    Check if local URL exists

    illustrate_this Level 1



      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);
          if (xhr.status == "404") {
              return false;
          } else {
              return true;
      var result = doesFileExist("page2.html");
      if (result == true) {
      } else


      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?
