javascript - 在 <a> 之前的多个元素之前搜索 <select>

Question

如何搜索 select <a> 之前的多个元素之前的元素？

我知道$('select[name=foo]').val())

    <select name="foo">
      <option value="1">1</option>
      <option value="2">3</option>
      <option value="2">3</option>
    </select>

    <div class="foo2"></div>
    <p>Lorem Ipsum</p>

    <a class="button" href="#">Search</a>

这是我的尝试:

$('a').click(function(e){
  e.preventDefault();
  console.log($(this).prevUntil('select'));
});

Answer 1

使用prevUntil将为您提供选择器中元素之前的所有元素

来自文档:

Description: Get all preceding siblings of each element up to but not including the element matched by the selector, DOM node, or jQuery object.

您想使用 prevAll('select:first') 获取前一个选择 http://api.jquery.com/prevall/

Description: Get all preceding siblings of each element in the set of matched elements, optionally filtered by a selector.

$(this).prevAll('select:first')
