Question

Javascript: how to create an event listener in a Window.Blur () event?

Answer 1

window.onblur = function() {
   //say goodbye
};

Consistent with quirksmode onfocus and onbluravailable windowin most browsers.

Answer 2

It is better to use addEventListenerinstead of a property, so you can set several handlers, and no one (including you) can accidentally disable your handler by overwriting the property onblur.

window.addEventListener('blur', function() {
   console.log('blur');
});

Answer 3

Try:

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