前端Button点击无反应--记一次Debug经历

最近在学习秒杀系统，前端有个秒杀按钮，显示什么都正常，就是点击无反应，复制人家提供的源代码发现是表单的单词拼错了，form拼成了from，小细节。

<!--错误代码-->
<from id="secKillForm" method="post" action="/secKill/doSeckill">
                    <input type="hidden" name="goodsId" th:value="${goods.id}">
                    <button class="btn btn-primary btn-block" type="submit" id="buyButton">立即秒杀</button>
</from>


<!--正确代码-->
<form id="secKillForm" method="post" action="/secKill/doSeckill">
                    <input type="hidden" name="goodsId" th:value="${goods.id}">
                    <button class="btn btn-primary btn-block" type="submit" id="buyButton">立即秒杀</button>
</form>
