自写

if($('p').text()),判断P是否有文字．

 

<script type="text/javascript">
$(document).ready(function(){
$("a").each(function(i){
var cc=$(this).attr("href");
this.href = "http://www." + cc + ".com";
});
});
</script> //也能用

修改后

<script language="javascript">
$(document).ready(function(){$("a").not($("a[title]")) .each(function(i){ var cc=$(this).attr("href");this.href = "index.php?page=" + cc}); });
</script>"

修改后

<script language="javascript">
$(document).ready(function(){$("a").filter(".bbc") .each(function(i){ var cc=$(this).attr("href");this.href = "index.php?page=" + cc}); });
</script>
