百度地图坐标查询
http://api.map.baidu.com/lbsapi/getpoint/index.html
首先去申请一个API key，获取API key后在页面调用
申请地址：http://lbsyun.baidu.com/apiconsole/key?application=key
<script src="http://api.map.baidu.com/api?v=2.0&ak=8cprupV34TG3GIxu6CnRE5Ua&service=true" type="text/javascript"></script>
调用api的方法函数
var map = null;
$(function(){
map = new BMap.Map("map");
var point = new BMap.Point(x坐标,y坐标);
map.centerAndZoom(point, 15);
//放大控件
map.addControl(new BMap.NavigationControl());
map.enableScrollWheelZoom();
dingwei("地点标题","地址","电话",x坐标,y坐标);
map.setCurrentCity("广州");
})
//定位
function dingwei(title,tel,add,x,y){
var points = new BMap.Point(x,y);
map.centerAndZoom(points, 15);
var opts={width:150,height:60,title:title}
var infoWindow=new BMap.InfoWindow("<br>地址："+add+"<br>电话："+tel,opts);
infoWindow.setWidth(300);
infoWindow.setHeight(150);
map.openInfoWindow(infoWindow,points);
}
页面容器
<div class="map" id="map"></div>
css
<style type="text/css">
.map {
width: 730px;
height: 336px;
margin: 0px auto;
border: 5px solid #FFF;
}
</style>
