代码如下：
var dataSources = viewer.dataSources;
for (var i = 0; i < viewer.dataSources.length; i++) {
    if (viewer.dataSources.get(i).name.indexOf("dz")!= -1) {
        viewer.dataSources.remove(viewer.dataSources.get(i));
        i--;
    }
}

Answer 1

您好，remove(dataSource, destroy) ,移除并销毁试试

另外看看viewer.dataSources.get(i)获取到数据源没有

你好，我试了一下，destroy为true还是不行，viewer.datasources.get(i)是可以获取到datasource的

我测试了一下，没问题，你自己检查你的循环有没有问题，存不存在越界等问题

附上我的测试代码：

	var viewer=null;
   function onload(Cesium) {
    viewer = new Cesium.Viewer('cesiumContainer', {
    sceneMode : Cesium.SceneMode.SCENE2D,
    timeline : false,
    animation : false
});

var dataSource = Cesium.GeoJsonDataSource.load('./data/simplestyles.geojson');
viewer.dataSources.add(dataSource);
console.log(viewer.dataSources);
viewer.zoomTo(dataSource);
console.log(viewer.dataSources);
}
$('#toolbar').show();
$('#loadingbar').remove();
$('#addgltf').click(function(){
    viewer.dataSources.remove(viewer.dataSources.get(0));
}) 

Answer 2

我也遇到了，请问你解决该问题了吗

Answer 3

viewer.dataSources.remove(viewer.dataSources.get(i),false);

remove第二个参数传个false
