vue手写提示组件弹窗

1、弹框展示

2、message组件

新建一个message.vue

<template>
  <div class="wrapper" v-if="isShow" :class="showContent ? 'fadein' : 'fadeout'">{{ text }}</div>
</template>
<script>

</script>
<style scoped>
.wrapper {
  width: 200px;
  text-align: center;
  position: fixed;
  left: 50%;
  top: 50px;
  background: rgb(237, 242, 252);
  padding: 10px;
  border-radius: 5px;
  border: 1px solid rgb(235, 238, 245);
  transform: translate(-50%, -50%);
  color: rgb(201, 173, 153);
  font-size: 28px !important;
}

.fadein {
  animation: animate_in 1s;
}

.fadeout {
  animation: animate_out 1s;
  opacity: 0;
}

@keyframes animate_in {
  0% {
    opacity: 0;
  }

  100% {
    opacity: 1;
  }
}

@keyframes animate_out {
  0% {
    opacity: 1;
  }

  100% {
    opacity: 0;
  }
}
</style>

index.js 跟message组件放在同一目录下

import vue from 'vue'
//引入组件
import messComponent from './message.vue'
//创建构造器
const MessConstructor = vue.extend(messComponent)
function showMessage(text) {
  const message = new MessConstructor({
    el: document.createElement('div'),
    data() {
      return {
        text: text,
        isShow: true,    // 是否显示组件
        showContent: true  // 作用:在隐藏组件之前,显示隐藏动画
      }
    }
  })
  document.body.appendChild(message.$el)


  setTimeout(() => { message.showContent = false }, 2000)
  // 过了 duration 时间隐藏组件
  setTimeout(() => { message.isShow = false }, 2000 * 2)
}


function messageCom() {
//挂到vue上去，方便调用
  vue.prototype.$message = showMessage
}
export default messageCom
