本文介绍了在 jquery mobile 中使用谷歌地图的清晰方向示例?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

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

但是示例代码很乱，无法运行:(.宜家使用它.

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

但他们也非常定制了 js，所以很难看出会发生什么.

有谁知道一个很好的简洁示例或易于遵循的实现?

解决方案

您可以在下面找到在 jQuery Mobile 页面中使用 Google 地图路线服务的基本示例.

我希望这会有所帮助.

Try to get a working jquery mobile maps direction page. There is this example listed:

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

But the example code is messy and haven't been able to get it working :(. Ikea uses it. 

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

but they also very customized the js so its very hard to see what happens.

Does anyone know of a good clean example or implementation that's easy to follow?

Below you can find a basic example of using the Google Maps directions service in a jQuery Mobile page.

UPDATE 2:

The below example locates the current position and it automatically calculates the distance and displays the route details between the current location and a static predefined destination location.
