Code copying: add code content in the editor, and directly copy code language content when browsing articles and pages, ly_copy

This plug-in is green and efficient dynamic loading. Add code language content in the editor, and you can directly copy code language content when browsing articles and pages. If there is no code language content in articles and pages, the copy function file will not be loaded.

The effect is shown here:

         function clipboard_info(e, t) {             e = $(e.trigger);             var a = '';             b = e.html();             if (b != t) {                 a = b;                 e.html(t);             }             if (a) {                 setTimeout(function() {                     e.html(a);                 }, 3000);             }         }
