复选框默认选中并在 React.js 中禁用也不起作用

checkbox defalut checked and also disabled in React.js not working

您好,我正在尝试制作一个默认选中并在 React 中禁用的切换​​按钮(复选框)。 但不知何故,如果我只输入 checked={true} 它将被选中,但是当我添加 disabled="disabled" 时,开关按钮未被选中和禁用(即使有 checked 属性)。有人可以建议吗?谢谢

 <label htmlFor="disabled-on" className="switch__label">
            <input
                type="checkbox"
                name="disabled-on"
                id="disabled-on"
                checked={true}
                disabled="disabled"  /* if added disabled it's not working with checked" */
                className="switch__input switch__input--disabled-on"
            />

您的代码可能在其他地方有问题,请检查此代码 - 一切正常。

class TodoApp extends React.Component {
  constructor(props) {
    super(props)
  }
  
  render() {
    return (
      <div>
        <ul>
          <li>
          <label htmlFor="disabled-on" className="switch__label">
             custom checkbox 1
              <input
                  type="checkbox"
                  name="disabled-on"
                  id="disabled-on"
                  checked={true}
                  disabled="disabled"
                  className="switch__input switch__input--disabled-on"
              />
          </label>
          </li><li>
          <label htmlFor="disabled-on" className="switch__label">
