Chrome extensions: variable undefined in chrome extension even though it exists in console

由 落花浮王杯 提交于 2019-12-13 05:19:21
问题 In my content scripts for my chrome extension, I dynamically load a external js file onto a html page once it is finished loading. This js file I load will define a variable called rfk . I have a set Interval for when rfk is defined, it will execute a script. However, even after succesfully loading the page, my content script will never find rfk to be defined, even though I can check through the browser console and find that rfk exists. "content_scripts": [ { "matches": ["*://www.att.com/*"],

由 我的梦境 提交于 2019-12-13 02:09:50
问题 I'm attempting to create a Chrome extension which will add a parameter to the end of a URL if the URL matches a given pattern ( *://*.mydomain.com/s/* ). Below is the manifest file and background script I have, but I cannot get it working.

IFrame in content script. How to communicate with main.js?

由 纵然是瞬间 提交于 2019-12-12 16:01:59
问题 My Firefox add-on opens Fancybox (type: "iframe") from a content script (page-mod). In the Fancybox I show my own HTML page ( my_fancybox_stuff.html ) that is located in my own server. Now, from the my_fancybox_stuff.js (javascript of my_fancybox_stuff.html ), can I send a message to the add-on's main.js ? Or to the content script that opened the Fancybox? I was hoping the global 'self' object to be accessible from my_fancybox_stuff.js as it is accessible from the content script that opened

Auto-load bookmarklet when in webpage as a Google Chrome extension

由 限于喜欢 提交于 2019-12-12 02:51:38
问题 Basically I made a bookmarklet, and I'd like it to run when a certain wildcarded URL is opened. For some reasons it won't simply run as javascript in a chrome extension, and I'm tired of trying.

However, I do not know how to make this. One
