Get name of form element
<p>i have this simple JS for validating form, can someone tell me how to get name of field (you know, name=""), it should be where NameOfSomefield is now :S I tried with <code>someField.tagName</code> but no luck...</p>

<pre><code>function validateForm(){
    var someField = document.forms["nameofofrm"]["someField"].value;
    if (someField==null || someField=="") {
        alert("You cannot leave blank this field: ".NameOfSomefield);
        return false;
    }
}
</code></pre>
