How to use sweetalert2 pop-up plug-in in vue project

This article mainly introduces how to use the sweetalert2 pop-up plug-in in the vue project. It has certain reference value. Now I share it with you. Friends in need can refer to it

1). Install sweetalert2

npm install sweetalert2@7.15.1 --save

2). Encapsulate sweetalert2

in src Create a new plugins folder, and then create a new vue-sweetalert2.js file, copy and paste the following code:

src/plugins/vue-sweetalert2.js

import swal from 'sweetalert2'
export default {
  install: (Vue) => {
    // sweetalert2 的设置默认配置的方法
    swal.setDefaults({
      type: 'warning',
      showCancelButton: true,
      confirmButtonColor: 'rgb(140,212,245)',
      cancelButtonColor: 'rgb(193,193,193)'
    })
    // 添加全局方法
    Vue.swal = swal
    // 添加实例方法
    Vue.prototype.$swal = swal
  }
}

Here we encapsulate sweetalert2 into a plug-in, a plug-in for Vue.js There is a public method install. The first parameter of this method is the Vue constructor. After adding swal as a global method and instance method, we can access it through Vue.swal and this.$swal

3). Introduce and use the plug-in

Open the src/main.js file, introduce and use ./plugins/vue-sweetalert2 (single-line comment part is the modification involved):

src/main.js

import Vue from 'vue'
import App from './App'
import router from './router'
import './directives'
import './components'
import store from './store'
// 引入插件
import VueSweetalert2 from './plugins/vue-sweetalert2'
// 使用插件
Vue.use(VueSweetalert2)
Vue.config.productionTip = false
/* eslint-disable no-new */
new Vue({
  el: '#app',
  router,
  store,
  components: { App },
  template: &#39;<App/>&#39;
})

4). Add exit confirmation

Open src /components/layouts/TheEntry.vue file, modify logout method:

src/components/layouts/TheEntry.vue

logout() {
  this.$swal({
    text: '你确定要退出吗?',
    confirmButtonText: '退出'
  }).then((res) => {
    if (res.value) {
      this.$store.dispatch('logout')
    }
  })
}
