根据效果图做一个小工具栏 , 分别有驾车 ,公交和骑行三个路线类型的切换按钮 。地点输入框包括起点和终点 ,最下面要有一个可以搜索线路规划的按钮 。
思路:
1.使用new AMap.Map创建一个地图。
2.在<script>标签中引入驾车 ,公交和骑行的线路规划插件 ,插件如下
AMap.Driving,AMap.Transfer,AMap.Riding
3.为搜索按钮绑定点击事件 ,点击时先清除地图所有覆盖物 .判断搜索按钮文字。如果是“开车去”,那么就是使用AMap.Driving()方法规划驾车路线 ,并显示在地图上。
4.判断搜索按钮文字如果是”坐公交 ”,就使用AMap.Transfer()方法规划公交路线 ,并显示在地图上。
5.搜索文字按钮如果是“骑车去” ,使用AMap.Riding()方法规划骑行路线 ,并显示在地图上。
6.在点击图标按钮时 , 当前按钮变为白色 ,其他两个可以设置一个透明度效果
任务提示:
1.清除地图覆盖物的方法 : map.clearMap();
2.路线类型按钮可以使用font-awesome实现 ,如下为font-awesome地址:
https://netdna.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css
使用的图标样式:
驾车 :<i class="fa fa-car"></i>
公交 :<i class="fa fa-bus"></i>
骑行 :<i class="fa fa-bicycle"></i>
