AngularJS Google Maps Click 事件未在 ios 设备 ipad 和 iphone 中触发

Question

我已将 google maps API 与我的应用程序集成以提供自动完成建议，它在我的笔记本电脑 (Ubuntu) 所有浏览器上也能正常工作。但是，最近我用 iPad 和 iPhone 进行了测试，它不起作用。我无法点击建议的地点。我正在使用 AngularJS，我的代码 sn-p 如下：

HTML

<div class="row">
    <div class="col-md-6">
        <form name="searchForm" ng-submit="fillInAddress()">
            <div class="input-group well">
                <input type="text" class="form-control" id="autocomplete" name="city" placeholder="Enter your city" 
                onFocus="geolocate()" required />
                <span class="input-group-btn">
                    <button class="btn btn-primary" type="submit" ladda="ldloading.slide_left" data-style="slide-left" data-spinner-color="#000000"
                        ng-disabled="searchForm.$invalid">
                        <i class="fa fa-search"></i> Search
                    </button>
                </span>
            </div>
        </form>
    </div>
</div>

JS

 var placeSearch, autocomplete;

  function initAutocomplete() {
    autocomplete = new google.maps.places.Autocomplete((document.getElementById('autocomplete')),
    {types: ['geocode']});
    autocomplete.addListener('place_changed', fillInAddress);
  }

  function fillInAddress() {
    // Get the place details from the autocomplete object.
    var place = autocomplete.getPlace();
    locationfilter.lat=place.geometry.location.lat();
    locationfilter.lon=place.geometry.location.lng();
    $scope.getOrders($scope.reportParams,locationfilter);
  }

  $scope.getOrders = function(pagination, locationfilter) {
    $scope.working = true;
    sliveorders
      .getLocOrders(pagination, locationfilter)
      .then(function(res) {
        $scope.Orders=res.data;
        $scope.totalItems=res.total;  
        $scope.working = false;
      })
      .catch(function(err) {
        console.log('Location search err:', err);
        $scope.working = false;
      });  
  }

  function geolocate() {
    if (navigator.geolocation) {
      navigator.geolocation.getCurrentPosition(function(position) {
        var geolocation = {
          lat: position.coords.latitude,
          lng: position.coords.longitude
        };
        var circle = new google.maps.Circle({
          center: geolocation,
          radius: position.coords.accuracy
        });
        autocomplete.setBounds(circle.getBounds());
      });
    }
  };
  initAutocomplete();  

Answer 1

place_changed 事件在 IOS 上受到阻碍。解决方法是将placed_changed 事件包装在一个普通的click 事件中，然后像这样分派place_changed 事件：

document.getElementById('autocomplete')
  .addEventListener('click', e=>autocomplete.dispatchEvent('place_changed'));

所以initAutoComplete() 变成：

  function initAutocomplete() {
    autocomplete = new google.maps.places.Autocomplete((document.getElementById('autocomplete')),
    {types: ['geocode']});
    document.getElementById('autocomplete')
       .addEventListener('click', e=>autocomplete.dispatchEvent('place_changed'));
  }

这是一个使用 ng-map 的工作示例（在带有 IoS 9.2 的 iPad 上测试），这是一个用于 Google 地图的 AngularJS 库。

angular.module("app", ['ngMap']).controller("MyCtrl", function($scope, NgMap) {
    var vm = this;
    //vm.types = "['geocode']";
    vm.types = "['establishment']";
    vm.usebounds = false;
    
    vm.placeChanged = function() {
        vm.place = this.getPlace();
        console.log('location', vm.place.geometry.location);
        vm.map.setCenter(vm.place.geometry.location);
    }
    
    vm.geolocate = function() {
      if (navigator.geolocation) {
      	console.log("geolocate");
        navigator.geolocation.getCurrentPosition(function(position) {
          var geolocation = {
            lat: position.coords.latitude,
            lng: position.coords.longitude
          };
          console.log("position", position);
          if (vm.usebounds) {
            vm.mybounds = {
              center: geolocation,
              radius: position.coords.accuracy
            };
          }
          vm.map.setCenter(geolocation);  
        });
      }
    };
    
    NgMap.getMap().then(function(map) {
      	vm.map = map;
    });

});
