Vue.js 威利达特酒店；顺风：为什么我总是看到无效的错误？

就我的一生而言，我似乎无法理解为什么我总是看到验证错误。逻辑工作得很好，似乎在我的

：类
绑定中，我把它都搞错了。我知道当我弄明白这一点的时候，我会觉得自己很傻，但是在无数的教程之后，我觉得我真的是从中复制/粘贴了，我仍然在同一条船上

这是我的电子邮件模板。密码输入是相同的

<div class="relative">
    <label for="email" class="sr-only block text-sm font-medium leading-5 text-gray-700">
        Email address
    </label>
    <input type="email"
        id="email"
        v-model.trim="$v.user.email.$model"
        :class="{ 'border-red-500': !$v.user.email.required}"
        placeholder="Email"
        class="mt-1 placeholder-gray-400 shadow appearance-none border rounded w-full py-3 px-3 text-gray-700 leading-tight transition duration-150 ease-in-out sm:text-sm sm:leading-5 focus:outline-none focus:border-gray-400 focus:shadow-outline-gray"
    />
    <div class="absolute inset-y-0 right-0 pr-3 flex items-center pointer-events-none" 
        v-if="!$v.user.email.required">
              <svg
                  class="h-5 w-5 text-red-500"
                  fill="currentColor"
                  viewBox="0 0 20 20"
              >
                <path
                    fill-rule="evenodd"
                    d="M18 10a8 8 0 11-16 0 8 8 0 0116 0zm-7 4a1 1 0 11-2 0 1 1 0 012 0zm-1-9a1 1 0 00-1 1v4a1 1 0 102 0V6a1 1 0 00-1-1z"
                    clip-rule="evenodd"
                />
              </svg>
            </div>
        </div>
    <div>
    <p class="mt-2 text-sm text-red-600" v-if="!$v.user.email.required">
        Email is required
    </p>
    <p class="mt-2 text-sm text-red-600" v-if="!$v.user.email.email">
        Please use a valid email address
    </p>
</div>

当我输入有效的电子邮件和/或密码时，验证错误就会消失。如果我试图提交无效数据，验证程序工作正常。使用有效的电子邮件/密码，我能够成功提交表单

当页面第一次加载时，我的表单是这样的。如果字段无效，如何正确地呈现表单以仅显示错误

谢谢你的建议

尝试将
$v.user.email.$error
条件添加到border类绑定、图标和错误消息中：

<div id="app">
  <div class="relative">
    <label for="email" class="sr-only block text-sm font-medium leading-5 text-gray-700">
      Email address
    </label>
    <input type="email" id="email" v-model.trim="$v.user.email.$model" :class="{ 'border-red-500': $v.user.email.$error}" placeholder="Email" class="mt-1 placeholder-gray-400 shadow appearance-none border rounded w-full py-3 px-3 text-gray-700 leading-tight transition duration-150 ease-in-out sm:text-sm sm:leading-5 focus:outline-none focus:border-gray-400 focus:shadow-outline-gray" />
    <div class="absolute inset-y-0 right-0 pr-3 flex items-center pointer-events-none" v-if="!$v.user.email.required">
      <svg v-if="$v.user.email.$error" class="h-5 w-5 text-red-500" fill="currentColor" viewBox="0 0 20 20">

这是在输入之前发生的吗？是的，上面的图片是页面加载时发生的情况-没有用户交互。如果我开始输入，验证将按预期进行并清除。
