{
return value.match(new RegExp("^" + param + "$"));
});

/^[a-z0-9\-\s]+$/ishould do the trick!
/^[a-z0-9\-\s]+$/i应该做的伎俩！
g = /g modifier makes sure that all occurrences of "replacement"
g = /g 修饰符确保所有出现的“替换”
i = /i makes the regex match case insensitive.
i = /i 使正则表达式匹配不区分大小写。

I think it will work if you pass the following RegExp as param:
我认为如果您将以下 RegExp 传递为param：
[A-za-z0-9_\-\s]+
