Convert inches to centimeters

Question

Hi,
I'm trying to convert inches to centimeter on the fly, but
nothing seems to work.
<div spry:detailregion="products">{products::height} x
{products::width} x {products::depth} in</div> works fine
but:
<div
spry:detailregion="products">{function::convertMetric}
cm</div><script type="text/javascript">
function convertMetric(region, lookupFunc)
// Format the number in the price column so that it
// becomes a string that starts with a dollar sign,
// and ends with a number that has 2 digits after
// the decimal point.
return "$" +
parseInt(lookupFunc("{products::height}")).toFixed(2);
</script>
Copied right off the API site generates an error.
How is the supposed to work?
Thanks

Hi,
You still haven't mentioned what the error is that you are
getting. Also, look at your SpryData.js file that is deployed on
your testing site, at the top of the file is a comment that says
the version number of the file and the release it is from. What
does it say?
By error, did you mean that you are getting a zero from your
alert? Or are you getting an actual error message in the browser?
The data in a data set will persist, after you load it, until
you either load new data or destroy the data set.
The data set loads its data asynchronously, and only after
you call the loadData() function on it ... if a data set is bound
to a region or detail region on the page, loadData() is
automatically called for you at the time the regions are identified
and processed on the page.
So depending on when you called you getRowCount() and
alert(), there may have been no data loaded yet.
If I understand you correctly, you are simply trying to fill
in a detail region with the dimensions calculated dynamically:
var products = new Spry.Data.XMLDataSet(...);
products.setColumnType([ "width", "height", "depth"],
"number");
<div
spry:detailregion="products">{function::convertMetric}
cm</div>
<script type="text/javascript">
function convertMetric(rgn, lookupFunc)
return lookupFunc("{products::height}") * 2.54 + " x " +
lookupFunc("{products::width}") * 2.54 + " x " +
lookupFunc("{products::depth}") *2.54 + " cm" ;
</script>
You can see a working example of the {function::myFunc} here:
http://labs.adobe.com/technologies/spry/samples/data_region/Function_colon.html
but it only works in version of SpryData.js released with
Spry 1.6.1 and later. You can get the latest copy here:
http://labs.adobe.com/technologies/spry/includes/SpryData.js
If you are using an earlier version of SpryData.js, then you
either need to update to the latest, or use a custom column which
you can find a sample of here:
