Error in v-on handler: "TypeError: Cannot read properties of undefined (reading 'push')" found in

引用\[1\]中的错误信息是"TypeError: Cannot read properties of undefined (reading 'skuId')"，这个错误通常是因为在代码中尝试读取一个未定义的属性。在引用\[2\]中的代码中，可以看到在调用`this.$store.dispatch('addOrUpdateShopCart',{skuId:cart.skuId,skuNum:disNum})`时，传递给`addOrUpdateShopCart`方法的参数`cart`可能是未定义的，导致无法读取`skuId`属性。这可能是因为在调用`handler`方法时，没有正确传递`cart`参数或者`cart`参数的值为`undefined`。需要检查代码中调用`handler`方法的地方，确保正确传递了`cart`参数并且`cart`参数的值不为`undefined`。另外，也可以在调用`handler`方法之前添加一些代码来确保`cart`参数的值不为`undefined`，例如使用条件语句进行判断。
