问题 I'm trying to make a Chrome extension. For that extension, I need some info that is dynamically created, but I want that data to be added even later on (on a different page). This is some sort of data that i want to be always accessible (when the plugin runs): var villages = new Array(); villages[0][0] = "village1"; villages[0][1] = "1325848"; villages[1][0] = "village2"; villages[1][1] = "8744351"; villages[2][0] = "village3"; villages[2][1] = "8952187"; As you can see, the array is multi

问题 I'm writing a Chrome app that needs to have an SSL socket with client authentication. I have done this before in Java with the same set of trust store and key store.

In Chrome app, try both the legacy socket API and the new sockets.tcp API. Always receiving error ERR_SSL_CLIENT_AUTH_CERT_NEEDED . But I think I already have the correct client cert and CA in the

问题 I am writing a Chrome extension and I need to pass in the value that the user has selected on the website to my server. I am using the code window.getSelection() which returns a range object. I am using JSON to pass the range object back to my server but it is not working. I am new to this, but I think the problem lies with the fact that you can only pass in text with JSON, and the range object includes both the DOM structure (which is not text) and the actual text selection (which is text).

问题 I am making a small Chrome extension. I would like to use chrome.storage but I can't get it to delete multiple items (array) from storage. Single item removal works. function clearNotes(symbol) { var toRemove = "{"; chrome.storage.sync.get(function(Items) { $.each(Items, function(index, value) { toRemove += "'" + index + "',"; }); if (toRemove.charAt(toRemove.length - 1) == ",") { toRemove = toRemove.slice(0,- 1); } toRemove = "}"; alert(toRemove); }); chrome.storage.sync.remove(toRemove,

问题 In my content script, I want to monitor which file a is getting uploaded to a web application. I monitor "change" event for any "input:file" element. It works on any site (such as Gmail) that uses "input:file". However sites like imgur, use SWFUpload mechanism. I tried to capture "fileQueued" event on element that I suspected to be swfupload. But that did not work. How can I capture file upload event for sites that use swfupload? Are there any other plugins that manage file uploading that I

问题 I'm distributing a chrome extension through the Chrome web store and I'm having trouble finding anyplace where the web store tells me how many "total installs" my extension has. I want to be able to know how many people in total have installed my extension since I first uploaded it. Some quick searching on google yielded the following article in the google help section, but I can't find a "details" page that actually shows the "weekly installs" figure. Check it out here. In addition, there's

问题 I am developing Google Chrome extension. Each time my JavaScript source changes, I find myself having to click "load unpacked extension" again to have the changes take effect.

For example, if user types www.google.com , I would like to append ?q=query to url (final: www.google.com?q=query . Thanks 回答1: The webRequest API might be what you need.
