Field looping

[UKuser]

Hi,

How do I loop through 5 fields each named field,
field2,field3,field4,field5 within this statement?

document.forms[0].field|whatgoeshere?|.value

For example:
for (i = 0; i < ct; i++)
{
name = escape(document.forms[0].field('1').value);
alert(name);
}

This will fail, but I need to know how I should include a changing
element after the field name titled i within my looping statement.

Thanks

A

for (var es = document.forms[0].elements, i = es && es.length; i--
{
name = escape(es["field" + i].value);
alert(name);
}

You SHOULD NOT encode the field values if you use a `form' element to submit
them. The proprietary escape() also is deprecated in favor of the standards
compliant encodeURI() and encodeURIComponent() methods; the former should
only be used as a fallback where the latter methods, as determined by proper
feature detection, are not available.
