这个是浏览器的特性，你可以通过js来获取宽度
比如
//这个就是body的宽度，那么有滚动条和没有滚动条肯定是不一样的document.body.clientWidth //当然还有其他的属性就不列举了
唉，这样真不是爽，切换页面时，感觉导航左右晃。。。不太懂css，以为有解决办法呢

这样的话可以使用绝对定位来布局，这样就不会晃了~
CSS中设置始终出现滚动条即可。

楼上正解。让右侧一直有滚动条，高度不够的时候就没有bar，相比起因为滚动条的出现与否导致的左右晃动来说，可能更能接受一些吧。
body{overflow-y:scroll;} 另外一种相反的思路是，一直不出现滚动条。然后自己去判断下面的div是不是需要滚动条，如果div的高度>浏览器(页面可见）高度 - 导航栏的高度，就设置overflow：auto。
这样的问题在于，在打开页面和手动改变浏览器大小的时候，都需要去判断。这个倒是可以通过body的onResize方法来捕捉
<body onResize="resizeRightContent();">
但是还是太麻烦了，有点画蛇添足的感觉，还是让滚动条一直出现吧。。。
设置div的样式为：style="margin:auto; 就可以了
