无涯教程-Lua - 嵌套if语句函数
在Lua编程中,您可以在另一个if or else if语句中使用一个if or else if语句。
nested if statements - 语法
嵌套if 语句的语法如下-
if( boolean_expression 1) then --[ Executes when the boolean expression 1 is true --] if(boolean_expression 2) then --[ Executes when the boolean expression 2 is true --] end end
您可以像嵌套 if 语句一样,嵌套 else if ... else 。
nested if statements - 示例
--[ local variable definition --] a=100; b=200; --[ check the boolean condition --] if( a == 100 ) then --[ if condition is true then check the following --] if( b == 200 ) then --[ if condition is true then print the following --] print("Value of a is 100 and b is 200" ); end end print("Exact value of a is :", a ); print("Exact value of b is :", b );
当您构建并运行以上代码时,它将产生以下输出。
Value of a is 100 and b is 200 Exact value of a is : 100 Exact value of b is : 200
