如何动态地从 kepler.gl 中删除所有地图图层?

How to remove all map layers from kepler.gl dynamically?

我在每个选项上添加了 div 和 drodownwn,我在 reactjs 中使用 addDatatoMap 上传了 geojson 数据。 每次我选择该选项时,都会上传相应的图层, 但我无法删除之前的图层, 所以任何重置/清除地图层的代码或示例

经过这么多研究我找到了解决方案,所以发布它以节省其他人的时间

import KeplerGlSchema from 'kepler.gl/schemas';
import { visStateUpdaters } from 'kepler.gl/reducers';

// // Clear Uploaded Data
RemoveUploadedData() {
// // returns uploaded Data on map
const dataToSave = 
KeplerGlSchema.getDatasetToSave(this.props.demo.keplerGl.map);
console.log('dataToSave', dataToSave);

// // returns uploaded layer config on map
const configToSave = 
KeplerGlSchema.getConfigToSave(this.props.demo.keplerGl.map);
console.log('configToSave', configToSave);

var layerConfigs = configToSave.config.visState.layers;

// // Removed each uploaded layers
if (configToSave && layerConfigs.length > 0) {
    for (var i = 0; i < layerConfigs.length; i++) {
        this.props.demo.keplerGl.map.visState = 
              visStateUpdaters.removeDatasetUpdater(            
              this.props.demo.keplerGl.map.visState,
            { key: dataToSave[i].data.id }
         )
       }
     }
   }
