高德地图API常用控件的添加与删除（鹰眼、工具条、比例尺）

鹰眼插件 AMap.OverView

默认在地图右下角显示缩略图

<!DOCTYPE html>

    <meta charset="UTF-8">
    <title>map</title>
    <script type="text/javascript" src="https://webapi.amap.com/maps?v=1.4.15&key=ce3b1a3a7e67fc75810ce1ba1f83c01a&plugin=AMap.OverView"></script> 
    <style>
        *{margin:0;padding:0;list-style: none;}
        #container {width:100%; height: 100%;top:0;left:0;position: absolute; }  
    </style>
</head>
<body>
    <div id="container"></div> 

    <script>
        var map=new AMap.Map("container",{
            zoom:16,
            center:[121.549792,29.868388]
        });   

        map.addControl(new AMap.OverView({
        }));
        

    </script>    
</body>
</html>

这是不加参数的效果，右下角能看到一个小箭头，点击后出现缩略图
