AJAX 形式 $('form')[0].reset();在提交时不清除值。我错过了什么？

Question

提前感谢您提供的任何帮助。我只是在学习 jQuery 和 AJAX，希望对以下代码有所帮助。所有验证规则都有效，表单提交并且页面不刷新。问题是在触发提交后表单值不是 clearing/resetting 默认值。想法？

通过输入 id="reset" and/or name="reset"，您有效地覆盖了表单的 form.reset 方法，因为通过这样做您创建了 form.reset 目标重置按钮。只需给它一个不同的 id 和 name 值。

永远不要给元素 name 或 id 属性等于 dom 节点的属性的名称。

AJAX form $('form')[0].reset(); on submit not clearing values. What am I missing?

submit-button
