Question

I did my first knockout.js application http://jsfiddle.net/Pqs7e/

For display application parts (books section, about section) I use jquery $(“#id”).show(). I feel this is not right way. How can I do this through the mechanism of the viewmodel?

Answer 1

I would do it with special state observable which would identify which div to show:

function ViewModel(){
    var self = this;
    self.state = ko.observable();
    ...
}

Then you just bind it like this:

<div id="books" data-bind="visible: state() === 'books'>...</div>
<div id="about" data-bind="visible: state() === 'about'>...</div>

and switch between states like this:

this.get('#books', function() {
    self.state("books");
});

this.get('#about', function() {
    self.state("about");
});
