源代碼：

<template>
  <view v-if="show" class="lang-modal">
    <view class="lang-modal-mask" @click="handleClose"/>
    <view class="lang-modal-content">
      <view class="lang-title">??? ??????</view>
      <view 
        class="lang-item" 
        :class="{'active': locale === 'ug'}"
        @click="handleSelect('ug')"
      >
        <text>????????</text>
        <text v-if="locale === 'ug'" class="check-icon">?</text>
      </view>
      <view 
        class="lang-item" 
        :class="{'active': locale === 'zh'}"
        @click="handleSelect('zh')"
      >
        <text>簡體中文</text>
        <text v-if="locale === 'zh'" class="check-icon">?</text>
      </view>
    </view>
  </view>
</template>

<script lang="ts">

@keyframes fadeIn {

}

@keyframes slideIn {

    opacity: 0;
  }
  to {
    transform: translate(-50%, -50%);
    opacity: 1;

}
</style>

使用方式：

<nur-lang-modal :show.sync="showLanSelectModal"/>
