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; display:none;"></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("onconfirm", 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 ="onconfirm<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);
}
</script>
