PHP 执行查询任务前 先给用户返回“正在查询中..."
各位大牛 怎么能在用户提交查询后 先给用户返回”正在查询，稍候查看结果“
然后查询任务在服务器运行，因为查询时间长，不能等他出了结果再给返回。
------解决思路----------------------
ajax，点击查询时，显示正在查询...再请求后台查询，等待后台返回结果， 再显示查询出的数据
------解决思路----------------------
ajax查询，
用户点查询后，在前台用js显示等待。
然后后台处理完再更新前台数据显示。
------解决思路----------------------
ajax就行
