javascript - Skapa en responsiv sidopanel med Stimulus
Jag skrev koden för den responsiva sidomenyn. Menyknappen för att stänga fungerar, men knappen för att öppna fungerar inte.
På uppdrag måste jag skriva allt detta med hjälp av Stimulus

js-kod skriven i sidebar_controller.js
Import { Controller } from "stimulus";
export default class extends Controller {
static targets = ["element"];
toggle(event) {
event.preventDefault();
this.elementTargets.forEach((element) => {
if (element.classList.contains("hidden")) {
element.classList.remove("hidden");
element.classList.add("block");
} else {
element.classList.add("hidden");
element.classList.remove("block");
}
});
}
}
Här är skärmdumpar. Stängknappen fungerar, men knappen för att öppna menyn fungerar inte. Var gjorde jag fel? Är problemet i koden i sidebar_controller.js eller i application.html?
Hjälp mig, snälla.
Svar #1
Mitt svar till alla som stöter på samma problem är att på något sätt påverkar stimulus-use din kod; jag kommenterar data-transition-*, och det fungerar bra. Dessutom behöver du i kontrollern inte lägga till eller ta bort klassen block.
