我正在嘗試通過或多或少默認安裝 Symfony6 和 Encore 來學習 Stimulus，與默認安裝的主要區別之一是我使用的是 Typescript。Stimulus 檔案說應該像這樣使用型別值= >
export default class extends Controller {
static values = { index: Number }
initialize() {
console.log(this.indexValue)
console.log(typeof this.indexValue)
}
// …
}
但是，當使用 Typescript 時，我得到一個 TS2339: Property 'indexValue' does not exist on type 'default'.on access this.indexValue；我設法擺脫了這個，@ts-ignore但我認為這很糟糕。你知道在 webpack Encore Symfony 專案中有什么更簡潔的方法來處理這個問題嗎？提前謝謝??
我的刺激控制器 =>
import { Controller } from '@hotwired/stimulus';
default class extends Controller {
static values = {
index: Number
}
doSomethingAsync(event: Event) {
event.preventDefault();
// @ts-ignore
console.log("indexValue", this.indexValue);
}
}
我的 tsconfig =>

"target": "es6",
"jsx": "react",
"allowJs": true,
"moduleResolution": "node"

"exclude": [

}
我的webpack.config.js=>
const Encore = require('@symfony/webpack-encore');
// Manually configure the runtime environment if not already configured yet by the "encore" command.
// It's useful when you use tools that rely on webpack.config.js file.
if (!Encore.isRuntimeEnvironmentConfigured()) {
Encore.configureRuntimeEnvironment(process.env.NODE_ENV || 'dev');
}
Encore
// directory where compiled assets will be stored
.setOutputPath('public/build/')

.setPublicPath('/build')

.enableStimulusBridge('./assets/controllers.json')

.splitEntryChunks()

uj5u.com熱心網友回復：
Stimulus 中的 Typescript 支持仍然有一些粗糙的邊緣，但是這里有一個許多用戶發現適合他們的解決方案。
首先設定一個包含通用型別和忽略注釋的抽象類。
import { Controller } from '@hotwired/stimulus';
export default abstract class AbstractController<StimulusElement extends Element> extends Controller {
// @ts-ignore see https://discuss.hotwired.dev/t/stimulus-and-typescript/2458
declare readonly element: StimulusElement;
}
然后在你的控制器中，擴展抽象的，有些事情會更容易，你仍然需要宣告單獨使用indexValue.
import AbstractController from '../src/AbstractController';
export default class extends AbstractController<HTMLButtonElement> {
static values = {
index: Number,
};
static targets = [
'name'
];
declare readonly indexValue: number
declare readonly nameTarget: HTMLInputElement
}
