如何使用JavaScript读取和写入文件 [英] How to read and write into file using JavaScript

问题描述

任何人都可以提供示例代码来读写使用JavaScript的文件？为了完整性，OP不会状态他正在寻找这样做在浏览器（如果他是，如前所述，这是一般不可能）

然而JavaScript本身确实允许这样做;它可以完成与服务器端JavaScript。

请参阅有关Javascript File class的文档

编辑：这个链接是现在被Oracle移动的Sun文档。

为了跟上这个时代，FileSystem类的node.js文档： a href =http://nodejs.org/docs/latest/api/fs.html =noreferrer> http://nodejs.org/docs/latest/api/fs.html

编辑（2）：您现在可以使用HTML5读取客户端文件： http://www.html5rocks.com/en/tutorials/file/dndfiles/

Can anybody give the sample code to read and write the file using JavaScript?

解决方案

For completeness, the OP does not state he is looking to do this in a browser (if he is, as has been stated, it is generally not possible)

However javascript per se does allow this; it can be done with server side javascript.

See this documentation on the Javascript File class

Edit: That link was to the Sun docs that now have been moved by Oracle.

To keep up with the times here's the node.js documentation for the FileSystem class: http://nodejs.org/docs/latest/api/fs.html

Edit(2): You can read files client side now with HTML5: http://www.html5rocks.com/en/tutorials/file/dndfiles/
