检测 Edge Legacy 浏览器,而不是 Edge Chromium
Detecting Edge Legacy browser, not Edge Chromium
ArcGIS 在当前和未来版本的 JavaScript API.
中弃用 IE11 和 Legacy Edge 浏览器

我想知道如何针对边缘的旧版本并提醒用户可能无法正常工作。使用:
navigator.userAgent.indexOf("Edge/") > -1 || navigator.userAgent.indexOf("Edg/") > -1;
不起作用,因为 Chromium Edge 在用户代理中仍然是边缘。还有什么我可以使用的东西可以让我区分这两者吗?
在 Edge Chromium 用户代理中是 Edg
,在 Edge Legacy 用户代理中是 Edge
。所以你只需要使用Edge
来检测Edge Legacy:
navigator.userAgent.indexOf("Edge/") > -1
您可以使用 window.navigator userAgent 来检查浏览器是 Microsoft Chromium Edge 还是 Chrome。
代码如下:
<script>
var browser = (function (agent) {
switch (true) {
case agent.indexOf("edge") > -1: return "edge";
case agent.indexOf("edg/") > -1: return "chromium based edge (dev or canary)"; // Match also / to avoid matching for the older Edge
case agent.indexOf("opr") > -1 && !!window.opr: return "opera";
case agent.indexOf("chrome") > -1 && !!window.chrome: return "chrome";
case agent.indexOf("trident") > -1: return "ie";
case agent.indexOf("firefox") > -1: return "firefox";
case agent.indexOf("safari") > -1: return "safari";
default: return "other";
}
})(window.navigator.userAgent.toLowerCase());
document.body.innerHTML = window.navigator.userAgent.toLowerCase() + "<br>" + browser;
</script>
所有版本的 Edge 在 userAgent 中都有单词“Edg”,后跟 X 并以“/”结尾,其中 X:
- 边缘=传统
- Edge = 基于铬
- EdgA = Android
- 埃德iOS = iOS
因此,只需几个正则表达式就足以识别所需的情况:
// is-edge.js v1
function isEdge(versionName, userAgent){
versionName = versionName ? versionName.toLowerCase() : 'desktop';
userAgent = userAgent ? userAgent : navigator.userAgent;
switch(versionName){
case 'desktop':
return (/Edge?\//).test(userAgent);
case 'chromium':
return (/Edg\//).test(userAgent);
case 'legacy':
return (/Edge\//).test(userAgent);
case 'mobile':
return (/Edg(A|iOS)\//).test(userAgent);
case 'android':
return (/EdgA\//).test(userAgent);
case 'ios':
return (/EdgiOS\//).test(userAgent);
};
};
使用示例:
// checks if the browser is edge on a desktop (just windows, right?)
isEdge('desktop'); // boolean
isEdge(); // boolean (empty = 'desktop')
// check if the browser is the edge and the version is based on chromium (version with the blue and green logo with waveform)
isEdge('chromium'); // boolean
// check if the browser is the edge and the version is legacy (version with blue logo similar to internet explorer)
isEdge('legacy'); // boolean
// check if the browser is the edge for android OR iOS
isEdge('mobile'); // boolean
// check if the browser is the edge for android
isEdge('android'); // boolean
// check if the browser is the edge for iOS
isEdge('ios'); // boolean
