Currently I'm trying to pass an array from the context_script into my popup.html on a button click from the extension. However there have been complications which I can't seem to solve on my own, almost every single one of the implementation methods in SO and other sites don't seem to work out.
All I really need is to simply pass a single list from the context, into the JavaScript page that handles the extensions HTML interface.
background.js
"use strict";
function Master() {
firebase.initializeApp(config);
this.time = 0;
this.http_usage = this.get_http();
this.https_usage = this.get_https();
this.todays_usage = this.get_today_sites();
chrome.runtime.onMessage.addListener(function(message,sender,sendResponce) {
sendResponce("Hello world");
});
this.init();
}
manifest.json
{
"name": "Statistics",
"description": "Saves time and visitation data.",
"version": "1.0",
"manifest_version": 2,
"permissions": [
"activeTab",
"tabs",
"http://*/*",
"https://*/*",

"clipboardWrite",
"background"

"*://*/*"

"css": [

]
}
],
"browser_action": {
"default_title": "Statistics",
"default_popup": "popup.html"
}
}
popup.js
function get_data(){
let data = []
chrome.runtime.sendMessage({data:"giblist"}, function (responce) {
console.log(responce);
...
});
}
document.addEventListener('DOMContentLoaded', function () {
console.log("Loaded page");
firebase.initializeApp(config);
document.getElementById("showStatistics").addEventListener("click", get_data);
});

I created a js script that goes with my popup.html for a chrome browser extension I'm working on. It listens for a change in a slider value on the HTML and then sends a message to the content.js script with the new data. However, it seems I can't use sendMessage in this script. I'm using manifest v3.
Here's my js:
var slider = document.getElementById("slider");
let value = slider.value;
//function is called when the slider moves
changeSlider = function() {
value = slider.value;
update();
}
update = function() {
chrome.runtime.sendMessage({ message: "update", data: value });
}
Here's my manifest:
{
"manifest_version": 3,
"name": "e",
"version": "0.1",
"author": "e",
"homepage_url": "https://www.example.com",
"permissions": [
"contextMenus",
"activeTab",
"nativeMessaging"
],
"content_scripts": [
{
"matches": ["<all_urls>"],
"js": ["src/content.js"]
}],
"web_accessible_resources": [
{
"resources": ["src/*"],
"matches": ["<all_urls>"],
"use_dynamic_url": true
}],
"background": {
"service_worker": "src/background.js"
},
"action":
{
"default_popup": "src/popup.html",
"default_icon": "src/resources/icon.png"
},
"icons": {
"16": "src/resources/icon-16.png",
"32": "src/resources/icon-32.png",
"48": "src/resources/icon-48.png",
"128": "src/resources/icon-128.png"
}
}
And here's the console error I get whenever I adjust the slider:
additionally, my interpreter doesn't autofill chrome.runtime, so I assume something went wrong there. Help :D
I would like to know why and how to fix:
My code is being injected a few times while being o specific website, can't find why.
It should be injected only when visiting a specific url (it can be different for example tickets/*****).

Hello i am trying to create a chrome extension. It like tampermonky. It add some user script. But the problem is some variable show undefined, But when i use the same script on tampermonky there is no error.
My extension manifest.json is
{

"description": "It will say hello when a page finishied load.",
"version": "0.4",
"permissions": [
"tabs",
"<all_urls>",
"storage"
],
"browser_action": {
"default_icon": "icon.png"
},
"options_page": "options.html",
"content_scripts": [
{
"exclude_globs":[],
"include_globs":["*"],
"matches": [
"http://www.amazon.com/*",
"https://www.amazon.com/*"
],
"js": ["email.js"],
"run_at": "document_end"
}
],
"converted_from_user_script": true,
"manifest_version":2
}
and email.js is.
P.when("jQuery","ready").execute(function(t){
var i="http://www.amazon.com/gp/profile/A3U7NCDBQ95EJM/customer_email";
t.get(i,function(t){
var o=t.data.email;
console.log('o:'+o);
});
return t;
});
error massage is Uncaught ReferenceError: P is not defined
As you can see, I have a problem with onclick event in chrome extension and I need your help.
$(function jony() {
jQuery.each( jQuery('img'), function() {
jQuery(this).attr('src', 'urlimage');
});
});
chrome.browserAction.onClicked.addListener(function(tab) {
jony();
});
Manifest:
{
"manifest_version": 2,
"name": "Jonyzátor",
"description": "Change images on page to JoNy!",
"version": "1.0",
"browser_action": {
"default_icon": "icon.png",
"default_title": "Klikni na mě!"
},
"permissions": [
"activeTab",
"https://ajax.googleapis.com/"
],
"content_scripts": [ {
"js": [ "jquery.js", "jonyza.js"],
"matches": [ "http://*/*", "https://*/*"]
}]
}
The scope in which jony is defined is limited to $(); outside it's simply undefined.
function jony() {
jQuery.each( jQuery('img'), function() {
jQuery(this).attr('src', 'urlimage');
}
$(jony); // Will execute on page load
// and you can still use it here
I'm not sure it was the logic you intended - do you want it to run both at page load AND when you click?
You can't use browserAction API in content scripts. The proper place for it would be a background (or event) script, and then you can message your content script to do something.
this is not firing at all when the page finishes loading. Basically when I click the browser action button, it will trigger it on, and on page load, it will run a script. In my background.js
var toggle = false;
chrome.browserAction.onClicked.addListener(function(tab) {
toggle = !toggle;
if(toggle){
chrome.browserAction.setIcon({path: "icons/logo.png", tabId:tab.id});
// chrome.tabs.executeScript(tab.id, {file:"SCRIPT.user.js"});
chrome.tabs.executeScript(tab.id, {code:"alert('aaxxxbbaa')"});
}
else{
chrome.browserAction.setIcon({path: "icons/icon48.png", tabId:tab.id});
chrome.tabs.executeScript(tab.id, {code:"alert('bbdxdb')"});
}
});
var filter = {'url': [
{hostSuffix: '*', pathPrefix: ''},
{hostSuffix: '*', pathPrefix: ''}
]};
chrome.webNavigation.onDOMContentLoaded.addListener(function(tab){
if (toggle)
chrome.tabs.executeScript(tab.id,{code:"alert('loaded')"});
},filter);
I've also tried to set it in the manifest
{
"name": "Tool",
"version": "0.0.1",
"manifest_version": 2,
"description": "Te",
"homepage_url": "",
"icons": {
"16": "icons/logo.png",
"48": "icons/logo.png",
"128": "icons/logo.png"
},
"default_locale": "en",
"background": {
"page": "src/bg/background.html",
"persistent": true
},
"browser_action": {
"default_icon": "icons/logo.png",
"default_title": "browser action demo"
},
"permissions": [
"<all_urls>"
],
"content_scripts": [
{
"run_at": "document_end",
"matches": [
"https://www.google.ca/*"
],
"css": [
"src/inject/inject.css"
]
},
{
"run_at": "document_end",
"matches": [
"https://www.google.ca/*"
],
"js": [
"src/inject/inject.js"
]
}
]
}
and in my inject.js
chrome.extension.sendMessage({}, function(response) {
var readyStateCheckInterval = setInterval(function() {
if (document.readyState === "complete") {
clearInterval(readyStateCheckInterval);
// ----------------------------------------------------------
// This part of the script triggers when page is done loading
console.log("Hello. This message was sent from scripts/inject.js");
// ----------------------------------------------------------
}
}, 10);
});
window.addEventListener ("load", myMain, false);
function myMain (evt) {
console.log('aaann');
var jsInitChecktimer = setInterval (checkForJS_Finish, 111);
function checkForJS_Finish () {
if ( typeof SOME_GLOBAL_VAR != "undefined"
|| document.querySelector ("SOME_INDICATOR_NODE_css_SELECTOR")
) {
clearInterval (jsInitChecktimer);
// DO YOUR STUFF HERE.
console.log('hi');
}
}
}
In your manifest file, you have duplicate content scripts, one with CSS and one with JS. It should look like this:
"content_scripts": [
{
"run_at": "document_end",
"matches": [
"https://www.google.ca/*"
],
"js": [
"src/inject/inject.js"
],
"css": [
"src/inject/inject.css"
]
}
]
Also, if you want it to match other urls, you will need to add them specifically, or use
"matches": ["<all_urls>"]
As for your proposed background script, that is essentially re-inventing the concept of content scripts, and it may not be in your best interest. I suggest sticking with the content script route.
