Fetch values in an iframe ArcGIS Online

VallottonNicolas

Hi, 

I'm pretty new with ArcGIS Javascript and i'd like to get the value of an ArcGIS Online map in an iframe.

When i click on the map, i saw that the request fetch is sent (on my own ArcGIS server) to get the values in a popup-container in the App : https://hepiageo2.hesge.ch/server/rest/services/p_anasol/ge_unite_exploitation/FeatureServer/0/query?f=json&objectIds=1387&outFields=betrieb_betriebsna%2Cbetriebsnu%2Cbezugsjahr%2Cidentifika%2Ckanton%2Cps_nr%2Cobjectid&outSR=2056&returnGeometry=false&spatialRel=esriSpatialRelIntersects&where=1%3D1

I'd like to put the data in an Array or create variable with the values. How can i get the fetch the request ?

Here is the map : https://arcg.is/10iKCv

Thanks!
