尾随CSS在淡出时不可见的VUE过渡 [英] Vue transitions with Tailwind css not visible on fade out

问题描述

我使用Tailwind CSS和Vue.js创建模态。 由于Tailwind不支持Vue 2，我必须添加过渡。 您可以在这里看到想要的效果： https://tailwindui.com/components/application-ui/overlays/modals

代码如下：

<template>
  <div>
    <button @click="show = true">Click</button>

    <!-- This example requires Tailwind CSS v2.0+ -->
    <div v-show="show" class="fixed z-10 inset-0 overflow-y-auto" aria-labelledby="modal-title" role="dialog" aria-modal="true">
      <div class="flex items-end justify-center min-h-screen pt-4 px-4 pb-20 text-center sm:block sm:p-0">
        <!--
          Background overlay, show/hide based on modal state.

          Entering: "ease-out duration-300"
            From: "opacity-0"
            To: "opacity-100"
          Leaving: "ease-in duration-200"
            From: "opacity-100"
            To: "opacity-0"
        -->
        <transition name="ease-out-overlay">
          <div v-show="show" class="fixed inset-0 bg-gray-500 bg-opacity-75 transition-opacity"></div>
        </transition>

        <!-- This element is to trick the browser into centering the modal contents. -->
        <span class="hidden sm:inline-block sm:align-middle sm:h-screen" aria-hidden="true">&#8203;</span>

        <!--
          Modal panel, show/hide based on modal state.

          Entering: "ease-out duration-300"
            From: "opacity-0 translate-y-4 sm:translate-y-0 sm:scale-95"
            To: "opacity-100 translate-y-0 sm:scale-100"
          Leaving: "ease-in duration-200"
            From: "opacity-100 translate-y-0 sm:scale-100"
            To: "opacity-0 translate-y-4 sm:translate-y-0 sm:scale-95"
        -->
        <transition name="ease-out-modal">
          <div v-show="show" class="inline-block align-bottom bg-white rounded-lg text-left overflow-hidden shadow-xl transform transition-all sm:my-8 sm:align-middle sm:max-w-lg sm:w-full">
            <div class="bg-white px-4 pt-5 pb-4 sm:p-6 sm:pb-4">

                Cancel
              </button>
            </div>
          </div>
        </transition>
      </div>
    </div>

  </div>
</template>

<script lang="ts">
import { Component, Vue, Prop } from 'nuxt-property-decorator';

@Component
export default class TestModal extends Vue {
  @Prop({ type: Boolean, required: false })
  show: boolean = false;

  layout () {
    return 'none';
  }
}
</script>

<style scoped>

.ease-out-overlay-enter-active, .ease-out-overlay-leave-active {
  @apply opacity-100 duration-300;
}

.ease-out-overlay-enter, .ease-out-overlay-leave-to /* .fade-leave-active below version 2.1.8 */ {
  @apply ease-in opacity-0 duration-200;
}

.ease-out-modal-enter-active, .ease-out-modal-leave-active {
  @apply opacity-100 translate-y-0 sm:scale-100 duration-300;
}

.ease-out-modal-enter, .ease-out-modal-leave-to /* .fade-leave-active below version 2.1.8 */ {
  @apply ease-in opacity-0 translate-y-4 sm:translate-y-0 sm:scale-95 duration-200;
}

</style>

当模式出现时，过渡可见，但在模式消失时不可见。我不确定我做错了什么。

关于如何在关闭模式时进行过渡有什么想法吗？

推荐答案

这是由于第6行上包含v-show="show"的标记没有围绕它的过渡造成的。

如果使用leave-active-class="duration-300"将该标记包装在另一个转换中，它将延迟该标记消失，直到内部转换完成。
