Question

我坚持使用此代码，这是对angularjs的一个课程作业。我是角度js的初学者，也是stackoverflow的新手。这是一个代码，可以找到一个人应该有多少。它计算项目数，然后显示结果。项目由＆＃39;，＆＃39;分隔。

＆＃13;

(function () {
  'use strict';
  angular.module('LunchCheck', [])
  .controller('LunchCheckController', LunchCheckController);

  LunchCheckController.$inject = ['$scope'];

  function LunchCheckController($scope) {
    //$scope.msg="";
    //console.log($scope.calculate);
    $scope.calculate="";
    $scope.check = Checker($scope);



  }

  function Checker(string) {
    var str = string.calculate;
    console.log(str);
    var str1 = str.split(',');
    var temp = str1.length;
    console.log(temp);

    string.msg=message(string,temp);
    }
    function message(string,temp) {
      if(temp > 3) {
        return "Too Much!";
   
    }
    else if (temp==0) {
      return "Aren`t you hungry??";
      
    }
    else {
      return "Enjoy";
      //console.log('Enjoy');
    }
    }


})();
