javascript - 如何通过自动完成在 Angular 谷歌地图上放置标记？

Question

我想通过自动完成搜索在谷歌 Angular map 上放置标记，我正在以纬度和经度的形式获取位置，但标记没有添加，请检查......

Controller 代码为

$timeout(function() {

          var input = document.getElementById('pac-input');
          var searchBox = new google.maps.places.SearchBox(input);

          google.maps.event.addListener(searchBox, 'places_changed', function() {
             var marker= [] ;
             var places = searchBox.getPlaces();

             if (places.length == 0) {
               return;
             }

            var loc_data = {            

              coords: {
                  latitude: places[0].geometry.location.lat(),
                  longitude: places[0].geometry.location.lng()
              }
            };
            marker.push(loc_data);
            $scope.markers=marker;              
          });

HTML代码是

    <ui-gmap-markers models="markers" idkey="markers.id" coords="'coords'" >

    </ui-gmap-markers>

<div class="col-md-4">

    <input id="pac-input" class="controls" type="text" placeholder="Search Box">
</div>

//此示例使用 Google 地点自动完成功能向 map 添加搜索框 //特征。人们可以输入地理搜索。搜索框将返回一个 //选择包含地点和预测搜索词混合的列表。

    // This example requires the Places library. Include the libraries=places
    // parameter when you first load the API. For example:
    // <script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places">

        // Bias the SearchBox results towards current map's viewport.
