Reset to default 2Get all input field in state, after reset state with help of setState() function.

Edited your codesandbox to get it working: https://codesandbox.io/s/m4x7j1jm19
Note that if you set fields to an empty object in your cancel function, then you have to be sure to set each field to an empty string in your input values (I just did the first field):
value={this.state.fields["event_bucket"] || ''}
I remend making the input a controlled input. Try this on for size:
class ComponentName extends Component {
constructor(props){
super(props)
this.state = {
myValue: ''
}
this.clearData = this.clearData.bind(this)
this.handleChangeTextbox = this.handleChangeTextbox.bind(this)
this.onSubmit = this.onSubmit.bind(this)
this.onCancel = this.onCancel.bind(this)
}
clearData(){
this.setState({
myValue: ''
})
}
handleValidation(){
return 'whatever'
}
handleChangeTextbox(e){
this.setState({
myValue: e.target.value
})
}
onSubmit(e){
e.preventDefault();
if(this.handleValidation()){
alert("Form submit")
this.clearData()
}
}
onCancel(e){
e.preventDefault()
alert("Cancel")
this.clearData()
}
render() {
return (
<div>
<textarea value={this.state.myValue} onChange={this.handleChangeTextbox} />
<button type="submit" className="btn btn-success active" onClick={this.onSubmit}><b>Create</b></button>
<button type="button" className="btn btn-warning"><b>Preview</b></button>
<button type="button" className="btn btn-danger" onClick={this.onCancel}><b>Cancel</b></button>
</div>
)
}
}
