MessageBox

A set of modal boxes simulating system message box, mainly for alerting information, confirm operations and prompting messages.

By design MessageBox provides simulations of browsers' alert, confirm and prompt. Use Modal instead if needed more complicated contents.

Alert

Displays an alert modal with the optional specified content and an OK (auto-focused) button. By default it can not be closed on backdrop click.

An alert example using callback:

<template>
  <btn @click="alert" type="primary">Click to open an alert modal</btn>
</template>
<script>
  export default {
    methods: {
      alert () {
        this.$alert({
          title: 'Title',
          content: 'This is an alert message.'
        }, (msg) => {
          // callback after modal dismissed
          this.$notify(`You selected ${msg}.`)
        })
      }
    }
  }
</script>
<!-- message-box-alert.vue -->

Confirm

Displays a modal dialog with an optional message and two buttons, OK (auto-focused) and Cancel.

A confirm example using Promise:

<template>
  <btn @click="confirm" type="primary">Click to open a confirm modal</btn>
</template>
<script>
  export default {
    methods: {
      confirm () {
        this.$confirm({
          title: 'Confirm',
          content: 'This item will be permanently deleted. Continue?'
        })
          .then(() => {
            this.$notify({
              type: 'success',
              content: 'Delete completed.'
            })
          })
          .catch(() => {
            this.$notify('Delete canceled.')
          })
      }
    }
  }
</script>
<!-- message-box-confirm.vue -->

Prompt

Displays a dialog with an optional message prompting the user to input some text.

<template>
  <btn @click="confirm" type="primary">Click to open a prompt modal</btn>
</template>
<script>
  export default {
    methods: {
      confirm () {
        this.$prompt({
          title: 'Welcome',
          content: 'Please input your email:',
          // A simple input validator
          // returns the err msg (not valid) or null (valid)
          validator (value) {
            return /\[email protected]\S+\.\S+/.test(value) ? null : 'Email address is not valid!'
          }
        })
          .then((value) => {
            this.$notify({
              type: 'success',
              content: `You email address is ${value}`
            })
          })
          .catch(() => {
            this.$notify('Input canceled.')
          })
      }
    }
  }
</script>
<!-- message-box-prompt.vue -->

Global methods

Following global methods for Vue.prototype will be added if uiv is installed:

  • $alert(options, callback(msg))
  • $confirm(options, callback(err, msg))
  • $prompt(options, callback(err, msg))

Callback params:

  • err as user dismiss or cancel the box, otherwise it will be null. Note that there is no err in $alert callback.
  • msg as the user input while using prompt.

Each of these methods will return a Promise object that resolve / reject while the box is closed (if supported by browser or with es6 promise polyfill).

Import individually

If you prefer importing MessageBox individually:

import { MessageBox } from 'uiv'

The corresponding methods are: MessageBox.alert, MessageBox.confirm and MessageBox.prompt, with same parameters as above.

Note: You CAN NOT use MessageBox individually like this if you're also using vue-i18n in the root instance of Vue (because it will not be able to access the correct language pack), a workaround is to register them manually:

import Vue from 'vue'
import { MessageBox } from 'uiv'

Vue.prototype.$alert = MessageBox.alert
// ...
