It's better to use addEventListenerinstead of a property, this way you can set multiple handlers and nobody (including yourself) will accidentally disable your handler by overwriting the onblurproperty.
最好使用addEventListener而不是属性，这样您就可以设置多个处理程序，并且没有人（包括您自己）会通过覆盖onblur属性来意外禁用您的处理程序。
window.addEventListener('blur', function() {
console.log('blur');
});

尝试：
window.onBlur = function(e) {
// Code here.
}
