问题描述
我为响应式侧边栏编写了代码。菜单关闭按钮有效，但打开按钮无效。
作业时，我必须在 Stimulus 的帮助下写下所有这些

用 sidebar_controller.js 编写的 js 代码
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");
}
});
}
}
这是截图。 关闭按钮有效，但菜单打开按钮无效。 我哪里做错了？问题出在 sidebar_controller.js 或 application.html 中的代码中吗？
请帮帮我。
