How to fix the "Unable to type in input" issue in React Hello World! When we work with forms in , we may encounter an issue where we won't be able to type in the input field/text box if the property is set. I will be showing what is the actual issue and how I fixed it. React value Scenario Requirement I have an API that would require three fields, namely Email, Name, and Message, which need to be passed in the body of the API. In the UI, we would be getting those values in an input field or text area and would be using a button to trigger the API call. The structure expected in the API is something like this: {
"email": "testxyz@test.com",
"name": "Test",
"message": "Hi, this is a test message."
} Implementation In the React app, I've created a component with 2 input fields to get the and , a text area for getting the and a button to trigger the API call and send the 3 values. This is what the component looked like: name email message import { useState } from "react";
import callApi from "../axios/axios";
import "./contact.scss";
const Contact = () => {
  const payloadInitial = {
    sender: "",
    email: "",
    message: "",
  };
  const initialClass = "form-input";
  const [payload, setPayload] = useState(payloadInitial);
  // Captures Sender name
  const setName = (name) => {
    const temp = payload
    temp.sender = name
    setPayload(temp)
  };
  // Captures Email
  const setEmail = (email) => {
    const temp = payload
    temp.email = email
    setPayload(temp)
  };
  // Captures Message
  const setMessage = (message) => {
    const temp = payload
    temp.message = message
    setPayload(temp)
    checkCanSend();
  };
  // Triggers API call on button click
  const sendMessage = (evt) => {
    evt.preventDefault();
    callApi
      .post("/email", payload)
      .then((res) => {
        console.log("Response: ", res)
      })
      .catch((err) => {
        console.error("Something went wrong: ", err)
      });
  };
  return (
    <div className="form-container">
      <h2 className="form-title">Write to me</h2>
      <div className="form-container">
        
        <label>Your Name</label>
        <input
          type={"text"}
          aria-label="Your Name"
          value={payload.sender}
          onChange={(e) => setName(e.target.value)}
        ></input>
        
        <label>Your Email</label>
        <input
          type={"email"}
          aria-label="Your Email"
          value={payload.email}
          onChange={(e) => setEmail(e.target.value)}
        ></input>
        
        <label>Type in your message</label>
        <textarea
          rows={8}
          value={payload.message}
          onChange={(e) => setMessage(e.target.value)}
        ></textarea>
        
        <button onClick={(e) => sendMessage(e)} className="send-button">
          Send Message
        </button>
      </div>
    </div>
  );
};

export default Contact; In the above component, we are listening to the change of input fields using the event and setting the new values to the state. onChange payload Issue The above code was causing an issue where I was not able to type more than one character. Solution The solution for the issue is: In the onClick function, instead of storing the state in a temp variable, changing the value in the temp, and setting temp to the state, we should . update the state directly In our case, let us consider the function. The function should be changed like this: setName const setName = (name) => {
    setPayload((prev) => ({
      ...prev,
      sender: name,
    }));
    checkCanSend();
  } Now, the state is updated directly without having any temp variables. Now, we can type on the input field. The final code would be: import { useState } from "react";
import callApi from "../axios/axios";
import "./contact.scss";
const Contact = () => {
  const initialClass = "form-input";
  const [payload, setPayload] = useState(payloadInitial);
  // Captures Sender name
  const setName = (name) => {
    setPayload((prev) => ({
      ...prev,
      sender: name,
    }));
    checkCanSend();
  };
  // Captures Email
  const setEmail = (email) => {
    setPayload((prev) => ({
      ...prev,
      email,
    }));
    checkCanSend();
  };
  // Captures Message
  const setMessage = (message) => {
    setPayload((prev) => ({
      ...prev,
      message,
    }));
    checkCanSend();
  };
  // Triggers API call on button click
  const sendMessage = (evt) => {
    evt.preventDefault();
    callApi
      .post("/email", payload)
      .then((res) => {
        console.log("Response: ", res)
      })
      .catch((err) => {
        console.error("Something went wrong: ", err)
      });
  };
  return (
    <div className="form-container">
      <h2 className="form-title">Write to me</h2>
      <div className="form-container">
        
        <label>Your Name</label>
        <input
          type={"text"}
          aria-label="Your Name"
          value={payload.sender}
          onChange={(e) => setName(e.target.value)}
        ></input>
        
        <label>Your Email</label>
        <input
          type={"email"}
          aria-label="Your Email"
          value={payload.email}
          onChange={(e) => setEmail(e.target.value)}
        ></input>
        
        <label>Type in your message</label>
        <textarea
          rows={8}
          value={payload.message}
          onChange={(e) => setMessage(e.target.value)}
        ></textarea>
        
        <button onSubmit={(e) => sendMessage(e)} className="send-button">
          Send Message
        </button>
      </div>
    </div>
  );
};
