How to store the value of a checked checkbox in an array in React.js

Jason 000

I am using react-checkbox-group from " https://www.npmjs.com/package/react-checkbox-group " . I want to add 4 checkboxes on a web application, each checkbox has a different value. Then, I want to store these values ​​in an array. I have the code below for what I want to do, but not sure how to handle the "onChange" event. Now the array 'baseballItems' initially has all the items, I want the unchecked items to disappear, but I'm willing to change it so it's empty and the checked boxes are populating the array.

`this.state = { baseballItems: ['bat','baseball', 'shoes', 'cap']}

...

<CheckboxGroup
checkboxDepth={2}
name="baseballItems"
value={this.state.baseballItems}
onChange={(event) => this.setState({ baseballItems: [event.target.isChecked]})}>
<label><Checkbox value="bat"/> bat</label>
<label><Checkbox value="baseball"/> baseball</label>
<label><Checkbox value="shoes"/> shoes</label>
<label><Checkbox value="cap"/> cap</label>
</CheckboxGroup>`
m51 
this.state = { baseballItems: ['bat','baseball', 'shoes', 'cap']}

...

<CheckboxGroup
  checkboxDepth={2}
  name="baseballItems"
  value={this.state.baseballItems}
  onChange={(items) => { this.setState({ baseballItems: items }); }}
>
    <label><Checkbox value="bat"/> bat</label>
    <label><Checkbox value="baseball"/> baseball</label>
    <label><Checkbox value="shoes"/> shoes</label>
    <label><Checkbox value="cap"/> cap</label>
</CheckboxGroup>

There is a similar example in the READMEreact-checkbox-group
