IE Behaviour Detection Library

This library is provided since IE Conditional Comments are not sufficient anymore. E.g. when a user sets up the Internet Explorer to be run at Version 10 with the Doc-Version of IE9 you can neither use IE10-CSS-Hacks nor IE9 Conditional Comments - a dilemma. This library provides a very new and simple way to check for both versions!

Preamble

In todays web development you should rather use Feature Detection instead. This JS library should only be used when you definitely - for whatever reason - need to detect a running version of Internet Explorer.

Documentation

This documentation is described by the code samples below.

Check for IE10 with IE9 HTML Standards/Support activated

IEBhvDetection.when('ie==10 && doc==9').then(function () {
  alert('Wow, stop this IE10! Dont be a liar, you act as IE9!');
});

Check for real (!) IE7

IEBhvDetection.when('ie==7 && doc==7').then(function () {
  alert('Seems to be a real IE7 with no crazy compat mode on.');
});

Check IE9 standards and below and do something else for everything above

IEBhvDetection.when('doc<=9').then(function (ieVersion, stdVersion) {
    if (ieVersion >= 10) {
        alert('Why do you use <=9 Standards when you are able to use IE10 Standards?');
    } else {
        alert('Hey you lazy user. Update your browser to at least IE10 - please!');
    }
})
    .otherie(function(){
        alert('Okay, so you\'re using IE, but not a one with doc <= 9');
    })
    .noie(function(){
        alert('Good one. We hate IE too');
    });
