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",

"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 am developing a chrome extension. I want to redirect to a custom html page when new tab is created.
This is process.js file.
chrome.tabs.onCreated.addListener(function() {
alert("hello");
window.open('https://ucsc.cmb.ac.lk/', '_self', false);
});
This is manifest.json file.
{
"manifest_version": 2,
"name": "xxx",
"version": "1.0",
"description": "xxx",
"icons": {
"128": "icon128.png",
"48": "icon48.png",
"16": "icon16.png"
},
"browser_action": {
"default_icon": "icon16.png",
"default_popup": "popup.html"
},
"background": {
"scripts": ["process.js"],
"presistent": true
},
"permissions": [
"storage",
"notifications",
"contextMenus",
"tabs",
"activeTab",
"http://*/",
"https://*/"
]
}
alert is working. but it is not loading the page.
You are probably looking for Override Pages.
Add this code to your manifest file:
"chrome_url_overrides" : {
"pageToOverride": "myPage.html"
},
You can try this:
window.open('https://ucsc.cmb.ac.lk/', '_blank', false);
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.

}
background.js
chrome.webNavigation.onCompleted.addListener(function(details) {
if(details.frameId === 0) {
chrome.tabs.executeScript(details.tabId, {"file": "content.js"});
}
});
I want that if any of my webpage loads I want to simply display a simple alert on the page.

I have jquery stored locally in my chrome extension folder.
eventPage.js
$("document").ready(function(){
alert("hiii");
console.log("hii");
});
I am new to building Chrome Extension. Any help would be appreciated.
Please remove the useless space in your "matches": ["http://*/* "]field, it doesn't match a valid url.
If possible, remove useless permissions if they are not used.

Okay so I'm a JS noob, and I can admit that. I've been reading up and learning how to make extensions for chrome. So I want to have a content script and browser action, but I can't get it to run for the life of me. It's probably something dumb I'm doing something wrong, but any help is appreciated.

I can't write a comment,
Perhaps a comma is missing here
"default_popup": "popup.html"
}, <-- HERE!!
"content_scripts":
How can I write a simple Chrome Extension content script that will execute JavaScript (for example alert("hello");) on every page load?
So when I navigate to a page or reload a page, the JavaScript should run.
This is my manifest.json file so far:
{
"name": "Highlight some phrases",
"description": "Hightlight some pre defined text from websql database after page loads",
"version": "0.1",
"permissions": [
"tabs","<all_urls>"
],
"browser_action": {
"default_icon": "icon.png",
"default_popup": "popup.html"
},
"content_scripts": [
{
"matches": [
"http://*/*",
"https://*/*"
],
"js": ["content.js"]
}
],
"background": {
"page": "background.html"
},
"manifest_version": 2
}
If all you need is to alert hello on every page load or reload, below is a simple demo:
Manifest.json:
{
"name": "Highlight some phrases",
"description": "Hightlight some pre defined text after page loads",
"version": "0.1",
"permissions": [
"tabs","<all_urls>"
],
"browser_action": {
"default_icon": "icon.png"
},
"content_scripts": [
{
"matches": [
"http://*/*",
"https://*/*"
],
"js": ["content.js"],
"run_at": "document_end" // Pay attention to this line
}
],
"manifest_version": 2
}
and content.js:
// alert("hello");
document.body.style.background = 'yellow';
Yes, that's enough.
And of course, don't forget to add an icon named icon.png at the same directory with these two files, then test it in Google Chrome.
