Pass a hidden field value based on which button is clicked with JavaScript

Question

I have a form with two buttons, each with onclick = this.form.submit(). I have a hidden field in the form, and I would like the value of the field to be different based on which

Answer 1

use Prototype :-)

But in all seriousness:

1. Add an id to the hidden field

2. Before you submit the form in each handler:

   document.getElementById("hiddenId").value = "mySpecialValue";

   //or (depending on which onclick handler you are in)

   document.getElementById("hiddenId").value = "myOtherSpecialValue";

3. Submit the form the same way you are now.

Recommended ex:

...

function buttonA_clickHandler(event) {
    document.getElementById('hiddenId').value = whatever;
    document.getElementById('theForm').submit();
}

repeat for the other button.
