我正在尝试加载rhomobile中的Google Map JavaScript V3 API。但无法这样做。我在 map.erb 中使用了以下代码：
<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>
并使用控制器调用它。但是，当我单击重定向到map.erb。
的链接时，什么都不会发生。rholog.txt的输出

编辑：我更改了完整的程序。这不是在Rhosimulator中工作的，而是使用电话（Android）工作。我在手机上面临的唯一问题是地图是当我进入地图屏幕时没有加载。但是，当我刷新屏幕时，它将被加载。 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
和 login.erb中的链接
<div data-role="content">
<ul data-role="listview">
<li><a href="<%= url_for :action =>:myMaps %>">Maps</a></li>
</ul>
</div>
我认为仅在重新加载地图时获得地图页面。
您可以使用 data-ajax =" false" 在login.erb中强制执行页面的完整重新加载：
<div data-role="content">
<ul data-role="listview">
<li><a href="<%= url_for :action =>:myMaps %>" data-ajax="false">Maps</a></li>
</ul>
</div>
