dre*_*att 1 javascript google-maps ruby-on-rails coffeescript
我的Rails 4应用程序运行咖啡脚本来绘制谷歌地图.乍一看,它似乎不起作用.但是,当我点击浏览器刷新按钮时,地图会像冠军一样加载.这已经过测试,并且正在发生:

initialize = ->
mapOptions =
center: new google.maps.LatLng(33.51976, -101.95781)
zoom: 16
mapTypeId: google.maps.MapTypeId.ROADMAP
map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions)
myLatlng = new google.maps.LatLng(33.51976, -101.95781);
marker = new google.maps.Marker(
position: myLatlng

)
contentString = "<div id=\"info_content\">" + "<h3>Mighty Wash Amazing Autobath</h3>" + "<ul>" + "<li>6506 82nd Street, Lubbock, Texas 79424</li>" + "<li>806.553.0722</li>" + "<li>8:00am - 9:00pm</li>" + "</ul>" + "</div>"r
infowindow = new google.maps.InfoWindow(content: contentString)
google.maps.event.addListener marker, "click", ->
infowindow.open map, marker
infowindow.open(map, marker)
google.maps.event.addDomListener window, "load", initialize
位置/ index.html.erb
<div id="map-canvas"/>
这听起来很像Rails javascript仅在重新加载后才有效.建议的解决方案是用你的coffeescript包装:
ready = ->
// functions
$(document).ready(ready)
$(document).on('page:load', ready)
