# 报错: 'local_var' is not defined 在这个例子中,变量local_var是在function_example函数内部声明的,因此它是一个局部变量。这意味着local_var只能在function_example内部被访问。尝试在函数外部访问local_var将会导致一个错误,因为local_var在这个作用域外是不可见的。
When working with a framework like Next.js that executes code on the server side, using localStorage produces an error like "localStorage is not defined" or "window is not defined" To fix this, check to see if window is defined so that the code will run only when it's available. This ...

In your example, the type &Thing is only defined inside the scope of the main function. The lint warning is complaining that the impl for that type is not hoisted out of the function to the top level of the module, which is patently impossible. It would be similarly impossible for any ...

The layer oxide NCM in this study is a mixed conductor with a high ionic and electronic conductivity16, therefore the bulk diffusion in NCM particles is not limited. The surrounded solid-state electrolyte, however, ...
TableQuery object to the UI directly is not the proper way to present data, so a new ObservableCollection<Customer> based on the returned result is generated and assigned to the Customers property. The code also invokes a method called AddNewCustomer if the table is empty, defined as follows:...
