javascript - 从 AJAX 在 javascript 中创建列表

Question

你好，我有一个函数可以从 xml 数据中获取信息并在谷歌地图上打印标记 我的问题是我想在一点到另一点之间创建一条路径 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
                        });`

所以我想将我检索到的日期添加到列表中并绘制一条线，如下代码所示:

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)]
                                       });`

我想要行 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
                });
                ...
