上代码：

    1. export const isPc = () => {
    2.   const ua = navigator.userAgent
    3.   const moveDevices = [
    4.     "Android",
    5.     "iPhone",
    6.     "SymbianOS",
    7.     "Windows Phone",
    8.     "iPad",
    9.     "iPod"
    10.   ]
    11.   let flag = true;
    12.   for (let i = 0; i < moveDevices.length; i++) {
    13.     if (ua.indexOf(moveDevices[i]) !== -1) {
    14.       flag = false;
    15.       break
    16.     }
    17.   }
    18.   return flag
    19. }
    21. export const closeCurWebPage = () => {
    22.   if (!isPc()) {
    23.     window.opener = null
    24.     window.open("about:blank", "_self", "").close()
    25.   }
    26.   if (navigator.userAgent.indexOf(Firefox) !== -1 || navigator.userAgent.indexOf("Chrome") !== -1) {
    27.     // 浏览器键入url方式打开的网页
    28.     window.location.href = "about:blank"
    29.     window.close()
    30.   } else {
    31.     // 脚本打开的网页
    32.     window.opener = null
    33.     window.open("about:blank", "_self", "")
    34.     window.close()
