Send POST data to PHP without using an HTML form?

Question

Is there anyway to send post data to a php script other than having a form? (Not using GET of course).

I want javascript to reload the page after X seconds and post

Answer 1

You can send an xhr request with the data you want to post before reloading the page.

And reload the page only if the xhr request is finished.

So basically you would want to do a synchronous request.
