I'm using the following code (in background.js ) to get the active tab
chrome.tabs.query({active: true, lastFocusedWindow: true}, function(tabs) {
console.log("active tab retrieved : " + tabs[0].id);
});
This works great, except for one case: when this piece of code is inside a messaging listener. For example the next scenario:
In background.js
chrome.runtime.onMessage.addListener(
function(message, sender, sendResponse) {
console.log("message received");
chrome.tabs.query({active: true, lastFocusedWindow: true}, function(tabs) {
console.log("active tab retrieved : " + tabs[0].id);
});
}
);
*in content_script.js*
chrome.runtime.sendMessage({}, function(response) {});
I only got the following in console
message received
and I didn't get the second log in console.
Why is this happening and how to solve it ?
There is an unclosed parenthesis in your code, which raises an exception and aborts execution. Correct it like this:
chrome.runtime.onMessage.addListener(
function(message, sender, sendResponse) {
console.log("message received");
chrome.tabs.query({active: true, lastFocusedWindow: true}, function(tabs) {
console.log("active tab retrieved : " + tabs[0].id);
}); // <-- add `);`
}
);
That said, if you just want to get the tab that sent the message, it is much easier:
sender.tab.id
