Q1730 How can I remove options from a select list based either on the text property value or the value property value?

Try:

<html>

<head>

<script language="JavaScript"><!--
function removeOptionsByText(selectName, text) {
  for (var i=selectName.options.length-1; i>=0; i--) {
    if (selectName.options[i].text == text) {
      selectName.options[i] = null;
    }
  }
}

function removeOptionsByValue(selectName, value) {
  for (var i=selectName.options.length-1; i>=0; i--) {
    if (selectName.options[i].value == value) {
      selectName.options[i] = null;
    }
  }
}
//--></script>

</head>

<body>

<form>

<select name="selectName">
<option value="fine">test
<option value="test">leave this alone
<option value="okay">test
<option value="xyz">test
<option value="test">okay
