Submit form with MUI

Question

I am trying to build a simple form in MUI with login and password TextField and a Button to submit the form. What's the best way to handle events on the Button and submit the form?

Answer 1

Add type="submit" to a Material UI button element, such as a RaisedButton, and it will work as a submit button when clicked on. When the form is submitted, it will trigger the onSubmit on the form and run the handleSubmit callback.

class MyForm extends React.Component {
  constructor() {
     super();
     this.state = {id: null};
  }
  handleChange = (event) => {
     this.setState({id: event.target.value});
  }
  handleSubmit = (event) => {
     //Make a network call somewhere
     event.preventDefault();
  }
  render() {
     return( 
        <form onSubmit={this.handleSubmit}>
          <TextField floatingLabelText="ID Number" onChange={this.handleChange} />      
          <RaisedButton label="Submit" type="submit" />
        </form>
     )
  }
}

You can have a look at react-hook-form library. It manages the form state for you automatically, the only thing you need to do is specify the name for each field and validation rule if needed:

const { register, handleSubmit } = useForm();
const onSubmit = (data) => alert(JSON.stringify(data, null, 4));

return (
  <form onSubmit={handleSubmit(onSubmit)}>
    <Stack m={2} spacing={3}>
      <TextField label="First Name" inputProps={register('firstName')} />
      <TextField label="Last Name" inputProps={register('lastName')} />

      <TextField select label="Gender" inputProps={register('gender')}>
        <MenuItem value="male">Male</MenuItem>
        <MenuItem value="female">Female</MenuItem>
        <MenuItem value="furry">Furry</MenuItem>
      </TextField>

      <FormControlLabel
        control={<Checkbox />}
        label="Is developer?"
        {...register('isDeveloper')}
      />

      <Button variant="contained" type="submit">
        submit
      </Button>
    </Stack>
  </form>
);
