How do I dynamically change the content in the editor with JavaScript?

Just use the FCKeditor JavaScript API:

function getEditorValue( instanceName )
{
    // Get the editor instance that we want to interact with.
    var oEditor = FCKeditorAPI.GetInstance( instanceName ) ;

    // Get the editor contents as XHTML.
    return oEditor.GetXHTML( true ) ; // "true" means you want it formatted.
}

function setEditorValue( instanceName, text )
{
    // Get the editor instance that we want to interact with.
    var oEditor = FCKeditorAPI.GetInstance( instanceName ) ;

    // Set the editor contents.
    oEditor.SetHTML( text ) ;
}

How do I call a javascript function on the page containing the editor from a plugin?

If you want to call a function contained in the page that instantiates the FCKeditor, you will need to add "parent." to the function name in the plugin.js.

Let's say that in fun.html I have a function named "SetSelected". If I were writing a plugin for use on the fun.html page, and I wanted it to call the !SetSelected() function from plugin.js, I would simply have to add parent to it.

E.g. parent.SetSelected(); Sometimes you may have nested the editor another level; just add another parent like: parent.parent.SetSelected();
