form, input, onclick

When do things like this:

  <form id="formtest" action="#">
    <p>
      <input id="buttontest" type="button" name="testbutton" value="Button Test"
         onclick="testingButton(this.form)" />

what needs to passed is: this.form

For the called fuction (this case testingButton),
do it like thie:

    function testingButton(note) {
        alert(note.testbutton.value);

It will print, Button Test


Above won't work for multiple inputs.
For multiple inputs, do this:

<form id="formtest" action="#">
    <p>
    <input id="buttontest" type="button" name="testbutton" value="Button Test"
      onclick="testingButton('test')" />

For the called fuction, do it like this: 

<script type="text/javascript">
    function testingButton(note) {
        if (note == 'test') {
            alert "here! 2");
        }
