问题
With angularjs, we usually use plain HTML to write views. Now I have a question: how can I show or hide some buttons depend on the user's rights?
For example, current page is displaying an article. If the current user is the author or the article, or administrator, then "Delete" button will be displayed.
But since the view is plain HTML, how can I control it?
I can post an request to pass some data(e.g. current user id, article id) to server to check, but if there are many buttons, I need to request many times, which is not effective.
Is there any better way to do this?

You can use the ngShow directive. I put together a little demo, but the important bit is simply:
<button ng-show="user.id==post.postedby">Delete</button>
