get the rendering of an html js in a controller (symfony2) before any action has been done

Question

Could you please help me with this issue?

I have a js file that is connected to an API... it can get information about geolocalisation.

Anyway, I need to get this information in a symfony2 controller, but before any rendering (before the first rendering), any clues please?

PS : i could try file_get_contents , but this works with remote links, but not with a local file (where i put the html js). There is something I don't understant.

Thank you in advance for any help!

I guess you can follow this scenario :

• A first action of your controller calls a page where js is and colls the api
• This page then calls a second action of your controller (via window.location.href for example) and sends it the information, so the action can render what you want
