Javascript API

I couldn't find documentation on how to talk to the javascript API. I figured that through CKEDITOR.instances.id_of_textarea.setData(string); I could update the contents or get it with getData();

First thing I learned I can also access an instance of an editor through: CKEDITOR.instances["id_of_textarea"].setData(string); //This is more usefull in generic code.

I wanted to see which functions are available for me and show that in... the editor itself. I did the following.

var objEditor = CKEDITOR.instances["id_of_textarea"];
var str = "";
for (var item in objEditor) {
  str += "<strong>" + item + "</strong>=" + objEditor[item].toString().str_replace("\n", "<br>").str_replace(";", ";<br>  ").str_replace("{", "{<br>  ").str_replace("}", "}<br>").str_replace(";<br>  }", ";<br>}") + "<br>";
}
objEditor.setData(str);

With this output (I aligned the code a bit for readibility):

getThemeSpace = function(l) {
  var m = 'cke_' + l,
  n = this._[m] || (this._[m] = a.document.getById(m + '_' + this.name));
  return n;
}

focus = function() {
  var n = l(this);
  if (n) n.focus();
}

setMode = function(n) {
  var o, p = this.getThemeSpace('contents'),
  q = this.checkDirty();
  if (this.mode) {
    if (n == this.mode) return;
    var r = l(this);
    o = r.getData();
    r.unload(p);
    this.mode = '';
  }
  p.setHtml('');
  var s = l(this, n);
  if (!s) throw '[CKEDITOR.editor.setMode] Unknown mode "' + n + '".';
  if (!q) this.on('mode',

Anybody who wishes to talk to an instance of the CKeditor through the javascript API, now has a starting point and is able to see which functions are available for an instance of an CKeditor.

If you find yourself able to use any of these functions, please create your account here on the wiki and document it. The developers of CKeditor are working crazily on coding CKEditor v3.

getting the CKeditor focus using the API

To respond to the focus event of the editor:

var my_id='your_editor_id'; //this is the same as the id of the replaced text field
var the_ed=CKEDITOR.instances[my_id]
//respond to focus event
the_ed.on( 'focus', function()

  //show the editor data as example
  alert(this.getData());
});
