Absolute file path for java script

Question

I have a small javascript library written by me. I want to reference it in my web application, but it does not work.

<script src='file:\\C:\Path\To\Script\Script.js'></script> 

Is it possible to reference javascript when everything you know is an absolute path?

Answer 1

URL file: requires 3 forward slashes, and paths also need forward slashes:

 <script src='file:///C:/Path/To/Script/Script.js'></script> 

This will only work if you download the script in an html file to your disk loaded into your browser.

Answer 2

Although I'm a Mac guy, my (limited) understanding of Windows security is that it has restrictions on running Javascript files “locally”. It would be best to copy the file to the web application directory structure and reference it through a relative path.

This will not only provide greater reliability, but also one more thing to keep in mind when deploying to a web server or something similar. If the JS file is outside the folder structure of the application, when deploying to a remote server, you still have to include it.
