I'm wondering about the .childNodes property, I have the code below, and for some reason I get 18 children, while 6 are HTMLInputElements as expected, and the rest are undefined. What is this about? Is there an efficient way to iterate over the input elements?
<html>
<head>
<script>
window.onload = function(e){
form = document.getElementById('myForm');
alert(form.childNodes.length);
for(i=0; i<form.childNodes.length; i++){
alert(form[i]);
}
}
</script>
</head>
<body>
<form id='myForm' action="haha" method="post">
Name: <input type="text" id="fnameAdd" name="name" /><br />
Phone1: <input type="text" id="phone1Add" name="phone1" /><br />
Phone2: <input type="text" id="phone2Add" name="phone2" /><br />
E-Mail: <input type="text" id="emailAdd" name="email" /><br />
Address: <input type="text" id="addressAdd" name="address" /><br />
<input type="submit" value="Save" />
</body>
</html>
