react-radio

A carefully crafted radio-group for React

See demo at zippyui.github.io/react-radio

Install

$ npm install react-radio

Usage

var RadioGroup = require('react-radio')

var colors = [
    {
        value: 'red',
        label: 'Red color',
        style: {
            color: 'red'
        }
    },
    'blue',
    'orange'
]

function onChange(value, event){
    console.log('checked ', value)
}

//uncontrolled
<RadioGroup
    name="colors"
    defaultValue={'red'}
    items={colors}
    onChange={onChange}
/>

var COLOR = 'red'
//controlled
<RadioGroup name="colors" value={COLOR} items={colors} onChange={onChange} />

<RadioGroup name="colors" value={'red'} onChange={onChange}>
    <input type="radio" value="blue" />blue
    <input type="radio" value="red" />red
</RadioGroup>

Props

• name: String - the name to be set to all radios in the group

• value/defaultValue - the value that should be checked in the group (controlled/uncontrolled)

• labelStyle - a style for the radio label

• inputStyle - a style for the radio input

• checkedLabelStyle - a style for the checked radio label

• checkedInputStyle - a style for the checked radio input

• onChange: Function(value, event) - the function to be calle when the radio group value changes. NOTE: first param sent to this function is the new value, not the event object, as usual

• renderRadio: Function(props, index, arr) - you can customize how each radio item is rendered in the group using this function. NOTE: it is called with 3 params, so not intended to be directly used with a React factory.

Example:

   //NOT LIKE THIS
   <RadioGroup renderRadio={React.DOM.label} />

   //BUT like this
   function renderRadio(props, index, arr){
       return <label {...props} />
   }

   <RadioGroup renderRadio={renderRadio} />

   //or
   function renderRadio(props, index, arr){
       if (index < arr.length - 1){
           props.style.borderBottom = '1px solid blue'
       }
       props.style.display = 'block'
       //we can skip returning something
       //if we only want to modify props/styles
   }

If the renderRadio function returns undefined, we assume you just wanted to modify the props before rendering, which is ok, so we fallback to the default implementation: <label {...props}/>

• items: Array

  The items prop can be an array of strings/objects or mixed. If an array of strings, the strings will be used as both value and label. If objects, item.value will be used as a value, and item.label as a string:

  Example:

      var items = [
          {label: 'Green', value: 'green'},
          {label: 'Blueish', value: 'blue'},
          {value: 'red'} //'red' will be used as both value and label
      ]
  
      //or
      var items = ['green', 'blue', 'red']

  If an array item is an object, besides value and label, it can also have a style property and a checkedStyle property.

  var items = [
      'red',
      {
          label: 'Blue',
          value: 'blue',
          style: { color: 'blue'},
          checkedStyle: { color: 'blue', background: 'red'}
      }
  ]

• children - if the component specifies children, the radio group children will not be generated from items, but will be what you specify in the children prop

If you have a ref to the react-radio component, you can also call group.getValue() to get the current value of the radio group.
