A common scenario is when you want to redirect to a specific route with query parameters, but your URL isn't looking quite right. For instance, you may end up with /user-reservations;justBooked=true instead of the cleaner /user-reservations?justBooked=true. This can lead to confusion, especially if you’re expecting the latter format. Let's break down the solution so you can achieve the desired URL structure in your Angular application. The Problem You’re trying to navigate to the route /user-reservations while passing along a query parameter justBooked. To achieve this, you might have experimented with code snippets like the following: [[See Video to Reveal this Text or Code Snippet]] or [[See Video to Reveal this Text or Code Snippet]] However, the result from both approaches produces the URL in the format /user-reservations;justBooked=true, which is not what you intend. So, what’s going on? The Core Issue The issue here arises from how you're attempting to pass the parameters to the Angular router. When you provide the parameters directly in the array as another object, Angular interprets that as a route parameter rather than a query parameter. This is why the semicolon (;) appears in your URL. The Solution To properly navigate and include query parameters, you should use Angular's queryParams option. Here’s how you can adjust your navigation statement: [[See Video to Reveal this Text or Code Snippet]] This way, Angular understands that justBooked is a query parameter and appends it to the URL correctly, resulting in /user-reservations?justBooked=true. Step-by-Step Breakdown Identify the Route: Determine which route you want to navigate to, in this case, /user-reservations. Set Up Query Parameters: Instead of placing parameters in the route array, use the queryParams option to define them. Implement the Navigation: Write the navigation code as shown below to successfully pass the query parameters: [[See Video to Reveal this Text or Code Snippet]] Test the Navigation: After implementing this change, run your application and test the navigation to ensure it reflects the correct URL format. Final Thoughts Understanding how Angular handles routing and parameters is crucial for building efficient applications. By navigating using the queryParams object, you can ensure that your URLs remain clean and functional. If you ever encounter issues like the one discussed, remember to check how you’re passing parameters to the router and adjust accordingly. Now you should have a clearer understanding of how to manage route navigation parameters in Angular 9 effectively! Happy coding!
