Parameters
id: string
Returns Link
Properties
element
The element the behavior was attached to.
listener
The callback function that triggers the route change.
Static bindings
This static property lets you define listeners that will be executed whenproperties of the behavior change.
It should be a map where the keys are paths that should be watched on the behavior instanceand the values are names of methods that will be invoked on it when the valueat a path changes.
Example
The following example shows a behavior that reacts to a change in the height ofthe defining element.
export default class MyBehavior extends Behavior { static inject: {element: Element}; static bindings = { 'element.clientHeight': 'heightChange' }; width: number; heightChange(height: number) { this.width = height * 2; }}Static update
This static property defines the name of an instance method thatwill be executed when the bahavior's value changes. Thatsimply means that the result of the expression that was createdfrom the value of the attribute used to define the behavior ina template has changed.
This will always create a one way binding.
Example
The following bahavior will execute its update method everytime the result of the expression given as an attribute valuechanges.
export default class MyBehavior extends Behavior { static update = 'update'; update() {}}Methods
remove
Removes the added event listener.
Returns void
The Link behavior can be used to navigate to a desiredroute by using its ID. A click event will be attached tothe element on which the behavior is defined.
Example
A simple example that creates a link to the route with theID about.
<button link="about">About</button>{ default } from mahalo/behaviors/link
