I am looking to display a div using either the ng-if or ng-show/hide directives if the user accesses the page through a specific browser, such as Chrome/Chromium. However, I am unsure of the optimal location to place this functionality.
The JavaScript code required for detecting the browser is as follows:
/chrome/i.test( navigator.userAgent )Take a look at the comprehensive browser detection script provided below
http://www.quirksmode.org/js/detect.html
I recommend utilizing either "Directive" or "Filter"
See an example of using the filter:
angular.module('myApp', []).filter('checkBrowser', function(){
return function(){
return /chrome/i.test(navigator.userAgent)
}
})
Template Code:
<div ng-show="{{''|checkBrowser}}">Hello</div>
To set up a condition in your Angular controller, you can create a scoped variable like this:
angular.module('myApp', []).controller('MyCtrl', ['$scope', function( $scope ) {
$scope.isChrome = /chrome/i.test(navigator.userAgent);
});
In your view, you can then use the variable like so:
<div data-ng-show="isChrome">You're using Chrome!</div>
If you require a variable that needs to be accessible across controllers, you can utilize a Service:
angular.module('myApp', []).factory('UAService', function() {
return {
isChrome: /chrome/i.test(navigator.userAgent)
};
});
You can inject and use this service in your controllers like this:
angular.module('myApp', []).controller('MyCtrl', ['$scope', 'UAService', function( $scope, UAService ) {
$scope.UAService = UAService;
});
Now, you can access the service from any scope within the scope created by your top-level controller:
<div data-ng-show="UAService.isChrome">You're running Chrome!</div>
