jquery - 如何有效地清除/休息表格？

Question

我有一个textarea, someinput[type=text]和 other的表格input[type=file]。我通过 Jquery Form 插件提交表单，然后我无法以任何方式清除/休息表单。我尝试了 clearFrom 和 resetForm 表单插件选项和其他一些，但似乎都没有

HTML

<form action="validade_main_cenas.php" method="POST" enctype="multipart/form-data" class="post-cenas-form" id="post-cenas-form" name="post_cenas_form">

                $('#image-preview').attr('src', e.target.result);
            }
            reader.readAsDataURL(input.files[0]);
        }

Answer 1

您可以使用：

$('#FORM-ID').reset();

更新：忘了提到你应该用这个函数扩展 jQuery：

    jQuery.fn.reset = function () {
       $(this).each (function() { this.reset(); });
    }
