这是我在render方法中用于登录用户的表单。

<form onSubmit={this.handleSubmit}>

            <Avatar classname={classes.avatar}>
              <LockOutlinedIcon />
            </Avatar>
            <Typography component="h1" variant="h5">
              Sign in
            </Typography>

            <TextField variant="outlined" margin="normal" fullWidth id="email" label="Email Address" name="email" 
              onChange={this.handleEmailChange}
            />
            <TextField variant="outlined" margin="normal" fullWidth 
              name="password" onChange={this.handlePasswordChange}
            />
            {loginError && (
              <Typography component="p" classname={classes.errorText}>
                Incorrect email or password.
              </Typography>
            )}

            <Button type="button" fullWidth variant="contained" color="primary" classname={classes.submit}
              onClick={this.handleSubmit} >
              Sign In
            </Button>

        </form>

以下是我的句柄提交方法

handleSubmit = () => {
    const { dispatch } = this.props;
    const { email,password } = this.state;
    dispatch(loginUser(email,password));
  };

在单击按钮时提交有效，但在Enter键上无效。请注意，我正在使用import Button from "@material-ui/core/Button";
