Question

我使用谷歌地图api来绘制多边形现在我想在数据库中保存多边形的顶点

我的多边形代码非常冗长，因为它是从dabase和编辑/删除模式等获取的

var paths=[
    new G.LatLng(34.051979,71.987419),
    new G.LatLng(34.051966,71.987757),
    new G.LatLng(34.051877,71.987762),
    new G.LatLng(34.051886,71.987413),
    new G.LatLng(34.051979,71.987419)
];
poly = new G.Polygon({
   clickable: false,
   paths: paths,
   map: map
});

我创建了一个编辑地图和设置地图的按钮在set map上我想通过ajax

发送getpath（）来保存DB中的顶点

$("#toggleMapEdit").click(function(){
    if($(this).html()=="Edit Map")
    {
        $(this).html("Set Map");
        poly.setEditable(true);
    }
    else
    {

        var polygonBounds = poly.getPath(); //This returns MVCArray
        /*  I have debugged this array, it containg alot of other things other than vertices
        *I want to convert this array into javascript array or json or anything else
        *that can be sent via ajax, now it is giving error
        */
        console.log(polygonBounds);
        //var myJsonString = JSON.stringify(polygonBounds);
        $.ajax({
            url:"updateProperty.php",
            type: "POST",
            data: {vertices:polygonBounds},
            success:function(e){
                alert(e);
            }
        });
        $(this).after(qry);
        poly.setEditable(false);
        $(this).html("Edit Map");
    }
    return false;
});

替换您的评论和上面的1行＆amp;使用以下代码在评论下方

 var vertices = poly.getPath();

 var polygonBounds = [];
   for (var i = 0; i < vertices.length; i++) {
   var xy = vertices.getAt(i);
   polygonBounds.push({ lat: xy.lat(), lon: xy.lng() });
  }

 console.log(polygonBounds);

希望这对你有用。
