Yeah, the file fields was me too.
You don't do a server request, you do it all client-side with
javascript. I didn't test this, but here's the general idea:
<script type="text/javascript">
window.emailFieldCount = 1;
function addField() {
var div = document.getElementById("fieldContainer");
div.innerHTML += '<input name="email' + ++window.emailFieldCount +
'" /><br />';
}
</script>
<div id="fieldContainer">
<input name="email1" /><br />
</div>
<a href="javascript:addField();">add field</a>
Walking through the code, we've got a single field hard coded in the
page, along with a field count stored in a variable
(window.emailFieldCount), which is initalized to one (because of the
one hard coded field). When you click the 'add field' link, the
addField() function is called, which find the div that contains the
input fields, and adds another field to the end, incrementing the
field count variable and using it to set the field name to be unique.
I've opted to use innerHTML rather than the DOM for appending the
fields for simplicity's sake; either should work.
This is a first little window into building javascript RIAs, where the
entire app no longer resides on the server, but part of the UI
controller has moved to the client.
