如何在Openlayers3中从lon / lat画一条线

Question

How can i draw a Line in Openlayers 3? 如何在Openlayers 3中画线？

I was able to draw one with this code: 我能够用以下代码绘制一个：

var lineFeature = new ol.Feature(
                    new ol.geom.LineString([[-244780.24508882355, 5986452.183179816], [-1e6, 3e6]]));

But if i replace the coordinates with lon and lat coordinates, nothing happens. 但是，如果我将坐标替换为lon和lat坐标，则什么也不会发生。

In the API it says, i need a ol.coordinate Object for that... 在API中说，我需要一个ol.coordinate对象...

Answer 1

ol.proj.transform([7.520142, 53.803084], 'EPSG:4326', 'EPSG:3857')

worked. 工作了。 Just found it out :D 刚发现它：D
