Sorry for my English. How to make preview with 3 editors, html, css and JS? I have problem with js because, code is insert to < head > iframe but not working.
code function `
function updatePreview() {
var previewFrame = document.getElementById('preview');
var preview = previewFrame.contentDocument ;
preview.open();
preview.write(AreaHTML.getValue());
preview.close();
$("#preview").contents().find("head").html('<script type="text/javascript">'+AreaJS.getValue()+'</script>');
$("#preview").contents().find("head").html('<style type="text/css">'+AreaCSS.getValue()+'</style>');
}
setTimeout(updatePreview, 300);
`
