手把手教你使用Vue实现弹窗效果

<template>
  <div v-if="visible" class="popup">
    <!-- 弹窗的内容 -->
    <div class="popup-content">
      {{ content }}
    </div>
    <!-- 关闭按钮 -->
    <button class="close-button" @click="closePopup">关闭</button>
  </div>
</template>

<script>
export default {
  props: {
    visible: {
      type: Boolean,
      default: false
    },
    content: {
      type: String,
      default: ''
    }
  },
  methods: {
    closePopup() {
      this.$emit('close');
    }
  }
}
</script>

<style scoped>
.popup {
  position: fixed;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background: rgba(0, 0, 0, 0.5);
  display: flex;
  justify-content: center;
  align-items: center;
}

.popup-content {
  background: #fff;
  padding: 20px;
  border-radius: 5px;
}

.close-button {
  margin-top: 10px;
}
</style>

<template>
  <div>
    <button @click="showPopup">显示弹窗</button>
    <Popup :visible="popupVisible" :content="popupContent" @close="closePopup" />
  </div>
</template>

<script>
import Popup from './Popup.vue';

export default {
  components: {
    Popup
  },
  data() {
    return {
      popupVisible: false,
      popupContent: '这是一个弹窗'
    }
  },
  methods: {
    showPopup() {
      this.popupVisible = true;
    },
    closePopup() {
      this.popupVisible = false;
    }
  }
}
</script>

<template>
 <div>
 <div :class='{"itemCount":true,"leftT":!leftShow,"left":leftShow}'>//这种写法是动态获取样式
 <div style="font-size:60px;">表格数据</div>
 <div>//下面就是弹框内的样式。按自己需要放样式（我这里拿表格举例吧）
  <el-table :data="tableData"
   style="width: 100%">
  <el-table-column prop="date"
    label="日期"
    width="150">
  </el-table-column>
  <el-table-column label="配送信息">
  <el-table-column prop="name"
    label="姓名"
    width="120">
  </el-table-column>
  <el-table-column label="地址">
  <el-table-column prop="province"
     label="省份"
     width="120">
  </el-table-column>
  <el-table-column prop="city"
     label="市区"
     width="120">
  </el-table-column>
  <el-table-column prop="address"
     label="地址"
     width="300">

  <el-table-column prop="zip"
     label="邮编"
     width="120">
  </el-table-column>
  </el-table-column>
  </el-table-column>
  </el-table>
 </div>
 </div>
 </div>
</template>
export default {
 data(){
 leftShow:false
}
}
<script>
</script>

<style lang='less' scoped> //下面是设置的样式。就可以实现了。
 .itemCount { 
 position: absolute;
 top: 30%;
 background: yellowgreen;
 height:600px;
 padding: 10px;
 width:1000px;
 z-index: 2
 }
 .left { 
 left:0; 
 transition: left 0.5s;
 }
 .leftT {
 left:-1200px;
 transition: left 0.5s;
