How to cancel all other ajax requests?

I have a SPA website.

When I send request A, I find I clicked wrong link. So I click and send request B before complete request A. So I want to abort request A and all other requests. I tried XMLHttpRequest.abort(); but it is only abort request B.

Simple Source Code :

function link(){
const request=new XMLHttpRequest();
request.open('GET','//example.com/',true);
request.send();
request.onload=()=>{
console.log('Loaded');
}
}

Full Source Code :

link(to){
    const requeset=new XMLHttpRequest();
    request.open('GET','/api/window.location,true);
    request.send();
    request.onload=function(){
    console.log('hello!');
    }
}

You can keep a reference to the previous request something like...

var lastRequest = null;

// Loop through all action buttons
document.querySelectorAll('button.action').forEach(button => {

    // Attach a click event listener
  button.addEventListener('click', event => {
    event.preventDefault();

        // If there was a previous request, kill it.
    if (lastRequest) {
      lastRequest.abort();
      lastRequest = null;
    }

        // Now make the new request and store the reference.
    lastRequest = new XMLHttpRequest();
    lastRequest.open('GET', 'https://reqres.in/api/users?delay=3');
    lastRequest.onload = () => {
      lastRequest = null; // We reset the last request reference on load.
    };
    lastRequest.send();
  });
})

<button class="action">Action 1</button>
<button class="action">Action 2</button>

UPDATE

function link(to) {

    // If there was a previous request, kill it.
    if (window._myLastLinkRequest) {
        window._myLastLinkRequest.abort();
        window._myLastLinkRequest = null;
    }


    const request = new XMLHttpRequest();
    
    request.open('GET','/api/' + window.location, true);
    request.onload = function() {
        console.log('hello!');
        window._myLastLinkRequest = null; // We reset the last request reference on load.
    };
    request.send();

    // Now store the reference to the new request.
    window._myLastLinkRequest = request;
}
