如何隐藏自定义选择列表中的选定选项？

Question

我有一个非常好的自定义选择列表代码，它几乎完美，除了已经选择的显示选项。任何人都可以帮我简单地隐藏它吗？就像汽车＆＃39;已选中，您再次单击选择字段，它不应显示＆＃39; car＆＃39;在列表中，但所有其他人。我需要更多文字，所以我提前感谢任何人的时间。

以下是代码：

＆＃13;

＆＃13;

$(document).ready(function() {
  enableSelectBoxes();
});

function enableSelectBoxes() {
  $('div.selectBox').each(function() {
    $(this).children('span.selected').html($(this).children('ul.selectOptions').children('li.selectOption:first').html());
    $('input.price_values').attr('value', $(this).children('ul.selectOptions').children('li.selectOption:first').attr('data-value'));

    $(this).children('span.selected,span.selectArrow').click(function() {
      if ($(this).parent().children('ul.selectOptions').css('display') == 'none') {
        $(this).parent().children('ul.selectOptions').css('display', 'block');
      } else {
        $(this).parent().children('ul.selectOptions').css('display', 'none');
      }
    });

    $(this).find('li.selectOption').click(function() {
      $(this).parent().css('display', 'none');
      $('input.price_values').attr('value', $(this).attr('data-value'));
      $(this).parent().siblings('span.selected').html($(this).html());
    });
  });

当您选择任何选项时，显示所有选项并隐藏您选择的选项。

由于li.selectOption为display: block，您只需使用.show()即可显示它们。

$(this).find('li.selectOption').click(function() {
    // show all the options
    $(this).siblings().show()
    // hide the one you selected
    $(this).hide()
    $(this).parent().css('display', 'none');
    $('input.price_values').attr('value', $(this).attr('data-value'));
    $(this).parent().siblings('span.selected').html($(this).html());
});

＆＃13;

＆＃13;

$(document).ready(function() {
  enableSelectBoxes();
  // after the select boxes are initialized, click the first option
  $('ul.selectOptions li.selectOption:first').click();
});

function enableSelectBoxes() {
  $('div.selectBox').each(function() {
    $(this).children('span.selected').html($(this).children('ul.selectOptions').children('li.selectOption:first').html());
    $('input.price_values').attr('value', $(this).children('ul.selectOptions').children('li.selectOption:first').attr('data-value'));

    $(this).children('span.selected,span.selectArrow').click(function() {
      if ($(this).parent().children('ul.selectOptions').css('display') == 'none') {
        $(this).parent().children('ul.selectOptions').css('display', 'block');
      } else {
        $(this).parent().children('ul.selectOptions').css('display', 'none');
      }
    });

    $(this).find('li.selectOption').click(function() {
      // show all the options
      $(this).siblings().show()
      // hide the one you selected
      $(this).hide()
      $(this).parent().css('display', 'none');
      $('input.price_values').attr('value', $(this).attr('data-value'));
      $(this).parent().siblings('span.selected').html($(this).html());
    });
  });
