如何使用正则表达式从字符串中获取第二个:后的整数？

请参阅示例：

input: '<a:test:398324781412777419>' ==> output: '398324781412777419'
input: '<a:10test:391278741412111419>' ==> output: '391278741412111419'
input: '<a:test10:123487466611419>' ==> output: '123487466611419'

Answer 1

您可以使用正则表达式查找数字和后续>。

正则表达式有两部分，

/\d+(?=>$)/
 ^^^         search for digits
    (?=  )   pattern for positive lookahead (the part is not included in the result)
       >$    looks for character > and for end of string

var string = '<a:test:398324781412777419>',
    number = string.match(/\d+(?=>$)/)[0];
    
console.log(number);

Answer 3

使用.replace(/[^:]?[^:]?(\D)/g, '')。

实施例： '<a:test10:398324781412777419>'.replace(/[^:]?[^:]?(\D)/g, '') // will return '398324781412777419'
