问题
I'm trying to close the Options page of the extension. I have a Cancel button and I'm using this code:
chrome.tabs.getCurrent(null, function(tab) {
chrome.tabs.remove(tab.id, function() {});
});
When I'm trying to use it, it always gives this error:
Uncaught TypeError: Cannot call method 'getCurrent' of undefined
What's wrong with the code?
回答1:
It works for me with one little fix:
chrome.tabs.getCurrent(function(tab) {
chrome.tabs.remove(tab.id, function() { });
});
Just make sure you're really running this code in options page of your extension and not just some HTML page, because chrome.tabs API is available only for extensions.
回答2:
Most likely you're running your code from a content script, where chrome.tabs is undefined. If this is the case, you can instead send a message to the background page and have the background page (which has access to chrome.tabs) make the call.
Note that from a background page, you would use chrome.tabs.getSelected since getCurrent will return undefined.
回答3:
In the options page, you can just do:
window.close()
If you wanted to use chrome.tabs.getCurrent, do you have tabs defined in the permissions section within the manifest?
回答4:
I have time to continue my extension after a very long time. I checked the documentation again. So it was a inline script, that I had probably blocked with Content Security Policy in the manifest, because I hadn't read the documentation precisely.
Now Chrome blocks inline scripts by default, so I'll have to fix it anyway.
