Looking for help with a web form that allows users to upload files? I'm trying to find a way to access and extract the associated icon file from the user's system in order to include it along with the uploaded file. Any suggestions on how this can be achieved using JavaScript within the browser?
If you have any knowledge on this topic, your input is greatly appreciated. Thank you!
Accessing local files of a user using JS is restricted due to the security sandbox model implemented by all browsers. You can find more information about this security measure here and here.
However, for Mozilla-based browsers, there is a workaround available. By setting
netscape.security.PrivilegeManager.enablePrivilege(”UniversalFileRead”)about:config, users can access local files. For detailed instructions, refer to this link.
