监听文件上传事件:在React组件中,可以使用元素来创建一个文件上传的输入框,并为其添加一个onChange事件监听器。 代码语言:txt 复制 处理文件上传事件:在handleFileUpload函数中,可以获取到用户选择的文件,并执行相应的操作。例如,可以将文件发送到服务器进行处理,或者在客户端进行一些预览操作。 代码语言:txt 复制const...
接下来,我们需要创建一个文件上传组件,用于选择文件并触发上传操作。 在src文件夹内创建一个新的组件文件FileUpload.js,并添加如下代码: // src/FileUpload.jsimportReact,{useState}from'react';importaxiosfrom'axios';constFileUpload=()=>{const[file,setFile]=useState(null);// 文件状态constonFileChange=(e...
const res = await checkChunkUploadComplete({ filename: sourceFile.name, file_size: sourceFile.size, chunks, fileHash, user_id: initialState?.currentUser?.id || '', }); const { code, message: resMessage, result } = res; if (code === 0) { ...

const handleUpload = () => { files.forEach((file) => { const reader = new FileReader(); reader.onload = (event) => { const fileContent = event.target.result; // 在这里可以对文件内容进行处理或上传到服务器 console.log(fileContent); ...
class SendModal extends React.Component {//...//点击开始上传handleUpload = () =>{//获取iframe容器和这个报告的IDconst iframeContainer =getIframeContainer(); const iframeId= `iframe_${this.state.id}`;//iframe的load事件回调,执行该回调后开始执行this.createAndUpload()const onloadCallback = ()...

点击上传代码十分简单,就是利用input[type="file"]的能力唤起文件选择框,然后做一个自己喜欢的容器,把input框藏起来,点击容器的时候模拟input框点击即可,multiple属性是用来做多文件上传的。 拖拽上传 const handleDrop = (event) => { event.preventDefault(); ...
