如果你不希望⽤户上传任何类型的⽂件, 你可以使⽤ input 的 accept 属性.
设置⽀持 .doc / .docx / .xls / .xlsx / .pdf 格式:梦见倒垃圾
<input type="file"accept=".doc,.docx,.xls,.xlsx,.pdf,application/msword,application/vnd.openxmlformats-officedocument.wordprocessingml.document">
如果需要⽀持 .png 等，则在 accept 添加上既可，都逗号分隔。
扩展知识：
accept 属性接受⼀个逗号分隔的 MIME 类型字符串, 如:
accept="image/png" or accept=".png" — 只接受 png 图⽚.
accept="image/png, image/jpeg" or accept=".png, .jpg, .jpeg" — PNG/JPEG ⽂件.
accept="image/*" — 接受任何图⽚⽂件类型.
accept=".doc,.docx,.xml,application/msword,application/vnd.openxmlformats-officedocument.wordprocessingml.document" — 接受任何 MS Doc ⽂件类型.
<input> type 类型为 file 的 input 元素使得⽤户可以选择⼀个或多个元素以提交表单的⽅式上传到服务器上，或者通过 Javascript 的 File API 对⽂件进⾏操作
