How to use Javascript to detect Browser

January 27, 2018 January 27, 2018
If you want to apply different functions to each browser, you need the code to recognize the user browser. You can use following code:
    // Opera 8.0+
    var isOpera = (!!window.opr && !!opr.addons) || !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0;
    // Firefox 1.0+
    var isFirefox = typeof InstallTrigger !== 'undefined';
    // Safari 3.0+ "[object HTMLElementConstructor]" 
    var isSafari = /constructor/i.test(window.HTMLElement) || (function (p) { return p.toString() === "[object SafariRemoteNotification]"; })(!window['safari'] || safari.pushNotification);
    // Internet Explorer 6-11
    var isIE = /*@cc_on!@*/false || !!document.documentMode;
    // Edge 20+
    var isEdge = !isIE && !!window.StyleMedia;
    // Chrome 1+
    var isChrome = !!window.chrome && !!window.chrome.webstore;
    // Blink engine detection
    var isBlink = (isChrome || isOpera) && !!window.CSS;
if( isChrome == true || isOpera == true )
    { Conditions for Chrome or Opera }

else 
    {
   Conditions for other
    };
