Vue and HTMLDocx: Efficient methods and practical tips for implementing document export

Exporting documents is one of the common requirements in many web applications. In this article, we will discuss efficient methods and practical techniques for document export using Vue and HTMLDocx.

HTMLDocx is an HTML and JavaScript-based library that converts HTML documents to Microsoft Word’s .docx file format. It provides a simple and easy-to-use API that allows us to easily export HTML content to .docx files.

Next, let’s take a look at how to use HTMLDocx to implement document export in a Vue application.

The first step is to install the HTMLDocx library. We can install it through npm:

npm install htmldocx

After the installation is complete, we can import and use HTMLDocx in the Vue component.

import htmlDocx from 'htmldocx'

export default {
  methods: {
    exportDocument() {
      const htmlContent = '<h1>这是一个导出的文档示例</h1>'
      
      const docx = htmlDocx.asBlob(htmlContent)
      const blobUrl = URL.createObjectURL(docx)
      
      const link = document.createElement('a')
      link.href = blobUrl
      link.download = 'document.docx'
      link.click()

      URL.revokeObjectURL(blobUrl)
    }
  }
}

In the above code, we define a method exportDocument, which is used to export documents. First, we create a string htmlContent that contains the HTML content. We then use the asBlob method of the htmlDocx library to convert the HTML content into a Blob object of the .docx file. Next, we create a URL object and use the createObjectURL method to convert the Blob object into a URL containing the file download link. Then, we create an a tag and use the URL object as the value of the href attribute. Set the download attribute to the desired file name. Finally, we call the click method to trigger the download operation and use the revokeObjectURL method to release the URL object.

In the template of the Vue component, we can add a button to call the exportDocument method:

<template>
  <div>
    <button @click="exportDocument">导出文档</button>
  </div>
</template>

Now, when the user clicks the "Export Document" button, a file named document will be downloaded. docx document, which contains a content titled "This is an example of an exported document."

In addition to basic text and titles, HTMLDocx also supports more complex features such as tables, images, and styles. Let's look at a more complex example:

export default {
  methods: {
    exportDocument() {
      const htmlContent = `<h1>学生列表</h1>
                          <table>
                            <thead>
                              <tr>
                                <th>姓名</th>
                                <th>年龄</th>
                                <th>性别</th>
                              </tr>
                            </thead>
                            <tbody>
                              <tr>
                                <td>张三</td>
                                <td>20</td>
                                <td>男</td>
                              </tr>
                              <tr>
                                <td>李四</td>
                                <td>22</td>
                                <td>女</td>
                              </tr>
                            </tbody>
                          </table>`
      
      const docx = htmlDocx.asBlob(htmlContent)
      const blobUrl = URL.createObjectURL(docx)
      
      const link = document.createElement('a')
      link.href = blobUrl
      link.download = 'student-list.docx'
      link.click()

      URL.revokeObjectURL(blobUrl)
    }
  }
}

In the above code, we use the HTML table tag to display a list of students. The resulting document will contain a large header titled "Student List" and a table containing names, ages, and genders.

In this way, we can use HTMLDocx in Vue applications to achieve efficient methods and practical techniques for document export. We can create documents with various contents and styles according to specific needs and export them as .docx files to meet the needs of users.
