FILTERMANAGER 文件系统筛选器FILEINFO成功加载后 系统卡死 其他硬件还在运行

Posted 2023-03-19

求解

参考技术A 文件筛选器开启的瞬间，CPU会过载运行，如果在这个地方卡死，很有可能是磁盘有坏道或者内存有错误，请进行磁盘坏道检测和修复

＜input type=“file“＞ accept属性筛选文件类型上传

关于form表单上传文件类型的筛选，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:

 

1	<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

如果不限制上传图片的格式可写成：accept="image/*"
