I want to know how to detect if a button with a certain id is clicked on a webpage with my chrome extension. With my code I have an error saying that my element is undefined. Here is my manifest :
{
"manifest_version": 2,
"name": "app",
"description": "my app",
"version": "1.0",
"browser_action": {
"default_icon": "icon.png",
"default_popup": "popup.html",
"default_title": "Changer le background"
},
"permissions": [
"activeTab",
"storage"
]
}
And my popup.js file :
document.addEventListener('DOMContentLoaded', () => {
getCurrentTabUrl((url) => {
document.getElementById('mybutton').addEventListener('click', function() {
var script = "console.log('clicked');";
chrome.tabs.executeScript({code: script});
});
});
});
your popup.js will not load until the user himself will click on the extension's icon... i think you should change your approach and use a content-script like this:
document.getElementById('mybutton').addEventListener('click', function() { console.log('clicked'); });
you'll need to update your manifest.json for using a content script, something like that:
"content_scripts": [ { "matches": ["the url of a page for the script", "the url of another page"], "js": ["your_script.js"] } ],
