vue.js中toast用法及使用toast弹框的实例代码

import { Toast } from 'vant'

showToast() {
    this.$toast({
     message: "今日签到+3",
     })
  },

import { ToastPlugin,ConfirmPlugin,AlertPlugin} from 'vux'
Vue.use(ToastPlugin)
Vue.use(ConfirmPlugin)
Vue.use(AlertPlugin)
//公用的弹窗(全局变量)
Vue.prototype.showToast = function( showPositionValue,type,text,width="10em"){
 this.$vux.toast.show({
 showPositionValue: false,
 text: text,
 type: type,
 width: width,
 position: 'middle'
 })
}
//公用alert confirm
const Message = {};
Message.install = () => {
 const msg = {
   alert: config => {
   let def = {
    title:'提示',
    content:'系统异常，请重新登录后再试！',
    buttonText:'确定'
   }
   if(typeof config === 'string' || typeof config === 'number'){
  Vue.$vux.alert.show(Object.assign(def,{content:config}));
 }else{
  Vue.$vux.alert.show(Object.assign(def,config));
 }
},
 confirm: config => {
  let isConfirm = false;
  let def = {
    title:'提示',
    content:'系统异常，请重新登录后再试！',
    confirmText:'确定',
    cancelText:'取消',
    onConfirm:() =>{
    isConfirm = true;
 }
 }
  if(typeof config === 'string' || typeof config === 'number'){
   Vue.$vux.confirm.show(Object.assign(def,{content:config}));
  }else{
   Vue.$vux.confirm.show(Object.assign(def,config));
  }
 /return new Promise((resolve,reject) => {
  if(isConfirm){
  resolve();
  }
  })/
 },
}
 Object.entries(msg).forEach(([method,fn]) => {
  Vue.prototype[method] = fn;
})
}
Vue.use(Message)
//使用例子
_this.confirm({
 title:'提示',
 content: '确定要关闭订单',
 onConfirm() {
  console.log('取消订单了')；
 }
});
