我试图以动态方式访问子表值,但我找不到合适/聪明的方法来执行此操作。以下是我想要实现的示例代码:
local var = "mySubTable1" --this value is different every time
local myTable = {
mySubTable1 = {"hello","world","goodbye","city"},
mySubTable2 = {"this", "is", "a", "test"},
...
}
print(myTable.var[3]) --I know this doesnt work, but how can I fix this?
答案 0 :(得分:1)
表格由以下关键字索引:
myTable[expression_that_evaluates_to_the_key]
如果键是一个字符串并且碰巧是一个有效的Lua标识符,那么可以使用这个语法糖:
myTable.mySubTable1
你已经知道那条捷径。回到基础:
print(myTable[var][3])
