复制代码 代码如下:
<div>
<div> <a href="#">
<p>这个文档不错</p>
<div>
<div></div>
</div>
<span>70%(7000)</span> </a> </div>
<div> <a href="#">
<p>文档有待改进</p>
<div>
<div></div>
</div>
<span>30%(3000)</span> </a> </div>
</div>
主要一点就是通过百分比来控制g_img的宽度，至于css代码就不贴出来了。
演示代码:

有了demo，其他实现起来就方便多了，首先是页面获取html，页面第一次加载，用ajax获取后台数据，不要直接显示。(这里为了方便测试，就用asp作为后台语言)
下面是asp输出html代码
复制代码 代码如下:
function getdigshtml()'输出html
dim rsajax,sql,str,digsnum,undigsnum,digsnumall,digsper,undigsper
Set rsajax=server.CreateObject("adodb.recordset")
sql="select * from dig where id=1"
rsajax.open sql,conn,1,1
digsnum=rsajax("digs")
undigsnum=rsajax("undigs")
if isnull(digsnum) then digsnum=0
if isnull(undigsnum) then undigsnum=0
digsnumdigsnumall=digsnum+undigsnum
if digsnumall=0 then
digsper=0
undigsper=0
else
digsper=FormatNumber(cint(digsnum)/cint(digsnumall),3)*100
undigsper=FormatNumber(cint(undigsnum)/cint(digsnumall),3)*100
end if
str="<div>"
strstr=str&"<a href=https://www.jb51.net/JavaScript:isdigs('digs') >"
strstr=str&"<p>这个文档不错</p><div><div></div></div>"
strstr=str&"<span>"&digsper&"%("&digsnum&")</span>"
strstr=str&"</a></div><div>"
strstr=str&"<a href=https://www.jb51.net/JavaScript:isdigs('undigs') >"
strstr=str&"<p>文档有待改进</p><div><div></div></div>"
strstr=str&"<span>"&undigsper&"%("&undigsnum&")</span>"
strstr=str&"</a></div>"
getdigshtml=str
end function
输出完了 接下来就是前台获取，这时候我们就要用到jquery ajax，为什么不直接用ajax，原因很简单，我不会。。。。。看一下jquery中ajax代码，很简单
复制代码 代码如下:
function getdigshtml()//获取顶一下，踩一下html
{
$.ajax({
type:'POST',
url:'digg.asp',
data:'action=getdigshtml',
success:function(msg){
$("#digg").html(msg);
}
})
}
输出完了，接下来一步就是digs和undigs的操作了，跟获取html的代码差不多
复制代码 代码如下:
