For the TINYMCE editor is unable to read and write content through JS, you must use the editor's own method, the following are some methods, I hope to use a friend to help:
1. If the current page has only one editor:
Get content: TinyMCE.activeEditor.getContent ()
Setting content: TinyMCE.activeEditor.setContent ("Editor content required")
2, if the current page has more than one editor ("[0]" below means the first editor, and so on):
Get content: Tinymce.editors[0].getcontent ()
Setting content: Tinymce.editors[0].setcontent ("Editor content required")
3. Get plain text content without HTML tags:
var activeeditor = Tinymce.activeeditor;
var editbody = Activeeditor.getbody ();
ActiveEditor.selection.select (Editbody);
var text = activeEditor.selection.getContent ({' Format ': ' Text '});
The text that is taken is the plain text content.
