CanJS - Two way binding

Question

How to do two-way binding using CanJS?

Enter the Text : <input type="text" name="name" can-value="enteredText" />
Display the Text: {{enteredText}}

Can show multiple approaches? Using ViewModel ?

Answer 1

can-value was the old method in v2. In Canjs 4.0, you would do two way binding like this:

Enter the Text : <input type="text" name="name" value:bind="enteredText" />
Display the Text: {{enteredText}}

See: https://canjs.com/doc/can-stache-bindings.twoWay.html

Here's a jsbin demonstrating the syntax:

Answer 2

Please have a look here (docu for v2 and for v3).

At least if you use the (nowadays recommended) components approach you can write

<my-component {(some-prop)}="value"/><!-- v2 -->
<!-- syntax for v3 remains: {(prop)}="key" for two-way binding. -->

This is from the documentation.
