The Google Chrome Extensions API does not provide the ability to directly listen to the entire browser close event. However, you can listen to the close event of individual tabs or windows. Here are some possible alternatives:
1. Listen for window closing events
You can use chrome.windows.onRemovedthe API to listen for window close events.
chrome.windows.onRemoved.addListener(function(windowId) {
// 执行某些操作
});
This way you can think the browser has been closed when the last window is closed.
2. Listen to the tab close event
Use chrome.tabs.onRemovedthe API to listen for tab close events.
chrome.tabs.onRemoved.addListener(function(tabId, removeInfo) {
// 执行某些操作
});
3. Usechrome.runtime.onSuspend
This event is fired just before the extension is uninstalled, which usually occurs when the browser is closed.
chrome.runtime.onSuspend.addListener(function() {
// 执行清理操作
});
4. Use Background Script
If your extension uses a persistent background script, the script will stop running when the browser is closed. You can set some cleanup operations in this script.
It's important to note that none of these methods are 100% accurate for browser closure detection, but they should be sufficient in most cases.
