How to return values from a modal dialog ?

Hello,

I have a modal dialog that opens fine, it is a php page, but I don't know how to return the 2 variables back to the plugin command function.

The alert(media); shows null.

(function() {

  CKEDITOR.plugins.lexicon = {
  };

  var plugin = CKEDITOR.plugins.lexicon;

  var commandFunction = {
    exec : function(editor) {
      var media = window.showModalDialog(editor.config.lexiconSelectUrl, null, "dialogWidth:750px;dialogHeight:500px;center:yes;resizable:yes;help:no;");
alert(media);
      if (media != false && media != null) {
/*        if (media.mediaUrl.substr(media.mediaUrl.length-4) == ".wmv") {
          var x = '<div title="click to play video" onclick="showMediaClip(this,'' + media.mediaUrl + '',' + media.width + ',' + media.height + ')" style="cursor: pointer"><img alt="" src="' + media.mediaImage + '" /></div>';
          editor.insertHtml(x);
        } else {
          editor.insertHtml("<img src='" + media.mediaUrl + "' />");
        }*/
      } 
    }
  }

  CKEDITOR.plugins.add('lexicon', {
    lang : [CKEDITOR.config.currentLanguage],
    requires : ['iframedialog'],
    init: function(editor) {
      var pluginName = 'lexicon';
      var commandName = 'insertLexiconEntry';
      var dialogName = 'lexiconLinkDialog';
      CKEDITOR.dialog.add(dialogName, this.path + 'dialogs/lexicon.js');
      editor.addCommand(commandName, commandFunction);
      editor.ui.addButton('Lexicon', {
        label : editor.lang.lexicon.toolbar_button,
        command : commandName,
        icon: CKEDITOR.plugins.getPath(pluginName) + 'images/lexicon.png'
      });
    }
  });

})();

I simply need the javascript code chunk that sits in the php modal window.

I tried this:

<script type='text/javascript'>
window.opener.CKEDITOR.tools.callFunction('$CKEditorFuncNum', '$tooltipDomId', '$tooltipClassName');
</script>

but it does not work.

Re: How to return values from a modal dialog ?

I solved my problem. At least, on Firefox. I could not test it on IE.

Here is the javascript code chunk that sits in the modal popup window.

<script type='text/javascript'>
  var getSelectedText = function(editor) {
    var selectedText = '';
    var selection = editor.getSelection();
    if (selection.getType() == window.opener.CKEDITOR.SELECTION_TEXT) {
      if (window.opener.CKEDITOR.env.ie) {
        selection.unlock(true);
        selectedText = selection.getNative().createRange().text;
      } else {
        selectedText = selection.getNative();
      }
    }
    return(selectedText);
  }

  var selectedText = getSelectedText(window.opener.CKEDITOR.instances.content);
  window.opener.CKEDITOR.instances.content.insertHtml('<span id="$tooltipDomId" class="$tooltipClassName">' + selectedText + '</span>');
</script>
