尝试获得一个有效的 jquery 移动地图方向页面。列出了这个例子：

http://jquery-ui-map.googlecode.com/svn/trunk/demos/jquery-google-maps-mobile.html#directions_map

但是示例代码很混乱，无法让它工作:(。宜家使用它。

http://m.ikea.com/nl/nl/stores/415/map/

但他们也非常定制了 js，所以很难看到会发生什么。

有谁知道一个很好的干净示例或易于遵循的实现？

                    <div id="directions"></div>
                </div>
            </div>
        </div>      
    </body>
</html>

我希望这有帮助。
