Gmaps4rails未在rails 4.0.0中定义Google Maps for Rails我遵循本教程" http://rubydoc.info/gems/gmaps4rails/2.0.4/frames "

1) Gemfile

gem 'gmaps4rails'

2) HTML on view page   
<div style='width: 800px;'>
  <div id="map" style='width: 800px; height: 400px;'></div>
</div>

3) on view page    
<script src="//maps.google.com/maps/api/js?v=3.13&amp;sensor=false&amp;libraries=geometry" type="text/javascript"></script>
<script src='//google-maps-utility-library-v3.googlecode.com/svn/tags/markerclustererplus/2.0.14/src/markerclusterer_packed.js' type='text/javascript'></script>
You'll require underscore.js too, see here: underscorejs.org/

3) Javascript source code

If you have the asset pipeline, add this:

//= require underscore
//= require gmaps/google
If you don't have asset pipeline, you'll need to import the js OR coffee files:

rails g gmaps4rails:copy_js

rails …

我正在使用 jquery 1.10

查看模板

<script>
    $(function() {
    $( "#departing_on" ).datepicker({
      dateFormat: "dd-mm-yy",
      numberOfMonths:[1,2],
      minDate: new Date() 
    });
    $( "#return_on" ).datepicker({ 
      dateFormat: "dd-mm-yy",
      numberOfMonths:[1,2],
      minDate: new Date() 
    });
    });
</script>

第一次在文本框中选择我想要默认今天的日期。如何 ？

如何从右侧拆分字符串','？从这个字符串:

str_a = "#37/1, New Ray Street, 24th mains,2nd cross, Bangalore Karnataka India"

我想要一个输出:

"#37/1, New Ray Street, 24th mains,2nd cross"

gmaps4rails 2 + rails 4

def CommonUtils.get_gmap_hash(object)
     Gmaps4rails.build_markers(object) do |user, marker|
         marker.lat user.latitude
         marker.lng user.longitude
         marker.infowindow user.location
         binding.pry
         marker.picture({
            :picture => "/img/blank.png",
            :width   => 32,
            :height  => 32
            })
         marker.json({:title => user.title})
      end
  end

这里的marker.picture方法不打自己也不知道为什么？有帮助吗？

和默认标记即将到来我想要不同的标记(blank.png).

blank.png位于assets/images/img/blank.png中
