Your very own address book!

copy the code below and go to repl.it/languages/JavaScript

Code:

var contacts = new Array();

function printPerson(person)
{
  console.log("Name:"+" "+person.firstName+" "+person.lastName+"  "+"Phone number:"+" "+person.phoneNumber+"  "+"Email:"+" "+person.email);
}

function list()
{
    var contactsLength=contacts.length;
 
    console.log("If you would like to know more about any entry, do 'search(firstName)'(firstName eaten by quotes)");
 
    console.log("Names:");
 
    for (var i=0; i<contactsLength; i++)
    {
        console.log(contacts[i].firstName+" "+contacts[i].lastName);
    }
}

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

function add(firstName,lastName,phoneNumber,email)
{
    this.firstName=firstName;
    this.lastName=lastName;
    this.phoneNumber=phoneNumber;
    this.email=email;
    contacts.push(this);
}

//List contacts here. [Syntax: var (shortname for person)=new add("firstName","lastName","phoneNumber","email")]

//Call functions here. {[printPerson(variable name);],[list();],[search(lastName);]}

Step 1. find

Code:

//List contacts here.

Step 2. go to the line under that, then type

Code:

var {shortname for person}=new add("{firstName}","{lastName}","{phoneNumber}","{email}"

(Put own parameters in { } braces.
Step 3. repeat step 2 as much as you want.
Step 4. list/search/printPerson as much as you want! If you want to list all entries, type

Code:

list();

. If you want to search for someone, type

Code:

search({firstName});

. If you want to printPerson them, do

Code:

printPerson({shortname for person});

This is my first real JavaScript program since I started taking online classes Saturday. To make an entry, you type

Code:

var (shortname for person)=new add("firstName","lastName","phoneNumber","email"

Functions:

• printPerson: This function will print a parameter given with extra text, and the parameter is the thing in between the parentheses. In this case the parameter will be the (shortname for person) what you called your variable.
  
• list(): This function takes no parameters. It will print out all the entries in the address book.
• search: This function will search through all the entries and match the firstName property. If it matches, it w/ill print it out with extra text.
• add("firstName","lastName","phoneNumber","email"): This function will take the inputs, exactly as written (YOU NEED THE QUOTES), and feed them into a variable.

If there are any bugs, let me know!

 

Code is very confusing.
