I am writing a chrome extension - my code below :
content scripts
chrome.runtime.sendMessage('someId', proportion, function () {
console.log('called!');
});
background script
chrome.runtime.onMessage.addListener(function (proportion, sender, callBack) {
chrome.tabs.setZoom(sender.tab.id, proportion, function () {
callBack();
});
});
The callBack should be called after setZoom is done, but it didn't.
If I change background script code like this:
chrome.runtime.onMessage.addListener(function (proportion, sender, callBack) {
chrome.tabs.setZoom(sender.tab.id, proportion, function () {
});
callBack();
});
The callBack has been called, and console output called!.
