在TypeScript中分配DOM对象

Question

I'm trying to assign the DOM object of a webpage to a TypeScript variable.

protected DOM_obj : HTMLElement;
DOM_obj = document.defaultView;

I however seem to get the following error:

Type 'Window' is not assignable to type 'HTMLElement'. Property 'accessKey' is missing in type 'Window'.

How would I go about assigning the DOM object of the current window to a TypeScript variable?

As you can see in the TypeScript DOM API here

document.defaultView is of type Window .

So your DOM_obj needs to be of type Window as well:

protected DOM_obj : Window;
DOM_obj = document.defaultView;
