Hi Steve,
When it comes to rendertag, it is not recommended to use rendertag to get
the element value. The reasons are explained in other threads in this
forum. If you want to compare an element value from the same page, simply
throw the placeholder into the rendertag if statement.
Yes, there is a rendertag solution for figuring out even or odd, but it
consists of 5 if statements, I think it is somewhere here in this forum
too, or solutionsexchange.info.
No, there is no math operation in rendertag.
For what you wanted to do, it can be solved more easily using
JavaScript/JQuery
$('#mylist div:even').addClass('even');
$('#mylist div:odd').addClass('odd');
Best,
-Jian
