HTML - Open local PDF in a new window using a button
提问by giroxasmnl
I'm trying to open a pdf file using a button in my project.
我正在尝试使用项目中的按钮打开 pdf 文件。
Given this code:
鉴于此代码：
<button type=submit class="btn btn-danger" onclick=" window.open('file:////C:\Users\data'); return true;"> PDF </button>
It just opens a about:blank page. What seems to be wrong?
它只是打开一个 about:blank 页面。似乎有什么问题？

You shouldn't be linking to a local file on your own pc. You need to upload the file to your server, like you would do with images, and then link to the path that you place it in.
您不应该链接到您自己电脑上的本地文件。您需要将文件上传到您的服务器，就像处理图像一样，然后链接到您放置它的路径。
You should also be able to use target="_blank"for this rather than onclick.
Here is an example set up for the html:
您还应该能够为此使用target="_blank"而不是 onclick。这是为 html 设置的示例：
<a href="/books/a-great-book.pdf" target="_blank">
