由 微笑、不失礼 提交于 2019-12-19 10:29:17
问题 I want to share current opened tab url on facebook wall from chrome extension. For that, I was using https://facebook.com/share.php earlier which was giving me login option first and then share box. Since facebook has deprecated this method, how can I post/share on my wall from chrome extension? FB.api is another option but for that I may have to authenticate with facebook first. How can I achieve this from chrome extension? 回答1: You can use feed dialog, find more detail here This is a direct

Chrome native messaging doesn't accept messages of certain sizes (Windows)

由 被刻印的时光 ゝ 提交于 2019-12-19 10:17:40
问题 I'm developing a Chrome extension working with native messaging host. It works in most cases, but I have found a strange behavior when I send messages of certain sizes. It seems that message is dropped, when the size is between 2560 and 2815 bytes (A00 and AFF in hex). All subsequent messages are also not arriving, which suggests that the stream is corrupted for some reason. Here is a stripped down Python native messaging app, which can be used to test it: import sys import struct def output

问题 I have a great working chrome extension now. It basically loops over a list of HTML of a web auction site, if a user has not paid for to have the image shown in the main list. A default image is shown. My plugin use a jQuery Ajax request to load the auction page and find the main image to display as a thumbnail for any missing images. WORKS GREAT.

由 ￡可爱￡侵袭症＋ 提交于 2019-12-19 09:56:30
问题 I need to access the DOM of a web component that has a closed Shadow DOM for some Selenium testing. I've read in several references that you can override Element.prototype.attachShadow on the document startup in order to change the Shadow from closed to open. In order to do this, I created a Chrome Extension. Below is my manifest.json : { "name": "SeleniumTesting", "description": "Extension to open closed Shadow DOM for selenium testing", "version": "1", "author": "SeleniumTesting", "manifest

Communication from an injected script to the content script with a response

由 蓝咒 提交于 2019-12-19 09:09:21
问题 Following this question, communicating between an injected script and content script can be made that way: // Content script window.addEventListener("getChromeData", function(data) { // do Chrome things; }, false); // Injected script window.dispatchEvent(new CustomEvent("getChromeData", {data: 'whatever'})); I wanted to know if there is a way to make use of returned data into the injected script, using a promise or a callback mechanism? 回答1: The communication back is again done with an event.

chrome.extension.getBackgroundPage() returns null after awhile

由 ぃ、小莉子 提交于 2019-12-19 09:05:58
问题 When my chrome extension loads on chrome startup, everything seems to be ok and chrome.extension.getBackgroundPage() returns the right value (lunched from popup.js). But after awhile (2-3 minutes), especially if the browser is let alone, the function returns null. Only closing and re-opening chrome solves the problem. I tried to manipulate it by: if (chrome.extension.getBackgroundPage() == null) window.location.reload(true); As suggested at Why does chrome.extension.getBackgroundPage() return

How to tell if a Chrome extension is installed by a real user vs. by me during development?

由 孤街醉人 提交于 2019-12-19 07:49:50
问题 I'm using Analytics in my Chrome extension. I want to execute the analytics code only if the extension is being used by a real person (not me while I'm working on it). Are any of the following doable and which is the best? Identify whether the extension was installed packed or unpacked. I think this is the best because unpacked clearly means it's "in development" and it's not specific to my machine in any way. Can the extension know this programatically? Have the extension look for something
