百度地圖多點標注實現

1.php創建json數據

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

2.js傳入json數據

類似於這樣的結構

var markerArr = [{
    title: "名稱：廣州火車站",
    point: "113.264531,23.157003",
    address: "廣東省廣州市廣州火車站",
    tel: "12306"
}, {
    title: "名稱：廣州塔（赤崗塔）",
    point: "113.330934,23.113401",
    address: "廣東省廣州市廣州塔（赤崗塔） ",
    tel: "18500000000"
}, {
    title: "名稱：廣州動物園",
    point: "113.312213,23.147267",
    address: "廣東省廣州市廣州動物園",
    tel: "18500000000"
}, {
    title: "名稱：天河公園",
    point: "113.372867,23.134274",
    address: "廣東省廣州市天河公園",
    tel: "18500000000"
}];

js擅長處理json數據

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

3.處理地圖

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();//創建地圖
        this.setMapEvent();//設置地圖事件
        this.addMapControl();//向地圖添加控件
    };
    this.createMap = function() {
        var map = new BMap.Map("dituContent");//在百度地圖容器中創建一個地圖
        map.centerAndZoom(cityName,'13');

        window.map = map;//將map變量存儲在全局

        // 繪制點
        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)});
        // 設置label樣式
        label.setStyle({ 
            color : "#CC3333", 
            fontSize : "13px", 
            backgroundColor :"#CCFFFF",
            border :"0", 
            fontWeight :"bold" 
        });
        marker.setLabel(label);
        return marker;
    };

    this.addInfoWindow = function(marker,pro) {
        //pop彈窗標題  
        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彈窗信息  
        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">' + 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();//啟用地圖拖拽事件，默認啟用(可不寫)
        // map.enableScrollWheelZoom();//啟用地圖滾輪放大縮小
        map.enableDoubleClickZoom();//啟用鼠標雙擊放大，默認啟用(可不寫)
        map.enableKeyboard();//啟用鍵盤上下左右鍵移動地圖
    };
    this.addMapControl = function() {
        //向地圖中添加縮放控件
        var ctrl_nav = new BMap.NavigationControl({anchor:BMAP_ANCHOR_TOP_LEFT,type:BMAP_NAVIGATION_CONTROL_LARGE});
        map.addControl(ctrl_nav);
            //向地圖中添加縮略圖控件
        var ctrl_ove = new BMap.OverviewMapControl({anchor:BMAP_ANCHOR_BOTTOM_RIGHT,isOpen:1});
        map.addControl(ctrl_ove);
            //向地圖中添加比例尺控件
        var ctrl_sca = new BMap.ScaleControl({anchor:BMAP_ANCHOR_BOTTOM_LEFT});
        map.addControl(ctrl_sca);
    };
    
    this.initMap();
