Need Javascript to Save locally before post

The only thing you can save locally with javascript is a cookie. Which could do what you want. Check out examples, there are millions.

You could use a timer to periodically save the editor contents to a cookie. Your code could look for this cookie on startup & offer it to the user: confirm("restore last session?").

If you are able to successfully save/load the editor contents from the FCKEditor iframe, then please post your code to do this or send it to jjbeahan@yahoo.com, because I am unable to successfully read/write the iframe's innerHtml (on Firefox, IE works fine), and I've spent over a week on this and am getting desperate. Thanks in advance for any help!

I just used the documented API calls:

setting editor contents:
var oEditor = FCKeditorAPI.GetInstance("FCKeditor1") ;
oEditor.SetHTML(html);

getting editor contents:
var oEditor = FCKeditorAPI.GetInstance("FCKeditor1") ;
var html = oEditor.GetXHTML(true);

It works fine for me on FF.
