php+js实现百度地图多点标注的方法

本文实例讲述了php+js实现百度地图多点标注的方法。分享给大家供大家参考，具体如下：

1.php创建json数据

$products = $this->product_db->select($where);$products_json = json_encode($products);

2.js传入json数据

类似于这样的结构

var markerArr = [{  title: "名称：广州火车站",  point: "113.264531,23.157003",  address: "广东省广州市广州火车站",  tel: "12306"}, {  title: "名称：广州塔（赤岗塔）",  point: "113.330934,23.113401",  address: "广东省广州市广州塔（赤岗塔） ",  tel: "18500000000"}, {  title: "名称：广州动物园",  point: "113.312213,23.147267",  address: "广东省广州市广州动物园",  tel: "18500000000"}, {  title: "名称：天河公园",  point: "113.372867,23.134274",  address: "广东省广州市天河公园",  tel: "18500000000"}];

js擅长处理json数据

<script>var products_json = {$products_json};// 百度地图var citymap = new citymap(products_json,'宿迁');</script>

3.处理地图

document.write('<script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=1We8imivxZnaKMujZIrlDZ0v"></script>');function citymap(markerArr, cityName){  this.markerArr = markerArr;  this.cityName = cityName;  this.initMap = function() {    this.createMap();//创建地图    this.setMapEvent();//设置地图事件    this.addMapControl();//向地图添加控件  };  this.createMap = function() {    var map = new BMap.Map("dituContent");//在百度地图容器中创建一个地图    map.centerAndZoom(cityName,'13');    window.map = map;//将map变量存储在全局    // 绘制点    for (var i = 0; i < markerArr.length; i++) {      var p0 = markerArr[i].baidu_lng;      var p1 = markerArr[i].baidu_lat;      var maker = this.addMarker(new window.BMap.Point(p0, p1),markerArr[i],i );      this.addInfoWindow(maker, markerArr[i], i);    }  };  this.addMarker = function(point,pro,index) {    var myIcon = new BMap.Icon("http://api.map.baidu.com/img/markers.png",      new BMap.Size(23, 25), {        offset: new BMap.Size(10, 25),        imageOffset: new BMap.Size(0, 0 - index * 25)      });    var marker = new BMap.Marker(point, {      icon: myIcon    });    map.addOverlay(marker);    var label = new BMap.Label(pro.name,{offset:new BMap.Size(20,-10)});    // 设置label样式    label.setStyle({       color : "#CC3333",       fontSize : "13px",       backgroundColor :"#CCFFFF",      border :"0",       fontWeight :"bold"     });    marker.setLabel(label);    return marker;  };  this.addInfoWindow = function(marker,pro) {    //pop弹窗标题     var title = '<div style="font-weight:bold;color:#CE5521;font-size:14px"><a href="?m=home&c=product&id='+ pro.id +'">' + pro.name + '</a></div>';    //pop弹窗信息     var html = [];    html.push('<table cellspacing="0" style="table-layout:fixed;width:100%;font:12px arial,simsun,sans-serif"><tbody>');    html.push('<tr>');    html.push('<td style="vertical-align:top;line-height:16px;width:38px;white-space:nowrap;word-break:keep-all">地址:</td>');    html.push('<td style="vertical-align:top;line-height:16px">' + pro.address + ' </td>');    html.push('</tr>');    html.push('</tbody></table>');    var infoWindow = new BMap.InfoWindow(html.join(""), {      title: title,      width: 200    });    var openInfoWinFun = function() {      marker.openInfoWindow(infoWindow);    };    marker.addEventListener("click", openInfoWinFun);    return openInfoWinFun;  }  this.setMapEvent = function() {    map.enableDragging();//启用地图拖拽事件，默认启用(可不写)    // map.enableScrollWheelZoom();//启用地图滚轮放大缩小    map.enableDoubleClickZoom();//启用鼠标双击放大，默认启用(可不写)    map.enableKeyboard();//启用键盘上下左右键移动地图  };  this.addMapControl = function() {    //向地图中添加缩放控件    var ctrl_nav = new BMap.NavigationControl({anchor:BMAP_ANCHOR_TOP_LEFT,type:BMAP_NAVIGATION_CONTROL_LARGE});    map.addControl(ctrl_nav);      //向地图中添加缩略图控件    var ctrl_ove = new BMap.OverviewMapControl({anchor:BMAP_ANCHOR_BOTTOM_RIGHT,isOpen:1});    map.addControl(ctrl_ove);      //向地图中添加比例尺控件    var ctrl_sca = new BMap.ScaleControl({anchor:BMAP_ANCHOR_BOTTOM_LEFT});    map.addControl(ctrl_sca);  };  this.initMap();}
