Hi,
New to the world of Qlik Sense Intregration, a recent request being able to present some of our departmental dashboards on TV screens around the office - the technical side of which we have all resolved.
My problem i'm faced with is each time the html/js calls the iframe (only variation being the Region selection) it creates a new session each time, so being in 30 secs cycles this is a new session for this user every 30 secs.
Is there a better way to accommodate this scenario where only the selection is timed and therefore not creating a new session each cycle?
Example code:
TV DEPARTMENTAL KPI
//
/* Change body background-color to change fade out color. */
body.siteshow { margin:0; padding:0; background-color:#ffffff; }
#menu
{
font-family:Arial;
font-size:9pt;
display:none;
opacity:0.00;
-mozopacity:0.00;
filter:alpha(opacity=0);
position:absolute;
top:10px;
left:10px;
padding:5px;
background-color:#000000;
color:#FFFFFF;
border:3px dotted #999999;
}
#menu a { color:#ffffff; }
#menu a:hover { text-decoration:none; }
#title { font-size:11pt; font-weight:bold; letter-spacing:2; }
#slides { font-size:9pt; line-height:16pt; }
.button { width:60px; font-size:9pt; letter-spacing:1; }
var current_idx = 0;
var slides = new Array();
var menuwin;

var menu;

var loaded = true;
// Define your "slides". 3 values for each are:
