make readonly/disable tinymce textarea

Question

I need to disable or make readonly a tinymce textarea at runtime.

Answer 1

Use the configuration parameter readonly

tinyMCE.init({         ...         theme : "advanced",         readonly : 1 }); 

Here is a link to a demo.

Update: What you can do to prevent users from editing content in your editor is to set the contenteditable attribute of the editors iframe body to false:

tinymce.activeEditor.getBody().setAttribute('contenteditable', false); 

Answer 2

From version 4.3.x on you can use code below for readonly mode

tinymce.activeEditor.setMode('readonly'); 

and for design mode:

tinymce.activeEditor.setMode('design');
