假如我这样写：shimg =replace(thumbsurl(i),"/baidu/","x!")
然后这样：countimg=countimg & ""&shimg&""
就没有效果。问题出在哪？
如果直接这样就没问题：
countimg=countimg & ""&replace(thumbsurl(i),"/baidu/","x!")&""
但是，我有3个replace要执行啊，上面这样写，怎么一次写3个呢？
------解决方案--------------------
shimg = shimg & replace(replace(replace(thumbsurl(i),"/baidu/","x!"),"/yahh/","k!"),"/goo/","l!")
