Hello Knockout.JS
To start using Knockout.JS is very simple. It is nothing more than a couple of JavaScript lines of code and a special attribute added to the DOM tags.
An example of an HTML page can be as follows:
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title>Hello Knockout.JS</title>
</head>
<body>
<span data-bind="text: message"></span>
<script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/knockout/3.1.0/knockout-min.js"></script>
<script type="text/JavaScript">
var viewModel = {
message: "Hello Knockout.JS!"
};
ko.applyBindings(viewModel);
</script>
</body>
</html>Note
We put the script tags just before the closing body tag for performance reasons, as stated in the best practices document of the Yahoo Developer Network...
