Binding functions with attributes

Question

Is there a way to bind functions with attributes, something like this:

<a _href="{{go('login')}}">Login</a>

then

String go(String routePath) {
  // Returns url for login
}

Answer 1

For routing task, you may bind using additional attribute for path:

<a route="/api/login" on-tap="{{go}}">

and then, in your go function:

void go(Event e, var detail, Element sender) {
  e.preventDefault();
  fire('change-route', detail: sender.attributes['route'] );
}
