如何有效清除/放置表單？

Question

我有一個表格textarea，一些input[type=text]和其他input[type=file]。我通過Jquery Form插件提交表單，但我無法通過任何方式清除/休息表單。我試過clearFrom和resetForm形式的插件選項和一些其他的，沒有似乎工作

HTML

Answer 1

您可以使用：

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

UPDATE： 忘了提，你應該使用此功能擴展jQuery的：

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