<script language="javascript">
function abc(){
alert('a');
}
</script>

<a href='bbbb'>abc</a>

<script language="javascript">
function abc()
{
document.write('<a href='a'>帮我去掉这段js</a>');
document.write('<a href=a[i]+c>')郁闷一天</a>;
}</script>

<a href="aaaa">agsdf</a>

最后结果就保留
<a href='bbbb'>abc</a>
<a href="aaaa">agsdf</a>

System.out.println(sb.toString());

System.out.println(res);
