Convert the result of a dom.Node.getAttribute
call to appropriate Scala type.
Convert the result of a dom.Node.getAttribute
call to appropriate Scala type.
Note: HTML Attributes are generally optional, and dom.Node.getAttribute
will return
null
if an attribute is not defined on a given DOM node. However, this decoder is
only intended for cases when the attribute is defined.
// @TODO Orly? What about boolean attrs? How do we distinguish that? What about props?
Convert desired attribute value to appropriate DOM type.
Convert desired attribute value to appropriate DOM type. The resulting value should
be passed to dom.Node.setAttribute
call, EXCEPT when resulting value is a null
.
In that case you should call dom.Node.removeAttribute
instead.
We use null
instead of Option here to reduce overhead in JS land. This method
should not be called by end users anyway, it's the consuming library's job to
call this method under the hood.
