Since he wants the form to reset it self automatically he can make a hidden reset button and make it click on submit.
由于他希望表单自动重置它，他可以制作一个隐藏的重置按钮并点击提交。
<input type="reset" id="reset_button" style="display:none"/>
Then click the button by its id on submit of the form.
然后在提交表单时按其 id 单击按钮。
$('reset_button').click();

IMO this.form.elements[]is a collection array and you can access individual elements by passing either index or element name
IMOthis.form.elements[]是一个集合数组，您可以通过传递索引或元素名称来访问单个元素
For example, this.form.elements[0].value=''
例如， this.form.elements[0].value=''
OR
或者
this.form.elements['email'].value='', this.form.elements['password'].value=''
this.form.elements['email'].value='', this.form.elements['password'].value=''
I am not sure if you can really pass the class name to it to access all elements with that class name. To reset all elements in the form, you can use this.form.reset()
我不确定您是否真的可以将类名传递给它以访问具有该类名的所有元素。要重置表单中的所有元素，您可以使用this.form.reset()
