引用中提到的错误信息"[Vue warn]: Error in v-on handler: "TypeError: Cannot read properties of undefined (reading 'setCheckedKeys')"通常是由于在Vue的v-on事件处理程序中尝试访问未定义的属性而引起的。引用中指出,当点击按钮时,传递给实参cart的值为undefined,导致下面的skuId无法获取到值。这意味着在Vue组件中,可能存在未正确传递参数或未定义相关属性的问题。
在引用所提供的代码中,我未找到与错误信息中的"setCheckedKeys"相关的内容。可能是因为该代码片段不包含涉及到"setCheckedKeys"的逻辑。如果想要找到导致该错误的原因,需要进一步检查代码中与"setCheckedKeys"相关的部分,确保相应的属性被正确定义和传递。
解决这个问题的一种方法是确保在Vue组件中正确定义和初始化相关属性,以及在使用这些属性之前进行必要的检查和处理。另外,还可以通过调试工具来查找代码中具体出错的位置,并进行修复。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
