In my project, there is a need to display an outdated browser message when a user has an older browser version.
Currently, I am using angular 1.5.5 and attempted to use the angular-bowser module. However, I encountered issues with old versions like IE8 since they do not support my Angular version, rendering the angular-bowser module ineffective.
Is there another solution, library, or method that anyone can suggest to address this issue?
When it comes to working with AngularJS, you have the flexibility to tap into native JavaScript for tasks like browser version detection:
JAVASCRIPT:
navigator.sayswho= (function(){
var ua= navigator.userAgent, tem,
M= ua.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\s*(\d+)/i) || [];
if(/trident/i.test(M[1])){
tem= /\brv[ :]+(\d+)/g.exec(ua) || [];
return 'IE '+(tem[1] || '');
}
if(M[1]=== 'Chrome'){
tem= ua.match(/\b(OPR|Edge)\/(\d+)/);
if(tem!= null) return tem.slice(1).join(' ').replace('OPR', 'Opera');
}
M= M[2]? [M[1], M[2]]: [navigator.appName, navigator.appVersion, '-?'];
if((tem= ua.match(/version\/(\d+)/i))!= null) M.splice(1, 1, tem[1]);
return M.join(' ');
})();
//Invoke
navigator.sayswho;
This function can be utilized in your Angular app to identify the current browser and its version, allowing you to customize your message dialog accordingly. For example:
JAVASCRIPT:
var version = navigator.sayswho;
if (version <= 8) {
alert("Browser outdated! Please update browser!");
return false; //don't forget.
}
const checkIfMobile = /Android|iPhone/i.test(window.navigator.userAgent)
If you're in need of browser detection, I recommend taking a look at Bowser. More information can be found here
You have the ability to utilize this
$scope.isOpera = !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0;
// Checking for Opera 8.0+ (UA detection to detect Blink/v8-powered Opera)
$scope.isFirefox = typeof InstallTrigger !== 'undefined'; // Identifying Firefox 1.0+
$scope.isSafari = Object.prototype.toString.call(window.HTMLElement).indexOf('Constructor') > 0;
// Confirming at least Safari 3+: "[object HTMLElementConstructor]"
$scope.isChrome = !!window.chrome && !$scope.isOpera; // Noting Chrome 1+
$scope.isIE = /*@cc_on!@*/ false || !!document.documentMode; // Verifying at least IE6
function getDevice() {
var userAgent = navigator.userAgent || navigator.vendor || window.opera;
if (userAgent.match(/iPhone/i) || userAgent.match(/Android/i)) {
// You have the option to insert code here for mobile devices
}
}
function hasGetUserMedia() {
return !!(navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia || navigator.msGetUserMedia);
}
if (!hasGetUserMedia()) {
alert('Your browser is not supported. Please switch to Google Chrome or Mozilla Firefox.');
}
Only the current browser's value will be true
