To get data via Ajax in an HTML binding of Knockout.js, you can follow these steps:


Step 1: Create an observable array in your viewmodel where you will store the data received from the Ajax call. For example:

1
2
3
var viewModel = {
  items: ko.observableArray([])
};


Step 2: Use the jQuery Ajax function to make a request to the server and retrieve the data. You can do this in the init() function to load the data when the page is loaded. For example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
viewModel.init = function() {
  $.ajax({
    url: 'https://example.com/data',
    method: 'GET',
    success: function(data) {
      viewModel.items(data);
    }
  });
};

viewModel.init();


Step 3: Bind the data to your HTML using Knockout.js bindings. For example:

1
2
3
<ul data-bind="foreach: items">
  <li data-bind="text: $data"></li>
</ul>


This will loop through the items array in your viewmodel and display each item in a list.


Now, when the page loads, the Ajax call will be made to retrieve the data and the data will be displayed in your HTML using Knockout.js bindings.
