Chrome Broadcast for Content Scripts

Question

Is there a way to pass a chrome message to all chrome extension content scripts?

chrome.runtime.sendMessage () accepts tabId as input. However, if there are several tabs launched with the contents of the script, how can I translate all the tabs?

Answer 1

I assume that you were referring chrome.tabs.sendMessageto the tab identifier argument.

There are 2 in the Chrome API sendMessage:

• chrome.runtime.sendMessagewill be broadcast to all pages launched at the beginning chrome-extension://your-extension-id/.

  , ( ), ( ) , .

• chrome.tabs.sendMessage , ( ), , .

, . , :

!

chrome.tabs.query({}, function(tabs) {
  tabs.forEach(function(tab) {
    chrome.tabs.sendMessage(tab.id, message);
  });
});

, :

// Even accepts arrays of patterns!
chrome.tabs.query({url: "*://*.example.com/*"}, function(tabs) {
  tabs.forEach(function(tab) {
    chrome.tabs.sendMessage(tab.id, message);
  });
});
