Re: Uncaught TypeError: Cannot read property 'nodeType' of null

Make sure you call ko.applyBindings in your document.ready handler:

$(function() {

    ko.applyBindings(vm);
});

PS - Props to Ryan Niemeyer since he just answered a similar question that reminded me about this email sitting in my inbox...  :)

Hi,

I'm trying the most basic sample in the tutorials and I'm getting an error:

"Uncaught TypeError: Cannot read property 'nodeType' of null " in the console window of Chrome from the knockoutjs library (2.2.1).

I've attached my code and the libraries I'm using. Any help will be much appreciated.

Thanks !!!

Hello,

The first question to ask is if you have used another view-model in the same view/page. When it happens, this usually occurs since vm's used one more time are stricted to be used by id joined with an element with id in the view/page.

The challange path is here (if the state is like yours):

1) Choose an element and give it an id like "js-vm-viewModelName1"
2)Choose an element and give it an id like "js-vm-viewModelName2"
3) Execute the applyBindings() for the viewModel objects like this: ko.applyBindings('custom-view-model-name', viewModel, 'js-vm-viewModelName1'); and ko.applyBindings('custom-view-model-name', viewModel, 'js-vm-viewModelName2');
4) Reload the page again,

Kind regards.
