js里直接写html标签 用注释,无需转义

<script type="text/javascript"> 
document.write((function (){/* 
    <!-- 这里是注释 --> 
    <table border="1"> 
        <tr> 
            <td> 
                Hello Word! 
            </td> 
        </tr> 
    </table> 
    <script type="text/javascript"> 
        alert("Hello Word!"); 
    <\/script> 

*/}).toString().replace(/^.+?\*|\\(?=\/)|\*.+?$/gi, "")); 

</script>
