Lua if语句嵌套
在Lua编程内嵌if-else语句,这意味着可以使用一个 if 或 else if 在另一个语句if或else if 语句中。
语法
if语句的嵌套语法如下:
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
您可以嵌套else if...else 以类似if语句的方式。
例子:
--[ 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 );
当建立和运行上面的代码,它会产生以下结果。
Value of a is 100 and b is 200 Exact value of a is : 100 Exact value of b is : 200
