Title is taken from here. I just wanted to write my small example of template binding for future reference.
HTML:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="/index.js"></script>
<script type="text/javascript" src="/knockout-3.2.0.js"></script>
</head>
<body onload="doTheApply()">
Here is example from knockout:
<span data-bind="template: { name: 'person-template', data: buyer}"></span>
<script type="text/html" id="person-template">
<h3 data-bind="text: name"></h3>
<p>Credits: <span data-bind="text: credits"></span></p>
</script>
</body>
</html>
JS:
myViewModel = {
buyer: {name: "Franklin1", credits: 450}
}
function doTheApply() {
ko.applyBindings(myViewModel);
}

Another example:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="/knockout-3.2.0.js"></script>
</head>
<body>
My template:
<script type="text/html" id="myTemplate">
<input data-bind="attr: {type: inputType}" placeholder="I am going to be changed">
</script>
<span data-bind="template: {name: 'myTemplate', data: {inputType: 'search'}}">
</body>
<script type="text/javascript">
ko.applyBindings();
</script>
</html>
Here notice line:
<span data-bind="template: {name: 'myTemplate', data: {inputType: 'search'}}">
As you can see, $data I bind directly in the template definition.

One example with radio buttons:
HTML:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="/knockout-3.2.0.js"></script>
<script type="text/javascript" src="/index.js"></script>
</head>
<body>
<span data-bind="template: { name: 'myRadioButtons', foreach: myRadioButton }"></span>
<script type="html/text" id="myRadioButtons">
Test: <input type="radio" data-bind="checked: myValue"><p/>
</script>
</body>
</html>
JS:
var myRadioButtonViewModel = {
myRadioButton: [
{myValue: 1},
{myValue: 2}
]
}
window.onload = function () {
ko.applyBindings(myRadioButtonViewModel);
}

Title taken from here. For my example I did it with input.
Html:
<!DOCTYPE html> <html> <head> <script type="text/javascript" src="/knockout-3.2.0.js"></script> <script type="text/javascript" src="/index.js"></script> </head> <body onload="ko.applyBindings(viewModel)"> <input type="checkbox" placeholder="I am a test" data-bind="click: inputClick"></input> </body> </html>
JS:
var viewModel = {
inputClick: function() {
alert("just clicked input");
return true;
}
}
Here note return true. Without that state will not change (i.e. if for input you write type="checkbox")

With observables we can automatically update our binding, and CSS binding is to apply CSS or not. Check this code:
HTML:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="/knockout-3.2.0.js"></script>
<script type="text/javascript" src="/index.js"></script>
<link rel="stylesheet" type="text/css" href="/index.css">
</head>
<body onload="ko.clearBinding; ko.applyBindings(someModel)">
<button onclick="someModel.makeMeBold(!someModel.makeMeBold()); someModel.someText('frsfd')">CSS test</button>
I am another test <strong data-bind="text: someText"></strong>
<p data-bind="css: {knockoutTest: makeMeBold()}">Now I want some css to be binded.</p>
</body>
</html>
JS:
someModel = {
someText: ko.observable("I am a test!"),
makeMeBold: ko.observable(true)
}
CSS:
p.knockoutTest {
font-weight: bold;
}
p.makeMeItalic {
font-style: italic;
}
Note how I called:
someModel.makeMeBold()
and set "makeMeBold":
someModel.makeMeBold(!someModel.makeMeBold())
We are just setting css visible true or false.

Just a short note to myself, what we need for options binding, so that it can work properly.
<select autowidth="true" data-bind=" options: $root.carTypes ,optionsValue: 'carValue' ,value: myTest "></select>
Where myTest is like:
function CarsView(initialValues) {
var self = this;
self.myTest = ko.observable(initialValues);
}
If we need model to pass, then model should look like:
carsModel =
[
{
carTypes: ko.observable('Ferrari'),
myTest: ko.observable('Ferrari')
}
];
