Go to local URL with Javascript

When I try this:

window.location.href = "https://stackoverflow.com/questions/14052473/file:///C:/Users/Cerbrus/Documents/SomeFile.js"

(Yes, it is a valid path.)

Chrome throws me this error:

Not allowed to load local resource: file:///C:/Users//Documents/File.js

This is because JavaScript does not have access to local files (due to it being sandboxed), and you’re setting the new url with JavaScript.
“SandBoxed” means a technology has restricted (or no) access outside a certain set of bounds. In the case of browsers, this means that the code that runs on the page can not access files on your system (Otherwise, it would be easy to “steal” data, by just having a look at the user’s file system).

However,

Say, I have 2 files:

C:/Test/Test.htm
C:/Test/Test1.htm

Test.htm contains only this:

<script>
    window.location = "file:///C:/Test/Test1.htm";
</script>

This will actually redirect to Test1.htm, since the target file is on the same domain as where the source file’s from.
