Unveiling the Magic of Knockout.js: Extracting the Object Data

I recently started experimenting with knockout and have a query. Here is an excerpt of the code:

function Task(data) {
    var self = this;
    self.name = ko.observable(data.name);
}

function ViewModel() {
    self.taskArr = ko.observableArray([
    // some default data
    new Task({ name: "to-do 1"}),
    new Task({ name: "to-do 2"}),
    new Task({ name: "to-do 3"})
]);

Essentially, my goal is to log the contents of the object using console.log(). However, when I try console.log(self.taskArr()); I receive [Task, Task, Task] as output.

If I use self.taskArr()[0].name, I am only able to fetch the first result, not all of them.

Answer №1

If you want to show the information from an observable array, you will need to utilize the ko.toJSON method, like this:

console.log(ko.toJSON(self.taskArr()));

This code will display:

[{"name":"to-do 1"},{"name":"to-do 2"},{"name":"to-do 3"}]

Answer №2

One method to consider is converting the Task objects into JSON strings:

    Displaying as a JSON string: console.log(JSON.stringify(self.taskArr()));
