问题 I've got a small problem. I want to read a var defined inside tag in DOM. <script id="foo"> var x = 1 </script> I can access it via: var script = document.querySelector("#foo"); But then what? Of course var x_value = script.x or var x_value = script.outerHTML.x doesn't work. So how can I get x's value then?

问题 How does one programmatically open the Developer Tools window of a Chrome extension's background page using the Chrome Extensions API? Essentially, I'm looking to achieve the programmatic equivalent of manually clicking on the "inspect background page" link of a given Chrome extension. 回答1: Interesting question.

问题 I want to know how can we obtain the cookies of the current page being accessed using a communication link between the content script and background page.

There are many examples on Stack Overflow for example: Chrome Extension: how to capture selected text and send to a web
