面临 getExperience 方法的问题。不知道为什么我会得到这个，有人可以帮助我吗？错误：在员工模型中测试自定义方法 测试员工模型的 getExperience 方法 在执行 getExperience 方法后检查员工模型中的体验失败 预期 0 为 21。<!-- Test Case--> 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");; <!-- Hmtl --><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>

这是backbonejs中员工模型自定义方法的正确答案：
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您从未为模型的属性设置新值。为了让您的测试通过，您应该使用： expect(employee.getExperience()).toBe(calculated_exp);
请注意， getExperience 函数永远不会使用 experience 参数。
或者替换：
employee.getExperience(employee.get('year_of_joining'));
和：
employee.set('experience', employee.getExperience());
