Results (totals) row in spry datasets

Question

Hi everybody.
I spent a lot of time on the problem how to get row with
result of the spry dataset.
And I found it:
Javascript code:
// This is our dataset
var dsSpecials = new Spry.Data.JSONDataSet("paysdata.cfm",
{path:"rows"});
// This is dataset for results
var dsSums = new Spry.Data.JSONDataSet();
// Loading empty array to results
dsSums.loadDataIntoDataSet("[]");
var myObserver = new Object;
// Calculate function will run each time when data will
change
myObserver.onDataChanged = function(dataSet, data) {
calcTotals(); }
dsSpecials.addObserver(myObserver);
var calcTotals = function() {
var tsums = [];
var rows = dsSpecials.data;
// ... here you calculate what you need...
dsSums.loadDataIntoDataSet(Spry.Utils.serializeObject(tsums));
And now, the final part - HTML code:
<div spry:region="dsSpecials dsSums"
class="SpryHiddenRegion">
<table>
<tr spry:repeat="dsSpecials">
</tr>
<tr spry:repeat="dsSums">
</tr>
</table>
</div>

It identifies the column. In Step 2, you can select each
column and
change its name in the Column Name field at the top of the
wizard.
Without a column name, the Spry data set has no way of
identifying the
data you want to display.
