从开放图层中的现有线获取坐标

我对开放图层很陌生，但在以下帮助下我成功绘制了线条和多边形： http://openlayers.org/dev/examples/draw-feature.html

我想知道如何从向量中获取经度和纬度？我在这里看到了一个解释：如何从openlayers获取矢量图层线点的坐标？但我太新了，无法让它发挥作用。

任何人都可以帮助我编写代码或提供示例吗？

编辑：这是解决方案。

function lineAdded(feature) {
    var nodes = feature.geometry.getVertices();

    for (var i=0; i<nodes.length; i++) {
    var lon = nodes[i].x;
    var lat = nodes[i].y;
    console.log("lon: "+lon+", lat"+lat);
    }
}
lineControl = new OpenLayers.Control.DrawFeature(vectors, path, {'featureAdded': lineAdded});

原文

I'm quite new to Open Layers but i have suceeded in drawing lines and polygones with help from: http://openlayers.org/dev/examples/draw-feature.html

I wonder how do i get the longitude and latitude from a vector?
I saw a explanation here: how to get co-ordinates of vector layer line points from openlayers?
but I'm to new to make it work.

Can anyone help me with the code or provide an example?

EDIT:
Here is the solution.

function lineAdded(feature) {
    var nodes = feature.geometry.getVertices();

    for (var i=0; i<nodes.length; i++) {
    var lon = nodes[i].x;
    var lat = nodes[i].y;
    console.log("lon: "+lon+", lat"+lat);
    }
}
lineControl = new OpenLayers.Control.DrawFeature(vectors, path, {'featureAdded': lineAdded});
