ember-autofocus-modifier

Your ember component has just been rendered. Have you ever wanted to focus an element in the DOM right after that? Like focusing this lonely input on your page? Or like focusing a full-screen modal's close button?

This package wraps a modifier to autofocus an element in the DOM. It works for inputs and for other elements.

As an alternative to installing this package, you might want to consider using this snippet.

Usage

By default, it will search for the first non-disabled input in the dom node that it has been attached to.

You can specify a custom selector to target other element as the first positional parameter.

If no child is found, then it will try to focus the element itself.

Examples

To set the autofocus to an ember component:

<MyComponent {{autofocus}} />

To set the autofocus to a native html element:

<input {{autofocus}} />

To set the autofocus to the first focusable input of an html container:

Here, #input-2 will be focused as input-1 is disabled:

<form {{autofocus}}>
  <input id="input-1" disabled="disabled" />
  <input id="input-2" />
  <button type="submit" />
</form>

To set the autofocus to something else than an input in a node's children:

Here, the autofocus will be applied to the button

<form {{autofocus "button"}}>
  <input />
  <input />
  <button type="submit" />
</form>

If the autofocus is applied multiple times, the latest element will be auto-focused:

Here, the autofocus will be applied to the button

<form>
  <input {{autofocus}} />
  <input {{autofocus}} />
  <button {{autofocus}} type="submit" />
</form>

Installation

yarn add -D ember-autofocus-modifier

or

npm install --save-dev ember-autofocus-modifier

Compatibility

• Ember.js v3.28 or above
• Ember CLI v3.28 or above
• Node.js v18 or above
• TypeScript v5.0 or above

TypeScript usage

The autofocus helper has proper Glint types, which allow you to get strict type checking in your templates when using TypeScript.

Unless you are using strict mode templates (via first class component templates), you need to import the addon's Glint template registry entries as described in the Using Addons documentation:

// e.g. types/glint.d.ts
import "@glint/environment-ember-loose";
import type AutofocusRegistry from "ember-autofocus-modifier/template-registry";

declare module "@glint/environment-ember-loose/registry" {
  export default interface Registry
    extends AutofocusRegistry /* other addon registries */ {
    // local entries
  }
}
