TypeError: Cannot read properties of null (reading 'nextSibling')

这个错误是由于尝试读取一个null值的属性引起的。在你的代码中,出现了类似于读取null的属性 'nextSibling' 的操作,但是前面的变量值是null,所以无法继续读取其属性。要解决这个问题,你需要在使用该属性之前,确保变量的值不是null。可以通过检查变量是否为null来进行判断,然后再进行相应的操作。例如,在使用'nextSibling'属性之前,你可以先对变量进行判空,如果变量为null,则不进行相应操作,否则才继续使用该属性。这样可以避免出现TypeError: Cannot read properties of null的错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
