Javascript-how does one implement the Microsoft edge browser compatibility prompt?

How does one implement such webpage prompts in the Microsoft EDGE browser? PS. It is prompted by the edge browser rather than webpage navigation. & Amp; lt; metahttp-equiv & quot; X-UA-Compatible & quot; content & quot; IE7, 9, 10, 11 & quot; & amp; gt; I tried.

Edge implements this prompt, not based on any specific page content, but Microsoft maintains a compatibility list in the cloud. Edge downloads and updates the list from time to time. As mentioned in the source code of the interface, there are several triggering conditions:

    // Returns the code for why we navigated to NeedIE:    // 0 = No transition/Error    // 1 = EMIE Site List    // 2 = Intranet Policy is set    // 3 = Cloud CV List    // 4 = Keep in Spartan

You can achieve this through JS. After detecting the Edge browser, you can jump to a page you have created, and copy the page content displayed by edge to change it. Look, it is a common HTML page. You can take out the page code and CSS file through the console, you can make the same effect on your own, even if your website is not on the Microsoft list, it can achieve the same effect, but I don't know if there will be any copyright issues. If you are worried about copyright issues, you can refer to its ideas, customize one by yourself. In fact, the magic is that "open in Internet Explorer" is actually implemented in this way:

    LaunchIE = function (automated)    {        window.external.LaunchIE(getFullUrl(), automated);    }
