How to use HTMLDocx to generate Word documents in Vue

In recent years, with the rapid development of front-end technology, more and more applications need to generate the content in the front-end page into Word documents for convenience Users download and share. In the Vue project, we can use HTMLDocx, a powerful library, to achieve this requirement. This article will introduce how to use HTMLDocx in Vue to generate Word documents, and attach corresponding code examples.

Install HTMLDocx

First, we need to install the HTMLDocx library in the Vue project. Enter the project root directory on the command line and execute the following command:

npm install htmldocx --save

After the installation is complete, we can use HTMLDocx to generate Word documents in the Vue project.

Writing a method to generate documents

In the Vue project, we can create a new component named "WordGenerator" to write a method to generate documents. In this component, we need to import the HTMLDocx library and define a method to generate a Word document.

<template>
  <div>
    <button @click="generateDocument">生成Word文档</button>
  </div>
</template>

<script>
import htmldocx from "htmldocx";

export default {
  methods: {
    generateDocument() {
      const content = "<div><h1>Hello, World!</h1></div>"; // 此处为需要生成为Word文档的HTML内容

      const docx = htmldocx.asBlob(content);

      const downloadLink = document.createElement("a");
      downloadLink.href = URL.createObjectURL(docx);
      downloadLink.download = "document.docx";
      downloadLink.style.display = "none";
      document.body.appendChild(downloadLink);
      downloadLink.click();
      document.body.removeChild(downloadLink);
      URL.revokeObjectURL(docx);
    },
  },
};
</script>

In the above code, we trigger the generateDocument method by clicking a button. In this method, we define an HTML string as the content of the Word document to be generated.

Then, we use the htmldocx.asBlob method to convert the HTML content into a Blob object of the Word document. Next, we create a <a> tag as a download link, set its href attribute to URL.createObjectURL(docx), and set download The attribute is "document.docx", indicating the name of the file to be downloaded. Then, we add the <a> tag to the page and simulate clicking on it to download the generated Word document. Finally, we remove the <a> tag from the page and use URL.revokeObjectURL to release the previously created URL object.

Using the method of generating documentation in Vue

Now, we can use the method we wrote to generate documentation in other components of the Vue project. Suppose we use this method in a component named "HomePage". We need to add a button to the template and specify its click event as the generate document method we just wrote.

<template>
  <div>
    <button @click="generateDocument">生成Word文档</button>
  </div>
</template>

<script>
import WordGenerator from "@/components/WordGenerator";

export default {
  components: {
    WordGenerator,
  },
};
</script>

In the above code, we introduced the "WordGenerator" component written before and registered it as a subcomponent of the HomePage component. Then, we trigger the method of generating the document through the button click event in the template.

So far, we have successfully used HTMLDocx to generate Word documents in the Vue project. When the user clicks the corresponding button, the generated Word document will be automatically downloaded.

Summary

This article introduces how to use HTMLDocx to generate Word documents in Vue. First, we need to install the HTMLDocx library and then write a method to generate the document. Finally, using the document generation method in the Vue project can realize the function of generating and downloading Word documents in the front-end page.
