如何从按钮单击加载组件？

Question

I'm creating a simple react app. I need to load a component from a button click. When I click the edit button I need to load the edit component. I tried it using <Link> . But I can't understand how to give the relative path. It means it need to load it like http://localhost:3002/viewTicket/603c9a02a2ccd501f45f820e/edit . I need to load it from http://localhost:3002/viewTicket/603c9a02a2ccd501f45f820e . How can I give the relative path?

App.js

<Provider store={configureStore()}>
      <BrowserRouter>
        <div className="App">
          <LayoutWrapper>
            <Switch>
              <Route path="/" exact component={Home} />
              <Route path="/viewTicket/:id" exact component={ViewTicket} />
              <Route path="/viewTicket/:id/edit" exact component={EditTicket} />
            </Switch>
          </LayoutWrapper>
        </div>
      </BrowserRouter>
    </Provider>

Ticket.js

                       <Link to="/viewTicket/:id/edit">
                          <Button size="lg" onClick={this.handleEdit}>
                            <Pencil />
                            &nbsp; Edit
                          </Button>
                        </Link>

But url lokks like this. Is there any other way to do this?

Answer 1

You forgot to include the actual ID in the URL. You're just directing the user to this literal string that has ":id" in it:

<Link to="/viewTicket/:id/edit">

Whatever your ID values is (for demonstration let's assume it's in a variable called id ), you'd use that to build your URL:

<Link to={`/viewTicket/${id}/edit`}>

As an aside, this is a very strange structure and will likely lead to confusion:

<Link to="/viewTicket/:id/edit">
  <Button size="lg" onClick={this.handleEdit}>

Putting a button inside of a link means that you're trying to simultaneously do two different things. Should this.handleEdit be invoked? Or should the user be redirected by the link? It's best to invoke a single operation. If some logic needs to happen inside of this.handleEdit before redirecting the user, then remove the <Link> and manually redirect the user (likely using the useHistory hook) after performing that logic.
