I use the easiest way to implement the CKEditor.
<!DOCTYPE HTML>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>CKEditor test</title>
<script src="ckeditor/ckeditor.js" type="text/javascript"></script>
</head>
<body>
<form method="post" action="ckeditor.php">
<input name="title" type="text" value="test" />
<textarea id="editor" name="editor" rows="10" cols="30"></textarea>
<input type="submit" value="go" />
</form>
<script type="text/javascript">
CKEDITOR.replace('editor', {
width: 600
});
</script>
</body>
</html>
This is the result, I type "hihi" in content area.
But when we change to the source code mode, Chrome will add some weird code in content that other browser won't, I change two computer and all the same, my CKEditor version is 3.6.2, and Chrome is 15.0.874.
