Unable to send message from backgrund.js to content_script.js.

kurohoan commented 4 years ago

Although the alert of "content_script.js" is displayed, "chrome.runtime.onMessage.addListener()" does not start and I cannot receive the message from "background.js". Is something wrong?

background.js

chrome.tabs.query({
    active: true,
    currentWindow: true
}, function (t) {
    chrome.tabs.sendMessage(t[0].id, {action: 'entry'});
});

content_script.js

chrome.runtime.onMessage.addListener( (mess, sender, sendResponse) =>  {
    console.log('Get message!');
});
alert('OK');
