保罗接受的答案有个大问题。考虑:

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

.val(")行还将清除分配给复选框和单选按钮的任何值。所以如果你(像我一样)做这样的事情:

<input type="checkbox" name="list[]" value="one" />
<input type="checkbox" name="list[]" value="two" checked="checked" />
<input type="checkbox" name="list[]" value="three" />

使用公认的答案会将你的输入转换为:

<input type="checkbox" name="list[]" value="" />
<input type="checkbox" name="list[]" value="" />
<input type="checkbox" name="list[]" value="" />

哎呀——我正在使用这个值!

下面是一个修改后的版本，将保留您的复选框和无线电值:

// Use a whitelist of fields to minimize unintended side effects.
$('INPUT:text, INPUT:password, INPUT:file, SELECT, TEXTAREA', '#myFormId').val('');  
// De-select any checkboxes, radios and drop-down menus
$('INPUT:checkbox, INPUT:radio', '#myFormId').removeAttr('checked').removeAttr('selected');

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。

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.

考虑使用验证插件——它很棒!重置表单很简单:

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

我对弗朗西斯·刘易斯的解决方案做了一点改动。他的解决方案没有做的是将下拉选择设置为空白。(我认为当大多数人想要“清除”时，他们可能想让所有值为空。)这个是用。find('select')。道具(“selectedIndex”,1)。

$.fn.clear = function()
{
    $(this).find('input')
            .filter(':text, :password, :file').val('')
            .end()
            .filter(':checkbox, :radio')
                .removeAttr('checked')
            .end()
        .end()
    .find('textarea').val('')
        .end()
    .find('select').prop("selectedIndex", -1)
        .find('option:selected').removeAttr('selected')
    ;
    return this;
};

Paolo的回答没有考虑日期选择器，添加这个:

$form.find('input[type="date"]').val('');
