Chrome Extension ContextMenu for PDF
google-chrome, google-chrome-extension, javascript
Solution
I'm guessing that you want to add a context menu only when a PDF is shown in a tab, right? Just asking because I thought at first that you wanted to add the context menu on links to PDF files, which is indeed possible*. (as you probably know)
I couldn't find a way to do this directly, however one alternative could be to listen to `chrome.tabs.onActivated` and add or remove your context menu based on if the current URL matches a PDF file. One drawback is that it means asking for the `tabs` permission which might looks scary to users. ("This extension can access your tabs and browsing activity" or something like that)
*for the curious, you do it like this:
chrome.contextMenus.create({
title: "Hello world",
contexts: ["link"],
targetUrlPatterns: ["*://*/*.pdf"]
});
(you would add the other options that interest you of course)
Problem
I'm developing a extension for the chrome browser and i want to add a specified contextmenu for pdf documents. I also add to specified contextmenus for the type "page" and "image". If i set the type to "all" then there is a contextmenu, but not specified for pdf documents. Is it possible to add a specified contextmenu for pdf documents or should i use a the type "all" an it make switch case in the clickEventHandler?! See more at: http://developer.chrome.com/extensions/contextMenus.html These are the "file" types: ``` contexts ( optional array of enum of "all", "page", "frame", "selection", "link", "editable", "image", "video", "audio", or "launcher" ) ```
