Ensure that the form does not submit or display any empty or blank inputs

I am experiencing two difficulties in my code

  1. How can I prevent submission when the input field is empty upon clicking the submit button?

  2. For the select-1 and select-2 JavaScript, how can I assign custom names to their values? For example, if AS400 is selected for select-1 (with the value option-1), I want it to be named AS400. Similarly, when selecting AS400 New Account for select-2 (value option-1a with class option-1), I want it to be named AS400 New Account.

$(function() {
  
  $('#select-2 option:not([default])').wrap('<span/>');
});

$('#select-1').change(function() {
  $('#select-2 span > option').unwrap();
  $('#select-2 option:not(.' + $('#select-1').val() + ', [default])').wrap('<span/>');
  //console.log($('#select-2').val());
});

...
//Code snippet continues
...

</script>

Answer №1

To ensure data is present in the field when submitting, you can use the HTML attribute required on the input field without needing additional JavaScript functions.

If any fields should be optional, simply omit the required attribute.

<div>
      <form>

        <label>Full Name
          <input type="text" placeholder="Type your name..." required />
        </label>
        <br/><br/>

        <label>Employee ID
          <input type="text" placeholder="Type Id Here..." required />
        </label>
        <br/><br/>

        <label>ONE ID (Formally Authenticator ID)
          <input type="text" placeholder="Type Id Here..." required />
        </label>
        <br/><br/>

        <label>Badge Number
          <input type="text" placeholder="Type Badge Here..." required />
        </label>
        <br/><br/>

        <label>Enter your Email:<input type="text" placeholder="Type Here..." required/></label>
        <br/><br/>

        <input type="submit" value="Send" />

      </form>
    </div>
