子组件的值绑定到同一vue组件的另一个实例的属性。

Question

我有一个自定义组件的问题。问题是这样的。

这个屏幕实际上是3次相同的Vue组件。

<div class="passwords__form">
            <InputField class="passwords__field" label="Mot de passe actuel" :password="true" v-model="currentPassword" />
            <InputField class="passwords__field" label="Nouveau mot de passe" :password="true" v-model="newPassword" />
            <InputField class="passwords__field" label="Répéter le nouveau mot de passe" :password="true" v-model="repeatedPassword" />
            <Button title="Changer le mot de passe" @click="updatePassword"/>
</div>

这是组件的代码

<template>
  <div
    class="field__container"
    :class="{ 'field__container--disabled': disabled }"
  >
    <label
      :for="this._uid"
      class="field__label"
      :class="{ 'field__label--disabled': disabled }"
      v-if="labelEnabled"
      >{{ label }}</label
    >
    <input
      :id="this._uid"
      class="field__input"
      :class="{
        'left-rounded': !labelEnabled && !password,
        'right-rounded': !buttonEnabled && !password
      }"
      :value="value"
      :placeholder="placeholder"
      @input="$emit('input', $event.target.value)"
      @keyup.enter="$emit('keyup-enter')"
      :disabled="disabled"
      :type="fieldType"
    />
    <input
      v-if="password && enableShowPassword"
      type="checkbox"
      v-model="showPassword"
      id="password-checkbox"
      class="field__password-checkbox"
    /><label
      v-if="password && enableShowPassword"
      for="password-checkbox"
      class="field__password-checkbox-label"
      :class="{
        'right-rounded': !buttonEnabled,
      }"
    ><span v-if="enableShowPassword && showPassword"><EyeSlash class="field__password-checkbox-icon"/></span><span v-if="!showPassword" ><Eye class="field__password-checkbox-icon field__password-checkbox-icon--eye " /></span></label>
    <a
      v-if="buttonEnabled"
      class="field__button"
      @click.stop="$emit('button-click')"
    >
      {{ button }}
    </a>
  </div>
</template>

<script lang="ts">

  &__password-checkbox-label {
    background-color: $color-grey-9;
    padding: 0.6rem 1rem;
    cursor: pointer;

    &:hover,
    &:active {
      background-color: $color-complementary-lighter;
    }
  }

  &__password-checkbox-icon {
    width: 1.5rem;

    &--eye {
      position: relative;
      top: 1px;
    }
  }
}
</style>

我认为问题来自于 v-model 属性的复选框。在我看来，v-model绑定到了复选框上的 showPassword 属性，而不是绑定到InputField的当前实例。

我不知道为什么它的行为是这样的，我的错误是什么，以及如何纠正它做正确的方式。有人有什么线索吗？

我想你应该使用一个独特的 身份证 输入类型="password"，就像你输入一般的输入一样。:id="this._uid" 因为在一个HTML页面上，所有的 id元素中声明的''必须是唯一的。
