这是在看太平洋网的评论时看到的，太平洋网是用jsp做为后台语言，用来产生xml文件．然后在把数据绑定到html上的．我就用php也做了一个以下是源文件．
-----------------xml.htm------------------
<script><br> function jump(form)<br> {<br> if (form.pageNum.value>parseInt(pageCount.innerHTML)) return false;<br> if (form.pageSize.value>parseInt(recordCount.innerHTML)) return false;<br> ShopList.src="xml.php?pageNo="+form.pageNum.value+"&pageSize="+form.pageSize.value+"&time="+(new Date()).getTime();<br> }<br> function pageCount_onpropertychange(form)<br> {<br> if (form.pageNum.value>parseInt(pageCount.innerHTML)) form.pageNum.value=parseInt(pageCount.innerHTML);<br> if (form.pageSize.value>parseInt(recordCount.innerHTML)) form.pageSize.value=parseInt(recordCount.innerHTML);<br> if(form.pageNum.value==1)<br> {<br> form.firstPage.disabled=true;<br> form.previousPage.disabled=true;<br> }<br> else<br> {<br> form.firstPage.disabled=false;<br> form.previousPage.disabled=false;<br> }<br> if(form.pageNum.value==form.pageCount.value)<br> {<br> form.nextPage.disabled=true;<br> form.lastPage.disabled=true;<br> }<br> else<br> {<br> form.nextPage.disabled=false;<br> form.lastPage.disabled=false;<br> }<br> }<br></script>

以上的php，注释的是我连接数据库取得的数据，既然放上来测试，也没有数据库连接，所以改了一下．偶也是刚接解xml不久，很多地方还是不很懂．见笑了......
