Google Maps Javascript V3 API with Rhomobile


I am trying to load Google map javascript V3 API in rhomobile. but unable to do so. I have Used below code in map.erb:

<div data-role="header" data-position="inline">
  <h1>Login</h1>
</div>

<div data-role="content">
  <form method="POST" action="<%= url_for :action => :do_login %>">
    <% if @msg %>
        <div class="error-message"><%= @msg %></div>
    <% end %>

    <div data-role="fieldcontain">
      <label for="login" class="itemLabel">Login</label>
      <input type="text" id="login" name="login" class="itemValue" <%= placeholder("Login") %> />
    </div>
    <div data-role="fieldcontain">
      <label for="password">Password</label>
      <input type="password" id="password" name="password" class="itemValue" <%= placeholder("Password") %> />
    </div>
    <input type="submit" value="Login"/>
  </form>
</div>
<ul>
  <li>
    <a href = "<% url_for :action =>:map_it %>">
      <span class="title">Show On Map</span>
      <span class="disclosure_indicator"></span>
    </a>

  </li>
  <li>
        <a href = "<% url_for :action =>:myMaps %>">
                          <span class="title">Show On Map</span>
                          <span class="disclosure_indicator"></span>
                        </a>
  </li>
</ul>

and called it using controller. But nothing happens when I click on the link which redirects to map.erb.

Edit: I have changed the Complete program. This is not working in RhoSimulator, but working on phone(Android). The Only problem i am facing on phone is Map is not getting loaded when i go to the map screen. But when i refresh the screen it's getting loaded. map.erb :-

 <div data-role="header" data-position="inline">
   <h1>Maps</h1>
 </div>

 <div data-role="content" id="pageMaps">
  <script type="text/javascript"> 
  $(function{alert("test");}) 
  </script> 
    <script type="text/javascript" 
        src="http://maps.google.com/maps/api/js?sensor=true"> 
    </script> 
    <script type="text/javascript"> 
    alert("Hello");
         function initialize() { 
        var latlng = new google.maps.LatLng(-34.397, 150.644); 
        var myOptions = { 
          zoom: 8, 
          center: latlng, 
          mapTypeId: google.maps.MapTypeId.ROADMAP 
        }; 
        var map = new 
    google.maps.Map(document.getElementById("map_canvas"), 
            myOptions); 
      } 

      $('#pageMaps').live('pageshow', function(){
        initialize();
      });

    </script> 
    <div id="map_canvas" style="width:200px; height:300px;"></div> 
 </div>

controller.rb

def myMaps
  @msg = "Map is loading."
  render :action => :map
end

and a link in login.erb

        <div data-role="content">
           <ul data-role="listview">
             <li><a href="<%= url_for :action =>:myMaps %>">Maps</a></li>
           </ul>
         </div>

Solution

  • I think that getting the map page only when you reload the map.erb page is due to jQuery Mobile way of loading pages using AJAX.

    You can force a complete reload of your page using the data-ajax="false" in the login.erb:

    <div data-role="content">
      <ul data-role="listview">
        <li><a href="<%= url_for :action =>:myMaps %>" data-ajax="false">Maps</a></li>
      </ul>
    </div>
    

    Take a look at jQuery Mobile docs for more informations.
