这是我有：

var mainApp = angular.module("mainApp", []); 
     mainApp.controller('studentController', function($scope) { 
      $scope.student = { 
       firstName: "Muhammad", 
       lastName: "Waqas", 
       fees:500, 
       subjects:[ 
        {name:'Physics',marks:70}, 
        {name:'Chemistry',marks:80}, 
        {name:'Math',marks:65} 
       ], 
       fullName: function() { 
        var studentObject; 
        studentObject = $scope.student; 
        return studentObject.firstName + " " + studentObject.lastName; 
       } 
      }; 
     });

我不清楚了解这里的问题。但是你的目标是在$scope中创建一个students数组，你可以这样做。

mainApp.controller('studentController', function($scope) { 
    $scope.students = []; 
    $scope.students.push({ 
     firstName: "Muhammad", 
     lastName: "Waqas", 
     fees:500, 
     subjects:[ 
      {name:'Physics',marks:70}, 
      {name:'Chemistry',marks:80}, 
      {name:'Math',marks:65} 
     ], 
     fullName: function() { 
      var studentObject; 
      studentObject = $scope.student; 
      return studentObject.firstName + " " + studentObject.lastName; 
     } 
    }); 
    //add more students using .push() 
});

在那里你有你的学生数组在$范围内。

回答：

你不能这样做，关于$scope.student而是创建student因为只有一个对象，并创建一个数组$scope.students并存储在每个student对象array.SImilarly您可以创建var student1,var student2存储约其他学生

mainApp.controller('studentController', function ($scope) { 
     $scope.students = []; 
     $scope.studentFullName = function() { 
     }; 
     var student = { 
      firstName: "Muhammad", 
      lastName: "Waqas", 
      fees: 500, 
      subjects: [ 
       {name: 'Physics', marks: 70}, 
       {name: 'Chemistry', marks: 80}, 
       {name: 'Math', marks: 65} 
      ], 
      fullName: this.firstName + ' ' + this.lastName 
     }; 
     $scope.students.push(student); 
    });
