Equivalent of Fetch 'no-cors' mode in XHR or Ajax libraries?

问题

Is there a way to write fetch {mode: 'no-cors'} in an existing (and most browsers supported) HTTP request? As an example, I would like to know if it's possible to translate this:

fetch(url, { mode: 'no-cors'})
.then(function (response) {
  console.log(response);
});

Into a XMLHttpRequest or Ajax of some sort. I tried several ways and they behave differently - I just want the opaque response that fetch returns.

Thanks!
