react-inputs-validation

React form input validation components.

:tada: For version >= 3.0.0, please update react and react-dom to at least 16.8.6, since it is rewrited with hooks.

  "peerDependencies": {
    "react": "^16.8.6",
    "react-dom": "^16.8.6"
  }

For version >= 1.1.4, please import css manually.

import { Textbox, Textarea, Radiobox, Checkbox, Select } from 'react-inputs-validation';
import 'react-inputs-validation/lib/react-inputs-validation.min.css';

Codesandbox Examples

• Online demo form example playground
• Custom control(when check: false)
• Custom function(when providing customFunc)
• Custom function further control(when providing customFunc)
• Custom locales(when providing window.REACT_INPUTS_VALIDATION['customErrorMessage'])
• Phone and email validation example(handled with customFunc)

Custom Error Message (can be multiple locales)

By providing window.REACT_INPUTS_VALIDATION['customErrorMessage'], you can overwrite the error message.

IMPORTANT NOTE: YOU WILL NEED TO PLACE window.REACT_INPUTS_VALIDATION BEFORE YOUR JS SCRIPT

example(fully customized):

</script>
<script type="text/javascript" src="/js/index.js"></script></body>

Then in the component...

<Textbox
  tabIndex="1" //Optional.[String or Number].Default: none.
  ...
  validationOption={{
    ...
    locale: 'my-own-locale'
    ...
  }}
 />

For more extensibility or customization please reffer to 'validationOption.customFunc'
