How To Install Hibernate Tools In Radius' title='How To Install Hibernate Tools In Radius' />Angular 2 Routing and Navigation Example. By Arvind Rai, April 0. This page will walk through angular 2 routing and navigation example. Using angular router we can navigate from one view to next while performing our task. Every component can be mapped with a URL and when that URL is accessed by browser or by a link on the page then the corresponding component is displayed. We can pass optional parameter with the URL that will be fetched in component to filter data to display. In our HTML template we can bind router to a link and when link is clicked, it will navigate to appropriate view. We can configure a URL to redirect to next URL. We can also handle 4. Not Found in angular routing. Angular routing provides location service using which we can go back and forward through the history of pages using a button. Here on this page first we will discuss the angular routing API and then we will create a book library for routing and navigation demo. In our example we will navigate from one view to next using menu item as well as button given on the page. Let us start now. Find the software used in our example.

Here we will provide API description and their usability in our routing application. Let us start one by one. Die Roten Rosen Wir Warten Aufs Christkind Rar. Router. Module and Routes Router. Module is a separate module in angular that provides required services and directives to use routing and navigation in angular application. Routes defines and array of roots that map a path to a component. Paths are configured in module to make available it globally. To use Router. Module and Routes in module, find the steps. Import Router. Module and Routes. First of all we will import Router. Module and Routes in our component. Router. Module, Routes from angularrouter 2. Create Array of Routes Create array of Routes in which we map a URL with a component. Routes. path manage book, component Manage. Book. Component. Update. Book. Component. To manage book, path. Match full. path, component Page. Not. Found. Component. Let us understand the path mapping. Mapping a Route to a Component Find the mapping. Manage. Book. Component. In the above mapping when we access URL manage book then Manage. Book. Component will be displayed. Configure Parameters Find the mapping. Update. Book. Component. In the above path mapping we need to pass a path parameter, for example if we access the URL update book1. Update. Book. Component will be displayed. Redirect to a URL Find the mapping. To manage book, path. Match full. If we access a URL without specifying any component path such as then it will be redirected to URL manage book path and hence by default Manage. Book. Component will be displayed. Handling Page Not Found Find the mapping. Page. Not. Found. Component. If we access path that has no mapping with any component, then to handle 4. Not Found error, we use a path that is mapped with any component to show desired message. Using Router. Module. Root Now we need to import Router. Module. for. Rootroutes using imports metadata of Ng. Module. Here argument routes is our constant that we have defined above as array of Routes to map path with component. Router. Module. for. Rootroutes 2. Router. It is used to navigate from one component to another component. To use Router in any component, follow the steps. Import Router Import Router as follows. Router from angularrouter 2. Router Instance Make Router service available in component using dependency injection with constructor. Router. 3. Using Router navigate Call navigate method of Router and pass path and parameter if any, to navigate from one component to another component. Find the code snippet. Here URL update book id will be the path to navigate. When the navigate method will be executed, the component mapped with URL update book id will be displayed. Activated. Route and Params Activated. Route is an angular service that contains route specific information such as route parameters, global query params etc. Params is an angular router API that contains the parameter value. To get the parameter value from Params we need to pass key. To use Activated. Route and Params in our component, find the steps. Import Activated. Route and Params Import Activated. Route and Params as given below. Activated. Route, Params from angularrouter 2. Activated. Route Instance Make Activated. Route available in component using dependency injection with constructor. Activated. Route, private book. Service Book. Service. In the above code Book. Service is our service which we will create in our example. Routing with Parameters Now suppose a URL update book1. To understand the fetching of parameter, find the mapping of component which we configure in module. Update. Book. Component. URL update book1. Update. Book. Component. The path parameter will be accessed by id as given in path mapping with component. We will fetch URL as following. Mapparams Params this. Service. get. Bookparamsid. We need to know following points. Map operator allows us to perform an action with the current value of the Observable and map it to new Observable. Import switch. Map in component as follows. Map switch. Map handles an Observable as well as a Promise to retrieve the value they emit. In paramsid, id is the keyword used in URL mapping with component. URL update book1. Book. Book is a class that will be created in our example. Location Location is a service that is used to interact with browser URL for example navigating back and forward. Location has methods such as go, forward and back etc. To use Location service, find the following points. Import Location Import Location in component. Location from angularcommon 2. Location Instance Make Location available in component using dependency injection with constructor. Location. 3. Navigate Back If we want to go back, then we will call back method as follows. Router. Link and Router. Link. Active Router. Link is a directive that is used to bind a route with clickable HTML element. Router. Link. Active is a directive that is used to add or remove CSS classes. When the HTML element with Router. Link binding is clicked then the CSS classes bound with Router. Link. Active will be active. These directives are used are follows. Linkmanage book router. Link. Activeactive link gt. Manage Booklt a lta router. Linkview detail, book. View Detaillt a. In the first link router. Link is bound with a route and router. Link. Active is bound with a CSS class. When this linked will be clicked then the associated CSS class will be activated. In the second link we are binding only router. Link with a parameter. Router. Outlet Router. Outlet is a directive that is used as ltrouter outlet. The role of ltrouter outlet is to mark where the router displays a view. Find the code snippet. Class menu lta router. Linkhome router. Link. Activeactive link gt. Homelt a. Linkadd book router. Link. Activeactive link gt. Add Booklt a. Linkmanage book router.
