[英]How to create a translucent overlay using JavaScript in ReactJS?
问题描述
In ReactJS project, I have an API request and once I make it, I would like to render a translucent overlay on the current webpage with Material UI's progress indicator ( http://www.material-ui.com/#/components/circular-progress )on top of the translucent overlay, and after I get a response back, would like for the translucent overlay with the progress indicator to go away. 
在ReactJS项目中，我有一个API请求，一旦完成，我想用Material UI的进度指示器在当前网页上渲染一个半透明的覆盖层（ http://www.material-ui.com/#/components/circular -progress ），然后返回响应后，希望带有进度指示器的半透明覆盖物消失。
How can I go about doing so? 我该怎么做呢？ Any guidance or insight would be greatly appreciated. 任何指导或见解将不胜感激。 Thank you. 谢谢。
