清除 HTML 表格的一部分（重置按钮）

Question

我的联系表有两列。有没有办法为每列设置一个重置按钮，或者只选择部分字段的按钮？

所以在这个例子中，第二个按钮只清除右列（例如重置所有单选按钮）

Answer 1

重置按钮不会重置表单的一部分，如果您需要使用按钮重置表单的一部分，您可以尝试使用 jquery，例如

将重置按钮更改为简单按钮， id 属性最初添加到重置按钮和表单以轻松访问它们

<input class="button" type="button" id="B2" name="B2" value="Zurcksetzen">

然后在按钮上分配一个点击事件如下

$(document).ready(function(){
    $("#B2").click(function(){
        $('#my-form').find('input:checkbox').prop('checked', false);
    });
});

下面是帮助重置所有类型的表单元素的代码，您可以保留任何您想要重置的内容并删除您不想重置的内容。

$('#my-form').find('input:text, input:password, select, textarea').val('');
$('#my-form').find('input:radio, input:checkbox').prop('checked', false);

您的问题听起来与此类似：reset value of multiple (but not all) form fields with jQuery in one line

你可以用同样的方法解决它 jQuery。
