我有一个选择交互-选择与矢量层关联的要素。我的目标是编辑要素属性并将其保存回数据库。
import Map from 'ol/Map';
import View from 'ol/View';
import Select from 'ol/interaction/Select.js';
...
this.map = new Map({
target: 'map',
view: new View({
center: this.$root.mapState.center,
zoom: this.$root.mapState.zoom
})
});
AddLayers(this.map, this.$root.map.layers, this.$root.register);
this.select = new Select();
this.map.addInteraction(this.select);
this.select.on('select', function(e) {
e.target.getFeatures().forEach(function(feature) {
alert('Selected ' + feature.getId());
});
});
如何从要素中获取图层?
从2015年开始对this问题的答案似乎很奏效。
我真的必须经历所有这些吗?在OpenLayers 2中,我将引用feature.layer-此功能似乎已消失。
答案 0 :(得分:0)
感谢@Mike,我在功能中的循环中添加了me.select.getLayer(feature)
。
完整的解决方案是:
import Map from 'ol/Map';
import View from 'ol/View';
import Select from 'ol/interaction/Select.js';
...
this.map = new Map({
target: 'map',
view: new View({
center: this.$root.mapState.center,
zoom: this.$root.mapState.zoom
})
});
AddLayers(this.map, this.$root.map.layers, this.$root.register);
this.select = new Select();
this.map.addInteraction(this.select);
var me = this;
this.select.on('select', function(e) {
e.target.getFeatures().forEach(function(feature) {
var layer = me.select.getLayer(feature);
alert('Selected ' + feature.getId());
});
});
