使用angularjs进行地理编码服务

自动完成侦听器’place_change’发生在angular的$digest循环之外,因此您应该使用$evalAsync调用fillInAddress,否则在下一个摘要之前您将看不到表单更改.

纬度,经度存储在geometry.LOCATIOn中的位置对象上.

var app = angular.module('app',[]);

app.controller('myController',function($scopE) {
  var components = {
    street_number: 'short_name',route: 'long_name',locality: 'long_name',administrative_area_level_1: 'short_name',country: 'long_name',postal_code: 'short_name'
  };
  var autocomplete = new google.maps.places.Autocomplete(document.getElementById('autocomplete'),{
    types: ['geocode']
  });
  google.maps.event.addListener(autocomplete,function() {
    $scope.$evalAsync(fillInAddress);
  });
  
  $scope.formData = {};
  $scope.ll = {};

  function fillInAddress() {
    var place = autocomplete.getPlace();
    Object.keys(components).forEach(function(component) {
      $scope.formData[component] = '';
      document.getElementById(component).disabled = false;
    });
    
    place.address_components.forEach(function(component) {
      var addresstype = component.types[0];
      if (components[addressType]) {
        $scope.formData[addressType] = component[components[addressType]];
      }
    });
    $scope.ll = {
      lat: place.geometry.LOCATIOn.G,lon: place.geometry.LOCATIOn.K
    };
  }
});
