I got the following files in my Chrome extension project.

|--popup.html
|--manifest.json
|--images
|--get_started16.png

No errors loading the files (loading the extension as unpacked files). When the extension icon is clicked it opens the default menu with
Remove from home
Hide in chrome menu
Manage extensions
Inspect popup
etc...not the popup.html, However the content script and background script logging hello to their consoles. Clicking on Inspect popup does nothing.
I'm using (on Arch linux),
Chrome: Version 75.0.3770.100 (Official Build) (64-bit)
Chromium: Version 75.0.3770.100 (Official Build) Arch Linux (64-bit)
Popup is not working in both browsers. I tried changing file permissions as below
chmod -R 777 dist/
I loaded getting started tutorial project files. The popup in that is working fine. What as I missing here?

I am trying to make a form filler chrome extension, and I am getting no errors when it interact with the extension, but when I click the button on the chrome extension fields on the job application form are still not getting filled in.

I'm trying to create a chrome extension, so I'm doing tutorials to learn and reading a bunch, but I'm struggling. I'm doing this tutorial. But long-term, from the extension I need users to be able to login to their account, then as they're browsing, send the url that they're at to their account.
popup.html
<!doctype html>
<html>
<head>
<title>Add a Snippet</title>
<script src="popup.js"></script>
<link rel="stylesheet" type="text/css" href="popup.css">
</head>
<body>
<h1>Add a Snippet</h1>
<form id="form">
<textarea id="code"></textarea>
<button type="submit" id="checkPage">Add Snippet</button>
</form>
</body>
</html>
popup.js
What I REALLY don't understand is that according to the console.log lines that I have in there and the error, it's loading the DOMContent, and it doesn't have any problem with finding the form by the id (let f = document.getElementById('form');). But it bombs when I try to attach an event listener?
document.addEventListener('DOMContentLoaded', function() {
console.log('the domcontentloaded');
let f = document.getElementById('form');
f.addEventListener('submit', function(e){
console.log('the form was submitted');
e.preventDefault();
})
}, false);
manifest.json
{
"name": "My Awesome Plugin",
"description": "This extension will be awesome",
"version": "1.0",
"browser_action": {
"default_icon": "icon.png",
"default_popup": "popup.html",
"default_title": "This is Awesome"
},
"background": {
"scripts": ["jquery-2.2.3.min.js", "background.js","popup.js"],
"persistent": false
},

"matches": [
"<all_urls>"
],
"js": ["login.js"]
}
],
"manifest_version": 2
}
login.js
console.log('login.js is ready to party');
When I load, I get this in the background inspector (or whatever it's called). So it's not finding the form.
So I looked at the elements, and I'm confused because it's not showing the form or the textarea. But when I click on the chrome extension icon, it's there.
1/Remove popup.js from "background/scripts" section of your manifest.
2/Add popup.js as a script reference in your popup.html file.
This way, popup.js will operate in the context of the popup.html DOM.
I'm developing a chrome extension and I want to display in the popup (when a user click extension icon) a page that has an url of localhost, in this page I will check if a user is logged in my site and depend on status I will display content in the page.
So I tried these:
First:
create a popup.html (that doesn't contain the iframe)
in popup.js create an iframe and give it an src, width, height. than append it to the body.
Second:
in the popup.html add the iframe with the src of localhost.
in popup.js create an iframe and give it an src, width, height. than append it to the body.
Neither the first nor the second works. and I get this:
But when I use a normal site in src, like http://bing.com it works and show the page of bing.com
This is a MVCE example that I developed:
The HTML files are:
index.html is the file that is served through the web server
<html>
<body>
<h1>Hello World!</h1>
</body>
</html>
popup.html is the extension popup content
<html>
<body>
<div id="container">
</div>
<script src="content.js"></script>
</body>
</html>
with the manifest for the extension:
manifest.json
{
"manifest_version": 2,
"name": "Test Popup",
"version": "0.1",
"browser_action": {
"default_title": "Popup Test",
"default_popup": "popup.html"
},
"permissions": [
"tabs", "<all_urls>"
],
"content_scripts": [
{
"matches": [
"http://*/*"
],
"js": [
"content.js"
]
}
]
}
All you need is a server for the external file to include, I used ruby:
serve.rb
require 'webrick'
s = WEBrick::HTTPServer.new(:Port => 8888, :DocumentRoot => Dir.pwd).start
All the magic happens in the content javascript:
content.js
function addiframe() {
div = document.getElementById("container");
var frame = document.createElement('iframe');
frame.setAttribute('width', '500px');
frame.setAttribute('height', '500px');
frame.setAttribute('frameborder', '0');
frame.setAttribute('id', 'inject');
frame.setAttribute('src', 'http://localhost:8888');
div.appendChild(frame);
};
addiframe();
and this is an image that shows the result:
I am making a chrome extension. I need to run a js script when the popup opens. How can I do that from background.js?
I am almost sure that this has already been asked and answered here, but it was easier to write it again than to find the existing question. You need to use message passing.
manifest.json
{
"manifest_version": 2,
"name": "My extension",
"description": "Start action in background from popup.",
"version": "1.0",
"browser_action": {
"default_title": "My extension",
"default_popup": "popup.html"
},
"background": {
"scripts": ["event.js"]
}
}
popup.html
<!DOCTYPE html>
<html>
<head>
<script src="popup.js"></script>
</head>
<body>
<p>Background page has been notified</p>
</body>
</html>
popup.js
chrome.runtime.sendMessage({text: "popup opened"});
event.js
chrome.runtime.onMessage.addListener(function(message,sender,sendResponse){
if (message.text == "popup opened") {
console.log ("Popup says it was opened.");
// Run your script from here
}
});
I want to display a Amazon Affiliate Widget Code in the popup section of a chrome extension.
The manifest.json looks like this(Copied as it is from Google Repository):
{
"manifest_version": 2,
"name": "Getting started example",
"description": "This extension shows a Google Image search result for the current page",
"version": "1.0",
"browser_action": {
"default_icon": "icon.png",
"default_popup": "popup.html"
},
"permissions": [
"activeTab",
"https://ajax.googleapis.com/"
]
}
The backgroung.js is blank.
The Popup.html looks like this:
<html>
<head>
<title>
Amazon
</title>
</head>
<body>
<h1>Amazon Search</h1>
<script charset="utf-8" type="text/javascript">
amzn_assoc_ad_type = "responsive_search_widget";

I am new to this extension development and also new to HTML.
Please help me, I want to run the search widget in the popup.
This is what happens when I click on the Extension.

Thanks.
You can't link to external links in the popup.html file. Instead, you should add a separate javascript file to your extension's background and call the widget's script from there.
Your manifest will look something like this (don't forget to add Content-Security-Policy rules):
{
"manifest_version": 2,
"name": "Getting started example",
"description": "This extension shows a Google Image search result for the current page",
"version": "1.0",
"browser_action": {
"default_icon": "icon.png",
"default_popup": "popup.html"
},
"background" : {
"scripts" : [ "background.js" ],
},
"content_security_policy" : "script-src 'self' 'unsafe-eval' http://z-in.amazon-adsystem.com; object-src 'self'",
"permissions": [
"activeTab",
"https://ajax.googleapis.com/",
"http://z-in.amazon-adsystem.com/"
]
}
Your background.js file can call the script in an iframe:
(function() {
var widget = document.createElement('iframe');
widget.src = "//z-in.amazon-adsystem.com/widgets/q?ServiceVersion=20070822&Operation=GetScript&ID=OneJS&WS=1&MarketPlace=IN";
widget.id = 'widget';
document.body.appendChild(widget);
//assign your widget variables
})();
And your popup.html can just have a script link to your background file:
<script type="text/javascript" src="../background.js"></script>
I haven't tested this, but it's the general gist of how to run external scripts in your extension.
