checkBoxController', function ($scope) {
  $scope.employees=[{name:'John', age:25, gender:'boy'},
       {name:'Jessie', age:30, gender:'girl'},
       {name:'Johanna', age:28, gender:'girl'},
       {name:'Joy', age:15, gender:'girl'},
       {name:'Mary', age:28, gender:'girl'},
       {name:'Peter', age:95, gender:'boy'},
       {name:'Sebastian', age:50, gender:'boy'},
       {name:'Erika', age:27, gender:'girl'},
       {name:'Patrick', age:40, gender:'boy'},
       {name:'Samantha', age:60, gender:'girl'}];
  $scope.selection=[];
  // toggle selection for a given employee by name
  $scope.toggleSelection = function toggleSelection(employeeName) {
     var idx = $scope.selection.indexOf(employeeName);

     // is currently selected
     if (idx > -1) {
       $scope.selection.splice(idx, 1);
     }

     // is newly selected
     else {
       $scope.selection.push(employeeName);
     }
   };
});

你可以试试这个：

在 'is newly selected' 中，您只推送了员工姓名。我将其更改为通过在员工数组中找到他来推送员工的整个对象。
在所选项目的 ng-repeat 中，我运行所有员工并打印其数据。

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

myApp.controller('checkBoxController', function ($scope) {
  $scope.employees=[{name:'John', age:25, gender:'boy'},
       {name:'Jessie', age:30, gender:'girl'},
       {name:'Johanna', age:28, gender:'girl'},
       {name:'Joy', age:15, gender:'girl'},
       {name:'Mary', age:28, gender:'girl'},
       {name:'Peter', age:95, gender:'boy'},
       {name:'Sebastian', age:50, gender:'boy'},
       {name:'Erika', age:27, gender:'girl'},
       {name:'Patrick', age:40, gender:'boy'},
       {name:'Samantha', age:60, gender:'girl'}];
  $scope.selection=[];
  // toggle selection for a given employee by name
  $scope.toggleSelection = function toggleSelection(employeeName) {
     const idx = $scope.selection.findIndex(employee => employee.name === employeeName);

     // is currently selected
     if (idx > -1) {
       $scope.selection.splice(idx, 1);
     }

     // is newly selected
     else {
      const employee = $scope.employees.find(employee => employee.name === employeeName);
       $scope.selection.push(employee);
     }
   };
});
