[英]Custom Validation with React Final Form
I am trying to add some custom validations of allowing only number(amout) in the input boxes.我正在尝试在输入框中添加一些仅允许数字(金额)的自定义验证。 As per the example given on here , I tried to add custom validation.
根据此处给出的示例,我尝试添加自定义验证。
const onlyAmount = value => {
if (!value) return value
let onlyNums = value.replace(/^\$?([0-9]{1,3},([0-9]{3},)*[0-9]{3}|[0-9]+)(.[0-9][0-9])?$/, '')
return onlyNums
}
and field of my final form is like我的最终形式的领域就像
<Field
name="price"
component="input"
type="text"
parse={onlyAmount}
/>
No the problem, its not allowing me to add numbers properly.没问题,它不允许我正确添加数字。 I read the docs of the but couldn't find any helping solution.
我阅读了 的文档,但找不到任何帮助解决方案。
React Final Form : https://github.com/final-form/react-final-form反应最终形式: https : //github.com/final-form/react-final-form
Any suggestions will be really helpful.任何建议都会非常有帮助。
Add just type="number".添加类型=“数字”。 The keyboard will not allow other than numbers.
键盘不允许除数字以外的其他字符。
type="hidden"
seems like a mistake. type="hidden"
似乎是个错误。 Won't that result in a <input type="hidden"/>
?这不会导致
<input type="hidden"/>
吗?
I have not mentally parsed your regex, but I'd recommend you try testing your parse function in that sandbox that you linked to and see why it's not working.我没有在精神上解析您的正则表达式,但我建议您尝试在您链接到的沙箱中测试您的解析函数,看看它为什么不起作用。
It's your regex.这是你的正则表达式。 If you add a console to print out your value, then your onlyNum, you get empty string.
如果你添加一个控制台来打印你的值,那么你的 onlyNum,你会得到空字符串。
