页面展示
方案一
方案二
代码解释
方案一：使用v-show
这种方案只适合有两种页面
现在form表单中设置好要展现的页面名（此处的url没有作用不用管）
通过一个两个for循环分别将form表单填入的数据回显到页面中，并通过menuHandle函数进行 点击后会发生的事件，:index和:key都是用来定位那一个单独的div
可以看到点击后触发函数里这个show变量的true和flase。
而具体内容中写了两个页面内容，再通过v-if函数展现dish和comment页面
方案二：使用<iframe>
同样的通过两个v-for循环将menuList中的内容页面展现出来，同时绑定一个menuHandle函数，点击的时候触发该函数
该函数被触发的时候，就会将当前元素的id、url等元素填入到展现的form表单中
内容展现区就是通过<iframe>框架进行展现
