解决 moss content editor webpart 在 Rich Text Editor模式下 弹出脚步错误

Moss 自带的Content Editor Webpart 如果在Html Source中存在javascript事件，如以下Html：

<div id="contentarea">
    <div id="contentholder">
        <div style="margin-top: 58px;">
            <table width="806" border="0" cellpadding="0" cellspacing="0">
                <tr valign="middle" height="55">
                    <td class="roadmap_bg_55" id="btn23" onmousemove="rollOverBtn('btn23','maincss');">
                        Field force sizing
                    </td>
                </tr>
            </table>

            <script language="javascript" type="text/javascript">
            
                function rollOverBtn(id, className) {
                    alert('test');
                }
            </script>

        </div>
    </div>
</div>

则在切换到Rich Text Editor 模式下，鼠标移至Td中会弹出脚步错误：

 

解决办法是 改用 js 注册事件，Html 如下：

<div id="contentarea">
    <div id="contentholder">
        <div style="margin-top: 58px;">
            <table width="806" border="0" cellpadding="0" cellspacing="0">
                <tr valign="middle" height="55">
                    <td class="roadmap_bg_55" id="btn23">
                        Field force sizing
                    </td>
                </tr>
            </table>

            <script language="javascript" type="text/javascript">
 document.getElementById("btn23").onmouseover=function(){rollOverBtn('btn23', 'roadmap_bg_55');};
            
                function rollOverBtn(id, className) {
                    alert('test');
                }
            </script>

        </div>
    </div>
</div>
