<script>
export default {

  data () {
    return {
      text: 'defaultText',
      confirmZenVmodel: false,
      baseOption: {

      console.info('ConfirmZen open methods', opt)
      if (option.cancelBtnHandle) {

          this.$getAc()
            .use(option.cancelBtnHandle)
            .use(this.cancelBtnHandleInner)
            .run()
        }

      this.text = opt.text
      this.confirmZenVmodel = true

    <modalError ref="modalErrorRef"></modalError>
  </div>
</template>
<script>
import modalError from '@/components/modalError/modalError.vue'
import Vue from 'vue'
export default {
  name: 'App',
  components: {
    modalError,
  },
  mounted () {
    Vue.prototype.$modalError = this.$refs.modalErrorRef
  },
</script>

代码使用

    this.$modalError.open({
      text: JSON.parse(res.msg).join('<br><br>')
    })
