如何将所有选定的复选框附加到span中

Question

请帮帮忙。

我创建了两个下拉列表，显示带有图标的选中复选框。问题是，这两次跌落并不是独立行动。

如果我在下拉列表2(空间有什么安全性)中更改了一些内容，那么下拉列表1中的所有内容也会被添加进来。

​

我需要下拉功能来处理多个下拉列表。

注意:我需要在选中的复选框中添加我的图标。在显示所选复选框的下拉-切换div中的ie :)

此外，所选复选框没有立即显示。我需要再次单击它，以显示选中的复选框。

Answer 1

代码的问题是，$(" .checkbox-list li input:checked + label")并不取决于调用处理程序的下拉列表。此外，由于输入的click-event of the label and thechange`之间的离散性，第一个值无法识别。

我稍微修改了你的代码：

$('.checkbox-list input').on('change', function() {
  var $this = $(this).parents('.checkbox-list');
  var features_checkedBox = [];

  $this.find('input:checked').each(function() {

    allChecked = $(this).next('label').html();
    features_checkedBox.push(allChecked);
    $(this).parents('.dropdown').find('.dropdown-toggle').html('<span class="selections">' + features_checkedBox + '<i class="glyphicon glyphicon-menu-down"> </i> </span>');

  });

});
