Check for IE 10 [duplicate]

Answer 1

Here's a method for getting the current IE or the IE Version:

function IE(v) {
  return RegExp('msie' + (!isNaN(v)?('\\s'+v):''), 'i').test(navigator.userAgent);
}

Here's how you can use it:

if(IE())   alert('Internet Explorer!');
if(IE(10)) alert('Internet Explorer 10!');
