推荐答案

步骤：

1.基于''。''作为分隔符，将变量拆分为数组

2.如果确定变量的格式始终为xxx，请检查第二个值。 yyy

3.如果数组长度大于1，则根据定义的格式，变量包含扩展名。



参考： JavaScript split（）方法 [ ^ ]



试用。

Steps:
1. Based on ''.'' as a delimiter, split the variable into array
2. Check the 2nd value if you are sure that variable will always be of format xxx.yyy
3. If array length is more than one, based on the defined format, variable contains extension.
