在 Vue.js 2.x 中使用 Cesium 实现点击按钮时出现分屏效果,你可以使用 Vue.js 的生命周期函数和 Cesium 的 `Scene` 对象和 `Camera` 对象。
以下是一个简单的示例代码:
```vue
<template>
<div>
<div ref="cesiumContainer" class="cesiumContainer"></div>
<div class="buttonContainer">
<button @click="splitScreen">Split Screen</button>
</div>
</div>
</template>
<script>
import * as Cesium from "cesium";
export default {
data() {
return {
viewer1: null,
viewer2: null,
camera1: null,
camera2: null,
scene1: null,
scene2: null,
isSplit: false
};
},
mounted() {
this.init();
},
methods: {
init() {
this.viewer1 = new Cesium.Viewer(this.$refs.cesiumContainer, {
animation: false,
timeline: false
});
this.viewer2 = new Cesium.Viewer(this.$refs.cesiumContainer, {
animation: false,
timeline: false
});
this.viewer2.container.style.position = "absolute";
this.viewer2.container.style.top = "50%";
this.viewer2.container.style.height = "50%";
this.scene1 = this.viewer1.scene;
this.scene2 = this.viewer2.scene;
this.camera1 = this.scene1.camera;
this.camera2 = this.scene2.camera;
this.scene1.postRender.addEventListener(() => {
if (this.isSplit) {
this.camera2.setView({
destination: this.camera1.position,
orientation: this.camera1.headingPitchRoll
});
}
});
this.scene2.postRender.addEventListener(() => {
if (this.isSplit) {
this.camera1.setView({
destination: this.camera2.position,
orientation: this.camera2.headingPitchRoll
});
}
});
},
splitScreen() {
this.isSplit = !this.isSplit;
if (this.isSplit) {
this.viewer1.container.style.width = "50%";
this.viewer1.container.style.height = "100%";
this.viewer2.container.style.width = "50%";
this.viewer2.container.style.height = "50%";
this.viewer2.container.style.left = "50%";
this.viewer2.container.style.top = "0";
this.viewer2.container.style.zIndex = "0";
} else {
this.viewer1.container.style.width = "100%";
this.viewer1.container.style.height = "100%";
this.viewer2.container.style.width = "0";
this.viewer2.container.style.height = "0";
this.viewer2.container.style.left = "100%";
this.viewer2.container.style.top = "100%";
this.viewer2.container.style.zIndex = "-1";
}
}
}
};
</script>
<style scoped>
.cesiumContainer {
width: 100%;
height: 100%;
margin: 0;
padding: 0;
overflow: hidden;
position: absolute;
}
.buttonContainer {
position: absolute;
top: 10px;
left: 10px;
z-index: 1;
}
button {
padding: 10px;
font-size: 16px;
}
</style>
```
在此示例中,我们使用 `ref` 属性将 `div` 元素设置为 Cesium 容器,并在 `mounted` 生命周期函数中初始化 `Viewer` 对象和相应的 `Scene` 对象和 `Camera` 对象。当点击“Split Screen”按钮时,我们使用 `isSplit` 变量来控制分屏状态,然后根据状态设置两个 `Viewer` 对象的样式。
我们还使用 `Scene` 对象的 `postRender` 事件来监听每个 `Viewer` 对象的渲染,然后使用 `Camera` 对象的 `setView` 方法将其视图设置为分屏视图。
需要注意的是,这只是一个简单的示例代码,如果你想要实现更复杂的分屏效果,你需要对代码进行适当的修改。
