Why does this cause IE to throw a JS error?

function focusInitialField() {

var fields = document.getElementsByTag Name('input');

var firstfield = fields.getAttribute( "text")[0];

if ((firstfield) %26amp;%26amp; (firstfield.value === '')) { firstfield.focus(); }

}

Then you'd call to the function onload.

function focusInitialField()

{

var fields = document.getElementsByTagName('input');

for ( var x = 0; x %26lt; fields.length; x++ )

{

if (fields[x].getAttribute('type') == "text" %26amp;%26amp; fields[x].value == "")

{

fields[x].focus();

break;

}

}

}

[edit]

i like this idea. it will loop through all the input elements and set focus on the first text box.
