我在搜狐上查询了三只股票的数据，网址如下：
http://q.stock.sohu.com/cn/msq.shtml?q=cn_000022,cn_600019,cn_600028
打开网页之后，能看到一个表格，它的数据复制下来就是如下内容：
=======内容开始===========================================================
股票代码股票名称当前价涨跌额涨跌幅总手现手成交金额换手率今低-今高今开盘昨收盘
000022 深赤湾Ａ 11.70 -0.30 -2.50% 8844 86 1034 0.19% 11.60-11.80 11.60 12.00
600019 宝钢股份 5.17 -0.06 -1.15% 321813 63 16563 0.18% 5.11-5.19 5.15 5.23
600028 中国石化 7.01 -0.06 -0.85% 244512 47 17029 0.03% 6.90-7.02 6.97 7.07
=======内容结束===========================================================
如果我察看该网页的源代码，发现这一块相应的代码是：
=======代码片段开始===========================================================

股票代码	股票名称	当前价	涨跌额	涨跌幅	总手	现手	成交金额	换手率	今低-今高	今开盘	昨收盘

=======代码片段结束===========================================================

我的问题是为什么看不到“宝钢股份”、“600019”、“中国石化”这样字样？我当初学习html的时候，不是说网页上显示的东西都能在源代码中找到么？搜狐它这个网页为什么从源代码中找不到？

另外，如果用另存为的办法将网页保存到本地，也会发现三行股票数据消失，只剩下表格头：
=======保存到本地文件后观察到的内容开始===========================================================
股票代码股票名称当前价涨跌额涨跌幅总手现手成交金额换手率今低-今高今开盘昨收盘
=======保存到本地文件后观察到的内容结束===========================================================

为什么会出现这样的现象呢？

回复讨论(解决方案)

估计这些数据通过AJAX异步获取的。

我其实对如何获取那三行股票数据有兴趣，不知道搜狐这个页面用来获取数据的代码是不是藏在这个页面中？有高手请进来指导一下哦。

源代码指显示后台response过来的
JS打印的，包括AJAX的，是木有、

看这个JS文件

谢谢KongHuLu兄，这个js文件暂时看不太懂。咱们有木有什么办法通过调用这个js文件从自己的local服务器上搞一个网页来得到相同的数据？

或者说，如何用vba把这3行数据抓到excel或者access当中来啊？

学一下AJAX就明白了。保存什么的，就是保存页面的源码，不包括页面逻辑执行后的结果。
学明白AJAX就知道如何利用了，很简单。

谢谢，我学学去。
为了加快学习进度，theforever兄能否给个简单的例子？比如用excel的vba代码获取哪怕一个开盘价，剩下的我再慢慢学。

It should be displayed using js or the like, and there is no static output, so it is not in the source code, it is dynamic!

[Quote=quote 8th floor’s reply:]
Thank you, I will learn from it go.
In order to speed up the learning process, can brother theforever give a simple example? For example, I can use Excel's VBA code to get even an opening price, and I will learn the rest slowly. Can you give me some advice on how to solve your problem?
Sorry, I haven’t researched it yet.

I downloaded a book called Head First Ajax online. I don’t have time to read it yet, so I’ll post it first. Thank you.
