使用js定位到可编辑div的末尾 

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <title></title>
    </head>
    <body>
        <div contenteditable="true" id="guestbook_editor">2</div>
        <button onclick="set_focus()">aa</button>
        <script>
            function set_focus()
                {
                    var el=document.getElementById('guestbook_editor');
                    var range = document.createRange();
                    range.selectNodeContents(el);
                    range.collapse(false);
                    var sel = window.getSelection();
                    sel.removeAllRanges();
                    sel.addRange(range);
                }
        </script>
    </body>
</html>
