我有下一个标记结构：

​

代码语言：javascript
复制
$(function() {
  $('#condition-container').on('click', '.component-delete', function() {
    var component = $(this).parents('.workflow-component');
    component.closest('.hr').remove(); //Delete nothing
    //component.siblings('.hr').remove();//delete all hr but I need to delete only closest
    component.remove();
  });
});

​

问题是，我希望通过单击按钮Delete删除最接近的.hr块，但在第一种情况下，它不删除任何东西，而在另一种情况下，它删除所有.hr块。

预期行为：

  1. 如果我单击第二个或另一个块的Delete按钮，它必须删除第一个上块.hr
  2. 如果我点击第一个元素，必须删除下一个.hr块。

如何根据示例中的代码实现这种行为？

jquery

您需要使用.next()来跟踪兄弟姐妹。.closest()方法从自身开始遍历。

代码语言：javascript
复制
component.next('.hr').remove();

代码语言：javascript
复制
$(function() {
  $('#condition-container').on('click', '.component-delete', function() {
    var component = $(this).parents('.workflow-component');

    component.remove();
  });
});
