javascript - Call function initmap with parameters in gmaps api

Question

I have this function, the default function from google maps api tutorial, I have just added 2 parameters latt and lngg.

function initMap(latt,lngg) {


    var uluru = {lat: latt , lng: lngg};
    var map = new google.maps.Map(document.getElementById('map'), {
      zoom: 15,
      center: uluru
    });
    var marker = new google.maps.Marker({
      position: uluru,
      map: map
    });
  }

And I want to call it like they call it :

<script async defer
src="https://maps.googleapis.com/maps/api/js?key=AIzaSyAmjE35Pm1eDdyF6Vg3WC69opkqLIVt3GY&callback=initMap">
</script>

but using different parameters each time, because I will have 6000 maps, and I want to call the script for each function

I don't know if something like &callback=initMap(latt,lngg) is possible.

Thank you so much

Answer 1

You could have a separate script which sets the variables, and then have the initMap() call these variables.

var latt;
var lngg;

function setCoords(latt,lngg){
  this.latt = latt;
  this.lngg = lngg;
}

function initMap() {

    var uluru = {lat: latt , lng: lngg};
    var map = new google.maps.Map(document.getElementById('map'), {
      zoom: 15,
      center: uluru
    });
    var marker = new google.maps.Marker({
      position: uluru,
      map: map
    });
  }

<script type ='text/javascript'>setCoords(33.225488,-111.5955)</script>
<script async defer
src="https://maps.googleapis.com/maps/api/js?key=AIzaSyAmjE35Pm1eDdyF6Vg3WC69opkqLIVt3GY&callback=initMap">
</script>
