You can facilitate JavaScript “window.onmessage” method to send events from tabs, popups and iframes.

Set up a listener on your site

You will need to add a listener for those messages on your site:

window.onmessage = function (e) { 
    var event = e.split('|'); 
    if (e[0]==='uDash'){ 
        try { 
            uDash[e[1]](e[2],e[3]);
        }catch(e){
            uDash.saveMeta('Error','onmessage communication failed');
        } 
    };
};

Track events from a window opened by your site

To track data points from a popup or a tab use:

window.opener.postMessage('uDash|saveMeta|key|value', '*'); 

to save a meta event; or

window.opener.postMessage('uDash|saveAttribute|key|value', '*'); 

to save an attribute.

Please note that this will only work if popup or tab was opened by your site.

Track events from a window opened by your site

To save events from within an iframe, replace “window.opener” with “window.parent”:

window.parent.postMessage('uDash|saveAttribute|key|value', '*');
