javascript - 在数组中存储和检索数据

Question

我需要你的帮助，

对于初学者来说，我在设置数组时遇到错误，如下所示。方法执行此操作然后检索其数据的正确方法是什么？如下所示？

var office_a = {    
    name: [{
        name: "Alpha Branch", mailstop: "AB"
    }],    
    divisions: [{
        division1: "Division 1 Office Name", mailstop: "DIV1",
        division2: "Division 2 Office Name", mailstop: "DIV2",
        division3: "Division 3 Office Name", mailstop: "DIV3"
    }]    
};

function test() {    
    alert(office_a[name].name); // -> "Alpha Branch"    
    alert(office_a[name].mailstop); // -> "B1"    
    alert(office_a[divisions][division1.name]); // -> "Division 1 Office Name"    
    alert(office_a[divisions][division1.mailstop]); // -> "DIV1"
}

test();

尝试这些(基本上您需要考虑关联数组内的数组索引)。检查这个fiddle

 var office_a = {    
    name: [{
        name: "Alpha Branch", mailstop: "AB"
    }],    
    divisions: [{
        division1: "Division 1 Office Name", mailstop: "DIV1",
        division2: "Division 2 Office Name", mailstop: "DIV2",
        division3: "Division 3 Office Name", mailstop: "DIV3"
    }]    
};
function test() {
console.log(office_a.name[0].name);
console.log(office_a.name[0].mailstop);
console.log(office_a.divisions[0].division1);
console.log(office_a.divisions[0].mailstop);
}
test();
