How do I ask for a number to be entered when I enter a character other than a number in input?

<FormControl>
                <FormLabel>{isPay ? '추가 지급할 적립금' : '회수할 적립금'}</FormLabel>
                <OutlinedInput
                  type="number"
                  id="amount"
                  error={!!errors.amount}
                  {...register('amount', {
                    required: t('errors.required.field', {
                      field: 'amount',
                    }),
                    valueAsNumber: true,
                  })}
                  style={{ height: '40px' }}
                />
              </FormControl>

<FormControl>
                <FormLabel>{isPay ? '추가 지급할 적립금' : '회수할 적립금'}</FormLabel>
                <OutlinedInput
                  type="number"
                  id="amount"
                  error={!!errors.amount}
                  {...register('amount', {
                    required: t('errors.required.field', {
                      field: 'amount',
                    }),
                    valueAsNumber: true,
                  })}
                  style={{ height: '40px' }}
                />
              </FormControl>

Hi @florent. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- In your code, you are using the register function from react-hook-form to register the input field. The valueAsNumber: true option is used to ensure that the value entered is treated as a number. However, this does not prevent a user from entering non-numeric characters. To prevent non-numeric characters from being entered, you can add an onChange event handler to the OutlinedInput component that checks if the entered value is a number. If it's not, it can display an error message or prevent the character from being entered. Unfortunately, the knowledge sources provided do not contain a specific example of this. You may need to refer to the documentation or other resources for react-hook-form and Chakra UI's OutlinedInput component to implement this feature. Here is a general idea of how you might implement this:

<FormControl>
  <FormLabel>{isPay ? '추가 지급할 적립금' : '회수할 적립금'}</FormLabel>
  <OutlinedInput
    type="number"
    id="amount"
    error={!!errors.amount}
    {...register('amount', {
      required: t('errors.required.field', {
        field: 'amount',
      }),
      valueAsNumber: true,
    })}
    onChange={(event) => {
      const value = event.target.value;
      if (isNaN(value)) {
        // handle non-numeric input
      }
    }}
    style={{ height: '40px' }}
  />
</FormControl>

<FormControl>
  <FormLabel>{isPay ? '추가 지급할 적립금' : '회수할 적립금'}</FormLabel>
  <OutlinedInput
    type="number"
    id="amount"
    error={!!errors.amount}
    {...register('amount', {
      required: t('errors.required.field', {
        field: 'amount',
      }),
      valueAsNumber: true,
    })}
    onChange={(event) => {
      const value = event.target.value;
      if (isNaN(value)) {
        // handle non-numeric input
      }
    }}
    style={{ height: '40px' }}
  />
</FormControl>

In the onChange handler, isNaN(value) will return true if the value is not a number. You can replace the comment // handle non-numeric input with code to handle this case as you see fit. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai {...register('available_points', { required: t('errors.required.field', { field: 'available_points', }), How do I write that required phrase in locales?

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To define the required phrase in your locales, you need to add it to your translation file. The translation file is a JSON file that contains key-value pairs for different phrases in your application. Here is an example of how you can define the required phrase in your locales/en/common.json file:

{
  "errors": {
    "required": {
      "field": "The {{field}} is required"
    }
  }
}

{
  "errors": {
    "required": {
      "field": "The {{field}} is required"
    }
  }
}

In this example, {{field}} is a placeholder that will be replaced with the actual field name when the translation function t is called. So, when you use t('errors.required.field', { field: 'available_points' }), it will look for the key errors.required.field in the translation file and replace {{field}} with 'available_points', resulting in the string "The available_points is required". Please note that the structure of your translation file and the keys you use may vary based on your application's requirements and the structure you have defined for your translations. For more information, you can refer to the Refine documentation on internationalization (i18n) (https://refine.dev/docs/guides-concepts/i18n#adding-the-translations-files). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai https://mui.com/material-ui/react-text-field/ How do I create an input that only accepts numbers?

React Text Field component - Material UI

Text Fields let users enter and edit text.

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To create an input field that only accepts numbers in Material-UI, you can use the TextField component with the type prop set to "number". Here is a basic example:

import TextField from '@mui/material/TextField';

function NumberInput() {
  return (
    <TextField type="number" label="Numeric Input" />
  );
}

import TextField from '@mui/material/TextField';

function NumberInput() {
  return (
    <TextField type="number" label="Numeric Input" />
  );
}

This will render an input field that only accepts numeric input. However, please note that this does not prevent the user from typing non-numeric characters into the field. It only changes the behavior of the input field to be more suitable for numeric input (for example, by showing a numeric keyboard on mobile devices). If you want to prevent non-numeric characters from being entered entirely, you would need to add an onChange event handler that checks the entered value and prevents non-numeric characters from being entered. However, this is not covered in the provided knowledge sources. For more information, you can refer to the Material-UI TextField documentation (https://mui.com/material-ui/react-text-field/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
