Question

我一直在尝试在我的谷歌地图上实施infowindow 使用geocomplete.js 进行搜索/获取街道详情以及获取lang / lat。现在我需要一个infowindow标记，以便当用户点击标记时，我可以显示更多信息，但我无法让它工作，因为我无法得到任何错误，以便我可以调试和解决它。我知道我错过了一些东西，但我认为我的代码很简单，我应该得到infowindow.Here是我的_view.html.erb中的代码，它是在bootstrap 3模式上呈现的。

<script src="http://maps.googleapis.com/maps/api/js?sensor=false&amp;libraries=places"></script>
  <script src="assets/jquery.geocomplete.js"></script>
<p class="text-center text-success">Add a location</p>
<hr>
 <div class="container">
 <%= form_for(@place,:html=>{:multipart => true,:remote=>true,:class=>"form-horizontal",:role=>"form"}) do |f |%>

      <%= f.text_field :address,:class=>"form-control" %>
      <p class="text-info" style="font-size:10px !important;">if you cannot find the location,Drag the marker on the map. </p>

          <div id="logs" data-lat="<%=  current_user.latitude%>" data-long="<%=  current_user.longitude%>">
              <%= current_user.address %> 
          </div>    


      <div id="mapnew" style="width:500px;height:500px"></div>

  <%end%>

  </div>   


<script type="text/javascript">


var lat=$('#logs').data("lat");
var long=$('#logs').data("long");


  var myLatlng = new google.maps.LatLng(lat,long);
var options = {
  map: "#mapnew",
  location: myLatlng,
  mapOptions: {
    streetViewControl: false,
    center: myLatlng,
    mapTypeId : google.maps.MapTypeId.ROADMAP
  },
  markerOptions: {
    draggable: true
  }
};


function initialize(){
$("#place_address").geocomplete(options).bind("geocode:result", function(event, result){
  $('#logs').html('<b>'+result.formatted_address+'</b>');
  var map = $("#place_address").geocomplete("map");
  map.setZoom(15);
  map.setCenter(result.geometry.location);
  //get the marker
  /////////////////////////////here i get the marker to set the infowindow but doesnt works

$("#place_address").bind("geocode:dragged", function(event, latLng){
  console.log('Dragged Lat: '+latLng.lat());

您的脚本对我有用，但也许您无法获得所需的结果。

最初在地图上绘制的标记是基于options.location

创建的

您已经为LatLng提供location，因此没有任何地理编码，geocode:result - 处理程序将在创建此标记时不会运行（因此信息不会是加）

可能的解决方案：触发geocode:result - 事件并传递已有的数据：

$("#place_address")
  .geocomplete(options)
    .bind("geocode:result", function(event, result){ 
      $('#logs').html('<b>'+result.formatted_address+'</b>');
      var map = $("#place_address").geocomplete("map"),
///////////////////////This code should work now as expected-STARTS 
          marker = $("#place_address").geocomplete("marker");

          //there is only a single marker, use only a single infowindow
          if(!marker.get('infowindow')){
            marker.set('infowindow',new google.maps.InfoWindow());
            google.maps.event.addListener(marker, 'click', function() {
              this.get('infowindow').open(map,this);
            });
          }
      marker.get('infowindow').close();    
      map.setZoom(15);
      map.setCenter(result.geometry.location);
      marker.setMap(map);
      marker.get('infowindow').setContent(result.formatted_address)


 ///////////////////////This code should work now as expected-ENDS  
})
//method ends
//trigger the event
.trigger('geocode:result',
         {geometry:{location:myLatlng},
          formatted_address:$('#logs').text()});
