vue3，页面刷新完毕，routes没有插入进去， // 初始化恢复路由 const restoreRoutes = async () => { const data = await getAddRoutes(); // 获取动态路由表 console.log("恢复路由", data); if (!data) return; try { // 防止重复添加// 检查路由是否已存在 if (data.length > 0 && !router.hasRoute(data.name)) { // let resoult = await setRoutes(data); // 恢复路由当前路由 await data.forEach((item) => { router.addRoute(item); }); console.log("添加路由成功", currentMenu.value.path); // 恢复路由当前路由 router.push(getCurrentMenu().path); } } catch (e) { console.error("路由恢复失败:", e); removeAddRoutes(); } };

2. 在应用初始化时（如路由守卫或main.ts中）检查是否存在已保存的动态路由数据，并在路由实例创建后立即添加这些路由。 3. 使用router.hasRoute()方法检查路由是否已经存在，避免重复添加导致的问题。 4. 调整路由...

float浮动子元素后导致父元素无高度(0)解决方法

前言 float 属性定义元素在哪个方向浮动。以往这个属性总应用于图像，使文本围绕在图像周围，不过在 CSS 中，任何元素都可以浮动。浮动元素会生成一个块级框，而不论它本身是何种元素。如果浮动非替换元素，则要指定一个明确的宽度；否则，它们会尽可能地窄。假如在一行之上只有极少的空间可供浮动元素，那么这个元素会跳至下一行，这个过程会持续到某一行拥有足够的空间为止。使用float左浮动后，元素便脱离了...
