Question

我已经实现了这个选择列表，由Volker Otto在Codepen上提供： http://codepen.io/l4ci/pen/gPjYma/

我觉得它对我来说很完美，但是我不知道如何处理这个选择列表的用户选择，因为它不是一个选项列表。

任何想法？

查找以下标记，css和js：

.select {
  position: relative;
  display: block;
  margin: 0 auto;
  width: 100%;
  max-width: 325px;
  color: #cccccc;
  vertical-align: middle;
  text-align: left;
  user-select: none;
  -webkit-touch-callout: none;
}
.select .placeholder {
  position: relative;
  display: block;
  background-color: #393d41;
  z-index: 1;
  padding: 1em;
  border-radius: 2px;
  cursor: pointer;
}
.select .placeholder:hover {
  background: #34383c;
}
.select .placeholder:after {
  position: absolute;
  right: 1em;
  top: 50%;
  transform: translateY(-50%);
  font-family: 'FontAwesome';
  content: '\f078';
  z-index: 10;
}
.select.is-open .placeholder:after {
  content: '\f077';
}
.select.is-open ul {
  display: block;
}
.select ul {
  display: none;
  position: absolute;
  overflow: hidden;
  width: 100%;
  background: #fff;
  border-radius: 2px;
  top: 100%;
  left: 0;
  list-style: none;
  margin: 5px 0 0 0;
  padding: 0;
  z-index: 100;
}
.select ul li {
  display: block;
  text-align: left;
  padding: 0.8em 1em 0.8em 1em;
  color: #999;
  cursor: pointer;
}
.select ul li:hover {
  background: #4ebbf0;
  color: #fff;
}

$('.select').on('click','.placeholder',function(){
  var parent = $(this).closest('.select');
  if ( ! parent.hasClass('is-open')){
    parent.addClass('is-open');
    $('.select.is-open').not(parent).removeClass('is-open');
  }else{
    parent.removeClass('is-open');
  }
}).on('click','ul>li',function(){
  var parent = $(this).closest('.select');
  parent.removeClass('is-open').find('.placeholder').text( $(this).text() );
});

$('.select').on('click', '.placeholder', function() {
  var parent = $(this).closest('.select');
  if (!parent.hasClass('is-open')) {
    parent.addClass('is-open');
    $('.select.is-open').not(parent).removeClass('is-open');
  } else {
    parent.removeClass('is-open');
  }
}).on('click', 'ul>li', function() {
  var parent = $(this).closest('.select');
  parent.removeClass('is-open').find('.placeholder').text($(this).text());
});

Answer 1

您可以使用它来获取jquery中的值：

jQuery('div.select .placeholder').html();

Answer 2

＆＃13;

$('.select').on('click', '.placeholder', function() {
  var parent = $(this).closest('.select');
  if (!parent.hasClass('is-open')) {
    parent.addClass('is-open');
    $('.select.is-open').not(parent).removeClass('is-open');
  } else {
    parent.removeClass('is-open');
  }
}).on('click', 'ul>li', function() {
  
  alert($(this).text())//this is the value of the text you selected
  var parent = $(this).closest('.select');
  parent.removeClass('is-open').find('.placeholder').text($(this).text());
});
