Question

is it possible to put a javascript variable in to the spry if
statement to test?
like <div spry:if="javascriptvar == {ds_RowNumber}"....
thanks.

Hi rogerfreak,
When the region processes a spry:if, it simply takes the
value of the spry:if attribute, replaces all of the data references
in it with real values from the data set and then evals the result
(executes the string).
So you can do something like:
<script>
var ds1 = new Spry.Data.XMLDataSet("foo.xml", "/foo/bar");
var gMode = 5;
function GetMode()
return gMode;
</script>
<div spry:region="ds1">
<ul spry:if="gMode == 5">
<li spry:repeat="ds1">{name}</li>
</ul>
<div spry:if="gMode == 12" spry:repeatchildren="ds1">
{name}
</div>
</div>
In the example above the list markup will be written out if
gMode is 5, but if it is 12, it will write out the div markup.
You can also call functions:
<div spry:region="ds1">
<ul spry:if="GetMode() == 5">
<li spry:repeat="ds1">{name}</li>
</ul>
<div spry:if="GetMode()== 12"
spry:repeatchildren="ds1">
{name}
</div>
</div>
