Question

嗨，我有一个函数，可以从谷歌地图上的xml数据和打印标记中获取信息我的问题是我想创建一个点到另一个点之间的路径这是检索数据的代码
`

  $.ajax({
                type:"POST",
                url:"PipeServlet?op=1",
                dataType:"xml",
                success: function(xml){
                    // Parses the data from xml
                    var newLat, newLon, newDesc,newName;
                    $(xml).find("deal").each(function(){
                        newName = $(this).find("name").text();
                        newLat = $(this).find("lat").text();
                        newLon = $(this).find("lon").text();
                        newDesc = $(this).find("desc").text();
                        // Displaying the Coupons on the map
                        marker = new google.maps.Marker({
                            position: new google.maps.LatLng(newLat,newLon),
                            map: map,
                            title: newName,
                            html: newDesc,
                            animation: google.maps.Animation.DROP
                        });`

所以我想将我检索的日期添加到列表中并绘制如下代码中的行：

mapLine = new google.maps.Polyline({map : map,
                                        strokeColor   : '#ff0000',
                                        strokeOpacity : 0.6,
                                        strokeWeight  : 4,
                                        path:[new google.maps.LatLng(33.240547551860935,35.6153623373566),new google.maps.LatLng(33.240009149357576,35.61381738496402)]
                                       });`

我希望行path:[new google.maps.LatLng(33.240547551860935,35.6153623373566),new google.maps.LatLng(33.240009149357576,35.61381738496402)]将以动态方式创建谢谢你的帮助

构建一个数组：var path = new Array();

并在其末尾添加您的对象：path.push(position);

$.ajax({
            type:"POST",
            url:"PipeServlet?op=1",
            dataType:"xml",
            success: function(xml){
                // Parses the data from xml
                var newLat, newLon, newDesc,newName;
                var path = new Array();
                $(xml).find("deal").each(function(){
                    newName = $(this).find("name").text();
                    newLat = $(this).find("lat").text();
                    newLon = $(this).find("lon").text();
                    newDesc = $(this).find("desc").text();
                    var position = new google.maps.LatLng(newLat,newLon);
                    path.push(position);
                    // Displaying the Coupons on the map
                    marker = new google.maps.Marker({
                        position: position,
                        map: map,
                        title: newName,
                        html: newDesc,
                        animation: google.maps.Animation.DROP
                    });
                ...
                });
                mapLine = new google.maps.Polyline({map : map,
                                strokeColor   : '#ff0000',
                                strokeOpacity : 0.6,
                                strokeWeight  : 4,
                                path:path
                });
                ...
