1.创建地图:
<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>地图展示</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"); // 创建Map实例 map.centerAndZoom(new BMap.Point(116.404, 39.915), 11); // 初始化地图,设置中心点坐标和地图级别 //添加地图类型控件 map.addControl(new BMap.MapTypeControl({ mapTypes:[ BMAP_NORMAL_MAP, BMAP_HYBRID_MAP ]})); map.setCurrentCity("北京"); // 设置地图显示的城市 此项是必须设置的 map.enableScrollWheelZoom(true); //开启鼠标滚轮缩放</script>
2.单击获取经纬度
<style type="text/css"> body, html {width: 100%;height: 100%;margin:0;font-family:"微软雅黑";font-family:"微软雅黑";} #allmap{width:100%;height:500px;} p{margin-left:5px; font-size:14px;} </style> <script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=您的密钥"></script> <title>地图单击事件</title></head><body> <div id="allmap"></div> <p>添加点击地图监听事件，点击地图后显示当前经纬度</p></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), 11); function showInfo(e){ alert(e.point.lng + ", " + e.point.lat); } map.addEventListener("click", showInfo);
</script>
3.搜索输入提示:
<style type="text/css"> body, html{width: 100%;height: 100%;margin:0;font-family:"微软雅黑";font-size:14px;} #l-map{height:300px;width:100%;} #r-result{width:100%;} </style> <script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=您的密钥"></script> <title>关键字输入提示词条</title></head><body> <div id="l-map"></div> <div id="r-result">请输入:<input type="text" id="suggestId" size="20" value="百度" style="width:150px;" /></div> <div id="searchResultPanel" style="border:1px solid #C0C0C0;width:150px;height:auto; "></div></body></html><script type="text/javascript"> // 百度地图API功能 function G(id) { return document.getElementById(id); } var map = new BMap.Map("l-map"); map.centerAndZoom("北京",12); // 初始化地图,设置城市和地图级别。 var ac = new BMap.Autocomplete( //建立一个自动完成的对象 {"input" : "suggestId" ,"location" : map }); ac.addEventListener("onhighlight", function(e) { //鼠标放在下拉列表上的事件 var str = ""; var _value = e.fromitem.value; var value = ""; if (e.fromitem.index > -1) { value = _value.province + _value.city + _value.district + _value.street + _value.business; } str = "FromItem<br />index = " + e.fromitem.index + "<br />value = " + value; value = ""; if (e.toitem.index > -1) { _value = e.toitem.value; value = _value.province + _value.city + _value.district + _value.street + _value.business; } str += "<br />ToItem<br />index = " + e.toitem.index + "<br />value = " + value; G("searchResultPanel").innerHTML = str; }); var myValue; ac.addEventListener("on/confirm/i", function(e) { //鼠标点击下拉列表后的事件 var _value = e.item.value; myValue = _value.province + _value.city + _value.district + _value.street + _value.business; G("searchResultPanel").innerHTML ="on/confirm/i<br />index = " + e.item.index + "<br />myValue = " + myValue; setPlace(); }); function setPlace(){ map.clearOverlays(); //清除地图上所有覆盖物 function myFun(){ var pp = local.getResults().getPoi(0).point; //获取第一个智能搜索的结果 map.centerAndZoom(pp, 18); map.addOverlay(new BMap.Marker(pp)); //添加标注 } var local = new BMap.LocalSearch(map, { //智能搜索 onSearchComplete: myFun }); local.search(myValue); }
