我有一个表格可以将两个数字加在一起。我的问题是,它只有一个按钮,即添加按钮。让我们说我想添加一个取消按钮的处理程序,它将清除这两个框,我将如何实现它?

只需添加一个按钮即可重置表单。详细了解Reset button
无需添加任何处理程序来重置表单。
<button type="reset" value="Cancel">Cancel</button>
示例代码:
<html>
<body>
<form class="totalpayment">
<input class="paid" type="text" name="numberOne" />
<input class="due" type="text" name="numberTwo" />
<button>Add</button>
<button type="reset" value="Cancel">Cancel</button>
</form>
<p class="total"></p>
<script src="jquery.min.js"></script>
<script>
// Sum the value when submitting the form
$(".totalpayment").submit(function(e){
e.preventDefault();
var paid = parseInt($('.paid').val());
var due = parseInt($('.due').val());
$(".total").html(paid + due);
});
</script>
</body>
</html>
