Hiding the nav-bar, while opening in the new window

I'm creating a web page where I'll display a table inside a div. I've a button called full view. When I click that button, only that div should be displayed in a new window. All others should be hidden. Only the div and the table inside it should be displayed. This is how I tried to display in the new window:

    <?php include("include-this/nav-bar.php"); ?>

<div class="panel panel-default" id="dash_div">
        <div class="panel-heading">
            Final
            <div id="contract_toolbar" name="contract_toolbar" class="btn-group pull-right">
                <button id="dashboard_full_view" name="dashboard_full_view" type="button" class="btn btn-info btn-sm" onclick="window.open('#dash_div', '_blank')">


Full View
                </button>
            </div>
        </div>
        <div class="panel-body">
            <table border="0" cellpadding="0" cellspacing="0" width="100%" id="table_dashboard" class="table table-striped table-bordered hide">
                <thead>
                    <tr>
                        <th></th>
                        <th>Total number</th>
                        <th>Total Value</th>
                    </tr>
                </thead>
                <tbody>
                </tbody>
            </table>
        </div>
    </div>  
    <script type="text/javascript" language="javascript">
    $(document).ready(function() {

            var input_report = jQuery("#input_report").val();
            //var table_id = "#table_report_" + input_report;
            alert(input_report);
            jQuery("#table_dashboard").removeClass("hide").addClass("show");
            jQuery("#table_dashboard").DataTable( {
                dom: "<'row'<'col-sm-12'Bftri>>" + "<'row'<'col-sm-4'l><'col-sm-8'p>>",
                paging: false,
                ajax: "db.php?report=" + input_report,
            });
        });

I've included the nav-bar in the first line. When I click the full view button, the div opens in a new window along with the nav-bar. But, I don't want that. I want to display only the div. I don't know what should I do to hide that nav-bar. Can someone tell me how to hide that when the div is opened in a new window?
