如何使infowindow自动显示为使用Google-Maps-for-Rails打开 [英] How do I make an infowindow automatically display as open with Google-Maps-for-Rails

问题描述

我想显示一个地图，其中infowindow框自动显示在页面上的单个标记上，就像 http://code.google.com/apis/maps/documentation/javascript/examples/map-coordinates.html

我试过编写一个回调函数来完成这个任务，但它不适合我。

 <％content_for：scripts do％> 
< script type =text / javascriptcharset =utf-8> 
 Gmaps.map.callback = function（）{
 if（Gmaps.map.markers.length == 1）{
 var marker = Gmaps.map.markers [0]; 
 var infowindow = marker.infowindow; 
 infowindow.open（Gmaps.map，marker）; 
} 
} 
< / script> 
<％end％> 
  

解决方案

您的代码几乎是完美的。除了这个：

  infowindow.open（Gmaps.map，marker）; 
  

您应该拥有：

  infowindow.open（Gmaps.map.map，marker）; 
  

确实，Gmaps.map是一个容器，Gmap.map.map是google对象。 p>

我知道这些名字很混乱。对不起。

PS：请务必在您的视图中将此代码置于gmaps调用之下。

I want to display a map with the infowindow box automatically displayed for the single marker on the page, much like http://code.google.com/apis/maps/documentation/javascript/examples/map-coordinates.html

I've tried to code a callback function to accomplish this, but it's just not working for me.

<% content_for :scripts do %>
  <script type="text/javascript" charset="utf-8">
    Gmaps.map.callback = function() {
      if (Gmaps.map.markers.length == 1) {
        var marker = Gmaps.map.markers[0];
        var infowindow = marker.infowindow;
        infowindow.open(Gmaps.map, marker);
      }
    }
  </script>
<% end %>

解决方案

Your code is almost perfect. Except that instead of:

 infowindow.open(Gmaps.map, marker);

You should have:

 infowindow.open(Gmaps.map.map, marker);

Indeed, Gmaps.map is a container, Gmap.map.map is the google object.

I know these names are confusing. Sorry.

PS: be sure to put this code under the gmaps call in your view.
