"TypeError: Cannot read properties of undefined (reading 'code')"报错如何解决

"TypeError: Cannot read properties of undefined (reading 'code')"报错通常是由于代码中尝试读取未定义或未初始化的属性而引起的。解决此问题的方法如下：
1. 确保代码中所引用的对象已经被正确地定义和初始化。
2. 检查代码中是否存在拼写错误或语法错误。
3. 确保代码中所引用的对象具有所需的属性。
4. 如果代码中使用了异步请求获取数据，请确保数据已经成功返回并被正确地处理。
5. 如果代码中使用了第三方库或插件，请确保它们已经被正确地引入并初始化。

Cannot read properties of undefined (reading 'code') TypeError: Cannot read properties of undefined (reading 'code')

TypeError: Cannot read properties of undefined (reading 'code') 是一个报错信息，表明在代码中尝试读取一个未定义的属性。这个错误通常发生在该属性的前一个元素没有正确定义的情况下。

根据提供的引用内容，有两个引用提到了这个错误。第一个引用中提到了这个错误一般发生在报错元素的前一个元素出了问题，即this.option没有获取到。第二个引用中提到了这个错误发生在红色区域，即代码尝试读取grid3D属性，但其前一个元素为undefined。

综合这两个引用内容，我们可以推断出解决这个错误的方法是确保前一个元素被正确定义。在第一个引用中，可以尝试检查this.option是否被正确赋值。在第二个引用中，可以尝试检查代码中是否正确获取到了鼠标元素，并确保该元素的grid3D属性存在。

通过以上的方法，您可以解决这个错误并正确读取属性。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
