button - 单击按钮即可停用输入 react

Question

我有这个基本组件，我希望每当单击按钮时停用或激活文本字段。我怎样才能实现这个目标？

这是我的示例代码:

import React from "react";
import Button from 'react-button'

const Typing = (props) => {
    var disabled = "disabled";
    var enabled = !disabled;

  const handleUserInput = (event) => props.onUserInput(event.target.value);
  const handleGameClik = (props) => {

      disabled = enabled;
  }
  return(
      <div>

          <input
              className = "typing-container"
              value = {props.currentInput}
              onChange = {handleUserInput}
              placeholder=" ^__^ "
              disabled = {disabled}/>
          <Button  onClick = {handleGameClik}> Start Game  </Button>
          <Button> Fetch Data </Button>

          </div>
          );
};

使用状态的简化解决方案可能如下所示:

class Typing extends React.Component {
  constructor(props) {
    super(props);
    this.state = { disabled: false }
  }
  handleGameClik() {
    this.setState( {disabled: !this.state.disabled} )
  } 
  render() {
    return(
        <div>
          <input
                className = "typing-container"
                placeholder= " type here "
                disabled = {(this.state.disabled)? "disabled" : ""}/>
          <button  onClick = {this.handleGameClik.bind(this)}> Start Game  </button>
          <button> Fetch Data </button>
        </div>
    );
  }
};
