I have a question about create Element , TextNode or anything else like that in DOM.
Why do we use Document object to create Element ?
For Example: TextNode el = document.createTextNode("name").And then add el to one node.
Why don't we design a class like TextNode ?
And then instantiate it directly like TextNode el = new TextNode().
Finally,use a node to add it,like node.appendChild(el).
I think that we use Document object to create Element is unnecessary and is not fit to our thinking.
Do you have any suggestions about that ?
If you have ,Please send e-mail to [email protected]
Thanks very much!
