Interacting with page scripts - Archive of obsolete content
how to send messages between content scripts and page scripts sharing objects with page scripts there are two possible cases here: a content script might want to access an object defined by a page script a content script might want to expose an object to a page script access objects defined by page scripts to access page script objects from content scripts, you can use the global unsafewindow object.
... with unsafewindow you can see javascript objects that have been defined by page scripts, and if a page script has modified the behavior of native dom functions, you'll get the modified version of them as well.
... in this example a page script adds a string variable foo to the window: <!doctype html"> <html> <head> <script> window.foo = "hello from page script" </script> </head> </html> the content script can see this object if it uses unsafewindow.foo instead of window.foo: // main.js var tabs = require("sdk/tabs"); var mod = require("sdk/page-mod"); var self = require("sdk/self"); var pageurl = self.data.url("page.html") var pagemod = mod.pagemod({ include: pageurl, contentscript: "console.log(unsafewindow.foo);" }) tabs.open(pageurl); be careful using unsafewindow: you can't rely on any of its properties or functions being, or doing, what you expect.
