这里的新Mac用户 - 有没有办法在OSX上扩展Eclipse树视图（包浏览器，搜索结果等）一次一个级别？我已经做了很多搜索，而且我开始拔头发了。）
在Windows / Linux中，我使用:coffeescript
window.createPostcodeMarker = (postcode) ->
marker = new google.maps.Marker
draggable: false
raiseOnDrag: false
position: postcode.position
map: map
tooltip: postcode.name
icon:
path: google.maps.SymbolPath.CIRCLE
fillOpacity: 1
strokeOpacity: 1
strokeColor: postcode.stroke_color
strokeWeight: 1
scale: 3
fillColor: postcode.stroke_color
circle = new google.maps.Circle
map: map
radius: postcode.radius
fillColor: postcode.fill_color
strokeColor: postcode.stroke_color
strokeWeight: 1
strokeOpacity: 0.8
circle.bindTo('center', marker, 'position')
marker
window.createAreaMarker = (area) ->
marker = new google.maps.Marker
draggable: false
raiseOnDrag: false
position: area.position
map: map
tooltip: area.name
icon:
path: google.maps.SymbolPath.CIRCLE
fillOpacity: 0.3
strokeOpacity: 0.3
strokeColor: area.stroke_color
strokeWeight: 1
scale: 0
fillColor: area.stroke_color
circle = new google.maps.Circle
map: map
radius: area.radius
fillColor: area.fill_color
strokeColor: area.stroke_color
strokeWeight: 1
strokeOpacity: 0.3
circle.bindTo('center', marker, 'position')
marker
window.googleMapsInitializePostcodesMap = ->
if PageData?.postcodesData?
window.bounds = new google.maps.LatLngBounds()
window.markers = []
mapOptions =
mapTypeId: google.maps.MapTypeId.ROADMAP
maxZoom: 13
window.map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions)
# Create markers & extend bounds
for postcode in PageData.postcodesData
marker = createPostcodeMarker(postcode)
markers.push(marker)
bounds.extend(marker.position)
for area in PageData.areasData
marker = createAreaMarker(area)
markers.push(marker)
window.map.fitBounds(bounds)
= json_data_tag(@postcodes_map_data, 'postcodesData')
= json_data_tag(@areas_map_data, 'areasData')
#map-canvas{style: "width: 100%; height: 600px;"}
- content_for :footer_javascripts do
= google_maps_api_js("googleMapsInitializePostcodesMap")
（小键盘乘法）一次扩展一个级别，但无法找到等效的（或找到有效的自定义键绑定）在OSX上。
注意：我知道*会扩展/全部崩溃，但我一次只能寻找一个级别的扩展。
