Implementing HTML to HTMLDocx conversion in Vue: a simple and efficient document generation method

Conversion of HTML to HTMLDocx in Vue: a simple and efficient method of document generation

In modern Web development, generating documents is a common requirement. HTML is the basic structure of Web pages, and DOCX is a common office document format. In some cases, we may need to convert HTML to DOCX format to meet specific needs. This article will introduce a simple and efficient method to use Vue to convert HTML to HTMLDocx.

First, we need to install a JavaScript library called html-docx-js, which provides the function of converting HTML to HTMLDocx. The library can be installed through the following command:

npm install html-docx-js

After the installation is complete, we can use the following code to convert HTML to HTMLDocx:

// 导入html-docx-js库
import htmlDocx from 'html-docx-js'

// 定义一个方法，接受HTML字符串作为参数，并返回一个Promise对象
const convertToDocx = (html) => {
  return new Promise((resolve, reject) => {
    try {
      // 使用html-docx-js库将HTML转换为HTMLDocx格式
      const docx = htmlDocx.asBlob(html)
      
      // 创建Blob URL
      const url = URL.createObjectURL(docx)
      
      // 解决Promise并返回Blob URL
      resolve(url)
    } catch (error) {
      // 捕获错误并拒绝Promise
      reject(error)
    }
  })
}

In the above code, we imported html-docx -js library and defines a method called convertToDocx. This method accepts an HTML string as a parameter and returns a Promise object. Inside the method, we convert the HTML to HTMLDocx format using the asBlob method of the html-docx-js library. We then create a Blob URL and resolve the Promise and return the URL. If an error occurs, we will catch the error and reject the Promise.

Next, we can use the convertToDocx method in the Vue component to generate the HTMLDocx document. Here is an example:

<template>
  <div>
    <!-- 在这里放置你的HTML内容 -->
  </div>
  
  <button @click="generateDocx">生成文档</button>
</template>

<script>
import { saveAs } from 'file-saver'
import convertToDocx from './utils/convertToDocx'

export default {
  methods: {
    async generateDocx() {
      try {
        // 调用convertToDocx方法将HTML转换为HTMLDocx格式
        const docxUrl = await convertToDocx(this.$el.innerHTML)
        
        // 使用file-saver库下载生成的文档
        saveAs(docxUrl, 'document.docx')
      } catch (error) {
        console.error(error)
      }
    }
  }
}
</script>

In the above code, we import a file saving library named saveAs in order to download the generated HTMLDocx document to the local. Then, we call the convertToDocx method in the generateDocx method of the Vue component to convert the HTML to HTMLDocx format. Finally, we use the saveAs method to save the generated document locally with the file name document.docx.

With the above code, we can easily convert HTML to HTMLDocx document and download the generated document with the click of a button. This method is simple and efficient, and is suitable for Vue-based projects.

Summary:
This article introduces a simple and efficient method to use Vue to convert HTML to HTMLDocx. By using the html-docx-js library and the file-saver library, we can easily convert HTML to HTMLDocx documents and download them locally. This method is very practical for Vue projects that need to generate documentation. Hope this article can be helpful to you!
