面臨 getExperience 方法的問題。不知道為什么我會得到這個，有人可以幫助我嗎？錯誤：在員工模型中測試自定義方法測試員工模型的 getExperience 方法在執行 getExperience 方法后檢查員工模型中的體驗失敗預期 0 為 21。 it('Checking experience in Employee Model after getExperience method execution', function() { var current_date = new Date(); var current_year= current_date.getFullYear(); var calculated_exp= current_year-1999; employee.getExperience(employee.get('year_of_joining')); expect(employee.get('experience')).toBe(calculated_exp); });var Employee = Backbone.Model.extend({ //Write your code here getExperience: function(experience) { var year_of_joining=employee.get('year_of_joining'); var current_date = new Date(); var current_year= current_date.getFullYear(); var calculated_exp= (current_year)-(year_of_joining); return calculated_exp; }});var employee = new Employee({ employee_id:1111, name:'Sarah Roe', year_of_joining:1999, address:'ABC Street', experience:0 }); alert("Experience of "+employee.get("name")+" is "+employee.getExperience(employee.get('year_of_joining'))+" years");; <html> <head> </head> <body> <div id="app"></div<script src="lib/jquery/dist/jquery.js"></script><script src="lib/underscore/underscore.js"></script><script src="lib/backbone/backbone.js"></script> <script type = "text/javascript" src="index.js"></script></html>

// JS with example of setting experience value being set third Example

// JavaScript

var Employee = Backbone.Model.extend({

//Write your code here

default: {

employee_id: 1111,

name: 'Sarah Roe',

year_of_joining: 1999,

address: 'ABC Street',

experience: null

getExperience: function(year_of_joining) {

var current_date = new Date();

var current_year = current_date.getFullYear();

var calculated_exp = (current_year) - (year_of_joining);

this.set({

experience: calculated_exp

});

return calculated_exp;

}

});

var employee = new Employee({

employee_id: 721,

name: "Shrikrishna",

year_of_joining: 1999,

experience: 22

});

//please add properties and values of Employee model

//employee.set({'experience': employee.get('year_of_joining')}) ;

alert("Experience of " + employee.get("name") + " is " + employee.getExperience(employee.get('year_of_joining')) + " years");

</script>

這是backbonejs中員工模型自定義方法的正確答案：

var Employee = Backbone.Model.extend({

//Write your code here

getExperience: function(year_of_joining) {

var current_date = new Date();

var current_year = current_date.getFullYear();

var calculated_exp = (current_year) - (year_of_joining);

this.set({

experience: calculated_exp

});

return calculated_exp;

}

});

var employee = new Employee({

employee_id:1111,

name:'Sarah Roe',

year_of_joining:1999,

address:'ABC Street',

experience:0,

});

alert("Experience of "+employee.get("name")+" is "+employee.getExperience(employee.get('year_of_joining'))+" years");

experience您從未為模型的屬性設置新值。為了讓您的測試通過，您應該使用： expect(employee.getExperience()).toBe(calculated_exp);

請注意， getExperience 函數永遠不會使用 experience 參數。

或者替換：

employee.getExperience(employee.get('year_of_joining'));

和：

employee.set('experience', employee.getExperience());
