location.hostname

could default to "localhost" and override by passing in host ip address through a query parameter

Added the following code to each example file to set "localhost" if the file is opened locally.

    var host = window.location.hostname;
    // if the file is opened locally, set the host to "localhost"
    if (window.location.protocol.indexOf("file:") === 0) {
        host = "localhost";
    }
    var arduino = new IOBoard(host, 8887);
