Answer 1

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)

(为了完整起见，OP并未声明他正在浏览器中进行此操作（如前所述，如果不可能，通常是不可能的）)

However javascript per se does allow this;

(但是javascript本身允许这样做；)

it can be done with server side javascript.

(可以使用服务器端javascript来完成。)

See this documentation on the Javascript File class

( 请参阅 Javascript File类上的此 文档 )

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

(为了与时俱进，这里是FileSystem类的node.js文档： 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/
