控制单个坐标值的限制

以上实现右上角的水平范围不会超过123

获取鼠标的经纬度
longitude 经度
latitude 纬度
<!DOCTYPE html> <html lang="en"> <head><meta charset="UTF-8"><title>map</title><script type="text/javascript" src="=1.4.15&key=ce3b1a3a7e67fc75810ce1ba1f83c01a"></script> <style>*{margin:0;padding:0;}#container {width:100%; height: 100%;top:0;left:0;position: absolute; } #setZoomNode{width:400px;height:100px;background-color: #fff;border:1px solid;box-shadow:0 0 5px #000;top:20px;right:20px;position: absolute;}</style> </head> <body><div id="container"></div> <div id="setZoomNode">鼠标点击的经纬度:<span id="xy"></span></div><script>var map=new AMap.Map("container"); //通过事件设置 map.on("click",function(e){console.log(e.lnglat);xy.innerHTML=e.lnglat.lng+","+e.lnglat.lat;//同时将鼠标点击位置设置为中心点 map.setCenter([e.lnglat.lng,e.lnglat.lat]);})</script> </body> </html>
以上代码实现鼠标点击的位置作为地图的中心点
设置鼠标样式 setDefaultCursor()
