精简一下
/^(0|[1-9]\d*)(.\d+)$/.test(0.23)
// => true
原示例修改
- /^[0-9]+(.[0-9]{2})?$/.test(0.000) //=> true
+ /^[0-9]+(.[0-9]{2})$/.test(0.000) //=> false
/^[0-9]+(.[0-9]{2})$/.test(0.000) //=> false
from regexp-example.
/^(0|[1-9]\d*)(.\d+)$/.test(0.00)
//=> false
你这个正则也不太行

换成字符串就行了,而且我觉得 /^(0|[1-9]\d*)(.\d+)?$/ 应该需要,在写业务中,用来校验表单的
/^(0|[1-9]\d*)(.\d+)$/.test('0.00')
//=> true
from regexp-example.
@cuilanxin 已经更改

非零,俩位,最大 99999999.99
/^(0|[1-9]\d{0,7}).?(([1-9]{1,2}?)|(0[1-9]))$/g
from regexp-example.
@cuilanxin 已添加

非零,最多俩位小数
/^(?!^0(.0{1,2})?$)\d*(\.\d{1,2})?$/g
from regexp-example.
