Textbox and Selectbox

[OmiCron]

Hello good people. I need some help here. I dont know if it's possible, but i got 1 textbox and 1 selectbox.

What i want is:

If the textbox is not empty, gray out/disable the selectbox, and if something in the selectbox is selected, gray out the textbox.

is this possible, and if so, how do i do it?

Many thanx

Perhaps something like this:

<form action="" onsubmit="return false;">
  <p>Choice:
  <select size="1" name="choice"
   onchange="return checkControls(this, other)">
    <option>[select one]</option>
    <option>apples</option>
    <option>bananas</option>
    <option>cantaloupe</option>
  </select><br>
  Other:
  <input type="text" name="other" size="20"
   onchange="return checkControls(choice, this)"></p>
</form>

<script type="text/javascript">
<!--//
function checkControls(sel, txt) {
  if(sel.selectedIndex < 1) {
    txt.disabled = false;
    if(/^\s*$/.test(txt.value)) {
      sel.disabled = false;
    } else {
      sel.selectedIndex = 0;
      sel.disabled = true;
    }
  } else {
    txt.value = "";
    txt.disabled = true;
  }
  return true;
}
//-->
</script>
