Async detect switch tab
Hi everyone!I want to detect switch tab.
I add listener on event "on blur" in background.js.
opera.extension.tabs.onblur = onBlur;
function onBlur() {
sendMessage("onblur");
}
I process it message in injected.js.
opera.extension.addEventListener('message', onMessage, false);
var onMessage = function(event) {
var message = event.data;
if(message.topic == 'onblur'){
//todo query to my plugin
}
}
Query to my plugin send after I comeback to previous tab.
Why?
Please thank me)
