Newbie Question on the Basics

[Vik Rubenfeld]

(I hope I'm in the right forum. This is the site linked to as the forum
for Scriptaculous - http://wiki.script.aculo.us/scriptaculous/).

I have a total newbie question. I'm studying a sample application that
uses Scriptaculous for Autocomplete. It does this by putting the
following into the header of the web page:

----------
window.onload = function () {

new Ajax.Autocompleter("metal_name", "autocomplete_choices",
base_url+"add_metals/ajaxsearch/", {});

$('metal_search_form').onsubmit = function () {
inline_results();
return false;
}
}
----------

And here's the HTML:

----------
<?php
$this->load->view("header");
?>
<h2><?= $title;?></h2>
<form id="metal_search_form" method="post" action="<?=
site_url('add_metals/ajaxsearch');?>">
<div>
<label for="metal_name">Search by metal name </label>
<input type="text" name="metal_name" id="metal_name" />
<input type="submit" value="search" id="search_button" />
<div id="autocomplete_choices" class="autocomplete"></div>
</div>
</form>
<div id="metal_description" style="display:none;">
<p>Enter your function above</p>
</div>

<?php
$this->load->view("footer");
?>
----------

Here are my questions:

1) I don't see anything in the HTML that calls the JavaScript. What is
it in the HTML that calls the Javascript?

2) Autocomplete has to work by calling a function after every keypress.
What is it in the HTML that calls the Javascript after every keypress?

I guess those are both the same question.

Thanks very much in advance to all for any info!

While someone might be able to help you here, you'll probably have
better luck in the rails spinoffs forum.

Good luck.
