We covered enabled and disabled binding in the last article. This article explains another very important type of binding i.e. knockoutJS checked binding. This time of binding binds the check-able HTML dom elements such as checkboxes and radiobuttons with the view model properties. It is important to note that the binding is two way. Checking a check box or radio button sets the value of the corresponding view-model parameter to true. Similarly, if you set the value of the parameter to false in the view model, it un-checks the corresponding HTML element. It is important to mention here that for HTML elements that are non-checkable, you should value-binding to set and retrieve values. Now, take a look at a very simple example of checked binding.
Take a very carefulllook at the following example to see knockoutJS checked bining in action.
