Window.onblur function 在 Chrome 中不工作，但在 Firefox 中工作

Question

This works in Firefox, but not in Chrome:

    window.onblur = () => {
      console.log('blur')
    }

I ran that code in Firefox and it worked, then ran the same code in Chrome, and it doesn't work.

What am I missing?

Answer 1

Try using ES5 instead on ES6 syntax, like so:

 window.onblur = function(){ console.log('blur') }

Answer 2

Doesn't seem to be working for me either.

You can try this instead:

document.addEventListener('visibilitychange', function(e) {
  if (document.visibilityState === 'hidden') {
    console.log('Hidden');
  }
});

Works with Chrome: Version 88.0.4324.150 (Official Build) (x86_64)
