Scan folder in javascript

I like the JavaScript equivalence of the PHP function:

echo json_encode(glob开发者_Go百科("images/*.jpg")) ?>);

is it possible ?

You can't scan a filesystem with javascript. If your site has empty directory indexing, you can parse the resulting html, and pull out a list of links to images.

In general, you are much better off just putting that php snippet in a file and calling it from javascript.

Javascript does not in any way/shape/form directly support file-based I/O, including reading directory contents.
