javascript - 如何从 Material UI 文本字段查看密码？

Question

我的代码工作正常，当我在密码字段中写入时，文本被隐藏。有没有办法添加一个功能，让用户可以选择查看密码(如果他/她愿意)？

  const [email, setEmail] = useState('');
  const [password, setPassword] = useState('');

  return (
          <div>
         <div className='main-content'>
         <form className="form" noValidate autoComplete="off">
                {[{ label: "Email", state: email , type: "text", function: setEmail},
                { label: "Password", state: password , type: "password", function: setPassword},
                  ].map((item, index) => (
                  <div>
                    <TextField
                      id="outlined-basic"
                      key={index}
                      label={item.label}
                      variant="outlined"
                      type= {item.type}
                      onChange= {e => item.function(e.target.value)}        
                    />
                    <br></br><br></br>
                  </div>
                )
                )}
         </form>
         </div>
       </div>
        );
      }

您可以根据某些真/假状态更改值的类型。

// Add these variables to your component to track the state
const [showPassword, setShowPassword] = useState(false);
const handleClickShowPassword = () => setShowPassword(!showPassword);
const handleMouseDownPassword = () => setShowPassword(!showPassword);

// Then you can write your text field component like this to make the toggle work.
<TextField
  label='Some label'
  variant="outlined"
  type={showPassword ? "text" : "password"} // <-- This is where the magic happens
  onChange={someChangeHandler}
  InputProps={{ // <-- This is where the toggle button is added.
    endAdornment: (
      <InputAdornment position="end">
        <IconButton
          aria-label="toggle password visibility"
          onClick={handleClickShowPassword}
          onMouseDown={handleMouseDownPassword}
        >
          {showPassword ? <Visibility /> : <VisibilityOff />}
        </IconButton>
      </InputAdornment>
    )
  }}
/>

在您的示例中，您使用循环来遍历您的字段。用我的示例替换您的文本字段会将切换添加到所有字段。这(可能)不是您想要的，因此您必须找到一种不同的方式来呈现这些字段。

import { TextField, InputAdornment, IconButton } from "@material-ui/core";
import Visibility from "@material-ui/icons/Visibility";
