<template>

</template>
<script>
export default {
  methods: {
    showConfirm() {
      this.$confirm({
        title: 'Do you want to delete these items?',
        content: 'When clicked the OK button, this dialog will be closed after 1 second',
        onOk() {
          return new Promise((resolve, reject) => {
            setTimeout(Math.random() > 0.5 ? resolve : reject, 1000);
          }).catch(() => console.log('Oops errors!'));
        },
        onCancel() {},
