How to detect Microsoft Chromium Edge (chredge , edgium) in Javascript

问题

'Edge 75' will be (is?) the first Chromium Based Edge browser. How can I check if this browser is Edge on Chrome ?

(What I really want to know is if the browser fully supports data-uri's - https://caniuse.com/#feat=datauri - so feature detection would even be better. If you know a way to do that, I can change the question)

You could use the window.navigator userAgent to check whether the browser is Microsoft Chromium Edge or Chrome.

Code as below:

<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)";
            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>

The Chrome browser userAgent:

mozilla/5.0 (windows nt 10.0; win64; x64) applewebkit/537.36 (khtml, like gecko) chrome/74.0.3729.169 safari/537.36

The Edge browser userAgent:

mozilla/5.0 (windows nt 10.0; win64; x64) applewebkit/537.36 (khtml, like gecko) chrome/64.0.3282.140 safari/537.36 edge/18.17763

The Microsoft Chromium Edge Dev userAgent:

mozilla/5.0 (windows nt 10.0; win64; x64) applewebkit/537.36 (khtml, like gecko) chrome/76.0.3800.0 safari/537.36 edg/76.0.167.1

The Microsoft Chromium Edge Canary userAgent:

mozilla/5.0 (windows nt 10.0; win64; x64) applewebkit/537.36 (khtml, like gecko) chrome/76.0.3800.0 safari/537.36 edg/76.0.167.1

As we can see that Microsoft Chromium Edge userAgent contains the "edg" keyword, we could use it to detect whether the browser is Chromium Edge browser or Chrome browser.
