Can someone help me, I'm building my first chrome extension and it's a popup with a button that's supposed to do something on click (just using alert now), but somehow whatever in my js file doesn't seem to be working. Styles also seem not to load.
manifest:
{
"name": "Toolbar",
"manifest_version": 2,
"version": "1.0.2",
"description": "Toolbar",
"background": {
"scripts": ["background.js"]
},
"browser_action": {
"default_icon": "icon.png",
"default_title": "None",
"default_popup": "popup.html"
},
"permissions": [
"tabs", "http://*/", "https://*/"
]
}
popup.html:
<html>
<head>
<link rel="stylesheet" type="text/css" href="styles.css">
<script src="popup.js"></script>
</head>
<body>
<div>
<button type="button" id="closeButton"> x<button/>
</div>
</body>
</html>
popup.js:
function closePopup ()
{
//window.close();
alert("hello");
}
document.addEventListener('DOMContentLoaded', function() {
document.getElementById('closeButton').on("click", function (){
closePopup();
}
});
});
<html>
<head>
<link rel="stylesheet" type="text/css" href="styles.css">
<!--<script src="popup.js"></script> delete this-->
</head>
<body>
<div>
<button type="button" id="closeButton"> x<button/>
</div>
<!--add this--><script src="popup.js"></script>
</body>
</html>
place the script after the object, where the eventlistener is placed on. I had the same problem and that fixed it
You've got to put the <script src="popup.js"></script> in the <body> instead of <head> tag. That worked for me.

Using Chrome Manifest 3, how can I write a chrome extension that can query the contents of the active tab? I've looked at the API for tabs as well as the scripting API, but I can't seem to find the right way to query the DOM contents of the active tab.
When the button in my popup HTML "Save Content" is clicked, I am expecting my function changeBackgroundColor to execute, allowing me access to the DOM of the active tab. However, the function never executes and moreover I do not know whether or not I will be able to query the DOM of the active tab while my code executes within changeBackgroundColor
Does anyone see what I am doing wrong? Here are the relevant files below:
Here is my popup.html:
<html>
<head>
<link rel="stylesheet" type="text/css" href="normalize.css">
<link rel="stylesheet" type="text/css" href="popup.css">
</head>
<body>
<main id="app---KZzQjJcI2kdN0Qnn7X7AgyoO8W6VBwuOPIcyztpKBaU">
<div class="app__hero-section--KZzQjJcI2kdN0Qnn7X7AgyoO8W6VBwuOPIcyztpKBaUp">

<button id="get-images--KZzQjJcI2kdN0Qnn7X7AgyoO8W6VBwuOPIcyztpKBaU" class="app__get-images-button--KZzQjJcI2kdN0Qnn7X7AgyoO8W6VBwuOPIcyztpKBaUp">Get Images</button>
</div>
<div class="app_images-hero--KZzQjJcI2kdN0Qnn7X7AgyoO8W6VBwuOPIcyztpKBaUp">

</div>
<div class="app_images-section--KZzQjJcI2kdN0Qnn7X7AgyoO8W6VBwuOPIcyztpKBaUp">
</div>
<button class="app__import-images-button--KZzQjJcI2kdN0Qnn7X7AgyoO8W6VBwuOPIcyztpKBaUp">Import Images</button>
<script type="text/javascript" src="jquery-3.5.0.min.js"></script>
<script type="text/javascript" src="popup.js"></script>
</main>
</body>
</html>
This is the JS of the popup:
function changeBackgroundColor() {
console.log('here!!')
}
function findOrCreateContent() {
chrome.tabs.query({active: true, currentWindow: true}, (tabs) => {
chrome.scripting.executeScript({
target: {tabId: tabs[0].id},
func: changeBackgroundColor
})
});
}
document.addEventListener("DOMContentLoaded", function(event) {
document.querySelector('#save-content--KZzQjJcI2kdN0Qnn7X7AgyoO8W6VBwuOPIcyztpKBaU').addEventListener('click', findOrCreateContent);
});
This is my manifest json:
{
"manifest_version": 3,
"icons": {
"16": "thing-icon.png",
"128": "thing-icon.png"
},
"name": "Content Saver",
"description": "Save content in the cloud",

"action": {
"default_title": "Content Saver",
"default_popup": "popup.html"
},
"permissions": [
"scripting"
],
"host_permissions": [
"http://*/*",
"https://*/*"
]
}
I want the current tab url to be display in the pop up after clicking the extension. I have a popup html and popup.js. For testing purpose, I been trying to alert the tab url instead of replacing the html element.
Manifest.json
{
"manifest_version": 2,
"name": "first extension",
"version": "1.0",
"browser_action": {
"default_icon": "icon.png",

popup.js
chrome.tabs.getCurrent(function(tab){
alert(tab.url);
}
);
You may want to follow the suggested workaround in this link. Try this query chrome.tabs.query(object queryInfo, function callback) which will get all tabs that have the specified properties, or all tabs if no properties are specified.
chrome.tabs.query({currentWindow: true, active: true}, function(tabs){
console.log(tabs[0].url);
});

You can use jquery autocomplete plugin and it works like a charm.

});

The example above binds a static array to the control, instead you can also get dynamic array in document.ready() using ajax call.
I'm currently developing an overlay for Google Chrome (A toolbar if you prefer), and i have some issues with and i can't understand the reason why.
So, basically i've created an extension with this manifest.json :
{
"background_page" : "background.html",
"browser_action" :
{
"default_icon" : "images/Extension.png"
},
"content_scripts":
[ {
"all_frames": true,
"css": ["css/overlay.css"],
"js": ["js/overlay.js"],
"matches": ["http://*/*"],
"run_at": "document_start"
} ],
"permissions" : ["tabs", "unlimitedStorage", "http://*/*"],
"name" : "MyOverlay",
"version" : "1.1",
"description" : "Sindar Overlay"
}
The concept is that my background.html page will call the jquery.js and overlay.js. Then on the initialization of overlay.js it will call the html page (overlay.html) by using
<iframe id="YourToolbarFrame" src="'+toolbarURL+'">
The problem is that when i'm trying to start the extension everything seem to be good, no compilation problem but i don't see my overlay. And when i'm just opening the html page all is ok, i see it. So i'm asking myself if the problem dont come from the contentscript or from the permissions but i dont know where it could come from...
Thanks in advance.

Currently you include overlay.js as a content script to all pages plus include it into a background page for some reason. You don't need a background page for this task. If you are doing this just to inject jquery the solution would be to download jquery.js and put it into your extension folder, then automatically inject it in the manifest.json:
//"background_page" : "background.html", - this is not needed
"content_scripts":
[ {
"all_frames": true,
"css": ["css/overlay.css"],
"js": ["js/jquery.js", "js/overlay.js"], //jquery included as well
"matches": ["http://*/*"],
"run_at": "document_start"
} ],
(besides a background page doesn't have visible body, so you inject your frame to an invisible page right now)
