功能介绍

打印功能支持 vue3.x 和 vue2.7.x

设计来源

首先感谢 react-to-print ,本项目的打印功能极大地参考了其实现方式，并结合Vue等相关特性进行了调整。

由于现有Vue生态的打印插件功能都不太理想，所以本插件应运而生， 并依赖 vue-demi实现对Vue2和Vue3的支持！

安装

npm install vue-create-print

Component方式使用

<script setup lang="ts">
import { VueCreatePrint } from 'vue-create-print'
import { ref } from 'vue'

const num = ref(0)
const radio = ref('a')
function handleAfterPrint() {
  console.log('after print')
}

function handleBeforePrint() {
  console.log('before print')
  num.value += 10
  return Promise.resolve()
}
function handlePrintError(errorLocation: 'onBeforePrint' | 'print', err: Error) {
  console.error('print error', err, errorLocation)
}
</script>

<template>
  <div>
    <VueCreatePrint
      :on-after-print="handleAfterPrint"
      :on-before-print="handleBeforePrint"
      :on-print-error="handlePrintError"
      :remove-after-print="true"
    >
      <template #default="{ handlePrint }">
