JavaScript：帮助调试代码

问题描述

我正在编写一本简单的地址簿。这是我的代码：



var bob = {

firstName：Bob，

lastName： Jones，

phoneNumber：[phone]，

电子邮件：[email protected]

} ;



var mary = {

firstName：Mary，

lastName：Johnson，

phoneNumber：[phone]，

电子邮件：[email protected]

};



var contacts = [bob，mary];



function printPerson（person）{

console.log（person.firstName ++ person.lastName）;

}



函数列表（）{

var contactsLength = contacts.length;

for（var i = 0; i< contactsLength; i ++）{

printPerson（contacts [i] ）;

}

};



/ *创建搜索功能

然后称它为Jones* /

函数搜索（lastName）{

var contac tsLength = contacts.length;

for（var i = 0;我< contactsLength; i ++）{

if（contacts = person.Lastname）{

printPerson（contacts [i]）;

}

}

};

搜索（jones）;

＃---------- -----------------

我在想我的代码是搜索功能。对于搜索功能，我想通过拨打他的姓氏来联系我的联系人，并仅从我的联系人那里接收该人。为什么这段代码有问题？如果可以，请帮助调试此代码。谢谢你的时间！

I'm working on a simple Address book. Here is my code:

var bob = {
firstName: "Bob",
lastName: "Jones",
phoneNumber: "[phone]",
email: "[email protected]"
};

var mary = {
firstName: "Mary",
lastName: "Johnson",
phoneNumber: "[phone]",
email: "[email protected]"
};

var contacts = [bob, mary];

function printPerson(person) {
console.log(person.firstName + " " + person.lastName);
}

function list() {
var contactsLength = contacts.length;
for (var i = 0; i < contactsLength; i++) {
printPerson(contacts[i]);
}
};

/*Create a search function
then call it passing "Jones"*/
function search(lastName) {
var contactsLength = contacts.length;
for (var i = 0; i < contactsLength;i++) {
if(contacts = person.Lastname) {
printPerson(contacts[i]);
}
}
};
search("jones");
#---------------------------
I'm thinking the problem with my code is the search function. For the search function, I want to get a person in my contacts by calling his last name, and receiving only that person from my contacts. Why is there a problem with this code? If you could, please help be debug this code. Thank you for your time!
