【问题描述】：
有没有人在最新的 mapbox gl 中遇到以下错误？这发生在地图的 setFilter 时。
VM5448:227 Uncaught TypeError: Cannot read property 'id' of undefined(…)

this._checkLoaded();
var r = this.getLayer(e);
return null !== t && this._validate(validateStyle.filter, "layers." + r.id + ".filter", t) ? this : util.deepEqual(r.filter, t) ? this : (r.filter = util.clone(t),
this._updateLayer(r))
}
【问题讨论】：
-
你能发布引发错误的代码吗？即你用什么称呼
map.setFilter()。 -
我的代码类似于：mapbox.com/mapbox-gl-js/example/hover-styles代码sn-p：
Observable.fromEvent(this._map, "mousemove").subscribe( function(x: MapMouseEvent) { let features = this._map.queryRenderedFeatures(x.point, { layers: [this._layerId] }); if (features.length) { this._map.setFilter(this._layerId, ["all", ["==", "aaa", features[0].properties.aaa], ["==", "bbb", "B"]]); } else { this._map.setFilter(this._layerId, ["all", ["==", "aaa", ""], ["==", "bbb", "B"]]); } }.bind(this));
