Vue實現全局的toast組件方式

Vue全局的toast組件

1.創建toast組件

<template>
    <div class="toast" v-if="show">
        {{ msg }}
    </div>
</template>

<style scoped>
    .toast{
        position: fixed;
        left: 50%;
        top: 50%;
        transform: translate(-50%,-50%);
        border-radius: 3px;
        max-width: 200px;
        padding: 10px;
        background: #333;
        color: #fff;
        font-size: 14px;
        opacity: .9;
        text-align: justify;
        word-break: break-all;
        word-wrap: break-word;
    }
</style>

2.創建toast.js文件

import toast from "@/components/toast"
export default (Vue) => {
    let toastComp = Vue.extend(toast);
    function showToast(msg , duration = 3e3){
        let toastDom = new toastComp({
            data(){
                return{
                    show:true,
                    msg
                }
            }
        }).$mount()
        document.body.appendChild(toastDom.$el);
        setTimeout(() => {
            toastDom.show = false
        }, duration)
    }
    Vue.prototype.$toast = showToast;
}

3.安裝並使用 

import toast from "@/plugins/toast";
Vue.use(toast);

// 組件裡面使用
this.$toast("message");

vue自定義toast組件

//toast.js

const  TOAST_CLASS = 'toast'
const  TOAST_OUT_CLASS = 'toast out'
let innerHtml=""
function  toast(msg,time=1000) {
    let body=document.querySelector('#app');
    if(body.querySelector('.toast')){
        body.removeChild(body.querySelector('.toast'))
    }
    let toastElem = document.createElement('div')
    toastElem.setAttribute('class',TOAST_CLASS)
    innerHtml = `<sapn>${msg}</sapn>`
    toastElem.innerHTML = innerHtml;
    body.appendChild(toastElem);
    setTimeout(function () {
        toastElem.setAttribute('class',TOAST_OUT_CLASS)
    },time)
    setTimeout(function () {
        let elm = body.querySelector('.toast');
        if(elm){
            body.removeChild(elm)
        }
    },time+1000)

}
export  default toast

//toast.less

@-webkit-keyframes toastIn {
  0%{
    opacity: 1;
  }
  50%{
    opacity: 1;
  }
  100%{
    opacity: 1;
  }
}
@-webkit-keyframes toastOut {
  0%{
    opacity:1;
  }
  50%{
    opacity:0.7;
  }
  100%{
    opacity:0;
  }
}
//animation: name duration timing-function delay iteration-count direction;
.toast{
  position: fixed;
  z-index:99;
  background-color: rgba(0,0,0,0.6);
  color:#fff;
  padding:15px 25px;
  border-radius:5px;
  top: 50%;
  left:50%;
  font-size:18px;
  transform: translate(-50% , -50%);
  animation-name: toastIn;
  animation-duration: 1s;
  animation-iteration-count: 1;
  animation-delay: 0s;
}

.toast.out {
  animation-name: toastOut;
  animation-duration: 1s;
  animation-iteration-count: 1;
  animation-delay: 0s;
  animation-fill-mode: forwards;
}

使用

全局註入（main.js），this._toast(‘XXXX’)調用

import toast from "./utils/toast";
window._toast = toast
