正则表达式从字符串中拆分数字 [英] regex to split number from string

问题描述

如何使用正则表达式拆分和选择数字.用户可以输入如下字符串:

How to split and select which is number using regex. User can enter string like:

1打3打打1 <=不太可能但假设用户也会输入

1dozen 3 dozen dozen1 <= unlikely but assume user will type that too

30/公斤

我还是找到了不完整的:

I still find out with the incomplete one:

/[a-z](?=\d)|\d(?=[a-z])/i

但缺少空格和正斜杠.有人可以帮我吗?

But missing space and forward slash. Can anyone help me?

推荐答案

这里完全不需要环顾！

参见 http://jsfiddle.net/5WJ9v/

代码:

var text = "1dozen 3 dozen dozen1 30/kg";
var regex = /(\d+\.|\d+)+/g;
alert(text.match(regex));

您会得到一个包含所有号码的匹配对象.

You get a match object with all of your numbers.

上面的脚本正确地提醒1,3,1,30.

The script above correctly alerts 1,3,1,30.
