如何借助JavaScript中的数组对象在OpenStreetMap上绘制多段线？

我想借助marker array object在OpenStreetMap上绘制多段线 目前，我从数据库中选择了所有标记（经度、纬度）值，并在此标记的基础上，绘制多段线以显示特定用户的路线

[window.onload = function GetOSMMap() {
    map = new OpenLayers.Map("dvMap");
    var mapnik = new OpenLayers.Layer.OSM();
    var fromProjection = new OpenLayers.Projection("EPSG:4326"); // Transform from WGS 1984
    var toProjection = new OpenLayers.Projection("EPSG:900913"); // to Spherical Mercator Projection                                                                                            
    var zoom = 15;
    map.addLayer(mapnik);

    var marker = new OpenLayers.Layer.Markers("Markers");

    for (i = 0; i < markers.length; i++) {
        var data = markers\[i\]
        var lonLat = new OpenLayers.LonLat(data.lng, data.lat).transform(new OpenLayers.Projection("EPSG:4326"), map.getProjectionObject());

        map.addLayer(marker);
        marker.addMarker(new OpenLayers.Marker(lonLat));
        map.setCenter(lonLat, zoom);

    }
    var lineLayer = new OpenLayers.Layer.Vector("Line Layer");

    map.addLayer(lineLayer);
    map.addControl(new OpenLayers.Control.DrawFeature(lineLayer, OpenLayers.Handler.Path));
    var points = new Array(
        new OpenLayers.Geometry.Point(data.lng, data.lat)
    );
    points.push(lonLat);
    var line = new OpenLayers.Geometry.LineString(points);

    var style = {
        strokeColor: '#0000ff',
        strokeOpacity: 0.5,
        strokeWidth: 5
    };

    var lineFeature = new OpenLayers.Feature.Vector(line, null, style);
    lineLayer.addFeatures(\[lineFeature\]);

}]

[window.onload=函数GetOSMMap（）{
map=新的OpenLayers.map（“dvMap”）；
var mapnik=new OpenLayers.Layer.OSM（）；
var fromProjection=newopenlayers.Projection（“EPSG:4326”）；//从WGS 1984转换
var toProjection=new OpenLayers.Projection（“EPSG:900913”）；//到球形墨卡托投影
var=15；
map.addLayer（mapnik）；
var marker=新的OpenLayers.Layer.Markers（“Markers”）；
对于（i=0；i

1）更改数组变量声明创建数组的简单对象
变量点=新数组( 新OpenLayers.Geometry.Point（data.lng，data.lat） ); 到 var points=新数组（）； 2） 点的变化。推（lonLat）；到 push（新的OpenLayers.Geometry.Point（data.lng，data.lat））；并通过将这行写在循环标记下。 3） 多加一行 line.transform（新OpenLayers.Projection（“EPSG:4326”）、新OpenLayers.Projection（“EPSG:900913”）
