I have seen other anti-Copy methods:
1. The window opened is a window without menus. In this case, right-click the window and you cannot view the source code directly on the current window page.
2. When Html data is displayed, a large number of white words are added. In this way, a large amount of junk information is added in the middle of the copy operation. For example, the following code:
<Font color = '# ffff'> aaaaaa </font> your <font color =' # ffff'> aaaaaa </font> content. These are your contents, but there will be problems with Copy.

Disadvantages:
It is troublesome for you, and it is not conducive to search engine indexing.
