Yes, well, my file path was incorrectly written.
But this seems to depend on Adobe Reader.
If users don't have Adobe reader locally, they won't be able to use it.
Is there any other way?

Demo address in IE reported wrong Firefox can run, the effect is good, but feel very card. Does this depend on Adobe Reader?

It does not support IE, do not need Adobe Reader, pure HTML5 JS Library.

Or you can use Flash PDF reader so that the browser can support it, and Adobe Reader is not required.
