How to find a client’s browser name?

In this article I will show you how can you find a client’s browser name. You can detect the browser using the JavaScript properties navigation.appName and navigation.UserAgent. The userAgent property is suitable than the navigation.appName, because some types of browser internet browser may return the value “Netscape”.  So you can check web browser using the following code.

    <script type="text/javascript"> 

        if (navigator.userAgent.indexOf("Chrome") != -1){
            alert('Chrome');
        }
        else if ((navigator.userAgent.indexOf("Opera") ||navigator.userAgent.indexOf('OPR')) != -1) {
            alert('Opera');
        } 
        else if (navigator.userAgent.indexOf("Safari") != -1){
            alert('Safari');
        }
        else if (navigator.userAgent.indexOf("Firefox") != -1){
            alert('Firefox');
        }
        else if ((navigator.userAgent.indexOf("MSIE") != -1)|| (!!document.documentMode == true)) //If above IE 10
        {
            alert('Internet Explorer');
        }
        else {
            alert('unknown browser');
        } 

    </script>
