在单击标记时无法防止其自动平移到标记（Google地图）

Question

我使用了谷歌地图api v3，gmaps4rails和信息框，但我不知道如何删除该事件，该事件包括在单击鼠标后立即在地图上自动平移地图...

标记是从我的控制器发送的：

Gmaps4rails.build_markers(experiences) do |experience, marker|
  marker.lat experience.latitude
  marker.lng experience.longitude
  marker.infowindow render_to_string(partial: "/trip_experiences/infowindow.html.erb", locals: {
    experience: experience,
    trip: trip
   })
  marker.title experience.name
end

我的地图是用js构建的，并且通过在处理程序上调用addMarkers创建标记：

handler = Gmaps.build('Google', { builders: { Marker: InfoBoxBuilder} }); handler.buildMap({ provider: mapOptions, internal: { id: 'map' } }, function(){ $.get(url, function(data) { handler.removeMarkers(markers); markers = handler.addMarkers(data); setCarouselOnInfowindow(); handler.bounds.extendWith(markers); callback(false) }); });

到目前为止，我已经尝试过在地图选项diasbleAutoPan:true设置为diasbleAutoPan:true点击，然后在单击时添加一个侦听器，并进行了大量研究，但是我没有找到类似的东西……所以我想我是做错了什么，但找不到什么！ 任何帮助将不胜感激。

编辑：按照@apneadiving的建议，我尝试在自定义生成器中覆盖infowindow_binding方法，以便删除@markers.panTo行，但是单击地图时地图仍会自动以标记为中心。...这是该代码定制生成器：

`

class @InfoBoxBuilder extends Gmaps.Google.Builders.Marker # inherit from base builder
      # override method
      create_infowindow: ->
        return null unless _.isString @args.infowindow
        boxText = document.createElement("div")
        boxText.setAttribute("class", 'infobox-container') #to customize
        boxText.innerHTML = @args.infowindow
        @infowindow = new InfoBox(@infobox(boxText))
      infobox: (boxText)->
        content: boxText
        ,disableAutoPan: true
        ,pixelOffset: new google.maps.Size(-140, -40)
        ,alignBottom: true
        ,zIndex: null
        ,disableAutoPan: true
        ,closeBoxURL: ""
        ,boxStyle: {
          width: "280px"
          ,opacity: 1
        }
        ,infoBoxClearance: new google.maps.Size(100, 1000)
        ,isHidden: false
        ,pane: "floatPane"
        ,enableEventPropagation: false
        infowindow_binding: =>
          @constructor.CURRENT_INFOWINDOW.close() if @_should_close_infowindow()
          @infowindow ?= @create_infowindow()
          return unless @infowindow?
          @infowindow.open( @getServiceObject().getMap(), @getServiceObject())
          @marker.infowindow ?= @infowindow
          @constructor.CURRENT_INFOWINDOW = @infowindow

`任何帮助都会很棒。...非常感谢

我也遵循Apneadiving的建议，对我来说效果很好。 我将以下内容放入assets / javascripts / gmaps4rails-infoxbox.coffee。 如您所见，我所做的就是从gem中取出整个代码，然后注释掉有关平移的行。
