How to access $(this) in $.ajax({ }) block?

Question

I want to access clicked button's methods inside ajax' block. I want to make my first game and I am new at javascript please help!

$(document).on("click",".play",function(e){
            e.preventDefault();
            $(this).text("Confirming..");//clicked button I want to access in ajax scope
            stopint();

            //get players' Ids
            var linkText = $(this).attr("href");
            var link = new URL("http://"+linkText);
            var p1 = link.searchParams.get("player1");
            var p2 = link.searchParams.get("player2");
            console.log(p1+","+p2);

            $.ajax({
                url: "matching_player.php",
                type: "POST",
