How to detect my browser version and operating system using JavaScript?

Question

I have tried using the code below but it only display results in Chrome and Mozilla not working in IE6.

Answer 1

To get the new Microsoft Edge based on a Mozilla core add:

else if ((verOffset=nAgt.indexOf("Edg"))!=-1) {
 browserName = "Microsoft Edge";
 fullVersion = nAgt.substring(verOffset+5);
}

before

// In Chrome, the true version is after "Chrome" 
else if ((verOffset=nAgt.indexOf("Chrome"))!=-1) {
 browserName = "Chrome";
 fullVersion = nAgt.substring(verOffset+7);
}
