高德地图JS API 开发小结

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">周边查询</a>]');
                    linkline.push('[<a href="/newhouses/detail/15" class="d4d4" target="_blank">楼盘快讯</a>]');
                    var infowindow = new amap.infowindow({

                        size: new amap.size(410, 0),
                        offset: new amap.pixel(320, -280)
                    });

                    //构建自定义信息窗体
                    function createinfowindow() {

                        //可以通过下面的方式修改自定义窗体的宽高
                        //info.style.width = "400px";

                    //关闭信息窗体
                    function closeinfowindow() {
                        map.clearinfowindow();
                    }

 

给多个自定义点标记添加自定义信息窗体：

　　　　  var markets=[];
                $.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
