我试图建立基于从谷歌地图API 但由于某些原因类型的只显示从请求对象内部的数组橙色不同的颜色标记 但但是console.log显示了所有不同的类型。谷歌地图API V3不同的颜色标记W/CoffeeScript的
我在做什么错?我怎样才能让标记成为不同的颜色,而不是全部是橙色的。
我写在下面的CoffeeScript:
jQuery ($) ->
map = null
infowindow = null
request = null
icons = null
specific_icon = null
marker = null
markers = null
value = null
collection = null
init =() ->
# Setup map options
mapOptions =
center: new google.maps.LatLng(47.54809, -122.1230)
zoom: 11
streetViewControl: false
panControl: false
mapTypeId: google.maps.MapTypeId.ROADMAP
zoomControlOptions:
style: google.maps.ZoomControlStyle.SMALL
mapTypeControlOptions:
mapTypeIds: [google.maps.MapTypeId.ROADMAP, 'map_style']
# Create the map with above options in div
map = new google.maps.Map(document.getElementById("map"),mapOptions)
# Drop marker in the same location
marker = new google.maps.Marker
map: map
animation: google.maps.Animation.DROP
position: mapOptions.center
icon: 'http://www.google.com/intl/en_us/mapfiles/ms/micons/red-dot.png'
# Create a request field to hold POIs
request =
location: new google.maps.LatLng(47.54809, -122.1230)
radius: 4000
types: ['store','food','park','school']
# Create the infowindow(popup over marker)
infowindow = new google.maps.InfoWindow()
# Setup places nearby search (it setups points near the center marker)
service = new google.maps.places.PlacesService(map)
service.nearbySearch(request, callback)
# Create the callback function to loop thru the places (object)
callback = (results, status) ->
if status is google.maps.places.PlacesServiceStatus.OK
for index, attrs of results
createMarker results[index]
# Create the actual markers for the looped places
createMarker = (place) ->
collection = request.types
icons =
store: 'http://www.google.com/intl/en_us/mapfiles/ms/micons/blue-dot.png'
food: 'http://www.google.com/intl/en_us/mapfiles/ms/micons/yellow-dot.png'
park: 'http://www.google.com/intl/en_us/mapfiles/ms/micons/green-dot.png'
school:'http://www.google.com/intl/en_us/mapfiles/ms/micons/orange-dot.png'
for index, value of collection
marker = new google.maps.Marker
map: map
position: place.geometry.location
icon: icons[value]
console.log value
# Create a click listener that shows a info window with places name
google.maps.event.addListener marker, 'click', ->
infowindow.setContent(place.name)
infowindow.open(map,@)
init()

什么不起作用? – Nix
如果您更改图标的顺序或删除orange-dot.png,它们仍然呈橙色吗? –
我对coffeescript不熟悉,但似乎你为同一位置上的每个地方创建了4个标记。 4个标记的最后一个标记(因此是最多也是唯一一个)将始终是橙色标记(使标记可拖动,也许你会发现其他标记在后面)。您必须从'place.types'中获取类型,并为每个位置创建一个标记,而不是迭代request.types。 –
