Component outputs

Receive every typed component output

Use declarative output handlers in .wrn files or register a direct output handler from JavaScript. The canonical API exposes payload and does not require event.detail.

@inputFires as the editable value changes.

@changeFires when the component's committed value or selection changes.

@focusFires when the interactive control receives focus.

@blurFires when focus leaves the interactive control.

@selectFires when an item, option, card, or result is selected.

@clearFires after the current value or selection is cleared.

@invalidFires when the component emits the invalid event.

Declarative handlers.wrn

<FileInput
  @input='console.log(payload)'
  @change='console.log(payload)'
  @focus='console.log(payload)'
  @blur='console.log(payload)'
  @select='console.log(payload)'
  @clear='console.log(payload)'
  @invalid='console.log(payload)'
/>

Direct output handlers.js

import { registerOutputHandler } from "@wrnexus/csr/outputs"

const component = document.querySelector("[data-ui-component=\"FileInput\"], [data-component=\"FileInput\"]")

if (component) registerOutputHandler(component, "input", (payload) => {
  console.log("input", payload)
})

if (component) registerOutputHandler(component, "change", (payload) => {
  console.log("change", payload)
})

if (component) registerOutputHandler(component, "focus", (payload) => {
  console.log("focus", payload)
})

if (component) registerOutputHandler(component, "blur", (payload) => {
  console.log("blur", payload)
})

if (component) registerOutputHandler(component, "select", (payload) => {
  console.log("select", payload)
})

if (component) registerOutputHandler(component, "clear", (payload) => {
  console.log("clear", payload)
})

if (component) registerOutputHandler(component, "invalid", (payload) => {
  console.log("invalid", payload)
