【中文标题】带有 Tailwind css 的 Vue 过渡在淡出时不可见

【英文标题】：Vue transitions with Tailwind css not visible on fade out

【问题描述】：

我使用 Tailwind css 和 Vue.js 来创建模态。 由于 Tailwind 不支持 Vue 2，因此我必须添加过渡。 你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">

                  <div class="mt-2">
                    <p class="text-sm text-gray-500">

                  </div>

              </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>

当模态出现时过渡可见，但在消失时不可见。我不确定我做错了什么。

关于在关闭模式时如何进行转换有什么想法吗？

【参考方案1】：

这是由于第 6 行包含 v-show="show" 的标签没有围绕它的转换造成的。

如果您使用leave-active-class="duration-300" 将该标签包装在另一个转换中，它将延迟该标签的消失，直到您的内部转换完成。
