I am new to Chrome extensions. I am trying to communicate between the content script and the background.html page. The background.html sends a request, hello, to the content script and the content script should respond back with hello background alert. But it's just not happening. My background.html code is:
function testRequest() {
chrome.tabs.getSelected(null, function(tab) {
chrome.tabs.sendRequest(tab.id, {greeting: hello});
});
}
content.js code:
chrome.extension.onMessage.addListener(
function(request, sender, sendResponse) {
if (request.greeting == hello)
alert(hello background);
}
);
popup.html code:
<!doctype html>
<html>
<head></head>
<body>
<form>
<input type=button value=sendMessage onclick=testRequest() />
</form>
</body>
</html>
manifest.json:
{
browser_action: {
default_icon: icon.png,
popup: popup.html
},
background: {
page: background.html
},
permissions: [
tabs,
http://*/*,
https://*/*,
notifications,
contextMenus
],
content_scripts: [
{
matches: [http://*/*,https://*/*],
js: [content.js]
}
],
name: FirstExtension,
version: 1.0
}
Please help!
