In short, I want that when you press my extension button from the context menu, the content script (contect-script) will be added to the web page temporarily. I tried to use sendMessage() but it just didn’t work.
Any help will be appreciated:)
//This is the servise worker (eventPage)
chrome.runtime.onInstalled.addListener(() => {
chrome.contextMenus.create({
id: 'select',
title: 'select',
type: 'normal',
contexts: ['all']
});
})
chrome.contextMenus.onClicked.addListener(function (clickDate) {
if (clickDate.menuItemId == 'select') {
//send massege to make content-script start operate
chrome.runtime.sendMessage('start');
}
});
-------------------------------------------------------------------------
//lets say that this is the content-script
chrome.runtime.onMessage.addListener(function(response,sender,sendResponse){
if(response == 'start'){
// js code that is inserted into the site
}
});{
