问题描述

我正在尝试预览不同的文件类型，但无法正常工作.默认情况下，jQuery File upload仅预览图像文件(jpeg | png | gif).但是我需要显示其他文件类型的预览，例如(pdf | doc | pptx | txt).如何做到这一点? 我尝试更改此设置，但没有运气

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

现有代码:

previewFileTypes: /^image\/(gif|jpeg|png)$/,

我的更改:(仍然不显示pdf，doc，ppt的预览)

My Change: (Still does not show preview for pdf, doc, ppt)

previewFileTypes: /^.*\/(gif|jpeg|png|pdf|PDF|pptx|plain|doc|docx)$/,

推荐答案

预览用于显示图像. PDF和文档文件类型不是图像，因此无法显示.从文档:

The preview is for showing images. The PDF and document file types are not images, and cannot be shown. From the documentation:

预览图像，音频和视频:图像，音频和视频的预览 在使用支持以下功能的浏览器上传之前，可以显示文件 必需的API.

Preview images, audio and video: A preview of image, audio and video files can be displayed before uploading with browsers supporting the required APIs.
