$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
var products_json = {$products_json};// 百度地图var citymap = new citymap(products_json,宿迁);
3.处理地图
document.write(<script type="text/javascript" src=" );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./img/markers.jpg",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 =
+ pro.name +
; //pop弹窗信息var html = []; html.push(
); 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();}
