vue全局彈窗

vue已經成爲前端一個必備技能了，就像當年的jquery，因此好好學吧~

很少說上代碼

// index.vue 彈框主體，能夠直接組件的形式引用，後面會介紹如何在使用 this.$xxxx
<template>
  <div v-if="!destroyDom" class="panel">
    <transition name="fade">
      <div v-if="visible" :style="{opacity:data.mask?1:0}" class="panel_mask" @click="action({type:'mask'})" />
    </transition>
    <transition name="bounce" @after-leave="destroyDomHandle">
      <div v-if="visible" class="panel-wrap" :class="data.class">
        <div v-if="data.title" class="panel-title" v-html="data.title" />
        <div v-if="!component" class="panel-content" v-html="data.content" />
        <div v-if="component" class="panel-content">
          <component :is="_component" ref="component" />
        </div>
        <div class="panel-btn">
          <div v-for="(btn,index) in btns" :key="index" :class="`panel-${btn.type}`" @click="action(btn)">{{ btn.text }}</div>
        </div>
      </div>
    </transition>
  </div>
</template>

<script> export default { name: 'Panel', props: { component: { type: Function, default: null }, data: { type: Object, required: true }, btns: { type: Array, default: () => { return [ { text: '知道了', type: 'cancel' } ] } }, listener: { // 每一個階段會回調 type: Function, default: null } }, data() { return { visible: false, destroyDom: false } }, computed: { _component() { // 能夠傳入vnode 同時也保留了傳html const fn = this.component let vNode return { name: 'panel-component', render() { vNode = fn() return vNode } } } }, created() { this.listener && this.listener({ acr: 'start' }) this.data.delay && setTimeout(() => { this.close() }, this.data.delay) }, methods: { destroyDomHandle() { // 動畫結束後把這塊這塊銷燬 this.destroyDom = true this.listener && this.listener({ act: 'destroy' }) }, close() { this.visible = false this.listener && this.listener({ act: 'close' }) }, action(btn) { this.listener && this.listener({ act: 'click', type: btn.type }) if (btn && btn.callback) { btn.callback(this.close) } else { this.close() } } } } </script>
// 下面就是一些樣式，適用移動端，並使用rem作的適配
<style scoped lang="less"> @designwidth: 750; .bounce-enter-active { animation: bounce-in 0.4s; } .bounce-leave-active { animation: bounce-in 0.4s reverse; } @keyframes bounce-in { 0% { transform: translate3d(-50%, -32%, 0) scale(0); opacity: 0; } 50% { transform: translate3d(-50%, -31%, 0) scale(1.1); opacity: 0.8; } 100% { transform: translate3d(-50%, -30%, 0) scale(1); opacity: 1; } } .fade-enter-active, .fade-leave-active { transition: all 0.4s; } .fade-enter, .fade-leave-to { opacity: 0; } .panel_mask { position: fixed; z-index: 99; top: 0; left: 0; right: 0; bottom: 0; background: rgba(0, 0, 0, 0.3); } .panel-wrap { position: fixed; top: 30%; left: 50%; z-index: 100; transform: translate3d(-50%, -30%, 0); width: 70%; // max-height: 70%; background: #f8f8f8; border-radius: rem(16); box-sizing: border-box; } .panel-title { padding: rem(10) 0; width: 100%; text-align: center; // max-height: 1rem; font-size: rem(36); overflow: hidden; box-sizing: border-box; color: #666; text-overflow: ellipsis; border-bottom: 1px solid #d9d9d9; white-space: nowrap; } .panel-content { padding: rem(20) rem(20); width: 100%; max-height: 60vh; overflow-y: auto; font-size: rem(30); box-sizing: border-box; text-align: center; } .panel-btn { text-align: center; display: flex; width: 100%; border-top: 1px solid #d9d9d9; color: #4e82d7; } .panel-btn > div { flex: 1; padding: rem(10) 0; border-left: 1px solid #d9d9d9; border-radius: 0.12rem; font-size: rem(30); &:nth-child(1) { border-left: 0; } } </style>

渲染到頁面

// render.js

import Tpl from './index.vue'

export default function create(Vue, { store = {}, router = {}}, options) {
  const comp = new Vue({
    name: 'Root' + Tpl.name,
    router,
    store,
    data() {
      return {
        options: { ...options }
      }
    },
    render(h) {
      return h(Tpl, {
        props: this.options
      })
    }
  })

  comp.$mount()
  document.body.appendChild(comp.$el)
  comp.$children[0].visible = true


  return {
    close: () => comp.$children[0].close() // 暴露出去一個關閉的方法
  }
}

掛載

// index.js
import create from './render'

export default {
  install(Vue, options = {}) {
    Vue.prototype.$panel = create.bind(this, Vue, options)
  }
}
複製代碼

使用

// main.js
import Vue from 'vue'
import App from './App.vue'
import Panel from './base/panel'

Vue.use(Panel)

new Vue({
  render: h => h(App)
}).$mount('#app')

// 組件中全局使用
this.$panel({
    data: {
      class: 'xxxx',
      mask: true,
      title: '提示',
      content: 'xxx'
    },
    btns: [
      {
        text: '知道了',
        type: 'cancel',
        callback: () => { }
      }
    ],
    component: () => <div />,
    listener: (res) => {console.log(res)}
  })

經過控制參數能夠實現toast，能夠進行二次封裝
