Grails google 地图可视化

Question

我正在使用 Grails 将数据从数据库推送到 Google 可视化。

有没有人对地图包足够了解，可以制作 onClick 框 [单击时的描述框]，显示 link？我在这里将它发布到 OpenShift：

http://map-whcw.rhcloud.com/address/map

普惠制代码：

<html>
<head>
<title>Map using address data from database</title>
<meta name="layout" content="main" />


 <script type="text/javascript" src="https://www.google.com/jsapi"></script>
 <script>


 google.load('visualization', '1', { 'packages': ['map'] });
 google.setOnLoadCallback(drawMap);

 function drawMap() {
 var data = google.visualization.arrayToDataTable([
   ['Address', 'Name'],
   <g:each in="${places}" var="place" status="i">["${place.fullAddress}", "${place.longDescription }"],</g:each>

   ]);

   var options = {useMapTypeControl:true, showTip: true };

  var map = new google.visualization.Map(document.getElementById('chart_div'));

map.draw(data, options);
};
 </script>

  </head>
 <body>
    <a href="#show-address" class="skip" tabindex="-1"><g:message code="default.link.skip.label" default="Skip to content&hellip;"/></a>
    <div class="nav" role="navigation">
        <ul>
            <li><a class="home" href="${createLink(uri: '/')}"><g:message code="default.home.label"/></a></li>
                <li><g:link class="list" action="index"> Address List </g:link>       </li>
                <li><g:link class="create" action="create"> New Address     </g:link></li>
        </ul>
        </div>
    <div id="chart_div"></div>
    <br><br>
