# 坐标遍历(coordEach)
> npm install @turf/meta
Iterate over coordinates in any GeoJSON object, similar to Array.forEach() 遍历任何GeoJSON对象中的坐标,类似于
Array.forEach()
参数
参数 | 类型 | 描述 |
---|---|---|
geojson | (FeatureCollection|Feature|Geometry) | 任意 GeoJSON 对象 |
callback | Function | 回调,参数依次是 currentCoord、coordIndex、featureIndex、multiFeatureIndex |
excludeWrapCoord | boolean | 是否包含最后一个坐标对(针对闭环线、面要素等坐标是首位闭合的情况),默认为 false |
返回
undefined - undefined
示例
var features = turf.featureCollection([
turf.point([26, 37], {"foo": "bar"}),
turf.point([36, 53], {"hello": "world"})
]);
turf.coordEach(features, function (currentCoord, coordIndex, featureIndex, multiFeatureIndex, geometryIndex) {
//=currentCoord
//=coordIndex
//=featureIndex
//=multiFeatureIndex
//=geometryIndex
});
