Check if user is using IE

Question

I am calling a function like the one below by click on divs with a certain class.

Is there a way I can check when starting the function if a user is using Internet

Answer 1

Use below JavaScript method :

function msieversion() 
{
    var ua = window.navigator.userAgent;
    var msie = ua.indexOf("MSIE ");

    if (msie > 0) // If Internet Explorer, return version number
    {
        alert(parseInt(ua.substring(msie + 5, ua.indexOf(".", msie))));
    }
    else  // If another browser, return 0
    {
        alert('otherbrowser');
    }

    return false;
}

Update : (IE 11 support)

function msieversion() {

    var ua = window.navigator.userAgent;
    var msie = ua.indexOf("MSIE ");

    if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./))  // If Internet Explorer, return version number
    {
        alert(parseInt(ua.substring(msie + 5, ua.indexOf(".", msie))));
    }
    else  // If another browser, return 0
    {
        alert('otherbrowser');
    }

    return false;
}
