Retrieving JSON information from the server

I have been working with the knockout.js framework and adapted a basic contacts form example to suit my needs. I am able to successfully store values in my database, but I am encountering difficulties when trying to load values from the server. Despite having two contacts saved, the loaded values appear as empty fields. I have checked the ajax request in the console log and confirmed that values are being returned. How can I properly load the values from the server? DEMO

var ContactsModel = function (contacts) {
    var self = this;
    
    // Define observable array to hold contact data
    self.contacts = ko.observableArray(ko.utils.arrayMap(contacts, function (contact) {
        return {
            firstName: contact.firstName,
            lastName: contact.lastName,
            phone: contact.phone,
            alt_phone: contact.alt_phone,
            main1: ko.observable(contact.main1),
            main2: ko.observable(contact.main2)
        };
    }));

    // Functions to add and remove contacts
    self.addContact = function () {
        self.contacts.push({
            firstName: "",
            lastName: "",
            phone: "",
            alt_phone: "",
            main1: false,
            main2: false
        });
    };

    self.removeContact = function (contact) {
        self.contacts.remove(contact);
    };

    // Additional functions for managing phone numbers
    
    // Save function to convert data to JSON format
    self.save = function () {
        self.lastSavedJson(JSON.stringify(ko.toJS(self.contacts), null, 2));
    };

    self.lastSavedJson = ko.observable("");

};

// Fetching initial data from server using AJAX call
$.getJSON("functions/getPerson.php", function(allData) {
    var initialData = $.map(allData, function(person) { return new ContactsModel(person) });
    ko.applyBindings(new ContactsModel(initialData));
});

Answer №1

Delete this line:

let data = $.map(allEntries, function(item) { return new EntryModel(item) });

Give

ko.applyBindings(new EntryModel(allEntries));
(using allEntries) a shot.

Rather than:

ko.applyBindings(new EntryModel(data));
