scripts may close only the windows that were opened by them.

调用window.close() 无效 并在控制台看到如下警告

scripts may close only the windows that were opened by them.

可使用以下代码

let userAgent = navigator.userAgent;if (userAgent.indexOf("Firefox") != -1 || userAgent.indexOf("Chrome") !=-1) {location.href="about:blank";} else {window.opener = null;window.open('', '_self');}window.close();
