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:

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',function(){

  this.removeListener('mode',arguments.callee);
}

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.
