如何增加表中的变量并访问它？

Question

我有一个表定义如下：

local counter = {    
deleted = 0,    
moved = 0,    
sumOfFileSize = 0,    
}    

我尝试过以下方法来增加或获取值，但它不起作用：

增量：counter.deleted = counter.deleted + 1

获取：counter.deleted

如何成功修改或阅读这些值？

Answer 1

如果你在某些功能中使用你需要声明whitout本地，而你可以用文件顶部声明它

counter={deleted = 0,
 moved = 0,
 sumOfFileSize = 0}

用于访问您想要的所有功能。

问题来自另一个地方，因为我在控制台中尝试这个，这里是结果，所以问题不是lua

counter = {
 deleted = 0,
 moved = 0,
 sumOfFileSize = 0,
 }
 print(counter)
table: 0x7fb1e2e005d0
 counter.deleted = counter.deleted + 1

 print(counter.deleted)
1
 counter.deleted = counter.deleted + 1
 print(counter.deleted)
2
 counter.deleted = counter.deleted + 1
 print(counter.deleted)
