坑梓网站建设如何建站公司是什么

1.npm 下载cesium建议指定版本下载，最新版本有兼容性问题

npm install cesium@1.95.0

2.在node_models中找到cesium将此文件下的Cesium文件复制出来放在项目的静态资源public中或者static中，获取去github上去下载zip包放在本地也可以

3.在index.html中引入js和css

<script src="./static/Cesium/Cesium.js"></script><link rel="stylesheet" href="./static/Cesium/Widgets/widgets.css">

4.现在就可以在页面中打压cesium对象了如果有输出说明引入成功可以直接使用

<div id="my-map"></div><div id="myModal" class="modal"><div id="modal-body"><div id="modelContent">.....自定义样式
<div>
</div>
</div>
