localroute | Javascript library for public transport route planning | Map library

I wouldn't use the hideButton value as it'll always be true for every other page,

I'll check the current page by looking at the pathname on the route and if the route has details then isBookDetailsPage is true and if not then it's false

So technically your code should look like this

To retrieve a RouteData value, you can specify a token within the template for a route. For example, the route {version} would add a RouteData value of version that would be taken from the URL's first segment. In your example, you don't specify a token for version and so there will be no RouteData value for it, as you've described.

The solution for your specific problem is two-part:

1. Instead of using specific values when creating new SelectorModels, use a token as described above.
2. With this in place, you will now be able to access a version value from RouteData, but the new problem is that any value can be provided, whether or not it was specified in your configuration.

To solve the second problem, you can turn to IActionConstraint. Here's an implementation:

Let's assume you have these oversimplified structures:
