Dynamically textarea with TinyMce editor

Add this function to you JavaScript:

function textarea_to_tinymce(id){
    if ( typeof( tinyMCE ) == "object" && typeof( tinyMCE.execCommand ) == "function" ) {
        tinyMCE.execCommand('mceAddControl', false, id);
    }
}

then when you create the textarea dynamically call it and pass the textarea’s id to it.

Just make sure TinyMCE is loaded on that page before or it won’t work.
