问题 I have several async functions running. I want to wait for them all to finish before taking the next steps. Here's my code that I'm using to get all of the key/values from chrome.storage and the Promise.all() implementation. var promise1 = Promise.resolve(3); var promise2 = 42; var promise3 = new Promise(function(resolve, reject) { setTimeout(resolve, 100, 'foo'); }); var getAll = chrome.storage.sync.get(function(result) { console.log(result) }); Promise.all([promise1, promise2, promise3,

问题 Is there any chrome or firefox extension that allows javascript to create write files in client's PC? 回答1: What do you want to do? HTML5 has a File API.

问题 I'm new to creating chrome extensions. I want to test sending messages from a web page to an extension as described here: https://developer.chrome.com/extensions/messaging#external-webpage.

问题 I'm working on a chrome extension where I'd like to inject a content script into a list of urls. Usually I'd use the regular syntax: { "name": "My extension", ... "content_scripts": [ { "matches": ["http://www.google.com/*"], "css": ["mystyles.css"], "js": ["jquery.js", "myscript.js"] } ], ... } But for the match patterns I'd like to pull the array from a server. Is there a way to programmatically set the "matches" array (from the background.js file for example)? 回答1: As far as I know, you

I thaught the best way to do it is to use an extension to grab the message body (and some additional information) and then send that as a webrequest to a service for insertion into the database. But I have no idea how I should handle this. I followed some tutorials to get me started on chrome plugins but I can't find how to get the body of the
