The script does not work in Firefox, what is the reason?

Question

JavaScript

Guys, I myself am not very savvy in JS, and even more so in regular expressions, but can someone tell me why the script, which works properly in all browsers, refuses to work in Mozilla?

$('#chooseFile').bind('change', function () {
        var filename = $("#chooseFile").val();
           if (/^\s*$/.test(filename)) {
            $(".file-upload").removeClass('active');
            $("#noFile").text("No file chosen..."); 
         }
         else {
            $(".file-upload").addClass('active');
            $("#noFile").text(filename.replace("C:\\fakepath\\", "")); 
         }
        });

Answer 1

Do not do this C:\\fakepath will be only on Windows, Linux, macos, mobile will have its own value. You can get the file name from Maybe for this reason it does not work in Firefox, I don’t remember exactly if the value is the same there or not.
