Adressbok, exempel

// This is our "global" address book array.
// All code/functions/etc can access this variable, from everywhere.
var allContacts = [];



// Get a reference to our "save" button and bind a "click" event listener to it.
// The "listener" is in fact a function, that will be called when the button is clicked.
var saveButton = document.getElementById("spara-knapp");
saveButton.addEventListener("click", function () {

    // Get all the input values that the user has typed in our input fields, and save them in temporary variables for now.
    var tempFirstName = document.getElementById("first-name-input").value;
    var tempLastName = document.getElementById("last-name-input").value;
    // ...do this for all input fields...


    // Create a new object, that will be our new "contact".
    // Store all of the input values in the object.
    var contact = {
        firstName: tempFirstName,
        lastName: tempLastName
    };


    // Finally, we add the new contact object to our global variable, the address book array.
    allContacts.push(contact);
