我正在制作一个表单，我有一个函数来重置所有字段，我有一个函数来验证字段。我有两个按钮，发送电子邮件和重置表单。发送邮件按钮为type = "submit"，复位按钮为简单按钮。
问题是当我点击重置按钮时，它执行发送函数，这就像浏览器认为重置按钮正在提交表单。

</html>因为<form>标签中的<button>总是充当submit，除非您另有指定。
为了修复这种行为，您可以添加type="button"或专用type="reset"属性:
<button
id="resetBtn"
type="button"
class="w-full bg-green-600 px-2 py-5 text-white items-center uppercase font-bold items-center flex justify-center">Reset Form<i class="material-icons right ml-3"></i>
</button>
