Ajax 弹窗插件就可以了啊
我知道弹出窗口如何实现，我需要的是，哪些学校的数据从哪里来，难道要我一个一个的添加吗？不可能撒！
@Leo.zhou:网上可以找到现成的数据吧，我有一个数据库里面就有，不过服务器现在联不上。你可以先自己找下。
或者下个有这功能的程序源码，在数据库里取出来就可以了。
你能帮我找一个、我就是在G上找了N久也没找到源码！
@Leo.zhou:
你网上去找 02_Install initial Data.sql
这个Sql里有你要的数据

jquery ui组件里有dailog控件，数据当然是从数据库里读出来的。
我知道、我想有没已经做好了的！比如WS这些！

数据当然是一个一个添加了 怎么可能有不劳而获的事情 弄个excel导到数据库里
有没做好的比如WEBSERVICE这些。！
