Ckeditor update textarea

I am trying to get the ckeditor working. Obviously it doesn't make use of the textarea so on submit the form doesn't submit the text in the editor. Beceause I make use of polymorphic associations etc. I can't make a onsubmit function to get the value of the textarea (when the form is submitted) .

So I found this question: Using jQuery to grab the content from CKEditor's iframe

with some very good answers. The answers posted there keep the textarea up to date. That is very nice and just what I need! Unfortunately I can't get it to work. Does somebody know why (for example) this doesn't work?

I have a textarea (rails but it just translates to a normal textarea):
<%= f.text_area :body, :id => 'ckeditor', :rows => 3 %>

And the following js:

if(CKEDITOR.instances.ckeditor ) {
  CKEDITOR.remove(CKEDITOR.instances.ckeditor);
}
CKEDITOR.replace( 'ckeditor',
{
skin : 'kama',
toolbar :[['Styles', 'Format', '-', 'Bold', 'Italic', '-', 'NumberedList', 'BulletedList', 'Link']]});


CKEDITOR.instances["ckeditor"].on("instanceReady", function()
{
//set keyup event
this.document.on("keyup", CK_jQ);

//and paste event
this.document.on("paste", CK_jQ);
}

function CK_jQ()
{
 CKEDITOR.instances.ckeditor.updateElement(); 
}

I get the following "error" in my firebug.
missing ) after argument list [Break on this error] function CK_jQ()\n

Before submit do:

for(var instanceName in CKEDITOR.instances)
    CKEDITOR.instances[instanceName].updateElement();

have you figured it out?

I'm using CKEditor version 3.6.1 with jQuery form submit handler. On submit the textarea is empty, which to me is not correct. However there is an easy workaround which you can use, presuming all your CKEditor textareas have the css class ckeditor.

$('textarea.ckeditor').each(function () {
   var $textarea = $(this);
   $textarea.val(CKEDITOR.instances[$textarea.attr('name')].getData());
});

Execute the above before you do your submit handling ie. form validation.

Thanks @JohnDel for the info, and i use onchange to make it update every change.

CKEDITOR.on('instanceReady', function(){
   $.each( CKEDITOR.instances, function(instance) {
    CKEDITOR.instances[instance].on("change", function(e) {
        for ( instance in CKEDITOR.instances )
        CKEDITOR.instances[instance].updateElement();
    });
   });
});

Combination of all of the above answers into one.

Create a new custom.js file and add this:

CKEDITOR.on('instanceReady', function(){
  $.each( CKEDITOR.instances, function(instance) {

    CKEDITOR.instances[instance].on("instanceReady", function() {
      this.document.on("keyup", CK_jQ);
      this.document.on("paste", CK_jQ);
      this.document.on("keypress", CK_jQ);
      this.document.on("blur", CK_jQ);
      this.document.on("change", CK_jQ);
    });
  });

});

function CK_jQ() {
  for ( var instance in CKEDITOR.instances ) { CKEDITOR.instances[instance].updateElement(); }
}

You don't have to worry about the name of the textarea, just add a class ckeditor in the textarea, the above and you are done.
