与其尝试对DOM做很多事情，为什么不只生成所需的输出并将其放入DOM？喜欢

const employee =[{"firstName":"Zahir","lastName":"Alam","Age":25,"Company":"Switchme","Role":"Developer","Department":"Tech","Head":{"Id":3,"Name":"Sourasis Roy"}},{"firstName":"Amith","lastName":"Manniken","Age":25,"Company":"Switchme","Role":"Developer","Department":"Tech","Head":{"Id":3,"Name":"Sourasis Roy"}},{"firstName":"Sourasis","lastName":"Roy","Age":28,"Company":"Switchme","Role":"CTO"},{"firstName":"Aditya","lastName":"Mishra","Age":29,"Company":"Switchme","Department":"Tech","Role":"CEO"},{"firstName":"Priti","lastName":"Lata","Age":24,"Company":"Switchme","Role":"HR"},{"firstName":"Sumita","lastName":"Nath","Age":24,"Company":"Switchme","Role":"HLA Head","Department":"Crm"},{"firstName":"Tarini","lastName":"Khanna","Age":22,"Company":"Switchme","Role":"Content Writer"},{"firstName":"Abhisek","lastName":"Soni","Age":23,"Company":"Switchme","Role":"HLA","Department":"Crm","Head":{"Id":5,"Name":"Sumita Nath"}},{"firstName":"Ankit","lastName":"Pump","Age":23,"Company":"Switchme","Role":"HLA","Department":"Crm","Head":{"Id":5,"Name":"Sumita Nath"}},{"firstName":"Pogo","lastName":"Laal","Age":23,"Company":"Switchme","Role":"Designer"},{"firstName":"Sabina","lastName":"Sekh","Age":28,"Company":"Switchme","Role":"HLA Head","Department":"Crm"},{"firstName":"Sanjay","lastName":"Poudal","Age":24,"Company":"Switchme","Role":"HLA Head","Department":"Crm","Head":{"Id":10,"Name":"Sabina Sekh"}}];

const filtered = employee.filter(e => e.Age > 23 && e.Age < 27).map(e => `${e.firstName} ${e.lastName}`);

$("div.age").text(filtered.join(", "));

<h3>4. List out all employee whose age&gt;23 and age&lt;27 ( comma separated)</h3>
<div class="age"></div>

我已经过滤掉了所需的员工，将它们映射到所需的字符串，然后通过加入将它们放入div中。

此外，当前代码无法正常工作的原因是，您不必担心div.age的先前值是什么，而每次都只是覆盖它。

我想遍历年龄> 23和<27
