js的Ajax删除数据成功后当前页面的数据刷新不出来

?????
是不是用了ajax的无刷新然后删除数据后不刷新了也就是说删除后更新不了是嘛？

是利用Ajax传数据到另外一个页面删除了数据，然后在调用Ajax来重新获取数据库的数据innerHTML到一个div里面。但是这个时候数据还是原来的数据，刷新不过来。除非是重新打开这个页面数据才会刷新的过来。

ajax与gridview结合无刷新新增、修改、删除数据的asp.net例子http://topic.csdn.net/u/20081215/16/fc6be5f1-bbed-403e-9864-6dd132294d20.html

回来时叫JS location.reload()
刷新页面

最好是这样，
首先调用AJAX将数据在数据库中删除，返回执行成功的标识后，直接调用JS在前台把那行数据删除就OK了，B/S架构核心就是尽量减少前后台的交互

还有种方法就是在你获得数据库数据时，页面后增加一个参数：如var url="getData.aspx?rnd"+Math.Random() 好让系统页面知道是新的数据请求

调试易

js的Ajax删除数据成功后当前页面的数据刷新不出来
