I'm learning to tinker with the google maps API, and would like to know how to grab the user's current location and enter the address into a form. To do little to date. You could 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;
				}
			}

Consuming the following URL, returns exactly json . So you can interpret it and fill in your interest form, any way you prefer. See:
