实现代码：

export function show1() {map.setOptions({scene: {backgroundType: "image",backgroundImage: "url(//data.mars3d.cn/img/busines/background1.jpg)"}})
}export function show2() {map.setOptions({scene: {backgroundType: "color",backgroundColor: "red"}})
}export function show3() {map.setOptions({scene: {backgroundType: "skybox",skyBox: {sources: {negativeX: "//data.mars3d.cn/img/skybox/3/tycho2t3_80_mx.jpg",negativeY: "//data.mars3d.cn/img/skybox/3/tycho2t3_80_my.jpg",negativeZ: "//data.mars3d.cn/img/skybox/3/tycho2t3_80_mz.jpg",positiveX: "//data.mars3d.cn/img/skybox/3/tycho2t3_80_px.jpg",positiveY: "//data.mars3d.cn/img/skybox/3/tycho2t3_80_py.jpg",positiveZ: "//data.mars3d.cn/img/skybox/3/tycho2t3_80_pz.jpg"}}}})}

效果：

原始写法：

export function show1() {// map.container.style.backgroundImage = "url(//data.mars3d.cn/img/busines/background1.jpg)"map.setOptions({scene: {backgroundImage: "url(//data.mars3d.cn/img/busines/background1.jpg)"}})
}export function show2() {// map.container.style.backgroundImage = "url(//data.mars3d.cn/img/map/world/world.jpg)"map.setOptions({scene: {backgroundColor: 'red',}})
}export function show3() {// map.container.style.backgroundImage = "url(//data.mars3d.cn/img/busines/background2.jpg)"map.scene.skyBox = new Cesium.SkyBox({sources: {negativeX: "//data.mars3d.cn/img/skybox/3/tycho2t3_80_mx.jpg",negativeY: "//data.mars3d.cn/img/skybox/3/tycho2t3_80_my.jpg",negativeZ: "//data.mars3d.cn/img/skybox/3/tycho2t3_80_mz.jpg",positiveX: "//data.mars3d.cn/img/skybox/3/tycho2t3_80_px.jpg",positiveY: "//data.mars3d.cn/img/skybox/3/tycho2t3_80_py.jpg",positiveZ: "//data.mars3d.cn/img/skybox/3/tycho2t3_80_pz.jpg"}})
