这段js不是多次一举吗。散分

<script type="text/javascript">
<!--

不是
<script type="text/javascript">
<!--
if ((!document.images && navigator.userAgent.indexOf('Mozilla/2.') >= 0) || (navigator.userAgent.indexOf("WebTV") >= 0))
{
document.write('<a href="http://ad.doubleclick.net/jump/ecn.rbi/;type=cegbanner;pos=1;lay=webzine;sz=468x60;ptile=1;ord=1098071969?">');
document.write('<img src="http://ad.doubleclick.net/ad/ecn.rbi/;type=cegbanner;pos=1;lay=webzine;sz=468x60;ptile=1;ord=1098071969?" width="468" height="60" border="0" alt="ad"><\/a>');
}
//-->
</script>

是考虑Mozilla浏览器的

<img src="http://ad.doubleclick.net/ad/ecn.rbi/;type=cegbanner;pos=1;lay=webzine;sz=468x60;ptile=1;ord=1098071969?" width="468" height="60" border="0" alt="ad">
</a>
</noscript>

是浏览器不支持脚本时起作用
