OpenLayers矢量要素/不可見的圖層（不渲染）
[英]OpenLayers Vector Features/Layer invisible (do not render)
問題描述
我不明白為什么樣式矢量層不可見？ 似乎沒有功能，但是為什么呢？ 這段代碼有錯誤嗎？ OSM，Google圖層是可見的，我可以在LayerSwitcher中處理它們（並且那里也存在Overlay“ Vectorlayer”）。 圖標的網址正確。

=）天哪！ 這只是愚蠢的錯誤>>> var currPoint = new OpenLayers.Geometry.Point（dislon，dislat）;
OpenLayers 3矢量圖層上所有要素的范圍？
