问题
I am trying to preview different file types, but Its not working. By default jQuery File upload only previews Image files(jpeg | png | gif). But I need to display a preview for Other File types such as (pdf | doc | pptx | txt). How to achive this?? I tried changing this, but no luck
Existing Code:
previewFileTypes: /^image\/(gif|jpeg|png)$/,
My Change: (Still does not show preview for pdf, doc, ppt)
previewFileTypes: /^.*\/(gif|jpeg|png|pdf|PDF|pptx|plain|doc|docx)$/,
回答1:
The preview is for showing images. The PDF and document file types are not images, and cannot be shown. From the documentation:
Preview images, audio and video: A preview of image, audio and video files can be displayed before uploading with browsers supporting the required APIs.
