I am trying to build a very simple form structured with (ideally) a set of radio buttons, a set of checkbox and then another set of radio buttons. These are three different sections of the form I am trying to build.
I would like to keep the current form but I want the two set of radio buttons to be completely independent. First I am not sure they are with the current structure of the code. Second, for some reason, I can pick one option in the first set of radio buttons but the second set seems to be disabled (I can't pick neither long-running nor event-driven).
How can I achieve that? Thanks.
import React, { Component } from "react";
class App extends Component {
constructor() {

this.state = {
customer: "individualDev",
programmingmodel: "long-running",
isWebService: false,
isBatchJob: false,
isAiMl: false,
isDatabase: false,
isWorker: false,
};
}
onValChange = (event) => {
this.setState({
customer: event.target.value,
});
};
onCheckValChange = (e) => {
this.setState({ [e.target.name]: e.target.checked });
};
onSubmitForm = (event) => {
event.preventDefault();
console.log("state", this.state);
};
render() {
return (

CodePudding user response：
You should use the same logic that you have already implemented in the checkboxes. Set a name attribute to the radio button and set your state by the [event.target.name]: event.target.value method. Like so:
import React, { Component } from "react";
class App extends Component {
constructor() {
super();
this.state = {
customer: "individualDev",
programmingmodel: "long-running",
isWebService: false,
isBatchJob: false,
isAiMl: false,
isDatabase: false,
isWorker: false,
};
}
onValChange = (event) => {
this.setState({
[event.target.name]: event.target.value,
});
};
onCheckValChange = (e) => {
this.setState({ [e.target.name]: e.target.checked });
};
onSubmitForm = (event) => {
event.preventDefault();
console.log("state", this.state);
};
render() {
return (
<div className="App">
<form onSubmit={this.onSubmitForm}>
<br/>
