有時候需要驗證tinyMCE編輯器中的內容是否符合規范（不為空），就需要獲取里面的內容。
1、如果當前頁面只有一個編輯器：
獲取內容：tinyMCE.activeEditor.getContent()
設置內容：tinyMCE.activeEditor.setContent(“需要設置的編輯器內容”)
2、如果當前頁面有多個編輯器（下面的“[0]”表示第一個編輯器，以此類推）：
獲取內容：tinyMCE.editors[0].getContent()
設置內容：tinyMCE.editors[0].setContent(“需要設置的編輯器內容”)
3、獲取不帶HTML標記的純文本內容：
var activeEditor = tinymce.activeEditor;
var editBody = activeEditor.getBody();
activeEditor.selection.select(editBody);
var text = activeEditor.selection.getContent( { ‘format’ : ‘text’ } );
