How can I transfer an array of objects obtained from an ajax call to an observable array?

One of my functions involves making an ajax call and receiving data in the callback. It looks something like this:

function fetchData(callback) {
   //perform ajax
   if(callback) {
      callback(data.data);
   }
}

If I use the function like this:

fetchData(function(data) {
   return data;
})

I am able to retrieve the necessary data. How can I transfer all the objects along with their key/value pairs to a

self.list = ko.observableArray([]);
so that I have access to the data throughout the code?

Answer №1

My approach involves utilizing the Knockout Mapping Plugin along with the fromJSON command (sometimes fromJS is needed based on the data format) to seamlessly map incoming data from the source.

function fetchData() {
    $.ajax({
        url: 'http://...',
        dataType: 'json',
        success: function (data) {
            ko.mapping.fromJSON(data, {}, self.dataArray);
        }
    });
}
