Today is the first day for me in Knockout . Got struck with it . Below is my first sample code using knockout.js and it shows an error .

Cannot read property 'nodeType' of null

Here is my script:`

   function ViewModel()  

   {  

     var self = this;  

     self.n1 = ko.observable(10);  

     self.n2 = ko.observable(10);  

     self.n3 = ko.observable(10);  

   }  

   ko.applyBindings(new ViewModel());  `

Here is my html:

<body>

<p>Number1:<input data-bind=value:n1></input></p>

<p>Number2:<input data-bind=value:n2></input></p>

<p>Number3:<input data-bind=value:n3></input></p>

</body>

I want to know the reason for the above error and how to overcome it...

If you set up your code like this, it'll work.

<body>

<p>Number1:<input data-bind=value:n1></p>

<p>Number2:<input data-bind=value:n2></p>

<p>Number3:<input data-bind=value:n3></p>

<script src=knockout.js></script>

<script>



function ViewModel() {  

   var self = this;  

   self.n1 = ko.observable(10);  

   self.n2 = ko.observable(10);  

   self.n3 = ko.observable(10);

}  



ko.applyBindings(new ViewModel());  `



</script>

</body>
