I've already read the documentation from
Google on 'message passing' a few times and have probably looked at over 10 other questions with the same problem and already tried quiet a few variations of most of their "solutions" and of what I have below... This is black magic, right? Either way, here it goes.
Manifest File:
{
"manifest_version" : 2,
"name" : "Message Test",
"version" : "1.0",
"browser_action": {
"default_popup": "popup.html"
},
"background": {
"
scripts": ["background.js"]
},
"content_scripts": [
{
"matches" : ["<all_urls>"],
"js": ["message-test.js"]
}
]
}
I'm aware extensions aren't suppose to use inline JS, but I'm leaving this in so the original question can be left as it was since I still can't get the message to send from the background page, When I switch from the popup to the background, I removed the appropriate lines from the manifest.json
popup.html file:
<html>
<head>
<script>
chrome.tabs.query({active: true, currentWindow: true}, function(tabs) {
chrome.tabs.sendMessage(tabs[0].id, {greeting: "hello", theMessage: "Why isn\'t this working?"}, function(response) {
console.log(response.farewell);
});
});
</script>
</head>
<body>
</body>
</html>
OR
background.js file:
chrome.tabs.query({active: true, currentWindow: true}, function(tabs) {
chrome.tabs.sendMessage(tabs[0].id, {greeting: "hello", theMessage: "Why isn\'t this working?"}, function(response) {
console.log(response.farewell);
});
});
message-test.js file:
var Mymessage;
chrome.runtime.onMessage.addListener(function(message, sender, sendResponse) {
if (message.greeting == "hello"){
Mymessage = message.theMessage;
alert(Mymessage);
}
else{
sendResponse({});
}
});
No alert(Mymessage) goes off.
I'm also trying to execute this after pressing a button from a popup and having a window at a specified url, but that's a later issue. The other files can be found here except with the background.js content wrapped in an addEventListener("click"....:
