使用ajax / javascript / jquery文件wachting系统 [英] File wachting system with ajax/javascript/jquery

问题描述

嘿伙计们，

我正在我的小应用程序中读出一个.txt文件。此文件现在更新，我希望每次更改此文件时都重新加载页面。这甚至可能吗？我考虑过编写一个函数来检查文件是否每次更新，但我怎么能知道它确实已更新？



有什么建议吗？

Hey guys,
i am reading out a .txt file in my little application. This file is updated then and now and i want the page to reload everytime this files was changed. Is this even possible? I considered writing a function which checks every second if the file was updated, but how can I figure out that it really was updated?

Any suggestions?

推荐答案

我不确定这可以做到，但是一点点的研究让我得到了一篇关于Node.js使用的文章（和代码库）功能。

看一看DirectoryWatcher fileChanged事件，我认为它正是您正在寻找的。我没有测试过这个，所以请告诉我这是怎么回事。

I wasn't sure that this could be done, but a little research led me to an article (and codebase) on the use of Node.js that would allow for exactly this functionality.

Monitoring a Folder for Changes in Files and Folders with Node.js[^]

Take a look at the DirectoryWatcher fileChanged event, I think it is exactly what you're looking for. I haven't tested this, so please let me know how this works out for you.
