我在Vuetify和IE11上经历了一场噩梦，想重定向到一个基本的HTML页面，该页面显示不支持IE 11或IE 10。我在大学工作，IE11仍然是标准，因为它与我们的电子病历系统紧密集成。 IE11是标准配置，因此，如果在电子邮件中发送了链接，则会打开IE11。我已经在我的app.vue页面中尝试过
var compatibleBrowser = typeof Object["__defineSetter__"] === "function";
if (compatibleBrowser == false) {
alert("Sorry, this is not a compatible browser.");
}
和
if ((browser=="msie") && (version>=4)) {
if (browser=="opera"||"chrome"||"safari"||"firefox") {
location.replace("mobile_demo.php");
}
else {
location.replace("full_demo.php");
}
}
Stackoverflow和Codepen都有一些识别代码，我想将其添加到vue应用程序中。问题是我不断得到SCRIPT5009：'Symbol'是未定义的文件：vuetify.js，行：19641，列：1而且我似乎无法用polyfill修复它。
所以，接下来的最好的事情是重定向
您可以检测到浏览器版本，如果IE然后呈现了您需要的某些消息。如果不是IE，则渲染vue应用。
我使用public / index.html中的JavaScript来检测浏览器，代码如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width,initial-scale=1.0">
<link rel="icon" href="<%= BASE_URL %>favicon.ico">
<title>my-vue-app</title>
</head>
<body>
<noscript>
<strong>We're sorry but my-vue-app doesn't work properly without JavaScript enabled. Please enable it to continue.</strong>
