需求
上一篇写了excel文档解析,顺便就看看word文档。
解决问题
1.前端在浏览器预览word文档。
2.可以直接提取word文档内容
利用技术
预览文档--docx-preview
<script src="https://cdn.jsdelivr.net/npm/docx-preview@0.1.15/dist/docx-preview.js"></script>
提取文档内容--mammoth
<script src="https://cdn.bootcdn.net/ajax/libs/mammoth/1.6.0/mammoth.browser.min.js"></script>
预览文档实现过程
// HTML
<div id="preview"></div>
实现预览功能
renderAsync接收四个参数
1.document: 数据格式可以为Blob | ArrayBuffer | Uint8Array, // could be any type that supported by JSZip.loadAsync
2.bodyContainer: 渲染的区域
3.styleContainer: 通常用于指定一个HTML元素,该元素将用于包含和管理渲染文档所需的样式信息,包括字体、颜色、布局等。
4.options:{} 具体参数看文档
// JavaScript
const onWord = (event) => {
let reader = new FileReader();
let file = event.target.files[0];
let options = { inWrapper: false, ignoreWidth: true, ignoreHeight: true }
docx.renderAsync(file, document.getElementById("preview"), null, options)
}
提取word文档实现过程
1.extractRawText--转文字;
2.convertToHtml--转HTML;
3.convertToMarkdown--转Markdown 文档
const onWord = (event) => {
let reader = new FileReader();
let file = event.target.files[0];
if (file) {
reader.onload = function (e) {
const data = e.target.result;
// 转文字
mammoth.extractRawText({ arrayBuffer: data }).then(function (displayResult) {
wordData.value = displayResult.value
}).done();
// 转HTML
mammoth.convertToHtml({ arrayBuffer: data }).then(function (displayResult) {
console.log(displayResult);
}).done();
// 转Markdown 文档。
mammoth.convertToMarkdown({ arrayBuffer: data }).then(function (displayResult) {
console.log(displayResult);
}).done();
};
reader.readAsArrayBuffer(file);
}
}
