如何用Vue实现Word文档自动分页与双页排版功能？

Question

用vue实现word的自动分页功能 双页排版 即用户输入的内容超过了一张A4纸的高度 则自动分页 将内容自动分割成两页 按照 左 右 左 右的方式排版 问题的难点在于 word的内容是不固定的 标题 table 图片 等等都有可能 而且要加入交互逻辑 比如弹出时间选择器 弹出输入框等等 目前外观是出来了 直接v-for渲染page页 但是接下来具体怎么做不知道 大家有什么思路吗？

Answer 1

自己实现估计是难度比较大的，可以参考这个 canvas-editor

集成示例: https://blog.csdn.net/weixin_52443895/article/details/139693928

Answer 2

kindEditor，自定义方法：（但是不能像word分页，因为是富文本。）

效果：（点击打印，调打印功能，选择纸张后，自动分页）

Answer 3

你好，此业务需求本人真实写过；前端实现起来很费劲的；解决办法是后端进行数据编排；每列的长度固定后计算出列数，若是长度超出A4字的宽度则绘制到新的页码中，行超出就超出吧。主要是列。

Answer 4

数据驱动分页：将内容拆分为可测量高度的独立区块，实时计算区块累积高度触发分页

双页流式布局：通过CSS Order+Flex反向控制奇偶页左右排列，保持书本式翻页视觉

动态占位策略：交互组件预埋固定高度占位符，弹窗采用Teleport脱离文档流避免布局干扰

想了一天，勉强有了点思路 大概就是自定义一些block 然后根据用途用component循环，具体能不能做出来还没有想好 这是大体的实现思路
背景部分:

<template>
    <div class="paged-document">
        <div class="paged-root">
       
                <div v-for="(item, index) in leftPages" :key="index" class="paged-pair">
                    <Page class="paged-left" :blocks="item" />
                    <Page v-if="rightPages[index]" class="paged-right" :blocks="rightPages[index]" />
                </div>
            </div>
    </div>
</template>

<script setup lang="ts">
import { computed } from 'vue';
import Page from './Page.vue';

const props = defineProps<{
    pages: Array<any>
}>();

const leftPages = computed(() =>
    props.pages.filter((_, i) => (i + 1) % 2 === 1)
);

const rightPages = computed(() =>
    props.pages.filter((_, i) => (i + 1) % 2 === 0)
);


</script>

<style scoped lang="scss">
.paged-document {
    width: 100%;
    min-height: 100%;
    background: #c8c8c8;
}

.paged-root{
    width: 1338.3px;
    margin: 0 auto;
    padding-top: 13.3px;
    padding-bottom: 13.3px;
}

.paged-pair{
    margin-bottom: 13.3px;
}

.paged-root:last-child{
    margin-bottom: none;
}
.paged-left{
    margin-right: 13.3px;
}
</style>

页面部分：

<template>
    <div class="page">
      <div class="page-padding">
        <div class="page-border page-border-top page-border-left"></div>
        <div class="page-border page-border-top page-border-right"></div>
      </div>
      <div class="page-content">
        <component
      v-for="(block, index) in blocks"
      :is="getComponent(block.type)"
      :key="index"
      :data="block.data"
    />
      </div>
      <div class="page-padding">
        <div class="page-border page-border-bottom page-border-left"></div>
        <div class="page-border page-border-bottom page-border-right"></div>
      </div>
    </div>
  </template> 
  
  <script setup lang="ts">
  import type { PropType } from 'vue';
import HeaderBlock from './HeaderBlock.vue';

 export type Block ={
  type: string;
  data: any;
}

 defineProps({
   blocks:{
   type:Array as PropType<Block[]>,
   default:[]
  }
});

function getComponent(type:string) {
  console.log(type)
  return {
    header: HeaderBlock
  }[type] || null
}

</script>

  <style scoped lang="scss">
  .page {
    width: 662.5px;
    height: 936.9px;
    background: white;
    box-shadow: 0 0 0 rgba(0, 0, 0, 0.2);
    overflow: hidden;
    position: relative;
    display: inline-block;
}
.page-padding{
  height: 66.7px;
  width: 100%;
  position: relative;
}
.page-border{
  display: inline-block;
  height: 20px;
  width: 20px;
}
.page-border-top{
  margin-top: 46.7px;
  border-bottom: 1px solid #aaaaaa;
}

.page-border-bottom{
  margin-bottom: 46.7px;
  border-bottom: 1px solid #aaaaaa;
}

.page-border-left{
  position: absolute;
  left: 80px;
  border-right: 1px solid #aaaaaa;
}
.page-border-right{
  position: absolute;
  right: 80px;
  border-left: 1px solid #aaaaaa;
}

.page-content{
  width: 510px;
  height: 803.5px;
  margin: 0 auto;
}
  </style>
  

然后就是组件部分,目前只写了一个header组件:

<!-- /renderer/src/components/HeaderBlock.vue -->
<template>
    <div :class="data.class" :style="data.style" v-on="normalizedHandlers">{{ data.data }}</div>
 </template>
  
  <script setup lang="ts">
import { computed } from 'vue';

  type Header={
    class:string;
    style: Record<string, string>;
    data: string;
    handlers?: {
    [eventName: string]: ((e: Event) => void) | Array<(e: Event) => void>;
  };
  }
  
  const props = defineProps<{
    data: Header;
  }>();

  const normalizedHandlers = computed(() => {
  const raw = props.data.handlers || {};
  const normalized: Record<string, (e: Event) => void> = {};

  for (const [event, handler] of Object.entries(raw)) {
    if (Array.isArray(handler)) {
      // 忽略空数组或无效函数
      if (handler.length > 0) {
        normalized[event] = (e: Event) => {
          for (const h of handler) h?.(e);
        };
      }
    } else if (typeof handler === 'function') {
      normalized[event] = handler;
    }
  }

  return normalized;
});
  </script>
  
  <style scoped lang="scss">
  /* 可添加样式 */
  </style>
  

外面传一个数组进去，后续分页的话就是对这个数组进行操作，至于分页的逻辑还没想好怎么弄:

 pages.value.push(
  [
    {
      type: 'header',
      data: {
        data: '标题',
        style:{
          fontSize:getFontSize('header'),
          textAlign:'center',
        },
        class:'myheader',
        handlers:{
          click: () => console.log('Clicked!'),
        }
      }
    }

这是大体的效果:
但是具体实现起来估计相当麻烦

核心逻辑：通过动态计算内容块高度，结合分页算法实现自动分页，双页排版通过 CSS 实现左右布局。
难点处理：不可分割内容整体移到下一页，可分割内容（如段落）按行分割，交互组件通过事件监听动态更新。
扩展性：支持多种内容类型（标题、表格、图片、交互组件），通过组件化实现灵活扩展。

<template>
  <div class="document">
    <div class="page-container">
      <div v-for="(page, index) in pages" :key="index" :class="['page', index % 2 === 0 ? 'left' : 'right']">
        <div v-for="block in page.blocks" :key="block.id" :ref="`block-${block.id}`">
          <h1 v-if="block.type === 'title'">{{ block.content }}</h1>
          <p v-if="block.type === 'paragraph'">{{ block.content }}</p>
          <img v-if="block.type === 'image'" :src="block.src" @load="onImageLoad(block.id)" />
          <vue-datepicker v-if="block.type === 'interactive' && block.component === 'DatePicker'" v-model="block.value" @change="onInteractiveChange" />
