Javacript can not close page in recent version chrome, because it’s not safe. But we can close it with this extension installed.
warning: This extension can only work in http(s)://localhost or 127.0.0.1, to show some local demo.
function closeWindow () {
var event = new Event(‘closeTabMessage’);
document.body.dispatchEvent(event);
};
Run this function in javascript, you can close chrome tab now.
