Javascript 打开图层3修改结束 问题

我已使用源和图层设置了下图所示的地图：

var features = new ol.Collection();
vectorSource = new ol.source.Vector({ features: features }),
vectorLayer = new ol.layer.Vector({
source: vectorSource
}),
styles = {
    route: new ol.style.Style({
        stroke: new ol.style.Stroke({
            width: 4,
            color: [255, 120, 0, 0.8]
    })
}),
routeSR: new ol.style.Style ({
    stroke: new ol.style.Stroke({
        width: 6,
        color: [0, 0, 0, 0.8]
    })
}),
icon: new ol.style.Style({
    image: new ol.style.Icon({
        anchor: [0.5, 1],
        src: session.icon_url
        })
    })
};



//CREATE THE MAP AND STORE IN SESSION.
session.map = new ol.Map({
    target: 'map',
    layers: [
      new ol.layer.Tile({
          source: new ol.source.OSM()
      }),
      vectorLayer
    ],
    view: new ol.View({
        center: [-5685003, -3504484],
        zoom: 11
    })
});

然后，我在地图上设置了一个单击事件，它将为该点创建一个功能，以显示一个小图标。如果这是选定的第二个点，它将在两个点之间创建一条线串。二者均如下所示：

行字符串

function TestCreateLine() {
    var CoordsFromTo = [];

    for (var i = 0; i < session.points.length; i++) {
        CoordsFromTo.push(session.points[i][0])
    }

    var line = new ol.geom.LineString(CoordsFromTo);

    var feature = new ol.Feature(line);

    feature.setStyle(styles.route);
    vectorSource.addFeature(feature);
}

它们都将作为功能添加到源中。我目前面临的问题是，我希望能够修改路线，并将新的坐标传递给我

目前，我正在使用“ModifyEnd”事件，但它似乎返回给我不止一个坐标

session.interactions.modify.on('modifyend', function (e) {
    //IF YOUR MODIFYING AN OSRM ROUTE
    if (document.getElementById('Checkbox2').checked) {

    }
    //LINE STRING ROUTE
    else {

        session.points = [];

        var changedFeatures = e.features.getArray();
        var newFeature = changedFeatures[changedFeatures.length - 1];
        var ben = newFeature.getGeometry().getCoordinates();
        vectorSource.clear()


        for (var i = 0; i < ben.length; i++) {

                var newPointInformation = [];
                newPointInformation.push((CreateGuid() + CreateGuid() + "-" + CreateGuid() + "-4" + CreateGuid().substr(0, 3) + "-" + CreateGuid() + "-" + CreateGuid() + CreateGuid() + CreateGuid()).toLowerCase());
                newPointInformation.push(ben[i]);

                session.points.push(newPointInformation);
                TestCreateFeature(newPointInformation);

        }

        TestCreateLine();
    }

});

session.interactions.modify.on（'modifyend'，函数（e）{
//如果您正在修改OSRM路由
if（document.getElementById（'Checkbox2'）。选中）{
}
//线串路由
否则{
session.points=[]；
var changedFeatures=e.features.getArray（）；
var newFeature=changedFeatures[changedFeatures.length-1]；
var ben=newFeature.getGeometry（）.getCoordinates（）；
vectorSource.clear（）
对于（变量i=0；i

正如你所看到的，我尝试清空源特性并重新构建，但问题不是所有坐标都返回给我

有人能帮忙吗

session.interactions.modify.on('modifyend', function (e) {
    //IF YOUR MODIFYING AN OSRM ROUTE
    if (document.getElementById('Checkbox2').checked) {

    }
    //LINE STRING ROUTE
    else {

        session.points = [];

        var changedFeatures = e.features.getArray();
        var newFeature = changedFeatures[changedFeatures.length - 1];
        var ben = newFeature.getGeometry().getCoordinates();
        vectorSource.clear()


        for (var i = 0; i < ben.length; i++) {

                var newPointInformation = [];
                newPointInformation.push((CreateGuid() + CreateGuid() + "-" + CreateGuid() + "-4" + CreateGuid().substr(0, 3) + "-" + CreateGuid() + "-" + CreateGuid() + CreateGuid() + CreateGuid()).toLowerCase());
                newPointInformation.push(ben[i]);

                session.points.push(newPointInformation);
                TestCreateFeature(newPointInformation);

        }

        TestCreateLine();
    }

});
