With the development of the Internet, more and more information exists in the form of files, and the types of files are becoming more and more diverse. Among them, docx/xlsx/pdf and other types of files are relatively common. In a web page, if you need to preview these types of files, you need to use specific plug-ins or components to implement it. This article will introduce how to implement the preview function of docx/xlsx/pdf in Vue.
1. Basic Principles
Previewing files of docx/xlsx/pdf and other types in a web page usually requires converting the files into HTML format and then displaying them on the web page. This process can be implemented using some open source tools, such as Apache POI, iText, Aspose, etc. These tools can convert files of docx/xlsx/pdf and other types into HTML format and provide APIs for developers to use.
In Vue, we can use some third-party plug-ins or components to implement file preview function. For example, we can use the vue-pdf plugin to preview PDF files, use the xlsx plugin to preview Excel files, use the docx-to-html plugin to preview Word files, etc.
2. Preview PDF file
PDF files are a common document format that is often used to share documents on different operating systems and devices. Previewing PDF files in Vue can be done using the vue-pdf plugin. The plugin is based on development and supports a variety of browsers and devices.
- Install vue-pdf plugin
In Vue project, you can use the npm command to install the vue-pdf plugin:
npm install vue-pdf --save
- Introducing vue-pdf plugin
In Vue components that require the use of the vue-pdf plugin, you can introduce the vue-pdf plugin:
import VuePdf from 'vue-pdf'
- Using vue-pdf plugin
In the template of the Vue component, you can use the vue-pdf plugin:
<vue-pdf :src="pdfUrl"></vue-pdf>
where pdfUrl is the URL address of the PDF file.
- Things to note
When previewing PDF files using the vue-pdf plugin, you need to pay attention to the following points:
- PDF files need to be provided on the server side, and the local file path cannot be used directly;
- PDF files need to be provided using the https protocol, otherwise cross-domain problems may occur;
- PDF files need to be accessible, otherwise they may fail to load.
3. Preview Excel file
Excel files are a common spreadsheet format that is commonly used to store and process data. Previewing Excel files in Vue can be done using the xlsx plugin. This plugin can convert Excel files into HTML tables and provides APIs for developers to use.
- Install xlsx plugin
In Vue project, you can use the npm command to install the xlsx plugin:
npm install xlsx --save
- Introducing xlsx plugin
In Vue components that require the use of the xlsx plugin, you can introduce the xlsx plugin:
import XLSX from 'xlsx'
- Using the xlsx plugin
In the methods of Vue components, you can use the xlsx plugin:
export default {
data() {
return {
sheetData: []
}
},
methods: {
loadExcel(file) {
const reader = new FileReader()
= (e) => {
const data =
const workbook = (data, { type: 'binary' })
const sheetName = [0]
const sheet = [sheetName]
const sheetData = .sheet_to_json(sheet, { header: 1 })
= sheetData
}
(file)
}
}
}Among them, the loadExcel method can read the Excel file and convert it into HTML table format. When using this method, you need to pass in an Excel file object.
- Things to note
When previewing Excel files using the xlsx plugin, you need to pay attention to the following points:
- Excel files need to be provided on the client side, and you can use the input[type=file] control to select files;
- Excel files need to use xlsx format, and there may be compatibility issues in xls format;
- Excel files need to ensure that the data is formatted correctly, otherwise there may be conversion errors.
4. Preview Word files
Word files are a common text format that is often used to write and edit documents. Previewing Word files in Vue can be done using the docx-to-html plugin. This plugin can convert Word files into HTML format and provides API for developers to use.
- Install the docx-to-html plugin
In Vue project, you can use the npm command to install the docx-to-html plugin:
npm install docx-to-html --save
- Introducing docx-to-html plugin
In Vue components that require the docx-to-html plugin, you can introduce the docx-to-html plugin:
import DocxToHtml from 'docx-to-html'
- Use the docx-to-html plugin
In the methods of Vue components, you can use the docx-to-html plugin:
export default {
data() {
return {
htmlData: ''
}
},
methods: {
loadDocx(file) {
const reader = new FileReader()
= (e) => {
const data =
const converter = new DocxToHtml()
(data).then((result) => {
= result
})
}
(file)
}
}
}Among them, the loadDocx method can read Word files and convert them into HTML format. When using this method, you need to pass in the Word file object.
- Things to note
When previewing Word files using the docx-to-html plugin, you need to pay attention to the following points:
- Word files need to be provided on the client side, and you can use the input[type=file] control to select files;
- Word files need to use docx format, and compatibility issues may occur in doc format;
- Word files need to ensure that the data is formatted correctly, otherwise there may be conversion errors.
5. Summary
This article introduces how to implement the preview function of docx/xlsx/pdf in Vue. During the implementation process, you need to pay attention to the format and conversion method of the file, as well as the usage methods and precautions of plug-ins and components. Through these methods, various types of files can be easily previewed in Vue, improving user experience and work efficiency.
