线上运行，可以直接打开：棒球幻数计算器(在线计算器)

作为程序员，没有合适的工具，就得手搓一个，PC端，移动端均可适用。废话不多说，直接上代码。

HTML:

<div class="calculator"><div class="input-group"><label for="totalGames">赛季总场次（G）：</label> <input id="totalGames" min="1" type="number" value="162" placeholder="例如 162"></div><div class="input-group"><label for="teamWins">球队胜场数（W）：</label> <input id="teamWins" min="0" type="number" placeholder="请输入当前胜场数"></div><div class="input-group"><label for="opponentLosses">竞争对手输场数（L<sub>对手</sub>）：</label> <input id="opponentLosses" min="0" type="number" placeholder="请输入竞争对手输场数"></div><button onclick="calculateMagicNumber()">计算幻数</button><div id="result" class="result">幻数：--</div></div>

JS:

function calculateMagicNumber() {
            const totalGames = parseInt(document.getElementById('totalGames').value);
            const teamWins = parseInt(document.getElementById('teamWins').value);
            const opponentLosses = parseInt(document.getElementById('opponentLosses').value);

            const resultElement = document.getElementById('result');

            // 检查输入是否有效
            if (isNaN(totalGames) || isNaN(teamWins) || isNaN(opponentLosses) || 
                totalGames <= 0 || teamWins < 0 || opponentLosses < 0) {
                resultElement.textContent = '请输入有效的数据。';
                return;
            }

            const magicNumber = totalGames + 1 - teamWins - opponentLosses;

            if (magicNumber <= 0) {
                resultElement.textContent = `幻数：${magicNumber}（球队已经锁定目标！）`;
            } else {
                resultElement.textContent = `幻数：${magicNumber}`;
            }
        }

CSS:

.calculator {
    width: 100%;
    background-color: #333;
