本文介绍了点击时不可能防止自动平移到标记(谷歌地图)的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我使用谷歌地图api v3,gmaps4rails和infobox,我无法弄清楚如何删除事件,包括在点击标记后自动平移地图上的地图......



标记从我的控制器发送:

  Gmaps4rails.build_markers(experience)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,标记是通过在处理函数上调用addMarkers创建的: b
$ b


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


到目前为止, c> diasbleAutoPan:true 在地图选项中,将标记设置为不可点击,然后在点击时添加一个侦听器,并做了大量的研究,但我没有发现任何这样的事情......所以我猜我做错了什么,但找不到什么!
任何帮助都会如此感谢....许多tahnks


编辑:
正如@apneadiving建议的那样,我尝试覆盖infowindow_binding方法在自定义构建器中,为了移除 @ markers.panTo 行,但地图仍然在点击它时自动居中于标记....
这里是代码对于定制生成器:


`




<$ p @ p> class @InfoBoxBuilder extends Gmaps.Google.Builders.Marker#从基础构建器继承
#覆盖方法
create_infowindow: - >
返回null除非_.isString @ args.infowindow
boxText = document.createElement(div)
boxText.setAttribute(class,'infobox-container')#to custom
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
,窗格:floatPane
,enableEventPropagation:false
infowindow_binding:=> ;
@ constructor.CURRENT_INFOWINDOW.close()if @_should_close_infowindow()
@infowindow?= @create_infowindow()
return ifinowowowow?
@ infowindow.open(@getServiceObject()。getMap(),@getServiceObject())
@ marker.infowindow?= @infowindow
@ constructor.CURRENT_INFOWINDOW = @infowindow

`
任何帮助都很棒....非常感谢您

解决方案

我也遵循了Apneadiving的建议,它对我来说工作得很好。我把以下内容assets / javascripts / gmaps4rails-infoxbox.coffee。正如你所看到的,我所做的只是将整个代码从宝石中提取出来,然后在关于平移的行中注释掉。

I use the google maps api v3, gmaps4rails and infobox and I cannot figure out how to remove the event which consist in auto panning the map on a marker as soon as it has been clicked...

The markers are sent from my controller:

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

And my map is built in js and markers are created by calling addMarkers on the handler:

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) }); });

I have tried so far to diasbleAutoPan:true in the map options, to set the markers to unclickable and then add a listener on click, and done a lot of research but I did not found anything like this... So I guess I am doing something wrong but cannot find what!! Any help would be so grateful.... many tahnks

Edit : As suggested by @apneadiving, I tried to override the infowindow_binding method within the custom builder in order to remove @markers.panTo line but the map still auto center on marker when clicking on it.... Here is the code for the custom builder :

`

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

` Any help would be great.... thank you very much

解决方案

I followed Apneadiving's suggestion as well and it worked fine for me. I put the following inside assets/javascripts/gmaps4rails-infoxbox.coffee. As you can see, all I did was pull the entire code out from the gem, then commented out the line about panning.

class @InfoBoxBuilder extends Gmaps.Google.Builders.Marker # inherit from base builder
  @CURRENT_INFOWINDOW: undefined
  @CACHE_STORE: {}

  # args:

  #   lng

  #   marker_title
  #   picture
  #     anchor: [x,y]
  #     url
  #     width
  #     height
  #   shadow
  #     anchor: [x,y]
  #     url
  #     width
  #     height
  # provider options:
  #   https://developers.google.com/maps/documentation/javascript/reference?hl=fr#MarkerOptions
  # internal_options
  #   singleInfowindow: true/false
  #   maxRandomDistance: null / int in meters
  constructor: (@args, @provider_options = {}, @internal_options = {})->
    @before_init()
    @create_marker()
    @create_infowindow_on_click()
    @after_init()

  build: ->
    @marker = new(@model_class())(@serviceObject)

  create_marker: ->
    @serviceObject = new(@primitives().marker)(@marker_options())

  create_infowindow: ->
    return null unless _.isString @args.infowindow
    new(@primitives().infowindow)({content: @args.infowindow })

  marker_options: ->
    coords = @_randomized_coordinates()
    base_options =
      title:    @args.marker_title
      position: new(@primitives().latLng)(coords[0], coords[1])
      icon:     @_get_picture('picture')
      shadow:   @_get_picture('shadow')
    _.extend @provider_options, base_options

  create_infowindow_on_click: ->
    @addListener 'click', @infowindow_binding

  infowindow_binding: =>
    @constructor.CURRENT_INFOWINDOW.close() if @_should_close_infowindow()
    # @marker.panTo()
    @infowindow ?= @create_infowindow()

    return unless @infowindow?

    @infowindow.open( @getServiceObject().getMap(), @getServiceObject())
    @marker.infowindow ?= @infowindow

  _create_or_retrieve_image: (picture_args) ->
    if @constructor.CACHE_STORE[picture_args.url] is undefined
      @constructor.CACHE_STORE[picture_args.url] = new(@primitives().markerImage)(picture_args.url, picture_args.size, picture_args.origin, picture_args.anchor , picture_args.scaledSize)

    @constructor.CACHE_STORE[picture_args.url]

  _picture_args: (picture_name)->
    {
      url:        @args[picture_name].url

      size:       new(@primitives().size)(@args[picture_name].width, @args[picture_name].height)
      scaledSize: null
      origin:     null
    }

  _createImageAnchorPosition : (anchorLocation) ->
    return null unless _.isArray anchorLocation
    new(@primitives().point)(anchorLocation[0], anchorLocation[1])

  _should_close_infowindow: ->
    @internal_options.singleInfowindow and @constructor.CURRENT_INFOWINDOW?

  _randomized_coordinates: ->
    return [@args.lat, @args.lng] unless _.isNumber(@internal_options.maxRandomDistance)

    #gives a value between -1 and 1
    random = -> (Math.random() * 2 - 1)
    dx  = @internal_options.maxRandomDistance * random()
    dy  = @internal_options.maxRandomDistance * random()
    Lat = parseFloat(@args.lat) + (180/Math.PI)*(dy/6378137)
    Lng = parseFloat(@args.lng) + ( 90/Math.PI)*(dx/6378137)/Math.cos(@args.lat)
    return [Lat, Lng]
