高德地图JS API 开发小结

时间：2024-05-07 17:06:08

项目中有一块功能要用到高德地图，所以，想把编码小结一下。

首先是地图的初始化

var map = new AMap.Map("mapDiv", {
                        zoom: 17,//设置地图的缩放比例
                        center: [112.57, 37.87],//地图中心
                        resizeEnable: true //是否监控地图容器尺寸变化
                    });

Map类的其他属性，详见 https://lbs.amap.com/api/javascript-api/reference/map

自定义点标记：

　　　　　　 // 自定义点标记显示内容，HTML要素字符串
                        var markerContent = '<div class="labeledMarkerStyle2">' +
                            '<span>' +
                            '<a href="javascript:void(0);">' +
                            '<table id="tip38521" cellspacing="0" cellpadding="0" border="0">' +
                            '<tbody>' +
                            '<tr>' +
                            '<td class="s1">&nbsp;</td>' +
                            '<td class="s2">@(Model.proname)</td>' +
                            '<td class="s3">&nbsp;</td>' +
                            '</tr>' +
                            '<tr>' +
                            '<td colspan="3" class="s5"></td>' +
                            '</tr>' +
                            '</tbody>' +
                            '</table>' +
                            '</a>' +
                            '</span>' +
                            '</div>';

　　　　　　　//自定义点标记初始化
                        var marker = new AMap.Marker({
                            map: map, //要显示该marker的地图对象
                            position: [112.602951,37.816592],
                            content: markerContent, //点标记内容
                            offset: new AMap.Pixel(-13, -30) //点标记显示位置偏移量
                        });

// 将 markers 添加到地图
                        map.add(marker);

Marker类其他属性详见：https://lbs.amap.com/api/javascript-api/reference/overlay#marker

自定义信息窗体：

　　 //鼠标点击marker弹出自定义的信息窗体

　　AMap.event.addListener(marker, 'click', function () {
                            infoWindow.open(map, marker.getPosition());
                        });

　　　　　　//信息窗体显示内容

　　　　　　var title = '项目名',
                        content = [];
                    content.push('参考价格：<font style="color: #FF6600; font-family: Arial; font-size: 18px; font-weight: bold;">8256元/平方</font><br>');
                    content.push('销售状态：在售<br>');
                    content.push('物业类型：小洋房<br>');
                    content.push('所属区域：迎泽区<br>');
                    content.push('开盘时间：2017年5月9日<br>');
                    console.log(content);
                    cover = [];
                    cover.push('<a href="/NewHouses/Detail/15" target="_blank"><img src="img" width="166" height="140" border="0"></a>');

linkline = [];
                    linkline.push('[<a href="/NewHouses/Detail/15" class="D4D4" target="_blank">楼盘详情</a>]');

                    linkline.push('[<a href="/NewHouses/Detail/15" class="D4D4" target="_blank">楼盘快讯</a>]');
                    var infoWindow = new AMap.InfoWindow({

//构建自定义信息窗体

//可以通过下面的方式修改自定义窗体的宽高
                        //info.style.width = "400px";
                        // 定义顶部标题
                        var firstout = document.createElement("div");
                        firstout.className = "amap-overlays";

var outout = document.createElement("div");
                        outout.className = "amap-info outout";

var outtop = document.createElement("div");
                        outtop.className = "outtop";

给多个自定义点标记添加自定义信息窗体：

                $.post("/NewHouses/MapSearchByArea",{area:area},function(data){
                    var infoWindow = new AMap.InfoWindow({isCustom: true,size: new AMap.Size(410, 0),offset: new AMap.Pixel(320, -280)});
                    for(var i=0;i<data.length;i++){
                        if(data[i].coordinate!=""){
                            var coordinate=data[i].coordinate.split(',');
                            // 点标记显示内容，HTML要素字符串
                            var markerContent = '<div class="labeledMarkerStyle2">' +
