Using the Distinct Option

Question

Hey Guys,
I'm calling the following dataset like this:
var dsProducts = new
Spry.Data.XMLDataSet("data/product_list.xml", "/products/product");
The XML looks like this:
<?xml version="1.0" encoding="iso-8859-1"?>
<products xmlns="
http://www.products.com/products">
<product id="1">
<productModel>dada</productModel>
<productName>Dada 5000</productName>
<productDesc>Cool product</productDesc>
<imgName>dada.jpg</imgName>
<productNum>1234</productNum>
<productPrice>555.00</productPrice>
</product>
There's about 50 products. What I want to do is populate a
dropdown box with the productModel values. However, there's only a
total of 3 different ones, so I'm trying to pull the DISTINCT
values of that node. Right now the dropdown has 50 values in it,
and I can't figure out how to use distinct with it.
Any ideas?
Thanks.

Hello,
The Spry preview that will be available in couple of weeks (I
hope :) ) contains the ability to specify for the distinct a field
or a list of fields to be only considered. Right now the entire row
is checked to be distinct in the dataset and if any difference
exists in any of the fields then the record is added.
I think the easiest method to control the value selected when
a link is clicked is to add on that link the following JS code:
onclick="document.getElementById('theSelectElementID).selectedIndex
= '0'; return true;"
which will select the first option of the
"theSelectElementID" select element.
