Input

First Lets look at the simple input field validation. Note: You can use the inline props to get the inline label.

Usage

import React, { Component } from 'react'
import 'semantic-ui-css/semantic.css'; //Import the css only once in your project
import {Form,Input} from 'semantic-ui-react-form-validator'
import {Button} from 'semantic-ui-react';
class App extends Component {
  render () {
    return (
      <Form 
      ref="form"
      onSubmit={this.onSubmit} 
      >
        <Input 
          type="text"
          label="Test Input"
          onChange={(e)=>{this.setState({value:e.target.value})}} 
          value={this.state.value} 
          validators={['required']} 
          errorMessages={['this field is required']} 
          width={6} 
          />
          
        <Button color="teal">Submit<Button>
      </From>
    )
  }
}

width false int 12 width of the input field. 12 means it will match the parent width

    return (
      <Form 
      ref="form"
      onSubmit={this.onSubmit} 
      >
        <Dropdown

Validation Rules

Simple form validation component for react forms inspired by formsy-react

Default validation rules:

  • matchRegexp
  • isEmail
  • isEmpty
  • required
  • trim
  • isNumber
  • isFloat
  • isPositive
  • minNumber
  • maxNumber
  • minFloat
  • maxFloat
  • minStringLength
  • maxStringLength
  • isString
  • maxFileSize
  • allowedExtensions

Some rules can accept extra parameter, example:

<Input
   {...someProps}
   validators={['minNumber:0', 'maxNumber:255', 'matchRegexp:^[0-9]$']}
/>

Add Custom Validation

You can add your own rules

componentDidMount(){
    Form.addValidationRule('isFoo',value=>{
      var foo=/foo/;
      return foo.test(value)
    })
  }

check out app.js in example folder for more examples
