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.
