Let's say I have an input field and want to parse all of the numbers from the submitted string. For example, it could be:
假设我有一个输入字段，想要解析提交的字符串中的所有数字。例如，它可能是：
Hi I'm 12 years old.
How do I parse all of the numbers without having a common pattern to work with?
如何在不使用通用模式的情况下解析所有数字？
I tried:
我试过了：
x.match(/\d+/)
but it only grabs the 12 and won't go past the next space, which is problematic if the user inputs more numbers with spaces in-between them.
但它只能抓住12并且不会越过下一个空间，如果用户输入更多带有空格的数字，这就有问题。

Add the g flag to return all matches in an array:
添加g标志以返回数组中的所有匹配项：
var matches = x.match(/\d+/g)
However, this may not catch numbers with seperators, like 1,000 or 0.123
但是，这可能无法与分离器捕获数字，如1,000或0.123
You may want to update your regex to:
您可能希望将正则表达式更新为：
x.match(/[0-9 , \.]+/g)

var words = sentence.split(" ");
var numbers = words.filter(function(w) {
