就是这个样的粗爆，手搓一个计算器：经期计算器

线上运行，可以直接打开：经期计算器(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"><label for="lastPeriod">上次月经日期：</label> <input id="lastPeriod" type="date" placeholder="选择上次月经日期"> <label for="cycleLength">经期周期长度 (天)：</label> <input id="cycleLength" type="number" placeholder="输入经期周期长度"><button οnclick="calculatePeriod()">计算</button><div id="result" class="result">结果将显示在这里</div></div>

JS:

function calculatePeriod() { const lastPeriodDate = new Date(document.getElementById('lastPeriod').value); const cycleLength = parseInt(document.getElementById('cycleLength').value); if (isNaN(lastPeriodDate.getTime()) || isNaN(cycleLength)) { document.getElementById('result').textContent = "请输入有效的日期和周期长度。"; return; } // 预测下一次月经的日期 const nextPeriodDate = new Date(lastPeriodDate); nextPeriodDate.setDate(lastPeriodDate.getDate() + cycleLength); // 预测排卵期(一般为周期的中间) const ovulationDate = new Date(lastPeriodDate); ovulationDate.setDate(lastPeriodDate.getDate() + cycleLength / 2); document.getElementById('result').innerHTML = `下一次月经日期：${nextPeriodDate.toLocaleDateString()}<br>` + `预计排卵日期：${ovulationDate.toLocaleDateString()}`; }

 CSS:

.calculator { width: 100%; background-color: #333; color: white; padding: 20px; border-radius: 10px; box-shadow: 0 5px 15px rgba(0, 0, 0, 0.3); } label { display: block; margin-bottom: 10px; font-size: 16px; } input, select { width: 100%!important; padding: 10px!important; margin-bottom: 20px; color: #000000; border-radius: 5px; border: 1px solid #555; font-size: 16px!important; background-color: #ffffff!important; } button { width: 100%; padding: 10px; background-color: #007bff; color: white; border: none; border-radius: 5px; cursor: pointer; font-size: 16px; } button:hover { background-color: orange; } .result { font-size: 18px; margin-top: 20px; text-align: center; } option { background-color: #ffffff; } p { font-size: 18px; margin-top: 5px!important; }
