send ajax request without waiting answer

Question

I want to make an ajax request to send some information and immediately after sending it (doesnt matter if I get an error/success) make a redirection (without waiting server response)

I was wondering if I do something like

$.ajax({
url:_myurl_,
timeout:500,
success:function(){document.location= _redirectUrl_},
error: function(){document.location= _redirectUrl_}
})

will work fine? Does adding a timeout wont cancel my request?

Answer 1

AJAX by definition is asynchronous. Just add location redirect code AFTER the ajax block, not Inside AJAX.

function dummyAjax(){
    $.ajax({
      //do something
      success:function(res){
          console.log(res);//chrome try preserve log you'll see this response even after redirection
      }
    });
    window.location.replace('https://google.com');//this would fire without waiting for ajax response
}

async: false in async Mode process are not wait to complete other process

Answer 3

Just do not implement any success handler.

So you could do ...

$.ajax({
    type: "post",
    url: "/log-message"
});

And since it is asynchronous, it will be non blocking and any code following this statement will be executing without waiting from the response from the server.
