常用百度地图API接口
本文内容主要是从百度API中获取,只是为以后寻找方便.
1.点击查看一个点区域内的基础设施
<!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta name="viewport" content="initial-scale=1.0, user-scalable=no" /> <style type="text/css"> body, html,#allmap {width: 100%;height: 100%;overflow: hidden;margin:0;font-family:"微软雅黑";} </style> <script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=您的密钥"></script> <title>可视区域内的搜素</title> </head> <body> <div id="allmap"></div> </body> </html> <script type="text/javascript"> // 百度地图API功能 var map = new BMap.Map("allmap"); map.centerAndZoom(new BMap.Point(116.404, 39.915), 14); var local = new BMap.LocalSearch(map, { renderOptions:{map: map} }); local.searchInBounds("银行", map.getBounds()); map.addEventListener("dragend",function(){ map.clearOverlays(); local.searchInBounds("银行", map.getBounds()); }); </script>
2.对地图上的点添加图标,可用于对我们常用的一些
<script type="text/javascript"> // 百度地图API功能 var map = new BMap.Map("allmap"); var point = new BMap.Point(116.404, 39.915); map.centerAndZoom(point, 15); //创建小狐狸 var pt = new BMap.Point(116.417, 39.909); var myIcon = new BMap.Icon("http://lbsyun.baidu.com/jsdemo/img/fox.gif", new BMap.Size(300,157)); var marker2 = new BMap.Marker(pt,{icon:myIcon}); // 创建标注 map.addOverlay(marker2);
3.在地图上标注多个点: 先定义一个标注地图点的function , 可以从数据库中取出所有的需要标注的点,循环调用标注function.进行标注
<script type="text/javascript"> // 百度地图API功能 var map = new BMap.Map("allmap"); var point = new BMap.Point(116.404, 39.915); map.centerAndZoom(point, 15); // 编写自定义函数,创建标注 function addMarker(point){ var marker = new BMap.Marker(point); map.addOverlay(marker); } // 随机向地图添加25个标注 var bounds = map.getBounds(); var sw = bounds.getSouthWest(); var ne = bounds.getNorthEast(); var lngSpan = Math.abs(sw.lng - ne.lng); var latSpan = Math.abs(ne.lat - sw.lat); for (var i = 0; i < 25; i ++) { var point = new BMap.Point(sw.lng + lngSpan * (Math.random() * 0.7), ne.lat - latSpan * (Math.random() * 0.7)); addMarker(point); } </script>
