Online PDF viewer

Given a PDF, how can I display that on the browser and allow certain user interactions (e.g. zooming, etc.) and programmatic actions (e.g. respond to events triggered within the document, etc.) with it? I'm looking for a library, plugin, etc. I'm using jQuery 开发者_运维百科and PHP. Suggestions?
