sending message to chrome extension from a web page

Question

I want to send message from the console of the random web page to my chrome extension. chrome.extension.sendMessage doesn\'t seem to work.

Answer 1

In addition to @hewigovens , I don't have enough points to comment... I'm explaining @renatoargh and @sbichenko If sending message from a default web page -

1) the webpage needs to be quoted in the manifest. e.g.:

"externally_connectable": {
  "matches": ["http://abcde/abcde/main.aspx*"]
}

2) the background.js (background page) excepts the call with onMessageExternal e.g. (calling an extension):

var host_name = "com.my_chrome_extension.com";
 chrome.runtime.onMessageExternal.addListener(function(message, sender, sendResponse) {
    chrome.runtime.sendNativeMessage(host_name, {"run":message});
    sendResponse({"success": "success"});
    return true;
});
