jquery - 我想使用 jQuery 找到 Abhishek 的负责人

Question

我想比较关联数组中的值，并想打印我通过 Html 选择的人的头部

我的数组看起来像

var 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"}}];
$(document).ready(function(){
    $("select.employee").change(function(){
        var selectedEmployee = $(this).children("option:selected").val();
        $.each( employee, function( key, value ) {
            if(employee["firstName"]==selectedEmployee) {
                $("div.print").html("The head of"+selectedEmployee+"is"+employee["Head"]["Name"]);
            }
        });
    });
});
