PHP - IE不显示数据库中的更新值。 Chrome，FF，Opera - 好的 [英] PHP - IE doesn't display updated values from database. Chrome, FF, Opera - OK

问题描述

我正在开发一个处理学生课程要求的系统，教师会根据这些要求提交答案。有一个包含新请求的列表框，当单击列表框中的选项时，request_id（listbox.this.value）通过AJAX查询数据库，查询结果显示在客户端 - 学生信息等。教师只需键入他的在指定的字段中回答，并且有一个更新查询，用一个答案更新数据库。但是稍后我点击列表框中的相同项目 - 显示所有数据（学生信息），但更新的信息（教师答案）除外。再次 - 它只发生在IE上。所有其他浏览器都没问题。

I'm working on a system that treats student course requests and teachers submit answers on those requests. There's a listbox that contains new requests, when clicked on an option item in the listbox, request_id (listbox.this.value) is querying the database via AJAX and query results are displayed back on client - student info etc. The teacher simply types his answer in an designated field and there's an update query that updates the database with an answer. But when later I click on the same item in the listbox - all the data displayed (student info) except of the updated info (teacher's answer). Again - it only occurs with IE. All rest of the browsers are fine.

提前致谢。

推荐答案

<我怀疑IE正在缓存对初始AJAX请求的响应。您可以尝试将时间戳附加到请求作为GET参数，这将强制IE发出新请求。

I suspect that IE is caching the response to the initial AJAX request. You can try appending a timestamp to the request as a GET parameter which will force IE to issue a new request.
