问题 I want to update a div with a list of anchors that I generate from a local database in chrome. It's pretty simple stuff, but as soon as I try to add the data to the main.js file via a callback everything suddenly becomes undefined. Or the array length is set to 0.

As a solution I saw putting that html to background.html and retrieving that code from popup.js: // listeners to save/restore

For each page, the console registers multiple logs...and I have no idea why. The scripts are simple: content.js chrome.runtime.sendMessage({hi: "hi"}, function(response) {}); //or //var port = chrome.runtime.connect({name: "test"}); //port.postMessage({hi: "hi"}); background.js chrome.runtime.onMessage

问题 I am creating a Google Chrome extension that does some basic search based on the choices provided. This is how it looks so far The problem is that there is a lot of white space on the sides which does not look good, especially because this is a popup and overlays on the current page.
