Angularjs - How to use expression inside script tag

You can try doing something like, though I do think it may require further improvements since it has to execute after the scope has been created.

<script type="javascript">
                // Get to Angular scope
                var div = document.querySelector('[ng-controller=singleEventCtrl]');
                var theScope= angular.element(div ).scope();
                var event = theScope.<Whatever>;
</script>

<script type="application/ld+json">
                {
                  "@context": "http://schema.org",
                  "@type": "Event",
                  "name": '{{event[0].titulo}}',
                  "startDate" : "{{event[0].event_dataini_iso8601 | date:'yyyy-MM-dd'}}",
                  "endDate" : "{{event[0].event_dataini_iso8601 | date:'yyyy-MM-dd'}}",
                  "url" : "http://example.com/tourdates.html",
                  "location" :
                  {
                    "@type" : "Place",
                    "name" : "{{event[0].tb_town_townname}}"
                  }
                }
 </script>

Select allOpen in new window

ambience,

in the DOM, the {{event[0].something}} is note replaced with the value in the DOM.. doesn't work :\
Not outside the controller or inside..

As to gelonida answer i think it may work, but gonna need some time to implement and test..

Oh OK, sorry I forgot to update that part. I was thinking of changing it to

<script type="application/ld+json">
                {
                  "@context": "http://schema.org",
                  "@type": "Event",
                  "name": event[0].titulo,

This snippet now uses the object var event, which is fetched from angular scope in the other script block.

ambience, it may work if you get the values with javascript, but not for google.
google is not going to execute javascript to get the values, he is going to get the values inside the brackets 'some value' and not event[0].titulo.

I know google is able to get the page rendered after Angularjs finishes it, i tested it.
But i don't think is going to get this json with the values like that... because if you make inspect element in google chrome you can see the {{event.something}} transformed in real values. But not the: "name": event[0].titulo. inside the script tag.
It stays event[0].titulo

Thx! worked!
