How To Access Local Folders In Ajax Using File:///f:/foldername ? But It Works For Http://

Here I dynamically creating a file name list using AJAX jQuery using following code! $(window).load(function () { var fileExt = '.csv'; $(document).ready(function () {

Solution 1:

You can't.

Most browsers will block access (by XMLHttpRequest) to the local file system entirely, and those that don't do not provide a mechanism for reading directories.

For example:

Chrome says:

XMLHttpRequest cannot load file:///Users/me/tmp/. Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https, chrome-extension-resource.

Firefox says:

NS_ERROR_DOM_BAD_URI: Access to restricted URI denied

… although for a file rather than a directory, it will list the content (providing the file is in or under the same directory as the HTML document).

But f:///foldername can able to access in browser. But not able access in js ! Why?

Giving access to data on your hard disk to you, as the person controlling the browser, is different from giving access to that data to some JavaScript in a file that you might have downloaded from anywhere and which might do anything with it (such as sending it to the person who wrote the JS).
