Editor

A frame which is expected to contain an editable document. Set the value of the editortype attribute to 'html' to create an editor document. Mozilla provides two types of editors, the HTML editor and the plaintext editor. The editor does not provide any editing user interface; you would supply that yourself. However, text editing, image resizing, and table row and cell editing capabilities are provided. If you do not set the editortype attribute on an editor, you must enable editing using the makeEditable method.

To specify the document to load in the editor use the src attribute. However, an issue is that if you specify the src attribute initially on the editor tag in the XUL file, the document does not become editable by default. To enable editing on an editor, do one of two things:

  1. Set the src attribute on the editor after the outer window has loaded, for example, in the onload handler. You might also set the src attribute based on what the user selects from a file dialog. In this case, set the editortype attribute on the editor.
  2. Call the makeEditable function to make the document loaded in the editor editable.

To edit a new document, set the src attribute to 'about:blank'.

Example:

    <editor src="http://www.xulplanet.com"/>
    <button label="Edit" oncommand="this.previousSibling.makeEditable('html',false);"/>

The editor element implements the following interfaces:
