I am trying to get a keyboard shortcut to work and at this point I am just testing to see that pressing the shortcut works. So currently what I have it do is send a message to the background page that it is working but the key press never registers. I was wondering how to address this issue.
manifest.json
{
"manifest_version": 2,
"name": "My Cool Extension",
"version": "0.3.1.5",
"description":"User can enter in wepage and press button to open webpage in new tab.",
"background": {
"scripts": ["background.js"]
},
"content_scripts": [
{
"matches": [
"<all_urls>"
],
"js": ["jquery-2.1.4.min.js", "content.js"]
}
],
"browser_action": {
"default_icon": "arrow.png",
"default_popup":"popup.html"
},
"permissions": [
"tabs",
"storage"
],
"icons":{
"128":"arrow.png"
},
"commands": {
"openSavedTab": {
"suggested_key": {
"default": "Ctrl+Shift+Y",
"mac": "Command+Shift+Y"
},
"description": "Opens saved tab"
}
}
}
tab_shortcuts.js
chrome.commands.onCommand.addListener(function(command) {
chrome.tabs.update({}, function(tab) {
if (command == 'toggle-pin-tab')
chrome.extension.getBackgroundPage().console.log("Shortcut is functional");
alert("working");
});
});
Thank you wOxxOm for your help. You were right when you said the issue was with a conflicting extension with the same hotkey assigned. Once I disabled the extension my extension worked properly.

I am currently developing a chrome extension. Only, here I am confronted with a problem:
I would like my extension to detect when the user performs a keyboard shortcut and that triggers a JS function. For that, my manifest.json file looks like this:
{
"manifest_version": 3,
"name": "name",
"version": "1.0.0",
"description": "description.",
"icons":{
"16": "img/logo16.png",
"48": "img/logo48.png",
"128": "img/logo128.png"
},
"permissions": [
"storage",
"activeTab",
"scripting"
],
"background": {
"service_worker": "js/background.js"
},
"commands": {
"Restart App": {
"suggested_key": {
"default": "Ctrl+Shift+6",
"mac": "Command+Shift+6"
},
"description": "Restart my app (Debugging)"
}
}
}
My background.js file located in the js folder, contains this:
chrome.commands.onCommand.addListener(function (command)
{
if (command == "Restart App")
{
chrome.runtime.reload();
};
alert('app restart success !');
});
Only, when I launch the extension and execute the keyboard shortcut, nothing happens, no error is reported.
Would you have any ideas, thank you in advance.
I'm starting to create a simple chrome extension and one of the features I need is a notification system, so I'm using onesignal, in my script. I wish the user when installing the chrome extension to subscribe automaticlly, but it is not loading the object of onesignal which I can't figure out why. I'm saying this because no subscriptions is showing up after I install it.
My code:
manifest.json
{
"name": "My title",
"version": "0.0.1",
"manifest_version": 2,
"description": "some description",
"background": {
"scripts": [
"background.js","OneSignal.js"
],
"persistent": false
},
"browser_action": {
"default_title": "my extension"
},
"permissions": [
"https://*/*",
"http://*/*",
"tabs",
"gcm",
"notifications",
"storage",
"identity"
]
}
background.js:
OneSignal.init({appId: "dasdasd-b228-437d-bb8f-43asdasdb3", googleProjectNumber: "99999999"});
Am I missing something?
The problem is in the scripts order:
Solution:
...
background": {
"scripts": [
"OneSignal.js","background.js"
],
..
Even after searching a lot of topics in stack overflow, nothing helped me to fix this error...
I'm trying to create an extension, and for now there are simple codes in it, but unfortunately, the console is not logging 'Hello, world!' from the content_scripts file.
manifest.json
{
"manifest_version": 2,
"name": "Example",
"shortname": "exmpl",
"description": "__MSG_appDesc__",
"version": "0.0.1",
"default_locale": "en",
"author": "Mateus Akino",
"icons": {
"16": "i16x.png",
"48": "i48x.png",
"128": "i128x.png"
},
"homepage_url": "http://example.com/",
"browser_action": {
"default_icon": "i32x.png",
"default_popup": "popup.html"
},
"update_url": "http://example.com/update.xml",
"chrome_url_overrides": {
"newtab": "newtab.html"
},
"content_scripts": [{
"matches": ["*://*.youtube.com/*"],
"js": ["execute.js"],
"run_at": "document_end"
}],
"background": {
"scripts": ["background.js"]
},
"permissions": [
"activeTab", "tabs", "i18n", "management", "webNavigation", "<all_urls>"
]
}
execute.js
console.log("Hello, world!");
background.js
chrome.webNavigation.onHistoryStateUpdated.addListener(function (details) {
chrome.tabs.executeScript(null, {
file: "execute.js"
});
});
I fixed the problem, so I'm posting it here if someone else has the same issue.
Looks like the code was fine, the problem was the way I was loading the extension...
As I'm using 'Load unpacked extension', my manifest.json wasn't updating just by disabling and enabling it (neither by using Refresh extensions now).
So I removed the extension, loaded it again and it's working normally now.
I'm trying to make a Google chrome extension that injects a script upon clicking the extension icon. However, i want the same script to be injected whenever I load/go to another page, without having to click on the extension icon again.
background.js
chrome.browserAction.onClicked.addListener(function (tab) {
if (tab.url.startsWith("https://")){
chrome.tabs.executeScript(tab.id, {
"file": "js/contentscript.js"
}, function () {
console.log("Script Executed .. "); // Notification on Completion
});
}
else{
alert('Error');
}
});
manifest.json i want to execute the script on browserAction so adding the script on content_scripts is not an option i would like to pursue
"permissions": ["tabs", "windows", "notifications", "activeTab"],
"version": "2.0",
"browser_action":
{
"name": "Click to activate extension",
"default_icon": "images/icon.png",
},
"background":
{
"scripts":["js/background.js"]
},
"icons":
{
"16": "images/icon16.png",
"48": "images/icon48.png",
"128": "images/icon128.png"
},
"content_scripts":
[{
"js": ["js/jquery-2.1.4.min.js"],
"matches": [ "https://*/*" ],
"run_at": "document_end"
}]
contenscript.js - only a sample script, but gets my point across
alert("here");
setTimeout(function(){window.open("www.google.com");});
P.S. This is my first time asking a question in stackoverflow, please be gentle with me. :D
You could listen to webNavigation.onCompleted event, which fires when a document, including the resources it refers to, is completely loaded and initialized.
Compared with tabs.onUpdated event, you could use event filters to restrict your event notifications. For this part, you could check my answer in this post Running an extension in background on page load/refresh for more details.
manifest.json
{
"name": "36735306",
"version": "1.0",
"description": "Your description here",
"manifest_version": 2,
"background": {
"scripts": ["background.js"]
},
"web_accessible_resources": ["content.js"],
"permissions": [
"webNavigation",
"<all_urls>"
]
}
background.js
chrome.webNavigation.onCompleted.addListener(function(details) {
if(details.frameId === 0) {
chrome.tabs.executeScript(details.tabId, {"file": "content.js"});
}
});
I'm new to chrome extensions and cannot seem to figure out how the background concept works. I am building a counter extension that keeps counting even when the user closes the extension (but not the browser) and wanted to do a simple test to see if I could figure out how to use the background file. Below is my attempt to create a function that activates everytime a user clicks on a tab (outside of my extension) and when they click on 5 tabs, the alert hits. I cannot figure out why this doesn't work.
background.js:
var counter = 0;
chrome.browserAction.onClicked.addListener(function(tab){
counter++;
if (counter == 5) {
alert("Hi");
}
});
manifest.json:
{
"name": "Hello World!",
"description": "My first packaged app.",
"version": "0.1",
"permissions": ["tabs", "http://*/*"],
"manifest_version":2,
"content_scripts": [ {
"js": [ "jquery-1.9.1.js", "myscript.js" ],
"matches": [ "http://*/*", "https://*/*"]
}],
"background": {
"scripts": [
"background.js"
]
},
"browser_action": {
"default_title": "10,000 Hours",
"default_icon": "icon16.png",
"default_popup": "index.html"
},
"icons": {
"16": "icon16.png",
"48": "icon48.png",
"128": "icon128.png"
}
}
It is working for me with following code.
manifest.json
{
"name": "Popping Alert",
"description": "http://stackoverflow.com/questions/15194198/background-js-not-working-chrome-extension",
"background": {
"scripts": [
"background.js"
]
},
"version": "1",
"manifest_version": 2,
"browser_action": {
"default_title": "Click Me"
}
}
background.js
var counter = 0;
chrome.browserAction.onClicked.addListener(function (tab) {
counter++;
if (counter == 5) {
alert("Hey !!! You have clicked five times");
}
});
Can you share your related code or put your problem statement clearly if this does not work?
