Resumable.js – 基于 HTML5 File API 的文件上传

Resumable.js 是一个 JavaScript 库,通过 HTML5 文件 API 提供,稳定和可恢复的批量上传功能.在上传大文件的时候通过每个文件分割成小块,每块在上传失败的时候,上传会不断重试直到程序完成.这允许上传到本地或服务器的网络连接丢失后能够自动恢复上传. 此外,它允许用户暂停,恢复,甚至恢复上传不失状态,因为只有目前上传块将被中止,而不是整个上传.Resumable.js 除了 HTML5 文件 API 意外,没有任何外部依赖.目前,这意味着支持仅限于 Firefox 4+…

js获取input file路径改变图像地址

js清空input file值

项目进行导入操作,如果第一次导入某个文件会触发导入操作,但是第二次导入重复该文件,不会触发操作. 分析了原因,是因为上一次file里选择的文件路径值与本次选择的文件路径值是一样的,值没有改变所以导致file不会触发submit事件. 解决这个问题的思路是每次创建完导入数据后把file的路径值清空,但浏览器的安全机制限制不可以直接用js修改file的value为有效值,解决方法是设置file的value为空字符,或者把file的html重新初始化来解决清空的问题. var file = docum…
