按名称获取表单元素？ [英] Get form elements by name?

问题描述

我想用一个很好的Prototype或jQuery风格的快捷方式轻松地将所有具有相同名称的单选按钮样式化。

$（'billship'）。select（'name：shipType'）或类似的东西。

字段名称是否存在？

解决方案

使用jQuery：

  $（'＃billship input：radio [name =shipType]'）; 
 $（'input：radio [name =shipType]'，'#billship'）; 
  

两者相同，但第二个表现稍好，我个人更喜欢它。

使用Prototype，我认为它看起来像这样：

  $$（' #billship input [type =radio] [name =shipType]'）; 
  

I would like to style all of the radio buttons with the same name in a form easily in a nice Prototype or jQuery-style shortcut.

$('billship').select('name:shipType') or something like that.

Does such a shortcut for form field names exist?

解决方案

With jQuery:

$('#billship input:radio[name="shipType"]');  
$('input:radio[name="shipType"]', '#billship');

Both are equivalent, but the 2nd one performs slightly better and I personally prefer it.

With Prototype, I believe it would look like this:

$$('#billship input[type="radio"][name="shipType"]');
