这是一条规则，即int始终位于字符串的后面.

it is a rule that int is always in the back of the string.

如何获取字符串中最后一位的int

how i can get the int who was at last in my string

推荐答案

var s = 'abc123';
var number = s.match(/\d+$/);
number = parseInt(number, 10);

第一步是一个简单的正则表达式- \ d + $ 将匹配末尾的数字.
下一步，我们在之前匹配的 string 上使用 parseInt ，以获得正确的数字.

The first step is a simple regular expression - \d+$ will match the digits near the end.
On the next step, we use parseInt on the string we've matched before, to get a proper number.
