This diagnostic detects uninvoked functions in event bindings.
import {Component, signal, Signal} from '@angular/core';@Component({ template: `<button (click)="onClick">Click me</button>`,})class MyComponent { onClick() { console.log('clicked'); }}
What's wrong with that?
Functions in event bindings should be invoked when the event is triggered. If the function is not invoked, it will not execute when the event is triggered.
What should I do instead?
Ensure to invoke the function when you use it in an event binding to execute the function when the event is triggered.
import {Component} from '@angular/core';@Component({ template: `<button (click)="onClick()">Click me</button>`,})class MyComponent { onClick() { console.log('clicked'); }}
