I am learning how to work with the google maps API, and would like to know how to pick up the current user location and enter the address in a form. There’s little you can do so far. Could you help me with that.

function init () {
				loadPosition();
			}

			function loadPosition(){
				if(navigator.geolocation){
					document.getElementById("status").innerHTML = "Seu navegador suporta HTML5!";

					navigator.geolocation.getCurrentPosition(funcaoSucesso,funcaoErro);
				}
			}

			function funcaoSucesso(posicao){
				var latitude = posicao.coords.latitude;
				var longitude = posicao.coords.longitude;
				

				if(!latitude || !longitude){
					document.getElementById("status").innerHTML = "Não foi possível consultar sua localização!"
				}

 
			}

			function funcaoErro(error){
				switch(error){
					case 0:
						alert("Erro ao atualizar a sua posição. Erro:"+error.message);
					break;
					case 1:
						alert("O usuário não compartilhou sua localização.");
					break;
					case 2:
						alert("O browser não está habilitado para localização.");
					break;
					case 3:
						alert("Tempo de requisição esgotado. [TIMEOUT]");
					break;
				}
			}

  • I didn’t understand very well. You want to enter the address based on latitude and longitude?

  • Yes, street, city and state.

The consumption of the following URL below, returns exactly one json. So you can interpret it and fill out your interest form, whichever way you prefer. See:

http://maps.googleapis.com/maps/api/geocode/json?latlng=44.4647452,7.3553838&sensor=true

Take a look at Reverse Geocoding referring to the Google documentation.
