How to Enable Cross-Origin Requests for Local Files in Google Chrome?

XMLHttpRequest Cross-Origin Requests for Local Files

Background:

When attempting to make AJAX requests using the $.get() method to files hosted on a local web server, you may encounter the following error in the Google Chrome console:

XMLHttpRequest cannot load file:///.... Cross origin requests are only supported for HTTP.

This error arises despite the absence of cross-domain issues, as the request is made from the same server that hosts the website.

Solution:

To resolve this issue, you can bypass the browser's cross-origin protection by starting Google Chrome with the --allow-file-access-from-files switch. This switch allows Chrome to access files from the local filesystem.

Instructions:

• macOS:

  • Open Terminal and type:

    open -a 'Google Chrome' --args -allow-file-access-from-files

• Linux/Unix:

  • Open a terminal and run:

    google-chrome --allow-file-access-from-files

• Windows:

  • Right-click on the Google Chrome shortcut and select Properties.

  • In the "Target" field, add the switch to the end of the path, e.g.:

    C:\ ... \Application\chrome.exe --allow-file-access-from-files
