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

这个错误的原因是试图读取一个null对象的属性'getAttribute'，在使用getAttribute()之前，应该首先检查该属性所属的对象是否为null。这个错误通常发生在代码中尝试使用某个变量或对象的属性时，该变量或对象的值为null，而不是预期的对象。你可以通过检查该属性所属的对象是否为null来解决这个错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
