在一行中用jQuery重置多个（但不是全部）表单字段的值 [英] reset value of multiple (but not all) form fields with jQuery in one line

问题描述

是否可以使用jQuery重置一行或一次命中中的多个表单域。注意：我不想重置所有表单字段，只需指定白名单（如下所示）：

Is it possible to reset multiple form fields in one line, or one hit, with jQuery. Note: I don't want to reset all form fields, only a specified whitelist (as below):

// reset some form fields                       
$('#address11').val('');
$('#address21').val('');
$('#town1').val('');
$('#county1').val('');
$('#postcode1').val('');

推荐答案

jQuery（和CSS）选择器字符串可以包含多个选择器使用逗号作为子选择符的分隔符：

jQuery (and CSS) selector strings can contain multiple selectors using a comma as a delimiter for sub-selectors:

$('#address11, #address21, #town1, #county1, #postcode1').val('');

我认为这比使用类更快查询应该在基本不变的时间内执行，而类查找将不得不访问每个DOM节点），但如果要更改哪些元素会被重置，则可能无法维护。

I'd argue that this is faster than using a class (ID look-ups should perform in essentially constant time, whereas a class look-up will have to visit every DOM node), but perhaps less maintainable if you're going to want to change which elements get reset.
