Check if local URL exists

Hi,

I would to perform a validation on whether a local file/URL exists.

I have searched into this trying various examples however none of them seem to work including the following:

function doesFileExist(urlToFile)
{    var xhr = new XMLHttpRequest();    xhr.open('HEAD', urlToFile, false);    xhr.send();       if (xhr.status == "404") {        return false;    } else {        return true;    }
}




var result = doesFileExist("page2.html");

if (result == true) {
    console.log("yes");
} else    console.log("no");
}  

In this example if my file does exists I get the correct output of "yes". However if this file does not exist I get the following error:

XMLHttpRequest cannot load file:///D:/edgeTest/page2.html. Cross origin requests are only supported for HTTP.

Can anyone give me any information to why this might be happening?

Thanks
