I have made 4 radio buttons for 1 question. I have made 2 buttons submit and clear input. When I submit the form after clicking on clear input it does not clear the checked buttons to unchecked how can I do that using reset
function ?
contactform.js:
import React, { Component } from 'react';
class ContactForm extends Component {
constructor(props){
super(props);
this.state = {
age:'',
gender:'',
health:'',
name:'',
email:'',
info:'',
fitness:''
};
}
setAge(checkedValue){
console.log(checkedValue);
this.setState({
age:checkedValue
})
}
setGender(checkedValue){
console.log(checkedValue);
this.setState({
gender:checkedValue
})
}
onChangeTextBoxGender(event){
this.setState({gender: event.target.value})
}
savedata(age, gender, health, name, email, info, fitness){
let newcontent = contentref.push();
newcontent.set({
age:this.state.age,
gender:this.state.gender,
health:this.state.health,
name:this.state.name,
email:this.state.email,
info:this.state.info,
fitness:this.state.fitness
});
}
reset(){
this.setState({
age:'',
gender:''
})
}
render() {
return (

export default ContactForm;
See screenshots:
Give a checked attribute for you radio button. Change
<label>
<input
type="radio"
name="age"
onChange={this.setAge.bind(this,'>=25 yrs')} />
{' '}
>=25 yrs
</label>
to
<label>
<input
type="radio"
name="age"
checked={(this.state.age == '>=25 yrs')}
onChange={this.setAge.bind(this,'>=25 yrs')}/>
>=25 yrs
</label>
you can control what is selected using the state, below find and example (btw, it is not a good practice generate functions inside the render function because it will cause unnecessary rerenders)
class App extends React.Component {
state = {
selectedValue : ''
}
optionSelected = (e) => {
console.log(e.target.value)
this.setState({
selectedValue : e.target.value
})
}
reset = (e) => {
this.setState({
selectedValue : ''
})
}
render () {
const { selectedValue } = this.state;
return (
<div>
<div>
<input
type="radio"
name="age" value="A"
onChange={this.optionSelected}
checked={selectedValue === 'A'}/> A
</div>
<div>
<input
type="radio"
name="age"
value="B"
onChange={this.optionSelected}
checked={selectedValue === 'B'}/> B
</div>
<div>
<input
type="radio"
name="age"
value="C"
onChange={this.optionSelected}
checked={selectedValue === 'C'}/> C
</div>
<button onClick={this.reset}>reset</button>
</div>
);
}
}
ReactDOM.render(<App/>, document.querySelector('#root'))
