How do I detect IE and Edge browser?

问题

Can't get Parallax working properly in IE or Microsoft Edge. I've looked in forums and haven't found a solution to the problem. I've come up with hopefully a solution for now. I want to make a message appear if the user is using IE or Edge. Not sure how I can detect that the browser being used is one or the either.

Here is some javascript code I'm trying to work with:

<script src="https://github.com/ded/bowser/blob/master/src/bowser.js"></script>

    // Determine Browser Used
browser = require('bowser').browser; becomes browser = require('bowser');
if (bowser.msie || bowser.msedge) {
  alert('Hello Microsoft User');
}

Any help would be appreciated or if there is a better solution.

I doubt you really need to detect the browser. But here it is anyway (don't really need to use a library):

// detect IE8 and above, and edge
if (document.documentMode || /Edge/.test(navigator.userAgent)) {
    alert('Hello Microsoft User!');
}

For me better this:

var uA = window.navigator.userAgent,
    isIE = /msie\s|trident\/|edge\//i.test(uA) && !!(document.uniqueID || document.documentMode || window.ActiveXObject || window.MSInputMethodContext),
    checkVersion = (isIE && +(/(edge\/|rv:|msie\s)([\d.]+)/i.exec(uA)[2])) || NaN;
