Utilizing JSON Objects to Populate a Knockout Form

I am looking to populate a form using knockout data-binding from a JSON object. I currently have the values hardcoded in my knockout setup, but what I really want to achieve is dynamically populating the form based on a JSON object. Here is a link to my FIDDLE

 <p>Hero Name: <span data-bind="text : HeroName" /></p>
 <p>Agent Writing Number: <span data-bind="text : HeroCode" /></p>
 <p>Contact Phone:  <span data-bind="text : ContactPhone" /></p>


var HeroDetails = $.get("GetHeroDetailsForVillianView", {
                HeroRequestIdForvillianDetailsView: HeroRequestIdForVillianDetailsView
            }, function (returnDataForDetails) {
                var results = JSON.parse(returnDataForDetails);

   $('#json').text(JSON.stringify({HeroName:'PeterParker', ContactPhone: '123456', HeroCode: 3 }, null, 4));


 function ViewModel() {
var self = this;

 self.HeroName = ko.observable("Peter Parker");
        self.ContactPhone = ko.observable("123456858");
        self.HeroCode = ko.observable("2455654");

 }

ko.applyBindings(new ViewModel());

Answer №1

For a more comprehensive understanding, I recommend visiting this section in the Knockout (KO) documentation. Additionally, you may find the details on the mapping plugin to be of interest.

Below is an example of the approach I typically follow:

function ViewModel(data) {
  var self = this;

  self.HeroName = ko.observable(data.HeroName);
  self.ContactPhone = ko.observable(data.PhoneNumber);
  self.HeroCode = ko.observable(data.HeroCode);

}

var viewModel;
$.getJSON("/some/url", function(data) { 
    viewModel = new ViewModel(data);
})

ko.applyBindings(viewModel);

Answer №2

There are multiple ways to achieve this task, and one simple method involves utilizing jQuery.

https://jsfiddle.net/2bwegmsv/4/

To accomplish this, I assigned unique ids to the desired div elements and integrated the following JavaScript code:

var myData = {HeroName:'PeterParker', ContactPhone: '123456', HeroCode: 3 };

    $('#hname').append(myData.HeroName);
    $('#agent').append(myData.ContactPhone);
    $('#contact').append(myData.HeroCode);

This implementation may require adjustments to meet your exact specifications, but it should provide valuable guidance.

Interactively: Only connecting JSON data.

let spidermanData = {Alias:'Peter Parker', Phone: '123456', CodeName: 3}; 
knockout.bind(spidermanData);
