Q554 How can I determine if a checkbox on a form exists?

Try:

<form name="myform">
<input type="checkbox" name="myfield">
</form>

<script language="JavaScript"><!--
if (document.myform.myfield)
    alert('myfield exists');
else
    alert('myfield does not exist');
if (document.myform.myotherfield)
    alert('myotherfield exists');
else
    alert('myotherfield does not exist');
//--></script>

I found that I had to use the eval expresssion:

eval(document.formName.fieldName)
