如何通过Angular 6指令将camelcase属性添加到dom元素？

Question

It seems impossible. Whether I use @HostBinding or elementRef.nativeElement.setAttibute(camelCaseAttribute, "true") in both cases the camelCaseAttribute becomes camelcaseattribute in the rendered dom.

All I want to do is set ngDraggable using a directive, why is that not possible? ( ngdraggable will not work)

Thanks a lot.

HTML attributes are not case sensitive. So it doesn't matter.

Attribute names for HTML elements may be written with any mix of lowercase and uppercase letters that are a case-insensitive match for the names of the attributes given in the HTML elements section of this document; that is, attribute names are case-insensitive.

If you are trying to add ngDraggable directive conditionally I think this is not a good approach. Imho you should ask another question how to apply ngDraggable dynamically.
