Question

请帮忙。

我创建了两个下拉列表，显示带有图标的所选复选框。问题是这两个下拉列表没有独立行动。

如果我在下拉列表中更改了某些内容（空间有什么安全性）下拉列表1中的所有内容也会被添加。

我需要下拉功能才能处理多个下拉列表。

注意：我需要在所选复选框中添加图标。即在显示所选复选框的dropdown-toggle div中：）

此外，所选复选框不会立即显示。我需要再次点击它才能显示所选的复选框

Answer 1

您的代码存在的问题是$(" .checkbox-list li input:checked + label")不依赖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 the更改事件 - 之间存在差异，因此无法识别第一个值。

我改变了你的代码：

$('.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>');

  });

});
