Browser refresh event in angular 6

Posted by: admin November 8, Leave a comment. I am new to angular. How can I detect userAgent in angular. Is it possible to use that in controller? Tried something like below but no luck! Detecting browser make and version is generally a bad smell. This generally means that you there is a bigger problem with the code if you need JavaScript to detect specific versions of browser. This should be solved by checking for WebSocket support, and applying a polyfill if there is no native support.

That being said, you can easily create service that would return the browser. There are valid cases where a feature exists in a browser but the implementation is outdated or broken.

Modernizr is not appropriate for these cases. Note: This is just an example of how to create a service in angular that will sniff the userAgent string. This is just a code example that is not expected to work in production and report all browsers in all situations. These libs place an object on the window named bowser or detect respectively.

You would then inject one of these the usual way, and use the API provided by the lib. If you choose to use another lib that instead uses a constructor method, you would create a factory that instantiates it:.

In this example we just need to test for IE 9, and we are going to use the bowser lib above. Now in a controller or service you can inject the browserAdapter and just do if browserAdapter. If later you wanted to use detect instead of bowser, the changes in your code would be isolated to the BrowserAdapter. In reality these values never change. IF you load the page in IE 9 it will never become Chrome So instead of registering the BrowserAdapter as a service, just put the result in a value or constant.

I want to detect when page is refresh using router in my single page application Angular project. An Angular application is a single page application, and in the context of a single page application the full app is loaded once, and data or screens are refreshed as the user uses your application. A browser refresh is the equivalent of shutting down your application and launching it again.

There is no default way to respond to this inside your Angular application. You might be able to mock something up using onBeforeUnload to log that the application was reloaded; and then check that log in your application's initialization routine to perform some special action. You add a top level resolver to the router. If you have a single top level router, then it will only be resolved once and children will handle page navigation.

Each time the resolver is resolved is equal to a page refresh in the browser. Learn more. Ask Question.

Responding to the Lavender Letter and commitments moving forward. RelatedThis morning, while digging into the "retain scroll" feature that was released with Angular 6, I discovered that the Angular team added a "navigationTrigger" property and a "restoredState" property to the NavigationStart Router event.

This is an exciting addition to the Router as it finally gives us the ability to differentiate between an imperative navigation ex, the user clicked a router-link and a location-change navigation ex, the user clicked the Back or Forward buttons in the browser chrome. This insight is something that I struggled with in Angular 5 when building my "restore scroll position" polyfill ; and, is something that will make custom behaviors like my polyfill much easier to implement.

Even navigation events that are considering "going back" or "going forward" within the Browser's history are given a unique ID. What's great about the Router updates in Angular 6 is that the NavigationStart event now also includes the unique ID of the navigation event being restored by a "popstate" event ie, a non-imperative navigation event. This restored state ID is provided in a property called, "restoredState".

And, we can use the existence of this property to determine if the navigation was triggered in attempt to move to a completely new browser state the "restoredState" will be null ; or, if the navigation was triggered in an attempt to move to an historical browser state. ASIDE : The NavigationStart event also includes a "navigationTrigger" property to provide a more technical indication of what triggered the navigation; at this time, however, I am not yet sure what additional value there is to knowing why the navigation occurred.

I am sure that there are use-cases for its consumption; but, for the time-being, knowing the restored state seems like the most valuable facet of this update. To explore this Router behavior, I created a simple demo in which you can navigate between three routes, each of which has three anchor links.

As you navigate through the app, the details of the NavigationStart event are logged to the console. And, if you go "back" and "forward" through your Browser's history, you will see how the IDs of previous navigation events are presented as the "restoredState" IDs:. As you can see, as we navigate through the application, each NavigationStart event is listed as an "imperative" navigation action that has no "restoredState" property.

This is really cool! Obviously, the Angular team added this functionality to enable their own "restore scroll" functionality. However, said functionality only works on the primary viewport as far as I understand. As such, I believe that I can use this functionality to greatly improve the stability of my own "restore scroll" polyfill, which works on an arbitrary collection of scrollable containers. I am not sure I understand what you are saying.

In my experience, when I use the Router to navigate, the History is kept in tact, unless I explicitly tell it to replace the replaceUrl property to overwrite the current history item:. By default, the Router seems to work naturally with the History object. Hi Ben, I have used same component for tabbed navigation.The save method in HeroDetailComponent navigates to the. As you can see, wow—this was not trivial.

The refresh of the page should trigger the event handler bound to a window:beforeunload. One such feature is View Refresh.
