正则表达式的数字介于0到100之间? [英] Regex for number between 0 to 100?
问题描述
它不应该允许前导零,例如 099
.允许的值应如下所示: 35
, 99
, 1
, 2
, 3
, 100
.
It should not allow leading zeroes, like 099
. Allowed values should be like these: 35
, 99
, 1
, 2
, 3
, 100
.
这是我尝试过的:
$('#createCoupon_discountAmount').bind('input propertychange', function () {
$(this).val($(this).val().replace(/(\d\d?|100)\Z/g, ''));
});
推荐答案
我将为此使用的正则表达式如下,但是我不确定它是否是最佳的:
The regex that I would use for this is the following, but I'm not sure if it an optimal one:
^([0-9] |([1-9] [0-9])| 100)$
我们创建三个组,并且始终从字符串的开头到结尾进行匹配.我们捕获的第一组是 [0-9]
,以获得前10个数字(0-9).第二组我们两次捕获这些数字,以从10-> 99获得所有数字.最后我们也匹配100.
We create three groups and we always match from the beginning of the string to the end. The first group we capture is [0-9]
to get the first 10 numbers (0-9). The second group we capture those numbers twice, to get all numbers from 10 -> 99. And finally we just match 100 as well.
