Cannot read properties of undefined (reading '$children')

这个报错一般是因为访问了一个未定义的属性，具体来说是在读取一个未定义的对象或者数组的属性时发生的。根据引用和引用中提到的报错信息，其中的"$el"和"$children"都是未定义的属性，因此造成了报错。这种报错一般是由于前一个元素没有正确初始化导致的。在解决这个问题时，我们需要检查代码中前一个元素的定义和初始化是否正确。确保前一个元素已经正确定义并赋值，才能避免这种报错的发生。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
