<template>
  <div class="context" v-show="isshow">
    <span class="tip">{{ text }}</span>
  </div>
</template>

<script>
export default {
  name: "Toast",
  props: {
    isshow: {
      type: Boolean,
    },
    text: {
      type: String,
    },
  },
  watch: {
    isshow(val) {
      if (val === true) {
        setTimeout(() => {
          this.isshow = false;
        }, 3000);
      }
    },
  },
};

</script>
<style lang="less" scoped>
.context {
  position: absolute;
  top: 0;
  width: 100%;
  height: 100%;
  z-index: 100;
  display: flex;
  justify-content: center;
  align-items: center;
  .tip {
    background-color: rgba(40, 40, 40, 0.8);
    color: aliceblue;
    font-size: 0.6rem;
    padding: 0.2rem;
    border-radius: 0.1rem;
  }
}
</style>

import Toast from "./Toast.vue";
let NewToast = {
  install: function (Vue) {
    //创建vue插件，官方地址https://cn.vuejs.org/v2/guide/plugins.html
    let newToast = Vue.extend(Toast); //创建vue构造器,官方地址https://cn.vuejs.org/v2/api/#Vue-extend
    let toast = new newToast(); //创建实例
    document.body.appendChild(toast.$mount().$el); //挂载
    Vue.prototype.$Toast = function (text) {
      toast.isshow = true; // 传入props
      toast.text = text; // 传入props
    };
  },
};
export { NewToast };

import { NewToast } from "@/components/index.js";
Vue.use(NewToast);

but() {
    this.$Toast("Are you ok ?");
},

Toast.success('成功文案');
Toast.fail('失败文案');

this.$toast.success("成功文案");
this.$toast.fail("失败文案");
