Does anyone know if I can use the "Onshow" of the lens to capture
variables?
I tried
<div class="map-lens" ex:role="lens" ex:onshow="dostuff"
style="display: none;">
and in the function:
function dostuff() {
var lat = window.database.getObject("ex:itemid","streetviewLat");
var lon = window.database.getObject("ex:itemid","streetviewLon");
alert("here");
}
which does not seem to do anything either...
