HTMLDocx based on Vue: an easy way to edit and export documents online

Introduction:
In actual work, we often need to edit and export documents, such as reports, contracts, etc. This article will introduce a Vue-based HTMLDocx method that can help us quickly implement online editing and exporting documents.

1. Preparation
   Before we start, we need to prepare the following tools and environment:
2. Vue CLI: used to create Vue-based projects
3. HTMLDocx plug-in :Plugin for converting HTML to Docx format

Install Vue CLI:

npm install -g @vue/cli

Create project:

vue create html-docx-demo

Install HTMLDocx plugin:

npm install html-docx-js

2. Create an editor component
   In order to implement the function of editing documents online, we need to create an editor component. In the component, we can use Vue's v-model directive to implement two-way data binding to preview the editing results in real time.

Create a file named Editor.vue in the src/components directory and add the following code:

<template>
  <div>
    <textarea v-model="content" @input="handleInputChange"></textarea>
    <div class="preview" v-html="previewHTML"></div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      content: '',
      previewHTML: ''
    }
  },
  methods: {
    handleInputChange() {
      // 将输入的内容渲染为HTML
      this.previewHTML = this.content;
    }
  }
}
</script>

<style scoped>
textarea {
  width: 100%;
  height: 200px;
}

.preview {
  margin-top: 20px;
  border: 1px solid #ccc;
  padding: 10px;
}
</style>

3. Export Document
   Next, we need to add an export button to export the edited document to Docx format. First, add a button in the Editor.vue component and bind a click event.

<button @click="exportDocx">导出文档</button>

Then, in the methods area, add the method to export the document.

exportDocx() {
  // 将HTML内容转换为Docx格式
  const docx = window.htmlDocx.asBlob(this.content);

  // 下载文档
  const url = window.URL.createObjectURL(docx);
  const link = document.createElement('a');
  link.href = url;
  link.download = 'document.docx';
  link.click();
}

4. Integration component
   In App.vue, integrate the editor component and the export button component.

<script>
import Editor from './components/Editor.vue';

export default {
  name: 'App',
  components: {
    Editor
  },
  methods: {
    exportDocx() {
      // 调用编辑器组件中的导出方法
      this.$refs.editor.exportDocx();
    }
  }
}
</script>

5. Run the project
   Finally, run the project with the following command:

npm run serve

Open in a browserhttp://localhost: 8080, you can see a text editing box and export button. Enter content in the edit box and click the export button to export the content into a Docx format document.

Summary:
This article introduces a Vue-based HTMLDocx method, which realizes a simple way to edit and export documents online by creating an editor component and export function. We can customize and extend the editor components according to actual needs to meet different application scenarios.
