如何使用 AJAX 实现转盘抽奖功能并将结果传递给 PHP 服务器？

$(function() {
    var $rotaryarrow = $('#rotaryarrow');
    var $result = $('#result');
    var $resulttxt = $('#resulttxt');
    var $resultbtn = $('#resultbtn');

    $rotaryarrow.click(function() {
        var data = [0, 1, 2, 3, 4, 5, 6, 7];
        data = data[math.floor(math.random()*data.length)];

        $.ajax({
            url: 'lottery.php',
            type: 'post',
            data: {
                data: data
            },
            success: function(response) {
                var result = parseint(response);
                rotatefunc(result);
            }
        });
    });

    var rotatefunc = function(awards) {  
        $rotaryarrow.stoprotate();
        $rotaryarrow.rotate({
            angle: 0,
            duration: 5000,
            animateto: awards * 45 + 1440,  
            callback: function() {
                $resulttxt.text(awards);
                $result.show();
            }
        });
    };

    $resultbtn.click(function() {
        $result.hide();
    });
});

<?php

if (isset($_POST['data'])) {
    $data = $_POST['data'];
    
    // 执行抽奖逻辑，并返回获奖结果
    $result = rand(1, 7);
}

echo $result;
?>
