jQuery：如何从一条路径中选择多个元素？

Question

I'm curious if there is a way to condense this:

$('foo input:checkbox, foo input:radio');

---

I tried the following but no luck:

•  $('foo input[type="checkbox",type="radio"]'); 

  This blindly doesn't work (prob bad syntax)
  

•   $('foo input[type="checkbox"][type="radio"]'); 

  I think this would select all inputs that are both radio and checkbox, which won't ever be the case.

---

Edit:
I changed fooElement to foo toi simplify the example

Answer 1

$('input[type="checkbox"], input[type="radio"]', $('fooelement'))

Or

$('[type="checkbox"], [type="radio"]', $('fooelement input'))

Or

$(':checkbox, :radio', $('fooelement input'))

Remember jQuery offers the abiltiy to specify a context to search in.

Answer 2

尝试这个

$('fooElement input').filter(":checkbox, :radio");

Answer 3

$('fooElement').find(':checkbox,:radio');

Answer 4

$('fooElement input[type="checkbox"]').add('fooElement [type="radio"]');

Answer 5

它本身并不是真正的“压缩”，而是：

$('fooElement input[type="checkbox"], fooElement input[type="radio"]');
