Uncheck the boxes

Question

I think this is a very stupid doubt, but I am stuck with that. I have several switches, and I want to remove all the switches as soon as I click on another switch. How can I achieve this in a reaction?

var options = [{id:1,nm:"Appointment fixed"},{id:2,nm:"Call later"},{id:3,nm:"Wrong number"},{id:4,nm:"Don't call again"},{id:5,nm:"Call later"}];
{options.map((item,i) => {
                     return (
                        <div onChange={(i)=>this.callOptions(i)}>
                           <label className="radio-inline"><input type="radio" value={i} ref={'ref_' + i} value={item.id}/>{item.nm}</label>
                        </div>
                      )
                  })}

Answer 1

Give a common name tag for you. Edit

<input type="radio" value={i} ref={'ref_' + i} value={item.id}/>

to

<input type="radio" value={i} name="abc" ref={'ref_' + i} value={item.id}/>

You can use a managed input or an unmanaged input. Below is an example for each of the solutions.

Before posting this, let me add some useful tips and links for you:

• refs . , . , refs; .

• key , . . ,

• . , .

• value .

, , . - :

constructor() {
  super();
  this.state = {checkedRadio: null};
}

changeRadio(e) {
  this.setState(checkedRadio: e.target.value);
}

var options = [{id:1,nm:"Appointment fixed"},{id:2,nm:"Call later"},{id:3,nm:"Wrong number"},{id:4,nm:"Don't call again"},{id:5,nm:"Call later"}];

{options.map((item,i) => {
  return (
    <div key={item.id} onChange={(i)=>this.callOptions(i)}>
      <label className="radio-inline"><input type="radio" checked={this.state.checkedRadio == i} ref={(el) => this["myRadioRef" + i] = el} value={item.id} onChange={this.changeRadio} />{item.nm}</label>
    </div>
   );
 })}

    <div key={item.id} onChange={(i)=>this.callOptions(i)}>

In addition, for a stateless component, if you want to deselect a radio element, you can also use the property checked:

const renderRadioGroup = data.map((radio, i) => {
    return (
        <span key={i}>
            <input
                className={radio.class}
                id={radio.id}
                type="radio"
                name={radio.value}
                value={radio.value}
                onChange={e => {
                    onChange(e, itemKey);
                }}
                checked={defaultChecked === radio.value}
            />
            <label htmlFor={radio.id}>{radio.label}</label>
        </span>
    );
}

in this case it is defaultCheckedpassed as a props and used as a variable in the class.
