How do I exclude certain form fields upon submission of the form without disabling the field

Question

If I have a form with the following 3 fields:

First Name Last Name Date Of Birth

When the user fills in all 3 fields and submits you will get the URL

http: //fakeURL.php?firstName=Fred&lastName=Flintstone&DateOfBirth=2/5/1952

However, if the user only fills in First Name and Date Of Birth you will get

http: //fakeURL.php?firstName=Fred&lastName=&DateOfBirth=2/5/1952 (where lastName has no value)

How do I achieve

http: //fakeURL.php?firstName=Fred&DateOfBirth=2/5/1952 (where lastName and value are removed from the URL)

I don't want to disable the input field upon using onsubmit. Is there a better way than disabled the input field?

Please help...

Answer 1

Just remove the "name" attribute from the input element.

// using jQuery
$('#inputId').removeAttr('name');

// native Javascript
document.getElementById('inputId').removeAttribute('name');
