React+antd重写博客网站,在编写一个表单页面时遇到了如下报错:Warning: [antd: Upload] `value` is not a valid prop, do you mean `fileList image.png 在查找后解决方法如下: image.png 报错是因为Upload组件被嵌套在表单中造成的只需要在对应的Form.Item组件上添加 valuePropName="fileList
File对象兼容性.png 二、FileList 对象 1. 概念介绍 FileList 对象是一个类数组对象,每个成员都是一个 File 实例,主要出现在两种场合: 通过 <input type="file"> 控件的 files 属性,返回一个 FileList 通过拖放文件,查看 DataTransfer.files 属性,返回一个 FileList 实例。 实例属性和方法 3.1 实例属性 实例只有一个属性: FileList.length:返回列表中的文件数量。 FileList对象兼容性.png 5.
Sending Encrypted Filelist"表示此勒索软件在发送加密文件列表给受害者之前,对文件进行加密。

"></el-upload>内部实现:watch: { fileList: { immediate: true, handler(fileList) { this.uploadFiles 展开即可,不要同其提供的 filelist 混淆使用。 // on-change 事件handlerChange (file, filelist) { this.fileList.push(file) /* 或者其他操作,无需通过 filelist 处理 handleChange (file, fileList) { // 只保留一个文件 if (fileList.length > 1) { // 这里直接改了引用值 组件内部 uploadFiles filelist 即可(常见问题2中我们有提及,内部会watch该 filelist)总结el-upload 提供了诸多处理,为我们日常开发提供了便利性,同时也存在着一些边界没有处理。
