how to get width, height or tinymce editor

Question

i'm trying to get width and height of tinymce editor.

i'm trying to set width and height of textarea fit with rich text editor.

tried with jquery, but default it returns width=100px only :|

setup : function(ed) {
        // Add a custom button
        ed.addButton('bbcodemode', {
            title : 'View BBcode source',
            image : '{link}/tiny_mce/themes/advanced/img/bbcodemode.gif',
            onclick : function() {
                $.ajax({
                    type: "POST",
                    url: "{link}/htmltobbcode/",
                    data: "ctn="+encodeURIComponent(tinyMCE.activeEditor.getContent()),
                    success: function(msg){
                        $('#post_content').val(msg);
                        //tinyMCE.activeEditor.setContent(msg);


                    }
                });

                alert($('#post_content_ifr').width());
                $('#post_content').css("width",$('#post_content_ifr').width());
                $('#post_content').css("height",$('#post_content_ifr').height());

                // Add you own code to execute something on click
                tinyMCE.execCommand('mceToggleEditor',false,'post_content');


            }
        });
    }

Answer 1

If the height and width of your editor have been set in the tinymce configuration you are able to get those settings from there using

tinymce.get('post_content').getParam('height');

and

tinymce.get('post_content').getParam('width');

Answer 2

$(tinyMCE.activeEditor.getContainer()).height()
