考虑使用验证插件——它很棒!重置表单很简单:

var validator = $("#myform").validate();
validator.resetForm();

所以，在我最初回答这个问题的两年后，我回头看看，它已经变成了一个大混乱。我觉得是时候回到这个问题上来，让我的答案真正正确了，因为它得到了最多的好评和接受。

For the record, Titi's answer is wrong as it is not what the original poster asked for - it is correct that it is possible to reset a form using the native reset() method, but this question is trying to clear a form off of remembered values that would remain in the form if you reset it this way. This is why a "manual" reset is needed. I assume most people ended up in this question from a Google search and are truly looking for the reset() method, but it does not work for the specific case the OP is talking about.

我最初的回答是这样的:

// not correct, use answer below
$(':input','#myform')
.not(':button, :submit, :reset, :hidden')
.val('')
.removeAttr('checked')
.removeAttr('selected');

这可能适用于许多情况，包括OP，但正如评论和其他回答中指出的那样，将从任何值属性中清除单选/复选框元素。

一个更正确(但不完美)的答案是:

function resetForm($form) {
    $form.find('input:text, input:password, input:file, select, textarea').val('');
    $form.find('input:radio, input:checkbox')
         .removeAttr('checked').removeAttr('selected');
}

// to call, use:
resetForm($('#myform')); // by id, recommended
resetForm($('form[name=myName]')); // by name

jQuery认为，单独使用:text、:radio等选择器是一种糟糕的做法，因为它们最终会求值为*:text，这会花费比正常情况下更长的时间。我确实更喜欢白名单的方法，希望我在最初的回答中使用了它。无论如何，通过指定选择器的输入部分，加上表单元素的缓存，这应该使它成为这里性能最好的答案。

如果人们默认的选择元素不是一个空值的选项，那么这个答案可能仍然有一些缺陷，但它肯定是通用的，这将需要根据具体情况进行处理。

这里有一些东西可以让你开始

$('form') // match your correct form 
.find('input[type!=submit], input[type!=reset]') // don't reset submit or reset
.val(''); // set their value to blank

当然，如果你有复选框/单选按钮，你将需要修改这包括他们以及设置。attr({'checked': false});

编辑 Paolo的回答更加简洁。我的回答更啰嗦，因为我不知道:input选择器，也没有想过简单地删除选中的属性。

对paolo的答案进行了轻微的更新，以适应新的输入类型，如“tel”和电子邮件，以下代码片段也将选择这些类型:

function resetForm(form) {
    form.find('input:text, input[type=email], input[type=tel], input:password, input:file, select, textarea').val('');
    form.find('input:radio, input:checkbox')
         .removeAttr('checked').removeAttr('selected');
}

清除表单有点棘手，不像看起来那么简单。

建议你使用jQuery表单插件，并使用它的clearForm或resetForm功能。 它能解决大部分的极端情况。

A method I used on a fairly large form (50+ fields) was to just reload the form with AJAX, basically making a call back to the server and just returning the fields with their default values. This made is much easier than trying to grab each field with JS and then setting it to it's default value. It also allowed to me to keep the default values in one place--the server's code. On this site, there were also some different defaults depending on the settings for the account and therefore I didn't have to worry about sending these to JS. The only small issue I had to deal with were some suggest fields that required initialization after the AJAX call, but not a big deal.
