HTML5 XML request on standalone player

Hi,

I want to use a HTML5 page that refers to a xml file via XMLHttpRequest on a standalone player without any network connection.

On my local pcs it works on firefox and edge, opera logs a cross origin violation.

The BrightSign seems to encouter an error as well, because the xml based content doesn't appear.

Is there any setting to allow local HttpRequest on the BrightSign?

    What web server is the code querying?

    HTML Local Files are referenced as file:// but HTTP requests would be http:// or https:// so there's a origin difference there.

    Is Enable external data ticked on the HTML5 state?

    See https://docs.brightsign.biz/display/DOC/HTML5
    and

    I don't use any webserver, it is completly local. I have 4 files index.html, main.js, styles.css and app.xml.

    I try to load the XML with:

    var xmlRequest    = new XMLHttpRequest();
    xmlRequest.onreadystatechange = xmlLoaded;
    xmlRequest.open("GET", "app.xml", true);
    xmlRequest.setRequestHeader( "Content-Type", "text/xml; charset=utf-8");
    xmlRequest.send();

    function xmlLoaded()
    {
        //manipulate divs based on xml content
    }

    External data is enabled.

    I'm not sure if there is another way to read xml, but I'm afraid this one doesn't work as standalone.

    Hi Lukas,

     

    Please see below for an example which is very close to what you want to do but with a JSON file...


    var url = "file:////published_file_playlist.json";

    function fetchLocalJSON(url) {
    var xmlhttp = new XMLHttpRequest();

    xmlhttp.onreadystatechange = function() {

    if (this.readyState == 4) {
    var myArr = JSON.parse(this.responseText);
    //StartPlayback(myArr);
    }
    };
    xmlhttp.open("GET", url, true);
    xmlhttp.send();
    }


    fetchLocalJSON(url);

    I don't see the difference to my approach, except it is for a JSON file and uses absolute and not relatvie path.

    I uses the exact same request method and doubt (and hope) that it won't make any difference that the path is absolute and the file type is XML.

    Have you tried it with an absolute path?

    How could that work? BrightAuthor renames alle files and put them into the pool folders on publish.
