openlayers3 undefined不是ol.source.StaticVector上的构造函数错误 [英] openlayers3 undefined is not a constructor error on ol.source.StaticVector

问题描述

我正在使用ol v3.20.1学习openlayers3
在本书中，我已经讲到了要点，在这里我可以使用StaticVector读取/写入GeoJSON，但可以使用以下代码:

I am learning openlayers3 with ol v3.20.1
I've got to the point in the book, where I can read/write GeoJSON with StaticVector, but the following code:

var statVec = new ol.layer.Vector({
	source: new ol.source.StaticVector({
		format: new ol.format.GeoJSON(),
		projection: 'EPSG:3857'
	})
});

出现错误:

TypeError: undefined is not a constructor (evaluating 'new ol.source.StaticVector({
            format: new ol.format.GeoJSON(),
            projection: 'EPSG:3857'
        })')
    global code

我知道，自从这本书问世以来，API有了变化，但是我找不到用哪个StaticVector代替.

I realize, there was an API change, since the book came out, but I can't find what StaticVector was replaced with.

推荐答案

ol.source.StaticVector 以及其他类似的实验Vector源.关于您的问题，将 ol.source.StaticVector 替换为 ol.source.Vector .

ol.source.StaticVector along with other similar experimental Vector sources were removed in v3.5.0. Regarding your question ol.source.StaticVector is replaced with ol.source.Vector.
