I'm new to javascript might be this question looks silly. How to check whether the html files are loading from local file system or server using javascript?

For example when I open the html files from my local system (/home/user/1.html) browser shows in url

file:///home/user/1.html

But if i load 1.html file into my local server then, if i access that file browser shows in url like below

http://localhost/GUI/1.html

I want to find whether files are loading from my server or local file system using java script.

Is there any way to find this using java script method.

You can use the window.location object to do that.

use window.location.protocol property.

The following line of code will return true if the file is being served from the file system.

window.location.protocol == "file:";

It basically checks if the protocol being used is file or not.

This only check for the Html file loaded in the browser.. all consecutive Javascript file requests generated from html page will not get checked.
because the question asked is about HTML files only.
