Cesium实现被点击的省边界变色,生成示例给我看看

好的，以下是Cesium实现被点击的省边界变色的示例代码：

var viewer = new Cesium.Viewer('cesiumContainer');
var promise = Cesium.GeoJsonDataSource.load('path/to/province/geojson/data');
promise.then(function(dataSource) {
  viewer.dataSources.add(dataSource);
  var entities = dataSource.entities.values;
  for (var i = 0; i < entities.length; i++) {
    var entity = entities[i];
    entity.polygon.material = Cesium.Color.fromRandom({
      alpha: 0.6
    });
    entity.polygon.outline = false;
    entity.polygon.fill = true;
    entity.polygon.extrudedHeight = 0;
    entity.polygon.classificationType = Cesium.ClassificationType.TERRAIN;
    entity.polygon.onmouseup = function(entity) {
      return function(e) {
        entity.polygon.material = Cesium.Color.RED;
      }
    }(entity);
  }
});

希望能帮到您！接下来有什么问题可以继续问我哦~
