除数字和小数点之外的所有内容都替换为Regex

I have a text field that needs to remain only text or decimal. Here is the code that I'm currently using to replace everything except numbers and a decimal point. Issue is, I can't figure out a regex that will identify everything else

我有一个文本字段，它只需要保留文本或小数。下面是我现在用的代码来替换除了数字和小数点之外的所有东西。问题是，我无法找到一个regex来标识其他所有内容

document.getElementById(target).value = newVal.replace(/\D[^\.]/g, "");

The \D works fine, but I've tried (?!.), (?!\.), [^.], [^\.] and so on...

\ D没问题,但我试过(? !),(? ! \),(^。],[^ \。)等等……

Any suggestions for a regular expression that identifies positively with anything except a number or a decimal?

对于正则表达式，除了一个数字或一个小数之外，还有什么建议吗?

Thanks for the help

Use this:

用这个:

document.getElementById(target).value = newVal.replace(/[^0-9.]/g, "");

#2

Removing only decimal part can be done as follows:

只去除小数部分可做如下操作:

number.replace(/(\.\d+)+/,'');

This would convert 13.6667px into 13px (leaving units px untouched).

这将把13.6667px转换成13px(单位px不变)。

Try this:

试试这个:

document.getElementById(target).value = newVal.replace(/^\d+(\.\d{0,2})?$/, "");

. getelementbyid(目标)。值= newVal.replace(/ ^ \ d +(\ \ d { 0,2 })?美元/”、“);

检查链接正则表达式演示

use the below reg exp

使用下面的reg exp。

[a-z] + [^0-9\s.]+|.(?!\d)

[a - z]+[^ 0 - 9 \]+ |。(? ! \ d)
