Within the employee-list component, there is a table displaying a list of employees. This table includes an option to edit details.
<button type="button" class="btn btn-primary" routerLink="../create-employee">Edit</button>
When the edit button is clicked, I aim to display the create employee form (a different component) with an update button. Additionally, I would like for the existing data of the selected employee to be loaded into that form. How can I achieve this?
For handling different functionalities like "Edit" and "Create", it's essential to have separate components for each, as they are not exactly the same.
Hence, it is advisable to establish an EditEmployeeComponent specifically for editing employee details.
To navigate appropriately, employ the click event of a button to trigger a function that facilitates redirection. The redirection process can be executed like this:
this.router.navigate(["update-employee", selectedEmployeeID]);
Ensure to define the router variable within your constructor.
import {Router} from "@angular/router";
constructor (private router: Router) {}
This action will lead you to a path resembling /update-employee/1341341, embedding the record ID in the URL for subsequent extraction by the following EditEmployeeComponent.
In your current routing file, e.g., app.routing.module.ts, introduce a new route mapping to direct the "update-employee" URL towards your designated component (EditEmployeeComponent). The specific code structure can vary depending on the module arrangement.
{
path: "update-employee/:id",
loadChildren: ... // specify your new component here
},
In your newly created component, extract the query parameter from the URL to retrieve the corresponding employee details effectively.
ngOnInit() {
this.routeListener = this.route.params.subscribe(async (params) => {
const employeeId = params["id"];
this.employee = await this.employeeService.getEmployee(employeeID);
});
}
Remember to declare the route variable in your constructor.
constructor(
private employeeService: EmployeeService,
private route: ActivatedRoute,
) {}
For fetching employee details, consider utilizing an EmployeeService for streamlined access.
Note: Presumably, you already possess an EmployeeService given the existence of a create-employee form relying on similar APIs, consolidating related functionality within the service.
To display extracted employee data within a form and facilitate updates, integrate the information accordingly. Consider reusing components or logic from existing modules, such as CreateEmployeeComponent. Further insights on Angular forms can be found here.
